I don't care about the chassis, its irrevelant.
Just a quick list what we have now:
FWD, RWD, 4WD. I think that fully covers all cars IRL

We have mid engined car, rear engined and front engined too. Same as the first

About the engine types. Inline4 , Flat4, Flat6, Motorcycle engine, F1 engine.
I like to see:
- rotary engined car
- diesel powered car (I dont like them, but it would interesting to race them against the petrol ones)
- american big V8 muscle car, with oldschool suspension, and brakes
- racetruck
- karts
something new ...
