Motorsport tends to have periods of time where one team or constructor is always on the top step of the podium. Is that a problem, or is it just the nature of the sport? We try to answer that question by looking at a number of dominant cars across the racing spectrum. In this episode we look at Audi's domination at Le Mans with their R8, R10, R15 and R18 prototypes, the revolutionary STP-Paxton Turbocar from the 1967-68 Indy 500 and several Formula 1 cars, including Mclaren's MP4/4, Ferrari's F2002 and F2004, and the recent Mercedes turbo cars.
