Thanks for the track info
I completely understand the point of view RC45, the ZR-1 as a 375bhp vehicle in 1990 managing 280kph for 24 hours is a truly impressive feat. I'm not trying to sell it short, nor the more recent attempts at the record. The only thing I was trying to do was explain that the faster the cars go, the more they have to put up with, so in order to achieve something like 322kph for any extended period of time at Nardo, the car has to be able to maintain that sort of speed for lap after lap around a circular track which inherently scrubs speed off. In essence, the cars are running laps while understeering (or occasionally oversteering) nearly the whole way. If the ZR-1 was run at Nardo, no doubt it would still hit nearly 95% of its top speed, while the exotics would be significantly farther off that mark even if they did run 42kph faster than the Vette.
I guess what I'm trying to say is that the track limits the possibilities enough that eventually it isn't really feasible to go any faster in any car. Until some enormous breakthroughs in Aerodynamics and tyre technology come up, it's unlikely we'll see anything much faster than 350 at Nardo.
Does anybody know where the 322kph number came from, all I can find is 7085.7km in 24 hours...which comes to 295.24kph on average.
Oh yes, and if you want a really stark comparison which shows how much tech has changed, look at the records for the bowl at MIRA in Britain:
"With a lap time of 1min 00.56 secs, the F1 comfortably exceeded the previous record of 161.655mph (260.15 km/h) set in April 1967 by the Jaguar XJ13 sports-racing prototype. The XJ13 — built with the express purpose of winning the Le Mans 24-hour endurance race — was driven by David Hobbs."
In other words, that lap by the Macca was run at a little over 168mph...
The VW Nardo looks a little more impressive now doesn't it, LOL hehehe.
