Fastest part of the Le Mans circuit
I am pretty sure that most of the teams now think that the fastest part of the chicaned circuit is the run down to Indianapolis. Is this correct.
Now I also think that most of the speed trap figures are by the Restraunt on the first part of the Mulsanne Straight this is the fastest part of the three sections on the N138 I think, but why don't they measure the speeds before braking for the Indianapolis sequence? Tradition? Also does anyone have any ideas what the difference in speed is at these two points? I would imagine that it isn't that much difference as most cars are nearing their terminal velocity. A couple of mph tops? FWIW I read the Dome hit 207mph. I think there is a thread round here somewhere with this info! Not that top speed is that important, but what do you think the actual top speed is over the Le Mans weekend? Any clues as to what the odd slipstreaming move might have added too? And finally, is there anywhere else on other circuits that these cars race on that may rival these speeds? My guess is no. |

The straight before Indianapolis was the fastest part of the track in the middle of the 90' but, don't ask me why, I don't know, if I can remember what said Jan Lammers in an ACO's annual, the fastest part of the track was in the first part of the Hunaudières again...
The Dome (the fastest one), reached 340 km/h here those last years. Before Indianapolis, it could be 10 or 20 km/h slower... :confused: I don't think they could go faster than 330 km/h now, and the purpose is to win some time in the curves or slower part of the track ; the price to pay for a real top speed is too high regarding the rest of the track. But some cars are still too slow for their category (Courage Evo, WRs) when some others are really fast and hard to take over (575)... This one was taken during the last 1000 kms of Le Mans (Jérôme Mugnier's site). Last edited by Fab; 14 Dec 2003 at 06:54. |

The track between Mulsanne and Indianapolis has two curves, it's not very wide and its surface is not enough even to allow high speed. I mean it makes taking off easier...
The Hunaudières straight had been improved in april 1988 with modern methods (laser measurements, coating...). It allowed the WM's 405km/h and the surface looks like a "billiard". In 1990, the Nissan n°23 reached 366km/h near the restaurant (with 1000hp at that time). These could be some reasons why the top speeds are still reached in the first part of the Hunaudières.

Well, i'd say the highest speed is at Indianapolis for two reasons
1) The first part of Hunaudieres is uphill 2) The Indianapolis section is downhill, plus, they don't have to brake so late at the other end. |

Does anyone know whether the cars run flat out now? I get the feeling that as well as being tuned down for the big race that very few of the cars are being pushed to the limits as they used to be.
Also didn't really get the impression of speed this year as much as before - LM getting too user friendly? |

It was without a doubt bloody fast, but was it at the limit?
My point was that i'm not sure that the cars are being pushed as hard as they once would have been. I must confess this year i travelled the least ever around the circuit. Spent most of the time at the Ford chicane in a g.stand, so not the fastest part of the circuit by a long stretch. The speed through the new section after the Dunlop was amazing at night, but again were the cars (esp the fastest cars) on the limit? Perhaps i could point to the improved endurance of the top cars by way of example, though i take on board the "bullet-proof" nature of some of the teams now. |

The Audi engine of course runs a far lowers revs than say the V12 of the BMW's that one previously and the screamer Judd and Ferraris of recent years so they never sound like they are running flat out. But if you travelled out to Arnage last year and watched the way the Bentleys to Indianapolis and Arnage it was simply awesome. I think I have never seen cars look so fast through that section.

Having Driven a 1959 Birdcage Masserati round the track this June i would say scariest place is down to Indianapolis
fairly hairy at 160 plus mph.next toughest would have to be exiting porsche curves without any grip. |

I can't comment directly, as I have not had the privelage of being at Le Man's in person. But I think I can comment in general. These are racers. Bentley certainly were not quick enough to back off and coast and still beat the Audi teams. And the Audis new they had to give the highest effort to defeat Bentley. The drivers and teams want to win and will certainly push as hard as they can to win the race. With reference to what AMT said, they can't totally sacrifice reliability, but I think they push to the limit with that factor in mind. Now I can speak directly to the ALMS cars. Those guys are pushing hard to the limit. Did you watch Lehto driving his rear end off the last few races trying to get that drivers title? Or the Corvette/Ferrari battles? Great stuff!

And the lap record is curently done in the second part of the race (less cars on the track), except when the weather doesn't allow it. |

I still mourn the loss of the run from Dunlop to the Esses.

Ayse, we still dodged the worst for now (a brand new track, sid of the historical Hunaudières)...
I'm more shocked by the vanishing of the trees at La Chapelle... Last edited by Fab; 18 Dec 2003 at 06:07. |

I guess there's not much we can do about any of it. I'd love to have the circuit back to how it was when I first went in 1986, but.......
