The German car manufacturer Audi has shown its second all-electric drive at the first major auto show of 2010 in Detriot. The new E-tron is 3.93 meter (154.72 in) long, 1.78 meter (70.08 in) wide and just 1.22 meter (48.03 in). The two-seater weighs only 1,350 kilograms (2976.24lb) and has an ASF-design aluminum body.
The vehicle uses the same setup where four electric motors are connected to each wheel. Its “torque vectoring” is the key to a thrilling level of active precision and excellent traction. 0 to 100km/h (62mph) is done in just 5.9 seconds. The Audi e-tron accomplishes a sprint from 60 to 120km/h (37.28 – 74.56mph) in a mere 5.1 seconds. The vehicle is limited to 200km/h (124mph).
The lithium-ion batteries are located behind the passenger compartment and ahead of the rear axle. They make an effective energy content of 45 kilowatt-hours available, creating an operating range of up to 250 kilometers (155.34 miles) realistically possible. Wheels are 19-inch size with a 35-spoke design, 235/35 tyres up front and 255/35 tyres at the rear.
Audi again uses the same setup regarding the componentes: a heat pump as an efficient means of heating up and maintaining the interior temperature. The drive system, power electronics and battery have a thermal management – crucial for maintaining a high operating range coupled with the correct interior comfort.
