In the fourth volume of this unique, commemorative, four-part series, motorsport historian Neville Hay recalls the final days of BRM and their GP victories, the story behind the complicated H16 and the departure of Graham Hill and Tony Rudd.

Jackie Stewart, Richard Attwood, Tim Parnell, John Surtees, Peter Gethin, Jean-Pierre Beltoise, Jackie Oliver and Tony Rudd describe BRM’s finale and how the company struggled to cope with the changing face of GP racing. David Owen, eldest son of Sir Alfred Owen and the Chairman of Rubery Owen Holdings together with Louis Stanley (brother-in-law of Alfred Owen) provide a fascinating insight into the running of the team and the enormous involvement of the Owen family

In 1974 BRM retired from racing and Raymond Mays and Peter Berthon’s dream came to an end. But BRM had left a lasting legacy - they brought motor racing into Britain's public consciousness and enabled British motor sport to lead the world.
