F1 wizard Gordon Murray reinterpreted the 2J's innovation for one race in the 1978 season with the Brabham BT46B. A huge fan driven off the gearbox sucked the car to the ground and allowed drivers to corner at virtually any speed they wanted. Niki Lauda handily won the Swedish Grand Prix, the BT46B's first race, but Lotus and other teams threw a fit, ending the short reign of the vacuum car in Formula 1.
Whenever we see No. 3 slapped on the side of a Formula 1 car, it's the 1976 Swedish Grand Prix that comes to mind. Though he hated the car (and quit Tyrrell after the season), Jody Scheckter became the only driver to win a GP piloting a six-wheel car. One of motorsport's truly bizarre moments and one of our favorites.
