An epic supercar battle raged in the late 1980s between the Ferrari F40 and Porsche 959. With analog rawness, the F40 competed against the computerized 959 on the road, track, and in games like The Duel: Test Drive II. The Ferrari was considered more performance-oriented than the Porsche. However, that equation changed with the 959 Sport.
Recently Henry Catchpole had an opportunity to drive a Porsche 959 Sport for an episode of The Driver's Seat. Known as F9, it's one of the first prototypes of the 959 and arguably one of the fastest 959s ever built. Most 959 Sports are about 100 kilograms, or about 220 pounds lighter than the 959 Comforts, but F9 is speculated to be 200 kg lighter, the equivalent of 440 pounds.
