Veyron slower than expected?
Discussion
Having recently see the video from EVOmax https://www.youtube.com/watch?v=lF2x3svjPjk&li... i thought the Veyron would be quite a bit faster than it was given it does a standing mile in 204mph and the Aventador does 189mph over the same distance.
Looking at those numbers i would have thought it's 207 at Bruntingthorpe compared with the Lambo's 204 seems a bit off. Anyone who attended know what the deal is?

It could be the gearing, up to 200 it's optimised but from there to top speed is a long haul in the available gears.
Im not sure it is gearing or some other disadvantage at slow speeds. The bug's 0 to 60 time is quicker than the lambo and it's 0-300 time is about 5 seconds quicker.The race against the F1 in dubai is a bit of a puzzle too.
The issue for the Veyron at Bruntingthorpe was the low drag setting. Unfortunately every time he took the first corner it cancelled and the wing popped up, adding a load of drag once on the runway. You really need to leave the corner at about 80 to get a good speed by the beam, so he couldn't get the right setup for the location.
To help compare the LaFerrari with the Veyron they ended up doing a standing start on the runway, which didn't allow either to get to their 207 max for the day, but did allow them to be compared off the line.
Hope that helps,

Ah i see. That makes sense. Thanks for the response.To help compare the LaFerrari with the Veyron they ended up doing a standing start on the runway, which didn't allow either to get to their 207 max for the day, but did allow them to be compared off the line.

This assertion that "You really need to leave the corner at about 80 to get a good speed by the beam" sounds completely credible doesn't it ? - it isn't.To help compare the LaFerrari with the Veyron they ended up doing a standing start on the runway, which didn't allow either to get to their 207 max for the day, but did allow them to be compared off the line.

Me and some fellow Brunters aficionados have spent quite a lot of time messing around trying various ways to increase top end at Brunters. Believe it or not the speed through the beams is more or less the same whether you come round that corner at 80 or whether you start from a standing start at the beginning of the main runway.
The reason for this is if you do a standing start at the beginning of the main runway you will be doing between 60 to 80mph by the time you are level with the exit of the (80mph or whatever) bend and more importantly you eventual top speed will not change by more than ~1mph if you are doing 60 or 80mph at the exit bend point.....
The reason is that the distance needed to reach 60 or 80 is very small compared to the distances needed to put on speed above say 300kph/186mph.
It takes the Veyron about 575 metres to go from 186mph to 207mph at Brunters, this is where the hp (and drag) are most in show.
Here is the stat which really puts in in perspective: To go from 205mph to 206mph takes only 0.85s but needs 75 metres of runway.

Saved me a post as was going to say the exact same. This whole getting the entry to the straight spot on a carrying an extra couple of mph really makes little or no difference by the time you're hitting the timing beams.Me and some fellow Brunters aficionados have spent quite a lot of time messing around trying various ways to increase top end at Brunters.

My favourite was with Rob (DMS) when he 1st got his E60 M5 & naturally tuned it. At the time i had a Sported tuned C5 RS6 & no matter what we did we could not get any daylight between the 2 cars either on the start line launch or the speeds through the timing beams. In the end we tried a couple starting from the bottom of the main runway & we could see a few slight differences in performance at various points through the run (only very slight), but still the exact same speed though the beams, although we were 1-2mph slower than when starting from the regular start line.

However, that isn't really the point. The reason the Veyron didn't go any quicker on the day was because the low downforce setting kept cancelling out during it's fastest runs (which happened to be when it used the corner).
I'm pretty sure the Veyron would have got a faster terminal speed than the LaFerrari if the beam was moved further down the runway (and the brakes would stop it before it hit the 747)
Toby is spot on here, it makes really no diff whether you carry speed through the bottom bend or start from the park area in the bend. Over the years I have tested there endlessly in 700-1.500bhp 911's, you will see 1-2 mph delta that's it. Only in lower powered cars ie up to 500/600'ish bhp cars it will give you an advantage carrying speed round the bend. The bigger power cars build speed so quickly that low speed accel requires very little distance.
Would have been surprised if the Veyron would have been quicker, shifts slower and loose significantly on power to weight. Actually I was a little surprised the LaF didn't build bigger distance on 0-300 kph. Eventually the Veyon will reach a higher Vmax since they are not geared for same purpose.

Great to hear someone that knows Topspeed running at Brunters. Been gathering data for 13 years. If a fast accelerating car is slower from a standing start they need to sort out there launch skills because it should be going faster than a car coming around the bend like an out of control jelly as I see watching Vmax videos. If you use the bend to save transmission stress its slow in & use all the width of the road that way you can get straight & 100% on the throttle quicker & at a higher speed.Me and some fellow Brunters aficionados have spent quite a lot of time messing around trying various ways to increase top end at Brunters.

Heres a guy who knows how . 187mph before brow of the hill on a test run.

I do wonder how the veyron had different results racing two different laferraris at vmax?
Both races have clean starts but the laf pulls on the bug in one and the opposite happens in another. I've watched them a few times and there doesn't seem to be no obvious reason why the results are very different.

Veyron did 224 from a standing at on Sat in the wet.
Saw that, wonder if it was a souped up Bug or a Bug SS... Done a few roll ons with standard Bugs and they are not that quick, I comfortably manage them in my lowest power setting doing 50-350kph. At lowest power settings I do 218/220 on Brunts. That's stopping in time to make the right hander which we have to on weekdays.Anyway... Looks like Craig and AutoVivendi team again put up a great fun and safe day.

It's the low and high downforce modes . In the video where the ferrari beats it the veyron is in high downforce / drag mode Both races have clean starts but the laf pulls on the bug in one and the opposite happens in another.

Not people people say that lol ESP as every hyper car and tuned car were at Vmax this event and the bug was still fastest..
I was happy to do 211 mph in 918, was a very impressive thing.
Hi 911V,
Craig mentions that bug ran with all spoilers retracted and even all the brake ducting under the car closed.
The driver obviously new what he was doing so add in some 'top grade' fuel.
Not sure if they could turn the Turbos up as data is constantly relayed to the factory.
Mark.
Oh and the 918 did 204 mph through the traps.
