High Quality Content by WIKIPEDIA articles! Saab Aero-X is a concept car by Saab unveiled at the 2006 Salon International de l'Auto. It is powered by a 2.8 L twin-turbocharged V6 running on pure ethanol that produces 300 kW (400 hp). 0 to 100 km/h (62 mph) is predicted to be 4.9 s and top speed is limited to 250 km/h (155 mph). It has a 7-speed manual transmission controlled by paddles on the steering wheel.Like the American-market Saab 9-2X, the Aero-X has four wheel drive. The doors and windscreen are connected, so instead of using conventional doors or even gullwing doors, it uses a cockpit canopy where the entire top section of the car is opened. This offered the Aero X's driver full 180 degree vision, and also facilitates entry and exit from its low-slung cabin. The body is made of carbon fiber. The suspension is electronically-controlled. Even though it is a compact two-seat sports car, it has reasonable storage, as the rear features two storage facilities, with a conventional hatchback and sliding drawer underneath.
