# Reach concrete, numerical values for certain car values, in a car game

I am developing a rather complicated racing car management browser game, but I think this applies to any car game.

I have 10 values. Power, acceleration, etc. that can be easily quantified by using available data (hp, 1-100 kmh time). All is well, but I have 4 values (Handling, Braking, Transmission, Front/Back-Weight) that I'm not sure how to quantify.

Would I just say X car has Y brakes were Y = 20 (arbitrarily decided because I think this car brakes Y well) and then put it in a formula with car power and weight to reach this value, or does anyone have a better solution?

• How accurate is your physics model? Do you use a realistic engine 'torque curve' or do you just use a basic 0-100km/h type setup. If you use 100km/h times, perhaps you could use something like the 100km/h-0 brake times that are posted for various cars. Let me know how accurate you want the physics, and I'll try to help you out.
