Mystery BMW "Z29" unveiled

BMW has apparently put together a prototype lightweight coupe called the Z29. Based on the Z4, the car is said to weight just over 2,500 pounds. It features the same engine as the Z4 M and M3, and is built of aluminum and carbon fiber. 0-62 mph takes around four seconds. Further details remain very sparse, and it's not clear if the car is a project between BMW and a tuner, or if hints to a forthcoming model. We'll keep you posted as this story develops.
