Top Speeds: Le Mans
Last year in the race, the Pesca hit 324kph top speed--according to the ACO.
I think the Pesca will be quicker this year but the Audi will havethe capacity sto slaughter all and sundry. My guess for this year: Quali: Audi 340 kph Race: Audi 330 kph The Dome will also be quick but the torque of the diesel and, for qualification, the capacity to 'fuel up' to prodigious bhp will put the Audi on top of the totem pole in terms of top speed. |

Intersting topic. The R8 was not usually at the top of the heap in terms of top speed. They preferred to let the overall lap-time do the talking, which of course is the most important number.
I'd say the Dome will still be quick in a straight line. Perhaps Pescarolo will be up there to. But I'm quite intrigued to see how the R10 will stack up to the R8 in terms of speed and of course lap-time. Wish they hadn't altered the circuit this year so some real comparisons could be made. |

I think that the R10 will have a decent straight line speed. That engine can push it through the air quite well I beleive. |

Take 2002, the year the R8 had pole with a 3:29.905. They were mid 320kph in comparison to the Dome, Bentley, and Courage C60, which were mid 330kph.

Thanks for the link reminder.
It is a bit of both, I feel. What I like best is the relative differences of the cars between practice and the race. The R8 was always more 'competitive' top speed wise in the race. |

Because of the aerodynamic restrictions, the top speeds should not exceed 325 km/h. The R10 will make the most of their acceleration capacity.

I think the drag figures are less than 10% higher for new LMP1s... and the R8 was a 2000 chassis much bigger (frontal area-wise) than the more sculpted R10. And lift-to-drag has progressed a lot: all LMP1s are producing more downforce (a sensible increase) on a more stable (easier to exploit) aero platform. And engine power has gone up more than 100 horses compared to last year's restricted but still capable of 320+ kph.The Lola has a few hundred pounds more downforce (than the Dyson B01-60) for a drag increase closer to 5% than to 10% I think.
So I think the top speed are gonna be in high 330s for balanced cars like the Audi and could be surprisingly close to 350 for cars like the Dome or maybe the new Courage... What was Pescarolo's top speed last year? I'd guess in the mid 330s... with a wing that was replaced at the very next race (not fully developped at last year's race) And the efficiency gain of an R10 is gonna see the cars under the 3:30 barrier I guess...

the pescarolo only got 324kmph which is about 200/201 mph which is frankly rubbish for a LMP1 car but on the DVD it said that in practice the pescarolo got 218mph in practice so maybe this year the hybrid cars will be faster than last year maybe, dome's i dont think are quite as fast as they were in their previous LMP900 form but i think that the fastest car in a straight line will be the swiss spirit courage or the creation CA06H for sure at around 210mph maybe even 215mph

Teams may well go in the opposite direction, increased power may encourage them to run increased downforce levels for a quicker, more comfortable lap.

The new GV5 may have a bit more but only maginal from a top speed perspective (maybe 1 kph) I just noticed that the cars are running a small Gurney as part of the regs. That will reduce top speed by a lot. Was the Gurney mandatory last year? If so, I will have to lower my own estimates by roughly 5 clicks. |

It's a clever way to cap top speeds at this unique circuit while having little effect, if any, on regular, slower, higher downforce tracks. |

I dont agree with that at all . The drivers are always screaming out for more power , and i feel that as they are the ones in the seat , they should get to make that call .
A certain Mr.Wallace is always looking for more power . |

Point is, top speeds at Le Mans, which is a pretty unique track, need to be kept in check. Rather than cutting power or drastically changing the cars, it makes more sense to add little aero devices such as Gruneys to keep top speeds in check. Better still, they have little effect on high downforce tracks were speeds are not an issue. |

It will be very interesting to see the top speed of the R10.
While they may give more downforce in the set-up, we may be able to get a good idea on how much power the car has. Theoretically, they could have 700 plus bhp--giving another 10 kph on the straght than any other car. |

Is there a different restrictor size this year ?

The thing with the restrictors is that the older cars ran smaller ones than the newer cars are allowed.
BTW, would that LC2 in your forum alias be in reference to the Lancia LC2 Group C car? |

In the LMS and Le Mans, Hybrids (older converted cars--Zytek, Pesca, Creation) have the same restrictor size as the new cars. |

The new areo package, without the Gurney, makes the cars much less likely to lift off than the old GT1s (Mercedes CLR, Porsche 911 GT1-98). The new prototypes are much less attitude sensitive.

Lets not forget that the hump that was on the Mulsanne where the Mercedes CLR took off on has now been lowered by 1.5 metres. I forget what year exactly this happened on but I think the change was made in time for the 2003 race.

............and the R8 is from the same era rules as the CLR/GT-ONE/V12 LMR etc. The R10 is the first Audi built to the new regs. |
