BRM P153
The BRM P153 , also known as the BRM P153 , was a Formula 1 racing car , built and used from 1970 to 1972 by the British Formula 1 team British Racing Motors .
BRM, the 1962 world championship team, brought in designer Tony Southgate in 1969 to build a new car. Southgate modified the P139 before starting the design for the P153. The car had a simple and lightweight monocoque in the shape of a bathtub, which became the trademark for this vehicle and its successor, the P160 . In the two bulging flanks, left and right of the cockpit, were the tanks. The suspension was conventional, only the brakes were moved outwards on all four wheels, an unusual idea for 1970 (standard today). The P153 was the first BRM to appear not in green (the color of the British racing teams), but in the livery of sponsor Yardley.
The heavy but powerful V12 engine has been thoroughly redesigned to be closer to Cosworth's V8s. The car was handy, easy to set up and was generally considered a good hit.
Pedro Rodríguez won the Belgian Grand Prix in Spa-Francorchamps in 1970 and achieved the first Grand Prix victory for BRM since Jackie Stewart's success in Monaco in 1966. Although the P160 followed in 1971, the P153 was further revised and brought to the start for the third and fourth drivers in the team (BRM temporarily used four works cars). It was still running as the P153B in 1972, but it already had the wheel suspension of the new P160.
