SNES had a lot of very cool racing games - other than Top Gear and Nigel Mansell series - that never got much attention. Exhaust Heat, for example. You start a F1 team with a very simple car, and make money on races. With the prize's money you could buy new car parts - engines, chassis, aeros, tires and suspensions! I remember the game was not FIA licenced, so the engines names reminds only Judd, Ford, Ilmor, Renault, Ferrari and Honda.
Exhaust Heat 2 did not have this cool tuning part (it had a R&D department, but was not the same), but it was not only F1 any more. You start your career as a Group C driver (but, it has only Saubers C9, on several colors...
)
Once you won Group C, you go to F-3000!!! And, after that, F1. But, the 3 first teams was Benetton, Footwork and Larousse. If you did well, you could go for the next 3 teams, McLaren, Ferrari and Williams. And this time, it was a FIA licenced game, so the teams and circuits had their real names.
The graphics on the second game was a lot better, but the tracks looks like F-Zero tracks, it was really weird!
