Prima facie it's a kind of easy track...
IMSA type cars will drop out early.
Maybe Lotus? Countach? Corvette? An insane GTO powergear rampage?
Calculating with (a bit optimistic? :D) 1:15 as winning time:
1:47.15 - LM002
1:42.75 - Lotus
1:41.35 - Trueno
1:41.35 - Countach (compared to Lotus: slightly better accelaration, a lot higher "non-official" top speed, slightly slower in corners)
1:34.95 - Corvette
1:30.35 - Lancia
1:30.35 - Audi Quattro
1:28.25 - Acura
1:27.20 - Ferrari GTO
1:27.20 - Carrera
1:14.25 - Mercedes DTM
1:14.25 - BMW DTM
1:14.25 - Melange
1:12.10 - P962
1:06.95 - Jaguar
58.60 - Indy
Although this track is 100% paved, it's worth to remember the special ability of Lotus Esprit Turbo.
Usual car grip values: 100% on asphalt, 75% on dirt, 25% on ice, 50% on grass.
Lotus: "100%" on asphalt, ~148% on dirt, ~49% on ice, ~98% on grass.
Turbo Zone corners... :)
Although powergear is not my cup of tea, it would be great to have at least one competitive PG car on this track.
