I recently got a subscription to Road and Track and have been glancing at all their stats on different cars. It seems the average 60mph-0 braking distance of a regular ole sedan is around 120 feet.

In the back of the manual for my 1985 300D it says the car should stop from this speed at around 165 feet. Just an interesting tidbit, i looked up the stats on the Honda CRX from the same year, it has about half the weight as a w123 and the same brake distance. So i assume these four disc brake systems were quite good for the time, but what advancements in brakes have been made in 20 years to lose 40 feet from a 60-0 stop?
