I really like endurance-racing,
or what about team-racing, where you have to drive on turns (your teammate's car gets in, yours leaves, leaves you the time to switch battery, ...)
With such races it also about consistency and proper preparation. I have often seen that the winners where not those who made the fastest lap.
some other idea (yeah, I played Trackmania too often) why not build in a looping, even for Touring
