In 1982, Williams designer Patrick Head revisited Tyrrell's previous concept of the six-wheel Formula 1 car.
While the Tyrrell's P34 was designed with two small wheels at the front, Head opted for a four-wheel drive concept at the rear, an approach destined to benefit traction but also downforce by extending the free flow of air all the way to the rear axle.
Unfortunately, the FIA banned six-wheel cars, alleging that the concept would drive up costs and cause chaos during pitstops.
According to Head, the car's traction out of the corners was phenomenal.
But the radical design suffered from one major issue: the car was just too "bloody heavy", according to the Williams' engineer.
