Review: Audi TT RS

If an engine note defines a brand then Jaguar would be a growling twin-cam straight six, Porsche a yowling air-cooled flat six, and Audi a guttural five-pot turbo. Audi wasn't the first to lay claim to the straight five-cylinder configuration (Mercedes-Benz, Lancia and Honda have antecedents), but it did define that belting second-order harmony way back in 1977, with the Audi 100E, its first five-cylinder unit.
