you are skillful at drawing.
designs were ok.
I couldnt understand what ur asking about this mercedes wheel base?
wheel base is designed for purpose, not to look good.
front wheels , if placed as close to the front end of the car as possible will give very good steering response.
rear wheels placed as close to the center of mass of the car as possible would give maximum grip on the rear wheels.
rear wheels placed as close as possible to the rear end would give better handling since there would be little counterweight behind the wheels to make the rear end skid outwards on corners.
To give the car the ultimate balance(on rear wheel drive cars), rear wheels are placed mid way between center of gravity and rear end of the car.
Couldnt understand what levin is saying....
try designing a common man's car.
