Development of the 250 GT SWB Berlinetta was handled by Giotto Bizzarrini, Carlo Chiti, and young Mauro Forghieri, the same team that later produced the 250 GTO. Disc brakes were a first on a Ferrari GT, and the combination of low weight, high power, and well-sorted suspension made it competitive. It was unveiled at the Paris Motor Show in October and quickly began selling and racing. The SWB Berlinetta won Ferrari the GT class of the 1961 Constructor's Championship.
