Try TrackMania: Sunrise if you want cars that can go really fast pretty quickly. Though, you don't actually race anyone and there isn't collision detection between cars, you actually are beating the clock. (That is actually a GOOD thing seeing as you make a lot of crazy AND I MEAN CRAZY jumps and stunts.) Luckily, there are three (soon to be five) other more gametypes including platform, puzzle (you build tracks in puzzle), and crazy (the name is true), and soon to be stunt and extreme race. You can really feel the speed if you happen to have a good enough computer to use the motion blur. The motion blur is very excessive, it gives me the feeling that I was driving impossibly fast, but it cut my framerate in thirds. The best part is that you can create your own tracks with it provided that you earn coppers to build them. You earn coppers by doing well on the road, and you can use up to your total amount of coppers when you build tracks.
Btw, your car can get up to 400kph+ on its own with a straight track. This goes MUCH higher when you are going downhill and when on speed strips and super speed strips.
But, if you aren't interested, I don't know where (if you could) you would find exactly what you are looking for.
