Matra MS84
The Matra MS84 was the fifth Formula One car produced by Matra (following the MS9, MS10, MS11 and MS80). Development The car was built at Matra's Formula One base at Vélizy-Villacoublay in the southwestern suburbs of Paris, designed under the direction of Bernard Boyer and built by Jean Bee (a.k.a. "Bunny") under the direction of Legan. It was run by the Matra International team of Ken Tyrrell with full technical support from Matra and the financial backing of Elf. Although it has a family resemblance with the MS80 with which Matra won the 1969 Constructors' Championship, it is a completely different car with a steel tube chassis instead of an aluminium monocoque. At the back the engine is mounted back-to-front with the gearbox and transfer case directly behind the driver. The four wheel drive system was designed by Derek Gardner of Harry Ferguson Research. The Ferguson transmission and other necessary additions left the car much heavier than the two-wheel drive MS80s (635 kg with no fuel). Racing history Like the Lotus 63, the MS84 made its first appearance at the Dutch Grand Prix, where Jackie Stewart tried the car out but opted to use his MS80, as he would for
