If you have any new car, chances are that if you slam on the brakes, it
will lock up all four wheels. Any increase in this braking power (often something like 600-700hp on even mundane cars) will not increase effective braking at all. Ever notice that braking distances between supercars and 'normal' cars are almost identical? Usually between 100 and 120ft. The
improvement in braking systems comes not from decreased stopping distances (more to do with tires than actual brakes) but the
repeatability of maximum or near-maximum braking. That is why carbon brakes are used on race cars, they simply do not fade.
Anyone else notice the 5th car in the shot? Just behind the Subaru. It's really impossible to tell, but for some reason I'm thinking Dodge Viper GTS:
