Race on Sunday, sell on Monday - it's long been the mantra of car companies across the world and an excuse for many manufacturer MDs to indulge their passion for motorsport.

The idea is a simple one: Prove to the masses on race tracks around the globe that your cars are capable of beating the best and hopefully it'll equate to sales in showrooms. Interestingly that wasn't how it worked with the Cosworth brand. Well, not at the outset any way.
