The famous fan car, introduced at the 1978 Swedish Grand Prix as a counter to the dominant ground effect Lotus 79. The BT46B generated an immense level of downforce by means of a fan, claimed to be for increased cooling, but which also extracted air from beneath the car. The car only raced once in this configuration in the Formula One World Championship, when Niki Lauda won the 1978 Swedish Grand Prix at Anderstorp. The concept was declared illegal by the FIA before the car could race again. The BT46B therefore preserves a 100% winning record! This model can be built as either the #1 car of Niki Lauda or #2 car of John Watson at the 1978 Swedish Grand Prix. Molded in white and black plastic, with chrome parts, engine detail, black rubber tires, a deep blue windscreen, and decals.
