each car handles differently and responds to the e-brake and Reverse differently. The Quadra Type-66 "Javelina" will feel like you are drifting constantly. it can slide over bumps without issue
The Quadra Turbo-R V-Tech and Caliburn, are from another planet
there is a connection between frame rate and vehicle speed. if you are blow 30 fps you will be slower than if you were at or above 60fps. In older versions of the game frame rate also influenced physics. more FPS = higher jump. so i wouldnt be surprised if system instability or alt tabing fullscreen mode messing up your frame rate might do something unexpected.
