GM is unveiling the Saab Aero X two-seater sports coupé concept at the Geneva motor show. Taking design cues from Saab’s aviation heritage, the Aero X has no door or windshield pillars; the car adopts a cockpit canopy instead.

The Aero X features a new 400 hp (298 kW), twin-turbo, BioPower V6 engine that is fueled entirely by ethanol (E100), thereby offering net zero tank-to-wheel CO₂ emissions.
