Nov. 11, 1976 - March's Six-wheeler racing car with a difference: An answer to the problem of the drag caused by enormous rear tyres need on grand prix cars is proposed by designer Robin Herd in the experimental March Formula I car announced yesterday - it will have four wheels at the rear. This could reduce the frontal area by as much as 20 per cent, but the first four-wheel drive Grand Prix car since several unsuccessful attempts in 1969 is 100 pound heavier than the average Ford-powered machine. The March four-wheel drive system consists basically of a second differential, driven by a pinion shaft coupled to the back of a normal Hewland gearbox. herd's unique system ca be bolted on in three to four hours. If tests are successful, a March-Ford six-wheeler could be racing in this South African Grands Prix four months from now. Photo shows the new March four-wheeled rear drive racing car
