The BRM P351 was originally a Group C sports-prototype built for the 1992 World Sportscar Championship season in an attempt to resurrect the British Racing Motors marque. The car later reappeared in a heavily modified form in 1997 as a Le Mans Prototype known as the BRM P301 before retiring completely in 1998. Only one chassis was ever built. The project was also connected to the failed BRM P401 sports car which would have shared some elements of the P351 race car. BRM P351 designer Paul Brown completed the drawings and a full-size cockpit was manufactured by Motor Panels. However, with the ending of the race programme, the P401 project was shelved. Development In 1990, an agreement was reached between entrepreneur John Mangoletsi and the family of British Racing Motors (BRM) founder Alfred Owen, who had retained the naming rights to the company even after it had ceased to exist. The use of the BRM name would help Mangoletsi's project gain sponsorship and funding by appearing as a manufacturer entry against the likes of Toyota, Peugeot and Mazda in the World Sportscar Championship. With the backing of BRM, Mangoletsi turned to former Zakspeed chief engineer Paul Brown to design the car. Brown was employed at the time by Airflow Management and had extensive experience of state-of-the-art sportscar design, having previously been involved with update work on the Porsche 962 for Porsche Motorsport North America and a sportscar project for General Motors that did not come to fruition. Brown produced a conventional carbon composite monocoque Group C chassis, which although technically unremarkable was well regarded by those who drove it for its excellent handling. The composite chassis of the car was constructed for the team by the engineering firm Courtaulds and finished in a metallic british racing green with BRM's traditional orange nose. The engine was designed by Graham Dale-Jones and built by Terry Hoyle's JHS company using a block derived from the Weslake V12 Grand Prix unit. It was branded as a 'BRM'. Claimed output was at 11300 rpm but it proved to be uncompetitive and unreliable. Dale-Jones virtually redesigned the V12 which actually exceeded its performance targets and further validation work on the engine was carried out by Ricardo Engineering. A model of the BRM P351 was exhibited at the Autosport Racing Car Show in January 1991 and the complete car was unveiled in London’s Science Museum in November
