Sam already published them.
Darn quick too. "How fast, how long and who's quickest. We take a look at the performance of the cars in detail (and find out that the ACO figures are wrong!)" Racecar Engineering / Speed TV.com trap speeds http://www.racecar-engineering.com/a...ner-times.html |

jesus!!!
the peugeot is ridiculously quick through the porsche curves, not surprised by how fast the 908's are down the straights though, intriguing though how slow the pescarolo's are down the straights, seem the pesca's are quite draggy which surprises me somewhat. |

Looking at those times its a real shame the Zytek 07S LMP1 car was not there........its very similar to the P2 car through the corners but considerably faster in a straight line....it could have been very very quick in the right hands.
Perhaps we will see it accross the pond at the end of this year tho hopefully. |

A lot of the info the ACO has posted is incorrect. If you look through some of the qualifying times you'll see errors.

According to french magazine "Auto Hebdo" and their hour to hour race report,the Dome was unofficially clocked at 358 km/h on the Saturdayevening at 20:29.....
That would make it even faster then the lowdrag Toyota GT-One,which was clocked at 351... Allthough the article doesn't state a sourch for their info. |

Re 358kph - its not true. The ACO site reported the same - I clocked a silly speed for a GT2 Ferrari, but anyone with half a brain could see the time was wrong!

O.K.,but just not agreeing with the numbers "because they're sounding silly" isn't good enough for me. Hard evidence is what I wanna see.
Untill then,the number stands for me. Also,I wouldn't be surprised by a high Vmax for the Dome. First of,they've allways shown high straightline speeds,then,their slick aeropackage and the way they followed the diesels and Lola/Aston in the opening hour of the race to me makes it even more feasable. Oh,and ofcourse I just want it to be true. Le Mans cars should achieve higher topspeeds then Bernie's jetset toys imho. |

In my opinion,sportscars are more about formidable accelaration,high speeds and extreme braking. Not about achieving higher and higher corneringspeeds by more and more downforce... |

I've always prefared 3.5l cars over tradtional Group C cars, to me, top speeds have always been secondary to lap times. |

Yup, these were available even before the race started. Now the idea with them (http://www.racecar-engineering.com/a...ner-times.html ) is that, if 358 km/h sounds indeed a bit too much for the Dome, well, these ones seem a bit low to me : I mean, they're clearly true, but they might not be exactly the very fastest of the entire 2008 LM edition.
The reason for me saying this is the fact that the Audi R10 is clocked here only at 335 km/h in qualifying pace, which is slower than last year (339 km/h in the race). And the R10 was clearly faster this year than in 2007 (they did 3:23s and also had faster times on the first sector than last year - which suggests higher top speeds, or at least similar top speeds before braking for the first Mulsanne Chicane). That's why I actually started the thread. In any case, until the next updates, we have 342 km/h for the Peugeot 908 as the highest speed in 2008. Prolly redundant observation: it's the same top speed as the BMW V12 LMR's in 1999 |

And also... the last time times like these were achieved at Le Mans (in the region of 3:20 with the chicanes on the Mulsanne Straight) top speeds were over 350 km/h for the fastest cars (354 km/h for the 905 in 1993, 351 km/h in 1992).

In addition, let's remember that the warmup top speeds were higher than that. The Peugeots did 345 km/h in warmup and the Audi R10 (still?) 336 km/h down the first section of the Mulsanne Straight.
So it's not 342 km/h the highest we know about so far, it's 345 km/h for the Peugeot 908 HDI, until further updates on the topic |

The Dome my have concievably gained 5kph but 358kph is simply not on without a major change in lap times (or sector times). I have asked the guys in Japan to check thier data for that period to put this story to bed. Our times are not 100% as we did not get speeds on every car, but we did get accurate times. Though these were not always the cars fastest laps so each car stated has had at least 5 traps recorded in 1 session to be stated so we can avoid wierd results. This not only gives a clear rsult but also gives you a ball park of what the car is capable of. The Dome was poor in corners due to a TC issue that will not be solved until next month, and that hurts straight line performance. Quote:

The ACO has been shady with the real Vmax's for the last years. There was even a period were they stated not to bring out the trapspeeds anymore!
Le Mans is all about high terminal velocities and should be less about F1 like downforce and corneringspeeds imho. Does anyone know where this stated 358km/h for the Dome originated from? |

and making a slower car, but a car from a country that the ACO is courting for a new series apprear faster ? Noo what the ACO do that? Remember the ACO does things "in the spirit" of the rules, when that spirit favors the a particular team. many of us have been on here a long time to realize that racing is more more then between the Green and Checkered Flags Indpendent speed testing, as Sam has done would be more approprate. |

I can't really understand what happened to the ACO this year that they're so all over the place with the speeds... I mean, how hard is it to watch the radar and then put the number on paper? In any case, thanks Sam for the data so far and the updates! So as far as we know based on reliable data, the highest was still 342 km/h by the Peugeot and 336 km/h by the Audi? |

I wouldn't be suprised if the Pug and Audi went a little quicker (possibly as much as 5kph) in later sessions but those are the bst verified times available. Next year I'm stationing a chap there for all four sessions and test day...
