Hah good point! I am in the same boat, but FYI it is Cars 2 you're thinking of, in which Sir Miles Axlerod promotes Allinoil biofuel by running it in the World Grand Prix but colludes to blow up the race cars to give the alternative fuel a bad reputation. Cars 3 is when Carmen the trainer becomes Lightning McQueen's racing protege. (edited: sp)
