At the age of nine, Bruce McLaren was diagnosed with Perthes disease, a rare childhood bone disorder that affected his left hip and forced him to spend more than two years in hospital with his leg immobilized in a traction device. Rather than stopping him in his tracks, this challenge ignited a passion for mechanics and racing cars, fueled in part by his father, who ran a service station in Auckland. McLaren’s full journey is explored, starting from local races in New Zealand, to his early triumph in Formula 1, when he became the youngest Grand Prix winner at age 22; to the founding of Bruce McLaren Motor Racing Ltd in 1963, and his untimely death in 1970 during a test run of the M8D at the Goodwood Circuit.
