In the article it says "Colin Chapman, founder of Lotus Cars, was famous for saying, "To go faster, just add lightness". Chapman was renowned for finding innovative ways to reduce the weight of his race cars."
Teddy Petter (British aeroplane designer) is usually credited with having said:
"Simplicate and add lightness!"
If only Chapman had followed both parts of Petter's motto I feel sure his Lotus designs would have been even better (and perhaps a tad more robust).
