Audi reveals the electric e-tron

Audi presented the e-tron, a high-performance sports car with a purely electric drive system.

Four motors – two each at the front and rear axles – drive the wheels, making the concept car a true quattro. Producing 313 h.p. and 3,319.03 lb.-ft. of torque, the two-seater accelerates from 0 to 62.14 mph in 4.8 seconds, and from 37.28 - 74.56 mph in 4.1 seconds. The lithium-ion battery provides a useable energy content of 42.4 kilowatt hours to enable a range of approximately 248 kilometers, or 154 miles.

Audi has taken a new, and in some cases revolutionary, approach to many of the technical modules. A heat pump is used to efficiently warm up and heat the interior. The drive system, the power electronics and the battery are controlled by a thermal management system that is a component for achieving the car’s range without compromising comfort.
