McLaren Cars by Type #

M14A - 1970
Three 1970 Formula 1 cars were built at the start of the season. The design team of Bruce, Gordon Coppuck and Jo Marquart had made several important innovations. The most notable was to mount the rear brakes inboard in an effort to save unsprung weight.

Chassis: Full monocoque with aluminium and magnesium panelling bonded to fabricated steel bulkheads, terminating behind the rear cockpit bulkhead and using the engine as a fully-stressed chassis member.
Suspension: Single top link with radius arm, lower wishbone, anti-roll bar and outboard coil spring/shock units in front. Single top link, reversed lower wishbone, twin radius arms and outboard coil spring/shock units at rear. McLaren cast magnesium wheels, 15 x 11 front and 15 x 16 rear.
Brakes: Lockheed ventilated discs all around, 11.66-inch diameter front and 10.90-inch diameter rear mounted inboard.
Body: Formed by monocoque sides with detachable fibreglass nose cone and cockpit surrounds.
Engine: Cosworth-Ford DFV 3-litre V-8 with Hewland DG300 5-speed transaxle.
Dimensions: Wheelbase 95 inches, front track 62.4 inches, rear track 60 inches, length 156 inches, weight 1180 pounds.
