BRM_P153 Knowpia

The BRM P153 was a Formula One racing car designed by Tony Southgate for the British Racing Motors team, which raced in the 1970, 1971 and 1972 Formula One seasons. It was powered by a 3.0-litre V12 engine. Its best result was victory at the 1970 Belgian Grand Prix, where Pedro Rodríguez beat the second-placed March of Chris Amon by just 1.1 seconds.^[1] The model was first shown in BRM's traditional British racing green, but by the time it appeared on the race tracks it was in the colours of the team's sponsor, Yardley of London.

Engine edit

In contrast to the other British teams, amongst whom the Cosworth DFV V8 had become nearly ubiquitous, BRM chose a different route for the P153's engine. In accordance with their long-standing practice of building both chassis and engine, they installed their existing 3.0-litre, 48-valve V12 engine, that produced approximately 435 bhp (324 kW), with a redline of 11,000 RPM.^{[citation needed]} Magneti Marelli supplied their Dinoplex ignition system, and Lucas provided mechanical fuel injection.

Gearbox edit

Its gearbox was a sequential BRM P151 type with 5-speeds with reverse, which was connected to the engine by a Borg & Beck clutch.

Chassis edit

It had an aluminium monocoque with tubular support attached to the engine. Its total weight was 535kg.
