The BRM P83 was a Formula One racing car designed by Tony Rudd and Geoff Johnson and built by British Racing Motors for the new engine regulations of 1966. It used a highly unorthodox H16 engine which caused problems throughout the car's racing life, and despite the best efforts of Graham Hill and Jackie Stewart took BRM from championship contenders to also-rans, leading it to be regarded alongside the BRM Type 15 as another embarrassing failure for the British marque caused by overcomplicated engineering.
