To add speed, add lightness.
These wise words are attributed to the legendary English motoring magician, Colin Chapman. For the uninitiated, Chapman founded the famous sports car company, Lotus, and before his death in 1982, led it to seven Constructors' Titles, six Drivers' Championships, a little ol' race in Indianapolis, , and production of many classic sports cars for lucky owners around the world. While his influence and credentials are truly gold standard, it is his engineering theory as noted in the title above that continues to win the hearts of true automotive enthusiasts around the world. And just to make sure we all understood, he also said: "More power makes it fast on the straight, less weight makes it fast everywhere."
