yep
Nascar
Japan GT
Audi R8
3 Car class levels ( Instead the 9 car class we have now.)
All 3 classes had 5,10,20 min races
The 20 mins race have allready been on different tracks.
Nascar - 20 min was Daytona ( slip streaming of the Nascar still decides the winner just like now.)
Audi R8 - 20 mins was trial moutain ( and yes the W12 was just as over powered then as it is now. )
Japan GT - 20 min was Susuka ( Yes this race was still just a Nissan Vs Honda battle. )
