With the way race cars suck down fuel, and all the science behind their aerodynamics weight isn't an advantage at all. Robbie's just a whiner.

Yeah, right. Laws of Physics be damned. Weight doesn't matter -- that's why teams build cars out of cast iron and depleted uranium.

Actually, weight is extremely important. The air effects create a downforce at speed, allowing the car to be lighter. Light weight is what's important when in comse to accelleration and braking.

While I don't know what the ratio is in the case of 4 wheelers, but when it comes to motorcycles, every 5 pounds of weight eliminated is roughly equal to increasing engine power by 1 HP. So, if I were to go motorcycle racing at 200#, and my buddy Shane only weighs 150, when it comes to accelleration, if we were on the same bike, he would have roughly the same advantage as an additional 10 HP. And braking is quite a bit easier on lighter bikes as well.
