The lap times don't seem to be very accurate. How can the 911 turbo be only 0.8 sec faster than the 350z? And same exact lap time for the e46 M3 and the Z? No way...

 

Wet track.

Here is a link to a list with more track conditions mentioned:

Any real big dog car you see on that list beneath or slightly above the 370z in times were run a very wet track. You know what a GT3, 911 TT, Viper would do to a 370z on a dry track so you know somethings up with them all registering near the 370z time. 370z is seriously quick regardless. I knew it would beat the Evo 10 as the old "RevUp" 350z did the same to the Evo 9 on our shores. Wish it was closer to the Cayman S. Thats the old Cayman S too I believe yikes.

 

Ahh.. that explains it. So the 350z is on par with the e46 m3? Yay! Hhaha

 

that was a DE 350z BTW.

 

idk where i heard this but i heard that at one point they changed the track length a little, not sure if thats true or not, anyone know?

 

There is a wiki article on the history of the Top Gear Track but it doen't mention any changes to the track itself, just that weather conditions vary a bit, when they changed cars for the "Reasonably Priced Car" routine, etc.
