Thanks for checking it out! Most of the cars should be closely related to real world cars, although they are not exact for a reason. The discrepancy you point out is probably the car called 'Asphalt' which is one of the few cars that isn't based on real world data. I built that car as an example of a drift car. I plan to categorize cars once I nail down the format for a campaign/career mode. I do appreciate the feedback and if you feel any other cars misrepresent what you might expect feel free to point it out.
