AMS chief editor Bernd Ostmann has been the first mag tester that had the pleasure to ride 400+ in the EB 16.4 Bugatti Veyron at VW test course Ehra-Lessien...

some impressions what he said about that day...

the track has been kinda damp in the morning, kinda scary at 400km/h, so 111m/sec without crash barries like in Nardo, well not really, rear wing setup to 2° so 40 to 50kg downforce at rear axle engineers promise that this´ll be enough for a smooth ride even on wet pavement...
through the first corner with 220 easily - absolute brutal accelerating up to 300 within seconds a light left hand bend with 380 - looking into the rear mirror - just an enormous spray but just like they told the EB16.4 is a very smooth car to ride even at that speeds...
the sepcial Michelin tires are working just perfect, they were tested up to 500km/h and before a high speed run they require 3bar pressure - this is one of the points the driver has to go through with a check list and a second car key to unlock the high speed mode - here the two front diffusor flaps are closed, the rear wing selects 2° and the body is lowered to 6.5cm front and 7cm rear a sepecial system is monitoring everything and when only one parameter is not ok the car automatically switches to handling-mode...
the first run ended with "only" 380km/h - the car switched to handling because the exhaust temperatures reached critical 970°C - cooling down the car at 220 or 5000rpm in 4th gear...
the weather gets better, it´s much warmer now and engineers force the AMS team to "act" - next run 398km/h - this time it´s the driver´s fault as he has enabled the A/C on the previous cooling lap costing some km/h on that fast run - so again a cooling lap and then full concentration on the last run with nearly 400 the rpm showed 5800 in 7th gear, now it shows 6200rpm at a speed of 402km/h ...

braking is again a new experience 31.4m (!!!) from 100 to 0 with a 1950kg car...

on the other hand acceleration is also outstanding - measured 25m long black rubber from all four wheels after the standard sprint with launch-control - result: 2.5sec to 100 and 7.3 to 200 :shock:

on a side note - at 400 km/h the EB16.4 needs ONE liter fuel for ONE kilometer so they calculated every 12min a gas station on autobahn when driving 400 :wink:


haven´t seen anything yet but i think there´ll be a special on AMS-TV in one of the following shows, be sure it´ll be posted here asap... :)

Thanks St-Anger!! Great article.

WOW 2.5 sec to 100? I didnt even think that was possible................damn it out accelerates a bike

:shock: OMG is this real?

Oh - 0-100kmh... 2.5 is still a full second slower than bikes :P ;)

Was that 1l/km? :lol: They get tops speed, top accelartion, top stoping and top fuel consumption.. Not bad ;)

Now - can it turn...??? :?: :?:

jesus christ! that is some crazy figures...

thanks st anger!

So - same laws of physics. Power/weight/gearing/tractive effort. ;)

Which leads to me original thought - let's see it turn a corner.. :)

So bascially the time it take me to say "What the fuck?" in a normal rate, the car already accelerate to 100km/h..... :shock: :shock:

1L/km @ 0.111km/s translate to 9L/s ......... I would like to see the fuel injectors @ work lol

...straight line for sure 8) ....when it get´s a bit more "interesting" so e.g. on a track like nordschleife......."no thank u..." :wink:

The Veyron figures are incredible ! :shock:

Thanks Herr St-Anger for this AMS scan. :D

Holy Shit!!!

Thx a bunch for these scans St-Anger !!!

I was about to go to bed, but now I'll read it at once!

I can't wait to see the vid :twisted:

Thanks St-Anger! those are some insane acceleration and braking figures :shock: seriously, for a car that weighs that must those brakes must be of other-worldly materials to stop it that fast!

also, does anyone know what Michelin used to test the tires to 500km/hr?

We know it wasn't the US GP.. :P

1L/KM.... 9L/s... and say a 100L tank.. that means you are out of gas in 12s?

Where have we gone wrong with our math? ;)

A Dynomometer and simple Physics :wink:

It can't be 9L/s cos the fuel rings in F1 do 12.1L/s. :shock:

In fact it is 0.111L/s
0.111/s x 60s = 6.66L/m
6.66L/m x 12m = 79.92L

I think this is the correct figure 0.111/sec :D

Still that should be a problem for the people in UAE.
