Before you start complaining: Yes, I read you’re not planning drivable cars, so this is not about that.
But, in this old car game (Where you could draw a car layout in 2D) there was an option to do an automated test through a pre-generated test track.
The test track had a long straight, fast turns, slow turns, a weaving section - everything to test the vehicle.
The end result was a tested time, and you could also include data about each section, as well as top speed and everything.
Now, that game had a pretty decent wind/drag simulation, so that may not be easy, but you should think about lift/drag, breaking, steering, total weight and obviously the engine.
But, as everything is automated, you don’t have to worry about how the car ‘handles’, and you could even come away with a 2D topdown simulation to show where it is - the visualization don’t need to be realistic, but the results should.
