Le Mans Trap Speeds

hello!

does anyone have the top speeds for the 1999, 2000 and 2004 le mans races? i know the qualifying ones are on mulsannescorner, but i could never find the ones attained in the races themselves, to see how they compare.

thank you!

Mulsanne's Corner had both practice/qualifying and the race up to 2003.

Le Mans History has them for individual cars if you look up entries for a particular year, but it's hit and miss:

http://www.lemans-history.com/index2.php

I know that the WEC has them from 2011 onwards, but I don't know of anything other than maybe the Le Mans Annual books that would have that info. I don't even think that the ACO's site or even lemans.org has anything like that on there.

both le mans history and mulsannescorner only have the qualifying ones fr '99-'00. there are some sources claiming a 339 km/h for the toyota gt-one and a 338 km/h for lola in the 1999 race, which sounds plausible, but nothing about the other cars.

Are there any figures out there for the GTS/GT1 cars from 2003-2009? Im intrigued as to what the Saleens/Ferrari 550+575/Corvettes/Astons hit as I believe none of them broke 200mph but apparently the earlier cars came close at around 195mph.

The problem with comparing the speeds is that you are not really comparing like with like. There was a long time when the ACO had the speed trap in the wrong place. But also when you compare speeds from different sources you get different results. Years back I did my own set of apex speeds and peak speeds with Marshall Pruett's kit, I cross referenced my results against those of a LMP1 works team and while the results differed the difference was consistent. So it is about which calibration you trust most.

At Le Mans at the moment the hybrid cars are in lift and coast at the speed trap so we don't see their top speeds.

most of them are not sites, they come from the le mans annuals. from 2011 on, they're from here (unless otherwise noted): http://fiawec.alkamelsystems.com/
some older ones also come from different archived .pdf files from the time of those races.

yes, as far as hybrids go, the speed traps don't tell the whole truth, although over the course of 24 hours, they come somewhat closer to the real speeds than in the practice/quali sessions. anyway, that's why, for the hybrids, i noted the highest speed i've seen on the onboard telemetry, where it was available, if it was higher than the highest trap speed on the aco data.

by the way, when did aco have the speed trap at the wrong place and where was it placed?

sam, do you happen to have any of that data still available (your own measurements from different years and the measurements of the teams that you mention)?

i have got 2005, 2006 and 2007:

2005 gt1 race top speeds:
aston martin dbr9: 302 km/h (both cars)
ferrari 550 maranello (larbre & cirtek): 301 km/h (290 km/h & 289 km/h for the bms ferraris)
corvette: 294 km/h & 290 km/h
ferrari 575 gtc (jmb): 290 km/h

for comparison, the 2005 playstation audi r8 went 318 km/h, the champion ones 310 km/h, the pescarolos 325 km/h.


2006 gt1 race top speeds:
aston martin dbr9: 305 km/h & 301 km/h
aston martin dbr9 (russian age): 305 km/h
corvette (alphand): 305 km/h
ferrari 550 maranello (covers menX & russian age): 304 km/h
corvette (corvette racing): 304 km/h & 300 km/h
ferrari 550 maranello (larbre): 301 km/h
lamborghini murcielago (jloc): 299 km/h
saleen s7-r (acemco): 297 km/h
aston martin dbr9 (bms): 291 km/h

2007 gt1 race top speeds:
saleen s7-r (oreca): 304 km/h & 297 km/h
aston martin dbr9 (larbre): 302 km/h
corvette (alphand): 301 km/h & 297 km/h
aston martin dbr9 (amr): 300 km/h (both cars)
corvette (corvette racing): 299 km/h & 298 km/h
corvette (psi): 298 km/h
aston martin dbr9 (bms): 297 km/h
ferrari 550 maranello (convers menX): 295 km/h

if i remember correctly, the late '90s/early 2000s gt1/gts cars were as fast as you say on the straights. the old vipers used to top at over 310 km/h i think.

2000: http://www.mulsannescorner.com/trap00.html

Mike hasn't posted anything about trap speeds on his site since 2003. All info is what's listed in those years' LM annual.

For some years the speed trap was placed on the approach to Indianapolis, then moved slightly and was located in a braking zone. I don't recall when exactly though.

The data we got I think has been largely lost though there are some articles about it on Mulsannes corner and Racecar Engineering I think

apparently the speeds we have from 1996 up to 1998 are from the approach to indianapolis. also some older, but still post-1990 group c speeds were measured there and some of them are extremely high (i recall 366 km/h for a 962 in 1990, which also hit 354 in the race, also 363 km/h for mercedes c11 in practice).

yes, but those figures on mulsannescorner are all practice speeds. i was referring to the 1999 and 2000 races themselves. i only know 339 km/h for toyota gt-one and 338 km/h for lola in 1999 and some sources claim a 337 km/h for the 2000 audi r8 in the race, before indianapolis.
