Video: Audi A1 Metroproject concept

CNET Car Tech gets video of the Audi A1 Metroproject concept at the 2007 Tokyo auto show.

Audi's metroproject concept presages the Audi A1, set to begin production in 2009. This little car uses a hybrid powertrain, with a gas engine driving the front wheels and an electric motor for the rear wheels. It employs a unique removable smartphone-like device that works as the brains for the car's infotainment systems.
