For success matched only by sheer diversity, few can hold a light to engineering ace Tony Southgate.

Designer of Bobby Unser's Indy 500-winning Eagle 68 car, a key contributor to the trailblazing ground-effect Lotus 78 and the creative mind behind Jaguar's Le Mans-conquering XJR-9, the Coventry native has marked himself out as one of racing's great lateral thinkers.

Along the way, Southgate worked with some of its greatest drivers, including Mario Andretti, Pedro Rodriguez and Dan Gurney.

In the newest episode of our podcast series, in association with Scalextric, Southgate pulls back the curtain on some of motor's sport seminal moments.
