ATTEMPTING TO DRIVE MY BUGATTI VEYRON FOR THE FIRST TIME — Transcript

Mark McCann attempts to drive his rebuilt Bugatti Veyron, facing clutch slipping issues and exploring solutions with gearbox experts.

Key Takeaways

  • Custom-made clutches may not perfectly replicate original Bugatti parts, causing performance issues.
  • Oil flow and heat dissipation are critical in high-performance clutch design to prevent slipping.
  • The Veyron’s transmission software is finely tuned to original clutch characteristics and may struggle with new materials.
  • Self-learning software adaptations can potentially resolve clutch engagement issues without hardware changes.
  • Patience and careful driving are essential during the clutch adaptation process to avoid further damage.

Summary

  • Mark McCann rebuilt the Bugatti Veyron gearbox without Bugatti's official help and faced clutch slipping problems after the first drive.
  • The new clutch was custom-made as Bugatti refused to sell original parts, leading to differences in material and design.
  • Rob Barnes, an expert who helped design the original Veyron clutch, explains the clutch slipping is due to oil hydroplaning between plates.
  • The original clutch design included cutouts to dissipate heat, which the new clutch lacks, causing friction and slipping issues.
  • The car's transmission software is calibrated for the original clutch, causing mismatch and confusion with the new clutch material.
  • Rob suggests the car might self-learn and adapt the clutch engagement through driving and temperature-based learning processes.
  • The team attempts to warm the transmission and let the car perform a 'kiss point learn' to adapt clutch pressure and improve performance.
  • Driving carefully to avoid overheating and burning the clutch is critical while the car adapts to the new clutch material.
  • The video includes detailed technical explanations of the clutch mechanics, software adaptation limits, and troubleshooting steps.
  • Despite challenges, the team remains hopeful the car will self-correct without needing to dismantle the gearbox again.

Speaker A
I attempted to rebuild a broken gearbox on my Veyron without Bugatti's help. After rebuilding this amazing car and driving it for the first time, we sadly found out we still have a few problems.
00:12
Speaker A
The new clutch that we had replaced was slipping. Yeah, that feels very slippy now.
00:17
Speaker A
So, frustratingly, six months of work may have been a waste. Today, I'm going to find out if this is fixable or do we have to go all the way back to step one?
00:27
Speaker A
If so, this car is going to have to be split apart and the gearbox removed all over again. Well, fingers crossed that's not the case. But first, let's find out what's causing the issue. In order to solve the issue, first we need to
00:40
Speaker A
understand the problem. So, we met back up with Rob Barnes, Extracardo gearbox employee. Importantly, he helped design and build the Veyron clutch and gearbox back in 2006. So, hopefully he can shed some light on our next steps. Right, we
00:57
Speaker A
clearly have clutch lift. Yeah, on pull away. As we set off from standstill, you can hear the engine revs and struggles to pull away. We are having to give it way more revs than usual to force the clutch
01:10
Speaker A
to disengage. So, as we put all that throttle on, the clutch is slipping and for sure it's going to get hot. The thing is our clutch shouldn't be slipping as we have fitted a brand new one. But it wasn't an original Bugatti
01:24
Speaker A
part as they wouldn't sell me one. So we had to make it ourselves. But why do we think my clutch is slipping? Because obviously Pascal took the old clutches out and reverse engineered them. So we can see that even by inspection of the color
01:39
Speaker A
of the two plates, you can see that the new material is more carbon-based and the older material is more paper-based with some carbon parts in it. And if you look at the surface finish of the two,
01:51
Speaker A
you'll see that there are some operations on the original clutch that are not present on the new clutch.
01:58
Speaker A
So that's like the cutouts. It's the way that the segments are put together. Can you explain the cuts and why we have the cuts?
02:05
Speaker A
To be able to get rid of the heat from the clutch surface, we need to pass through the clutch a lot of oil from the center hub of the clutch. It's thrown out. In this case, we're pumping up to
02:16
Speaker A
32 liters a minute of oil to go through the clutch to remove the heat, which is good. But in terms of passing that amount of oil through the clutch, it then actually gives the clutch problems with generating friction in the first
02:29
Speaker A
place. If you imagine driving on a dry surface with barely legal road tires like Reese's, take it easy where you've got effectively the minimum number of cuts in the tire.
02:41
Speaker A
If you drive that on dry surfaces, you'll get really good performance. If I now go and spray water on the surface, Reese is in the hedge because the rubber's not touching the floor. It's sitting on the water, not the tarmac.
02:53
Speaker A
Exactly. It's hydroplaning. Yes. So that explains why the engine is revving high to be able to move forward.
02:59
Speaker A
The oil is basically sitting on the faces of the clutch plates, stuck and not able to go anywhere. Obviously, Pascal knew about the pattern as he took the old ones out. But technology has moved on. It's 20 years later. DCT
03:14
Speaker A
clutches are not made like they were anymore. So, Pascal made a clutch that he knows already works with a DCT gearbox producing a 1,000 horsepower. But my Veyron just doesn't seem to like it.
03:28
Speaker A
So, how do we get around that? That would be to, let's say, do a MK2 version of this material.
03:41
Speaker A
That means split the car and start again. That's one option which, to be honest, is the worst case. And the other thing that it could be is that clearly the characteristic of the original clutch. I tested that
03:56
Speaker A
characteristic and I mapped the characteristic of that clutch from torque to pressure. You did that?
04:04
Speaker A
Yes. But we can't change that map. We can't change that map in the software. No. However, in the software to allow for the variability between the clutches, there is an adaptation in there.
04:18
Speaker A
Right. So, we talked about this in the last video. The graph which Rob's business partner Andrew explained to us.
04:25
Speaker A
Basically, the car's computer knows how hard to push the clutch to get the power to translate to the wheels. So, right now, our car's brain is confused. The clutch that we've put in doesn't match the software, the clutch feel, the
04:39
Speaker A
thickness, the material. It's all different from when this car was last used all those years ago. Suddenly, it's woke up and everything's changed. So, Rob's hope and our last chance is that the car might not be pushing the clutch
04:54
Speaker A
plates hard enough. So, the oil is hydroplaning. It's just sitting on the top surface. Now, if, and this is a big if, if the car can push the plates harder, it would force the oil out between the plates faster. But we have
05:08
Speaker A
no access to the transmission ECU to change the software and shouting at it won't help either.
05:15
Speaker A
What we do by sitting the car and allowing it to do its kiss point learns, it moves the bottom pin of that line.
05:24
Speaker A
There are quite a number of other pins in that line that can only move when the car is driving.
05:30
Speaker A
So driving might help. Driving the car may help. Yeah, but we're burning the clutch out surely, is we? Um, the pullaways would need to be gentle, but then when it starts driving in gear, the clutch feels like it's closed, but it actually isn't
05:43
Speaker A
closed. It's slipping slowly. So, we've got to be gentle. Basically, getting it up to that point. Yes. It goes into a steady state condition while driving and slipping and then the clutch control software within the transmission controller can say, "Okay, that doesn't
05:59
Speaker A
look like it's in the right place." And start to try and correct its knowledge of the clutch by itself.
06:04
Speaker A
By itself. The only one thing that I don't know is clearly I would have put a characteristic maximum in for what I would have expected from a standard clutch.
06:16
Speaker A
So instead of 45°, we'd ideally allow for that to be 40° or 50°.
06:21
Speaker A
Exactly. Yeah. But Rob thinks there is a chance that this car can learn, adapt, move, relocate the points to teach itself to make the 2026 material plates work without building up too much temperature, which will overheat and again burn our clutch out. We're not
06:42
Speaker A
entirely sure if this will work, but realistically right now we have nothing to lose, so we might as well just give it a go. Right. So, we can do some initial tests. Yeah, we can get the car or the transmission to a condition
06:55
Speaker A
where it can do its initial learn. So it's kiss point learn sat still. Sat still. Yeah. Okay. So we are trying to get the car to move the kiss point which is the point where the car starts to creep forward, the bottom part on our
07:08
Speaker A
graph to learn the new materials, to learn the pressures. So we start off in the center of the tolerance limit line to give us the best chance as we work up the torque line. But first, we need a
07:20
Speaker A
Jane pint-sized person. Right now, obviously, the door is not working. And that's what we got to be careful of because if we break that, we're not getting a new one of them with a Bugatti badge on.
07:32
Speaker A
Who's getting in it? Right. I think you've got disability allowance because of... Yeah. So, I think it's between me and you.
07:40
Speaker A
Rock, paper, scissors. I am going rock. Okay. So, you got to figure out if I'm a liar or not.
07:48
Speaker A
I don't lie. Right. In order for the car to learn the perfect kiss point, Rob and Andrew back in 2006 programmed that the gearbox needed to be at 40° before it started doing its own thing.
08:06
Speaker A
Okay. So, the plan is that we start the engine and we allow the transmission temperature to get up to above 40° centigrade. So, it won't do anything cold or... It's not going to do anything cold. No,
08:18
Speaker A
it needs to get up to a base temperature on the drivetrain, which I think is 40°.
08:24
Speaker A
And it needs to get up to 40° centigrade. And then it needs for Chris to do effectively nothing to the car.
08:30
Speaker A
And it should then say, "Okay, driver's not doing anything. I'm in a good condition." It should start to learn itself the kiss p...
08:40
Speaker A
This is ridiculous. Now, in theory, when the gearbox is warm and sat still idling, after exactly 30 seconds, it would do a bit of its own homework. 20 years ago, Rob wrote this into the gearbox brain to make it adapt, to
08:54
Speaker A
learn, to protect itself in its own spare time. This is crazy. And fingers crossed this works because I would love in this video to ask for the biggest hypercar specialist to value my finished car and see if my 900k gamble has paid
09:10
Speaker A
off. We'd be able to show you all the costs and calculate if we have made money or lost money. But first, it's got to run and drive.
09:19
Speaker A
What we on, boss? 38. Could you not have set it to 38? You didn't really think forward, did you?
09:27
Speaker A
I didn't. Although, to be honest, back in the day, I probably would have just rec-alibrated it to 36.
09:34
Speaker A
So, will we see it learning now? We should see it learning now. Yes. So you'll notice that the engine speeds at engine speed and you'll see that the input shaft one and input shaft two have just stopped. So the clutch is now
09:45
Speaker A
completely open and in a minute you'll see it the the software will say okay we we're good conditions and you'll see it start to pick one of the shaft speeds up as it's learning.
09:57
Speaker A
So that's adapting then so that it's like learning to be perfect every time. Yeah, it's learning all the time. We try and do adaptations as often as possible.
10:04
Speaker A
No way. Yeah. And that will obviously reduce the wear of the clutch then or make the clutch work better.
10:11
Speaker A
It makes makes it behave repeatably. Makes it behave the same every time. So I guess as the clutch wears out then that will alter each time. So yeah, very clever.
10:21
Speaker A
Yeah. Well, they're both cracking on now then. Yeah. So that that one's midlearn at the moment.
10:30
Speaker A
That's just picked up to engine speed. This car, this gearbox, every day it gets better. It's like the ultimate machine. So, remarkably, it's doing it.
10:39
Speaker A
It's busy cleverly making itself a perfect setup in its own spare time without telling it to do it. It's moving pressures, adapting points to make sure it sets off perfectly each and every time it pulls away. And then tomorrow or
10:54
Speaker A
next week or next month, as a clutch wears and changes, it would do it again and again and again. It's mind-blowing this car. like this gearbox. This car, every single day it gets more impressive. It's even self-learning. It
11:10
Speaker A
really is the ultimate machine. Right, Rob and Chris are now going to take the car out. I am not going to drive it. And it's quite a simple reason is I don't know what is good and bad. I know what a
11:21
Speaker A
slipping clutch feels like, but I don't know how much this I don't know where this should feel like. They're going to go from here, get onto the motorway, get some constant speeds, and hope that this clutch now starts to adapt. Did you say
11:36
Speaker A
six and seven gear? Seventh gear. So, how long you go out? Go out for like an hour or something or Yeah, something like that. Just I think if you you need to hold it for about 30 seconds in each gear under constant
11:48
Speaker A
conditions and and then move points. So, we need to adapt a lot of points and it will be 30 seconds run on each each point but to the motorway and then up and down the motorway.
11:59
Speaker A
So, here we go. We know that the initial kiss point, the pull away point has moved. And now we're going to try and drive constant revs and speed and let the clutch ECU learn right the way up the graph. Rob said in the software that
12:13
Speaker A
every time you drive at the same revs and gear constantly for exactly 30 seconds, it tweaks itself. Bit by bit, we are hoping this car will self-learn to work in harmony with our new clutch material. Otherwise, it's split the car
12:30
Speaker A
again and start over. But also, we still can't buy any Batti original plates. But but for now, that's tomorrow's problem.
12:39
Speaker A
Yeah, the creep tree feels really nice now. Yeah, that's no, you know, I'm just already they can feel the kiss point.
12:48
Speaker A
And now creep is coming into our window. The car, it's learning. This is starting to look good. Really good. But what we need is constant speed and constant revs. But right now, we are struggling.
13:02
Speaker A
There's quite a lot of tracking on it, isn't it? It's probably probably not perfect conditions for this, is it? If they keep stopping and starting before the clutch ECU has leared the ideal adaption points, it's just going to burn
13:12
Speaker A
the clutch out. It will go into self-protect mode and throw up a fault code.
13:17
Speaker A
I think it's something that could be done at night. Yeah, I think Yeah, Matt or I will go out in it at night.
13:23
Speaker A
So, they decided to wait for a better opportunity when there's no traffic. So, we go home then, come back another day.
13:30
Speaker A
Come back another day. Is that a song? Go home now and come back another day.
13:36
Speaker A
If it's not, it should be a song. You started something. Go home now and come back another day.
13:43
Speaker A
The Bugatti's broken, but it's going to be okay. Yeah, we'll do that next couple of evenings. You know, a Sunday night or something like that when it's we know it's going to be quiet.
13:53
Speaker A
So, we could come back like Monday or something. Yeah. Good for Monday. It's midnight Sunday. There's no traffic and everyone is in bed apart from our test driver Matt and he is ready to go constant speeds and constant revs so the
14:12
Speaker A
gearbox brain can start to learn and adapt further up that graph. So Matt had a little circuit 2 miles in varying gears and revs constant smooth speed and then round the island green mid green or dark green. So he isn't stopping and
14:31
Speaker A
again and again and again. To start with, you can hear the slip, but 40 minutes in, Matt could feel that it was improving.
14:48
Speaker A
Hello. Me better already. Do that a clean version of the race. Caught blowing me governor.
14:59
Speaker A
That's better already. Up and down, round and round, lap after lap, giving our car and this clutch the best chance. Fifth gear, 3,000 RPM, but for 30 seconds constantly. The same for 4,000 revs, 30 seconds again, and then
15:19
Speaker A
5,000 revs. Rinse and repeat in all the gears and right through the rev range.
15:24
Speaker A
Just making sure we hold the same revs so the car cleverly adapts. But just as things were going well, the car was throwing up a fault into a reduced power limp mode.
15:38
Speaker A
Back to 200 horsepower. But crazily right now that's actually an advantage as it's easier to regulate being a bit lazy. Apart from the measly 300 horsepower when you should have a 101, the gearbox feels perfect. No slick, nothing. Look
16:01
Speaker A
down in second. I think we did it, boys. I think we all did it.
16:07
Speaker A
This really is looking positive. So, we got the team back to HQ. Oh, and then how did it go?
16:14
Speaker A
Uh, it was brilliant, actually. Gear change was brilliant. wasn't slipping at all. It was biting.
16:20
Speaker A
That's a fixed to me as a non-software expert. It felt spot on, right? What's next?
16:27
Speaker A
Okay. So, it's good news so far. It's good news so far. Yeah. Um I'd quite like to go out again and assess it after what we felt last week.
16:36
Speaker A
It'd be nice to go out and see. So, you think you'll be able to tell the direct difference if it's if it's changed?
16:41
Speaker A
Yeah, I think both of us will be able to tell. Yeah. So, the moment of truth. The experts jumped in to give us their verdict. Do we split the car again or are we okay to jump the veil?
17:03
Speaker A
So far with Matt's late night and the lads trying different scenarios, we have done 110 km of clutch adaption. But the big question, can they feel an improvement? Everyone, please cross your fingers.
17:22
Speaker A
What we thinking? It's certainly got a lot better. So, since the last time we drove it. So, noticeably noticeably better. Yeah.
17:30
Speaker A
100%. Not It's not 100%, but it's still got a bit flare up off around about second gear, but just general shifting, it's 100 times better than it was. Cuz I feel like if we're here now, we've not stood
17:42
Speaker A
still or go backwards. If we've gone forwards, surely we just keep going forwards. So, it's coming out. I think so.
17:52
Speaker A
What an absolute proper top result. What amazes me about this car is every time we start it, every time we drive it, it's learning. It's adapting without even asking it. It's like the It's like the perfect employee. Can't you be more
18:07
Speaker A
like that? You just pay me 900 grand on a well. But I'm so happy. It's like like it's not just great for me. It's it's Jamie.
18:15
Speaker A
It's Pascal. It's Furongers. And also, if you think about this, Rob and Andrew, if they hadn't wrote this adaptation, the learning path into that gearbox ECU 20 years ago, we'd be in a right mess right now.
18:35
Speaker A
We've got a few more jobs to finish today. Then we're going to take it to a few hypercar specialists to get it valued. And I'm also going to tell you exactly how much it's cost us to get to
18:46
Speaker A
this point where we've got a working car. And then we'll see if it was a good decision or maybe a bad decision. So, let's go through the final things which we need to fix. Well, I say we, I mean
18:58
Speaker A
Chris, but it's still a we. and hopefully he's fixed that pipe, but we'll get on to that a little bit later.
19:08
Speaker A
So, the car's locked itself when we did the first drive. It's done it like anti-hijack. So, it's locked.
19:14
Speaker A
Antihijack. So, currently the doors are stuck shut. The key doesn't work. The remote doesn't help. And even when you pull the inside or outside door handle, it makes no difference. It's not locked. It's proper locked. and I am too tall and many times
19:30
Speaker A
broken to start doing a daily jukes of hazard. Now, the car is also going into a limp mode. It's only given about 200 to 300 horsepower. And frustratingly, that's not showing up a light on the dash, which would tell us in the engine
19:43
Speaker A
management system. So, unfortunately, when we plug it in, we will have no direction of where to start. And the rear wing has no communication with the car. We did trick the sensors to lift right up in the last video, but right
19:56
Speaker A
now that wing is stuck in position and it's at a horrible weird droop down angle. Can we do anything with that? So, it's like stuck up like that. Yeah, you can sort that out cuz that's where it's supposed to be, isn't it? Should be hot.
20:09
Speaker A
So, before we get this car valued, we have three things which we need to fix.
20:13
Speaker A
So whilst Chris is diagnosing those problems and we are nearly at the end of this mammoth project, I want to explain what I have learned about this car over the last 6 months. I knew the Bugatti Veyron was special, but let's together
20:26
Speaker A
understand why this car cost Volkswagen £5 million to produce. Now, in 1997, while sat on a high-speed train traveling across Japan, this man Ferdinand Pek, the CEO of Volkswagen, drew this actual picture on the back of an envelope. This here is the very first
20:52
Speaker A
breaths of the Veyron. His idea was not a V12 like the opposition McLaren F1, Ferrari, and Lamborghini. He was going Billy big balls and dreamt up a W18. Yes, a crazy 18 pistons and cylinders, which they did actually make here as a prototype. Can
21:13
Speaker A
you imagine how much money that that is worth today? He then decided on a slightly different way with a musive 8 L W16 with four turbochargers, even saying that in 2026 it still sounds absolutely ridiculous.
21:30
Speaker A
He then set his team some brutally specific targets which the car had to achieve to make production. They were allowed zero compromise. First up, it had to have over 1,000 horsepower, which was pretty much double of any other road
21:46
Speaker A
car at that time. Also, it needed to be the fastest. He told them clearly that Veyron had to hold the world record top speed, over 400 km per hour. He also told them it needed luxury like a Bentley and he said it needed to be
22:05
Speaker A
reliable at whatever the cost. This was a team board meeting in 2001 and back 25 years ago this was madness. What he was requesting wasn't even possible. It was literally just some words, not reality.
22:21
Speaker A
And they made a dream fiction. Insanity an actual reality. This is so much more than any car you've ever seen. I mean, it's as easy to drive as a normal car, but it goes like a bullet. Nobody knew, but they had
22:37
Speaker A
created the very first hypercar, which made for some crazy trivia facts. At top speed, this car drains the full fuel tank in under 12 minutes, which is a good job because at that top speed, even with the bespoke engineered Michelin
22:55
Speaker A
tires, they give up after 15 minutes. The heat is that intense. The foldup brake generates more stopping power than a normal car. That's without even considering the brake discs and pads. It has 10 radiators to try and keep it
23:13
Speaker A
cool. It carries 200 L of various fluids to even operate. And that engine sucks in 47,000 L of air a minute. And the big one, they made4 million pound loss on every Veyron that they sold. This wasn't about profit.
23:33
Speaker A
This was a flex that VW were the best at making cars in the world. They were making a statement. Pigeon chest out and chin held high. And somehow Mark from Reddic, our little family, has one. And that's probably the craziest fact of it
23:51
Speaker A
all. So, let's crack on and get this truly incredible car finally back to my house to see its new loving home. So, let's get back to our list and let's finish these last three tasks.
24:12
Speaker A
Now, to make things even more weird, mine and my Armstrong's cars both had misfires, both had pump failure, and both had weak accumulators. But they also had the exact same door lock problem. Right. Do you know you told me
24:26
Speaker A
that the door got locked in? M just tell everyone how you got it open.
24:32
Speaker A
Okay. So, I had to take the cap off. Yeah. I had to drill out the lock.
24:40
Speaker A
Um that didn't work. Couldn't get that. I looked it up with everything. Couldn't get honestly had the car stripped.
24:46
Speaker A
Couldn't get it. I was on the verge of giving up. I've got the CCTV footage as well. I was like, I don't know how I'm going to do this. Whacked the door in my hand and then next thing it opened.
24:56
Speaker A
So, what are you going to do? Put a screwdriver in your back pocket. Tap the door. Pull the handle.
25:06
Speaker A
So tap the door. Have you put the screwdriver in your pocket? Yeah. You haven't put a screwdriver in your pocket? Yeah. I'll put that in your back pocket.
25:14
Speaker A
Now imagine if this worked superb. Now obviously we're going to do this the furlong away. We don't just throw parts at it. We strip to understand why it has gone wrong to save us in the future as there's no doubt that this is going to
25:37
Speaker A
happen again. We were lucky when it happened our first time because we were inside the car. But we can see there's nothing obvious broken or any bent part.
25:46
Speaker A
That will move. That moves. So that's work now. That's opening. So, we're thinking it just needs some good oldfashioned grease.
25:56
Speaker A
It's probably dry from being left inside rusty workshops for years. This where you take it apart, it goes back together again.
26:03
Speaker A
This part's just pinged off. Can we not just leave this alone? I feel like we've seen enough. We've seen enough. Yeah.
26:14
Speaker A
If you just take those bits off just so you understand how it all works completely. Strip apart the motor. any chance you can find out it works on somebody else's.
26:26
Speaker A
But even after making it moist, the lock was still jamming occasionally. And oddly, it works perfectly off the car.
26:33
Speaker A
The only part I didn't have when it was off the car was the handle.
26:37
Speaker A
So, we have narrowed it down to this cable joining the lock mechanism to the door assembly handle. Chris adjusted a little bit of tension off. He's got his head in his hands. Right, Mark. locked.
26:51
Speaker A
Now there you go. Hate mark. Problem solved. Sweet. And to make sure that we had fixed it, once we unstuck the passenger door, we used the same technique to make sure my side was working.
27:12
Speaker A
Good work, team. We did. We did a lot there. I think I think that was mainly down to us. I think the model support was a nice simple fix with zero parts having to be bought, which might be important
27:23
Speaker A
later when I show you all the bills that I have had to pay to make this car back to perfection. Small niggly failures like this is what could make a Veyron ownership so expensive. We have heard stories like Carl's wobbly window
27:37
Speaker A
switch. It was £95,000 plus V80. Found the part and they were 89. This is because these manufacturers as a whole, they replace. They tend not to fix or adjust. They unbox and fit new expensive parts. Imagine what would have
27:57
Speaker A
happened if I had taken my door to be fixed at the big boys. I might have had to sell something very precious. And there's lots of other stories just like that all over the internet.
28:07
Speaker A
I thought you'd really get a kick out of these Bugatti service records, huh? It's $400 an hour. $1,000 just to look at your airbag light. Yeah, just to look at it.
28:17
Speaker A
Yes. Not to work on it or fix it, to look at it. Yes. 37 grand to do all those services.
28:26
Speaker A
I love the Bugatti brand. And in January when we had they and Ron, I was the person who wanted to pay top money to get my car fixed at the main dealer. But as you all saw, not even a call back. And I really don't
28:46
Speaker A
think that we deserve that. But looking back now, was this actually a great big fat positive? The journey that we have been on together and a team of engineers designing making fixing remembering a team which got back together like some
29:02
Speaker A
sort of epic boy band reunion. So now we have choices like furongers. I know it's the perfect time to own one of these cars. We've seen some age related issues which are now not so expensive to fix.
29:16
Speaker A
Right. Next, the rear wing and the limp mode. Right. What's going now? You're making nervous.
29:23
Speaker A
Door's done. So, now we're going to get the spoiler sitting a bit more. Yes.
29:28
Speaker A
Proud. Now, this is a very temporary but effective fix. These nylon bushes just clip in and fight against gravity to hold the spoiler up at a much nicer angle.
29:39
Speaker A
It's a bit flatter, isn't it? Yeah, definitely mate. Definitely better 100%. So, number two is a tick. Definitely only temporary, but we are still actively working to find a solution for those sensors. And to be fair, we are
29:52
Speaker A
nearly there. And finally, limp mode. For some reason, it's restricted to pretty much 250 horsepower. And greedily, I want it all.
30:03
Speaker A
We've got no engine light. I guess that would make life a lot easier. would do to a point because it it it opens the front door effectively to the to the house of the car.
30:14
Speaker A
So, we're going back door. We're going back door. Front door's locked. No error codes. So, we we're going to read values bank to bank.
30:25
Speaker A
See if anything, you know, you got four values of the airflow meter. If three of them are reading a five, say five, and one's reading one, we know we're in the right area. In the last video where we
30:38
Speaker A
fixed the misfire on cold start, we replaced the math sensors, but we couldn't get in time the proper Bosch equivalent Bugatti ones. So maybe the ones we fitted just aren't perfect. We have got the proper airflow mates to put
30:51
Speaker A
on. So we got to take all this back off again. No, we're going to go through the wheel arches.
30:56
Speaker A
Oh, back door again. Yeah, back door again. Um James is going to give me a hand with that.
31:00
Speaker A
What? Back door. Okay, the back door. Double team. James, you're all right. Back door in.
31:06
Speaker A
Uh yeah, I can do. Yeah. Sweet. What a team. Yeah, we'll try anything tricky.
31:12
Speaker A
So, we're looking for the two bottom sensor readings to be similar, which they are on this side of the engine.
31:19
Speaker A
First ECU. I know what it could be. Yeah, go for it. That pipe. It ain't that pipe. That pipe's perfect.
31:26
Speaker A
That level was not dropped once. What? I mean, have you changed the bike yet?
31:31
Speaker A
No, I haven't changed. How do you know it's not? won't be changed when we see the car again. It's going to be changed, right?
31:37
Speaker A
The only way to know it's not the pipe though is to change it. Look at look at this difference in value.
31:42
Speaker A
Have you found something? Yeah. But on the other side, they are miles apart. So, we're going to change them, but via the back door.
31:57
Speaker A
I'm on the camera now, so I got to go like this and miss it all. Well, I've got you. Please subscribe. The easy quick way to access the sensors is by removing the carbon fiber wheel arch liner. What sort of car has carbon fiber
32:12
Speaker A
wheel arch liners? Hilarious. We now have access to the math sensors and we can swap them out for the original Bosch OEM to exactly match the Bugatti service parts. And whilst Chris is on the one side, James is teaming up on the other.
32:26
Speaker A
So, let's find out if that works. And whilst the car was jacked up, Chris took away our teasing ammunition with a swap over of a very special pipe.
32:36
Speaker A
Present for you as you've been on my case so much about it. I want it above the car in the garage.
32:45
Speaker A
Yeah, for the record everyone, he's changed it now. Changed it. I reckon you were getting quite emotional with the with the grease.
32:52
Speaker A
Fed up reading the comments. Just relentless comments. I had someone ask me at Silverston.
32:59
Speaker A
Have I done it now? So, with everything swapped, we now need a test driver. And after owning a Bugatti since Christmas, it's finally my turn to get into the driver's seat.
33:15
Speaker A
Honestly, this blows me away. 20 years ago, I saw this car, and never did I think I would own one. Never mind one which looks as good as this. These past 6 months have been slow. Everything has taken time. But that's because we wanted
33:30
Speaker A
everything to be as good as it possibly could be. So after all that doubt, let's see just how bloody great my spaghetti and Ron actually is from behind the steering wheel.
33:46
Speaker A
I'm not driven anymore. Come on, let's go. his eyes. Yeah. That's why you never driven it.
33:55
Speaker A
Never driven it. Oh, I'm glad I'm the first person in the passenger seat. I only feel in front of J.
34:04
Speaker A
I've never driven it. I tell you one thing I will say about it. Suspension. That's really good.
34:10
Speaker A
It is. It doesn't feel very rattly. Not rattly at all. Like it feels fine. Very windy here, isn't it?
34:17
Speaker A
Yeah. You got to get a new rubber for that. Yeah. See, that is normal. That is how they pull away.
34:21
Speaker A
That doesn't feel that bad at all. That's how they pull away. You got to got to get off the clutch, haven't you?
34:29
Speaker A
Suppose there's a little bit there. No, genuinely, Mark, I wouldn't drive this and say it feels different.
34:39
Speaker A
Honestly, even right now, 20 mph will do me. It's been an absolute emotional roller coaster. highs and lows you could have never imagined from a tin can on wheels. It's brought me laughter, tears, smile, and despair in the same day. It's
34:58
Speaker A
been one hell of a journey, and to be honest, it's been a privilege to share it with you guys. I feel your passion, the comments, the messages, and the questions have been amazing. But a lot of you did doubt me, and rightfully so,
35:12
Speaker A
as it's not your average sensible decision. But I've always known that somehow one day this car would see the road again and in the summer, but I just wasn't quite sure which summer. So, is this car ready? Will Jane finally get to
35:28
Speaker A
see the spaghetti Veay and Ron in one piece? Especially as it's a fullblown shiny spoon. Can it at last please come home?
35:41
Speaker A
It's still bright. Yeah, go. You got now. can feel it. It's definitely gone. Yeah, you got brand. Yeah.
35:54
Speaker A
Well, we have done it together. All of us 100% fully working Batti Veyron Mansori Persank. As you know, when I took this risk, my plan was to rebuild this car at a fraction of the cost to if I had taken it to Batti. Then
36:11
Speaker A
potentially I could end up with a car way cheaper than any other Veyron for sale. Well, now it's done. I'm going to tell you exactly how much I have spent to fix it. And then we can calculate if
36:23
Speaker A
I have made or lost money. Finally, this thing is fixed after all this time, months and months and months. Everything is working. It's shiny. It's in one piece. The gearbox is fixed. The clutch is fixed. Everything is perfect. And I
36:40
Speaker A
am excited to get this home. And anybody who rides shotgun in this car has got to have one of those in their pocket at all times. Basically, no fish and chips. If you touch it, there's greasy fingerprints. Now, we're going to get it
36:52
Speaker A
valued. And hopefully I haven't lost any money cuz unfortunately 4.4 million of you guys in the UK have because $442 billion has been lost due to fraud. As you know on this channel, we hate scammers. So that's why for this video
37:08
Speaker A
we have partnered with protect my data who has sponsored this video. Right. Also surprise now registration plate. I love registration plates and I've actually had this 10 years when I used to race side by side boogies and it was
37:23
Speaker A
on the camper. Ready? Yeah. Typical. That's it. Gee, thank you for all your inputs.

38:23
Speaker A
Now, it's time to find out how much this car is worth after all the effort we have been to. There were a lot of people worried that this car would never be back together. And one person especially who thought that this might have been a
38:36
Speaker A
step too far. You're buying a cancer patient. You're buying You're buying a terminally ill car.
38:41
Speaker A
It's risk. It's very very risky. It's very very risky. But with big risk come big rewards.
38:48
Speaker A
But now Carl is going to be one of the three people to give us their honest opinion, a true market valuation to what this car is worth in the market today.
38:58
Speaker A
I'm so excited to see what he thinks to this car. He's heard the weekly progress reports. He has witnessed firsthand the stresses and smiles along our journey.
39:12
Speaker A
It's here. Wow man. Well firstly congratulations. Thank you so much. Um, I've never seen that. Obviously, I've not seen this one before.
39:25
Speaker A
And look, it's like it's one whole thing. I can do my hair in here and everything. Unbelievable.
39:35
Speaker A
Your trousers, by the way. Thank you very much. Does that sound a bit weird for a M?
39:38
Speaker A
A little bit. Whilst Carl is doing a close inspection, let me show you the other evaluators. We have Matt from Furlonger Cars. He has seen the entire rebuild process. And today's third valuers, that is a massive difference.
39:57
Speaker A
Geez, completely different to what it was when we last saw it. Are the people who started this whole roller coaster, Ollie, my friend, who specializes in discrete client offmarket hypercar sales, and his business partner Chris, who is also Mansori UK. They are
40:14
Speaker A
the perfect people to value this Mansori Veyron. compared to what we first saw when we walked into that garage to what we're seeing now. It's it's it's day and night completely completely different. I say the shock of seeing it in two pieces
40:26
Speaker A
was definitely a shock for both of us. But we had a vision. God, you were right.
40:32
Speaker A
Right, let's get into the figures. Initially, what are Veyron's worth in general? Where's this sit and where does the market sit?
40:40
Speaker A
Well, the market's in the last 12 months changes quite a lot to be honest.
40:44
Speaker A
There's a lot more interest. A lot of collectors didn't buy them and now have bought them.
40:49
Speaker A
And do you think that's because of running costs? I think the running cost has made a difference. I think there's also a 20 year anniversary definitely made an in difference. To me, one of the most amazing things is how there's nothing
41:01
Speaker A
missing. Yeah. Yeah. I think the the whole thing with that car is, you know, when you went there, you saw the bolts and cups and, you know, how many different dealers and people that have been to, I think it was going to be a high
41:14
Speaker A
probability. There was some special stuff missing. So, it's nice because everything's gone back together. It's a all the big bits are still It's a complete car, isn't it?
41:25
Speaker A
I've known of this car for for ages since it came into the country and no one none of the owners have ever really spent the money on it and looked after it the way it should have been. So, I'm
41:38
Speaker A
glad it's with you and you know you can you can treat it how it it it needs to be.
41:47
Speaker A
Yep. That's fine. Pass the test. So, thanks for 11,600 quid. It's done 12,000 km.
41:55
Speaker A
So, it's done like 8,000 miles. So, what are you going to do? You're going to sell it to me.
42:00
Speaker A
So, let's find out what the hypercar experts think my Bugatti Veyron is worth. Mansor.
42:07
Speaker A
Yeah. How does that alter cars usually sort of like does it increase value, decrease middle of the road?
42:14
Speaker A
It depends on the spec. You know, if someone orders a pink with pink color and it's going to be difficult to sell on afterwards.
42:21
Speaker A
Yeah. But with something like this where it's rarity value, Mansur's got a very strong name in this sort of thing, I I think it's definitely with it looking like this as well. Now, I think it increasing value definitely.
42:34
Speaker A
There's definitely been some mixed opinions in the comments. If you don't know who Mansori are, they modify and customize cars, but they are well known for sometimes being very extreme. Larry and some of the color combinations best looked at in the dark. Well, I think the
42:51
Speaker A
Mansori bit, as I said at the beginning, when you're buying it, it's always going to be a a Marmite situation. If you want a Mansori, you're going to be desperate to buy one and you've got to find one.
43:01
Speaker A
If you just want to buy a normal value, you might not like the Mansori thing.
43:05
Speaker A
So, that is always going to be a a flip to a buyer. What demotes a value of a car? Condition, mileage, rarity. They're the three things. And it's it's very rare. It's obviously low mileage, which we were surprised about, weren't we? But
43:18
Speaker A
that's another point that was good about it. And that probably does ring too true with the condition of it. Yes.
43:23
Speaker A
So Mansori do two versions of the the Veyron. Have you seen the like the actual Mansori Veyron?
43:31
Speaker A
Yes. Okay. That is that's wild. Yes. This you would never know in a in a in a million years that this is got any kind of a kit. It hasn't got a kit. All that's Mansor about this car is the
43:43
Speaker A
finish. They Mansur turned the car into what they call a Persang. It's got no kit on it. Do I think it being this spec configuration helps or hurts it? I think it depends on the buyer.
43:57
Speaker A
I think for you it helps it. Yeah. I I didn't I wanted something quite like classic but modern looking.
44:05
Speaker A
Yeah. Not like a chocolate brown or Yeah. Yeah. Yeah. So, that is all good news. Now, as a reminder, 6 months ago, I paid £900,000 for this car in two pieces. parts spread everywhere with a broken gearbox in
44:20
Speaker A
Holland. At the time, the market values were between 1.3 and 1.6 million. And obviously, I have spent a lot of money repairing this car, which we will go through bit by bit after we have our free values. What do you think really
44:37
Speaker A
now that's worth? A lot more than 900,000. But seriously, uh, being Bugatti, being Manstory, it's got to be close to 2 million. It's really got to be closer to you could even maybe ask more as it's so special.
44:53
Speaker A
So, you think 2 mil? I'd say 2 mil. I really would. I think it's um, mate, try and find another.
45:01
Speaker A
So, what would you say this car could sell for today? Definitely 2 million. It's massive. You might try and ask more, but you know, someone would pay them for it. I don't know.
45:14
Speaker A
Isn't it crazy what's happened in the last 6 months? Well, yeah, but I mean, how long have they been? 450 cars worldwide, 254 16.4s, fastest car in the world.
45:27
Speaker A
So many different things, so many records, so many different things it broke. They've been so undervalued for so long.
45:34
Speaker A
I think 2 million would be I think someone would pay that for him. Yeah.
45:38
Speaker A
Apart from Carl. And Carlo want to pay me. So where do we reckon? What really truthfully would you think it could sell for today? What could it sell for?
45:50
Speaker A
It could sell for 1 and 3/4 million. That's where I think it could sell for.
45:57
Speaker A
And that's being dead realistic. You know, if I wanted to be high hopes, it could be too many quid. Yeah, but I you know me, I'm just I'm as it is.
46:09
Speaker A
And you sell it to guys and I'd sell it. I think it's 1 and 3/4.
46:13
Speaker A
Yeah, that would sell it easy gone. I think it would go easy. Think it would go easy.
46:17
Speaker A
That is crazy numbers. Huge amounts of money and honestly more than I was expecting. But has this gamble paid off?
46:25
Speaker A
There's been a lot of parts bought, man, fake gearboxes, and work trips. It's took a lot of work to get this from a dusty car in the corner to a beautiful shiny spoon piece of art. Well, I'm going to break down now exactly how much
46:40
Speaker A
it cost. But first, it's freshly back from its second polish at the machine shop. It's shinier than ever, and I'm going to finally show this to my extremely supportive family who literally have had my back and trusted my decision throughout all of this. They
46:57
Speaker A
have witnessed the ups and downs daily. And just remember, Jane has not seen this car since the very first day that I picked it up.
47:07
Speaker A
There she is. She looks even worse than before. Like everything in here is beautiful.
47:16
Speaker A
I love that. You're very quiet. I'm just absolutely gobsmacked. Okay, open your eyes. Oh my god, that's nice.
47:45
Speaker A
How beautiful is that? It's got sticky handprints over it from dad. Isn't it ridiculous?
47:58
Speaker A
That is the best thing you've ever bought. I know. I can see my eyes.
48:04
Speaker A
Well done. Yeah. Well done, Furong. I just can't believe it's here and it's on the drive. And everybody was like, "Oh, you've made a big mistake.
48:14
Speaker A
Shouldn't have bought that one. You should have gone for the black one with the orange interior." I prefer that color way.
48:21
Speaker A
I know. I know. Now, now you see it now. It's unbelievable. I can't stop. I just can't stop.
48:28
Speaker A
Well done you. Thank you. And well done you, Ree, for not crying today. Or have you cried?
48:34
Speaker A
No crying. You've actually got a Oh, relax. Come do a family kiss. Just look at it.
48:45
Speaker A
Family kiss. It feels so good. It's actually sat on my driveway. Right, let's now break down how much I have spent to repair and build it. Are we up or are we down? Right, we did it.
49:02
Speaker A
We actually did it. And that massively includes you guys. When you subscribe, YouTube recognizes that and rewards us by pushing us to even more people. And then we get people involved with the Veyron who know stuff about this which
49:18
Speaker A
nobody else in the world would have. So, this is down to you guys. Now, costs.
49:26
Speaker A
Cover your ears. What do you mean cover my ears? I gave you the piece of paper for you, Wally.
49:31
Speaker A
Right. We'll start off with the big one. 6 months ago, we bought this car.
49:37
Speaker A
Seems a long time, but it's actually gone quick. And look, we've done a lot in 6 months. £900,000.
49:43
Speaker A
Finders fee from Ollie and Chris was £5,000. Jamie JRW Motorsport. He has been amazing all the way through this.
49:51
Speaker A
He's never stopped helping us. We paid him because he had to do a little bit of work before we took the car away. £700.
49:57
Speaker A
Big up Jamie. Thank you for being involved to the end. Then we started getting to the big ones. KMP, the legend of Pascal. Howdy. The person who we bought it off had already paid a load of money to get that gearbox to a certain
50:10
Speaker A
place. So, we ended up to cover the rest of the work done after we own the car was £11,400.
50:18
Speaker A
We also bought a lot of very expensive oil off Pascal, which was another £970.
50:25
Speaker A
Work trips to Holland. Some of the places we went didn't offer receipts. Um, feries 600 quid. Hotels £550.
50:35
Speaker A
Fuel £540 quid. Jake from Oport came down and he scanned the car so they could make the adapter for the test rig.
50:43
Speaker A
Jake charges zero pound. Big up sport. Thank you Jake. Big part of our channel and will be in the future. Revotech obviously they did a lot. Made that whole test rig. Spent a lot of time and a lot of effort doing all that and they
50:58
Speaker A
charged us £10,000 which was way under what it should have been. Andrew, our Spanish friend prick with the deposit flight in hotel that cost us £7,693.
51:11
Speaker A
Yeah, but on the back of that Senna and I had a suntan. Had a suntan.
51:15
Speaker A
Then when we were down furongers, Max came down from Hawks Autoworks and he cleaned up obviously the interior of this. Again, wouldn't have a single penny office. So, thank you Max. You will be seeing Max a lot in the future
51:28
Speaker A
on the channel. Bob turned a dull spoon into a shiny spoon. Now, he charged us £1,200, which was a bargain cuz I know how many hours he put into this. So, as an hourly rate, he is a legend. Now,
51:43
Speaker A
food. Basically, a load of meal deals and pepes. Actually, we did have two wagon mamas, didn't we?
51:49
Speaker A
Three. Three wagon. Two. Two wagons. Two wagon mamas. Food was £430. Right. The big bits now. Rob and Andrew.
51:59
Speaker A
Amazing people and if you imagine so so clever they had all that information in their head and somehow they had to make a wiring system to make our car work again.
52:08
Speaker A
They are the Albert Einstein of the Gatis, aren't they? They're unbelievable. Like right there, Bill. Zero.
52:15
Speaker A
They wouldn't have a single penny off. Don't worry, we're going to get them something nice and do great things. But don't let them know that though.
52:23
Speaker A
No, don't tell them. But what absolute legends? They literally will not have a single penny off us. Right. Fur longer bill. Obviously, we use parts, a lot of expensive parts. All of the team, you know, they've had this car for 6 months
52:35
Speaker A
and they've been on it pretty much every day and their bill zero. And they won't have a single penny, which gives me that makes me emotional.
52:46
Speaker A
Like, they've enjoyed the journey. You guys have supported them, and I hope you guys support them in the future. They're an amazing company, like so many other people on here, and like I say, they won't have a single penny off. So thank
52:58
Speaker A
you all of the furonger team. You've been amazing. And this is because of you guys as well. You know, you got to think these are businesses and they need exposure and they need business in the future. And because of you guys watching
53:12
Speaker A
this, millions of you watching it, sharing it, talking about it, showing other Bugatti owners how to do this, these people are going to get lots of business. And that's why they haven't charged us. And that is thanks to each
53:24
Speaker A
and every single one of you guys. Big up. Right. Totals. Okay. Drum roll. Come on.
53:36
Speaker A
9 9 939,083. There we go. Woohoo. So, under40 grand. This car means so much to us, doesn't it? You know, and you guys and all the people on here, it we can't possibly sell this car. So, it's irrelevant what it's worth. Yes,
53:57
Speaker A
they've increased in value, which definitely has helped all of the numbers, but that's not what this car and this project has been about. Big news, you guys can see this car in person on August the 16th at Silverstone
54:11
Speaker A
at tracks. Come say hello to the Veyen Ron um and come and meet us. It would be really good to show you just how amazing all of our team has made this car. This is just the start of this car. We're
54:22
Speaker A
going to be using it. We're going to be enjoying it. And make sure you subscribe so you can come along on the trips as well.
54:27
Speaker A
See you next Tuesday, 6 PM. Well done for not crying, Ree. Good job.

Answers

Frequently Asked Questions

Why is the new clutch slipping despite being brand new?

The new clutch is slipping because it is made from different materials and lacks the original design features like cutouts that help dissipate heat and allow oil flow, causing oil to hydroplane between the clutch plates.

Can the Veyron’s transmission software adapt to the new clutch material?
