Suggestions from the top of my head

Thease are just suggestions/questions from the top of my head, I do not know if some of it is already planned, but just remove the post if you feel it's inapropriate.
Multi aspiration, Like the new Jaguar CX75 prototype having 1 supercharger and 1 turbocharger (i think)
Hybrid cars, having like a petrol/gasoline engine powering rear wheels and 1/2 electric engines powering front wheels.
Big "trucks" like the Ford F350/450 etc.
semi trucks/busses?
"clean fuels" (Completelly forgot what it's called) like E85 (85% ethanol, 15% petrol/gasoline), pure ethanol, biogas (i know some swedish busses run on it, i have no idea if it whould work in cars) etc...
Making it so that in the model designer, if you raise the hood/bonnet or pull the window backwards, you will be able to fit a longer/higher engine in the car. (Probably allready planned)
I will update the list once every few days, removing and adding new stuff, if it's ok to post like this that is.
