Say the words"sports car made in Germany"and many people will think of Porsche. Its cars have always been the ones to beat on the race track but now there's a challenger vying for Porsche's crown.The BMW Series 1 M Coupe is set to take on Porsche's lightweight track missile, the Cayman R. Both cars have six-cylinder engines and nearly identical performance. The BMW has the engine in the front, the Porsche has it in the back, but both are rear-wheel drive. Can the BMW pull ahead of the Porsche?
