Audi Presents The A1 e-tron Electric In Geneva
GENEVA, SWITZERLAND - Audi debuted a revolutionarty new concept hybrid electric car at the 2010 Geneva Motor Show this week called the Audi 'A1 e-tron'. Audi refers to the A1 e-tron as a Mega City Vehicle (MCV) for its urban mobility status. The A1 e-tron's drivetrain is entirely electric and utilizes an electric motor with a peak output of 75 kW (102 hp), giving it brisk acceleration.Â
To extend the range of the A1 e-tron electric car, Audi engineers have integrated a 254 cc small single-rotor gasoline engine running at a constant 5000 rpm for efficiency. The Wankel engine operates as a generator to charge the Audi e-trons lithium-ion battery pack when its charge is becoming depleted. The Wankel engine range extender can be activated manually if the driver knows they are about to commence a long journey. The engine is powered by a 12 litre (3.17 US gallon) gasoline fuel tank.
The 4-passenger A1 e-tron electric hybrid car has a zero to 100 km/h (62.14 mph) acceration time of 10.2 seconds and can reach a top speed of over 130 km/h (80.78 mph). For the first 50 km (31.07 miles) the Audi e-tron operates as a zero emissions vehicle powered entirely by its 12 kWh (380 volt) lithium-ion rechargeable battery pack. The battery is shaped in a T-shaped volume and is mounted in the rear central tunnel of the car to save space. Â The battery pack itself weighs 150 kg (330.69 lbs) and is made up of 96 prismatic cells.
Audi says the A1 e-tron has been designed specifically for operation in metropolitan urban areas situated in Europe, North America, Asia and South America. The electric motor in the A1 e-tron is mounted low in the vehicle, giving the car a low centre of gravity, which helps to improve cornering. The torque output of the electric motor is 150 Nm (110.63 ft-lbs) continuous, and a peak torque of 240 Nm (177.01 ft-lbs) of torque is available for short bursts.
The Audi A1 e-tron electric hybrid car has been designed primarily for use in the city and when the range extender 254 cc Wankel engine is used to charge the battery, the car can travel a driving distance of up to 200 kms (124.27 miles). The electric battery pack can be charged off of a home outlet or by using a commercial quick-charger. Based upon a draft standard for dual-mode powertrains, the Audi A1 e-tron has a fuel consumption of 1.9 L/100 km (123.80 US mpg) with a CO2 emissions output of 45 g/km.
