This has beaten the previous record (I think it was record) of Hockenheim 1996, where Mika Hakkinen during the race got to 345.6 Km/h. > what is the time on quart miles for a f1 ? I posted the following one year ago (Date: Aug 15 22:03:30 1996) (and this time I will include it in my homepage). -=-=- This should be in the FAQ since the question appears so often. This was posted a long time ago (I added km/h, m/s and m/s^2 to the table): Newsgroups: rec.autos.sport.f1,rec.motorcycles.racing From: ian@btcase.bt.co.uk (Speed Freak) Subject: Williams acceleration data (was Re: Performance of F1 cars...)

This old data would seem to substantiate that claim. Here is real data from Williams on-board equipment. It comes from a 1992 FW14. I know this is not current but nobody else seems to have come up with any hard facts. This is reproduced from a Fast Car article in Jan 1993. As the Williams spokesman said, this is very dependent on wing angles, gearing and atmospheric conditions. Williams would not even reveal where this data was recorded. Who knows if it represents the best that that car could attain ? mph sec km/h m/s m/s^2 m/s^2 (last period) 0-10 0.32 16.09 4.47 13.97 13.97 0-20 0.73 32.19 8.94 12.25 10.90 0-30 1.11 48.28 13.41 12.08 11.76 0-40 1.48 64.37 17.88 12.08 12.08 0-50 1.86 80.47 22.35 12.02 11.76 0-60 2.18 96.56 26.82 12.30 13.97 0-70 2.50 112.65 31.29 12.52 13.97 0-80 2.86 128.75 35.76 12.50 12.42 0-90 3.22 144.84 40.23 12.49 12.42 0-100 3.59 160.93 44.70 12.45 12.08 <- until this point the instantaneous 0-110 4.15 177.03 49.17 11.85 7.98 acceleration is greater than 1G 0-120 4.62 193.12 53.64 11.61 9.51 0-130 5.36 209.21 58.12 10.84 6.04 0-140 6.03 225.30 62.59 10.38 6.67 <- until this point the average 0-150 7.07 241.40 67.06 9.48 4.30 acceleration is greater than 1G 0-160 8.12 257.50 71.53 8.81 4.26 0-170 9.80 273.59 76.00 7.75 2.66 0-180 13.2 289.68 80.47 6.10 1.31 The 3.5 litre engine produced "in excess of 700BHP".

If he flew them he was crazy and didn't have to; but if he didn't want to he was sane and had to." -- Joseph Heller ---- Note that these days the 3.0 litre should be above (there is talk about 780 HP for the Renault, maybe 800 HP for the Peugeot) the power of the almost 4-year old 3.5 litre and the cars do not weigth more. I am not sure about aerodynamic drag. But, as everybody in this newsgroup knows by now top speed at Hockenheim was 345.6 Km/h (Mika Hakkinen during the race), which is 214.7 mph. I think we can conclude that the setup used in the test reported above had more downforce than the Hockenheim setup. -- http://www.mat.uc.pt/~rps/f1/ an ex-tifoso since 95/11/13 .pt is Portugal| `Whom the gods love die young'-Menander (342-292 BC) Europe | Villeneuve 50-82, Toivonen 56-86, Senna 60-94
