After showing you initial design sketches of the Audi A2 concept car here: http://www.eurotuner.com/news/eurp_1109_audi_a2_concept/index.html
Audi is now revealing more complete renderings of its third electric-powered car to be unveiled at Frankfurt.
Power for the electric motor, mounted within the sandwich floor, is provided by a lithium-ion battery. After a 1.5-hour 400-volt charge or 4-hour 230V charge, the car will have a reported 124-mile range from its 116hp motor with and200 lb-ft of torque. This is said to permit 0-62mph in 9.3 seconds and a 93mph governed top speed.
With its reliance on battery power, the car must be both light and efficient. Therefore, it will have shift-by-wire, brake-by-wire and steer-by-wire contactless technology. It will also weigh only 2535 lb with the help of multi-material hybrid construction.
The concept also uses very advanced lighting systems to save energy, alert other drivers, and create interior ambience.
The A2 concept is purely electric, using a lithium-ion battery mounted in its sandwich floor to store 31 kWh of energy, 24 kWh of which is usable.
The electric motor is transversely mounted in the front, and delivers 116hp peak power (80hp continuous) and 200 lb-ft of torque (120 lb-ft continuous) to the front wheels via a single-speed transmission.
This permits a 0-62mph acceleration time of 9.3 seconds and a top speed of 93mph, limited in the interest of driving range, which stands at 124 miles according to the European driving cycle test.
