What is it? Audi unveiled a second compact electric car concept in Detroit that's similar to one unveiled in Frankfurt and Los Angeles a few months ago, which is also called the e-tron. Audi is using the e-tron name as a sub-brand, similar to how it uses "Quattro," that will be applied to a number of different vehicles. The Detroit e-tron is smaller and lighter than the previous e-tron weighing in at just under 3,000 pounds. Two electric motors on this rear-wheel drive vehicle produce a combined 204 hp. With the aluminum body and coupe design, Audi claims it can go 0-62 mph in 5.9 seconds.
The lithium-ion batteries are located behind the passenger compartment and in front of the rear-axle of this two-seater, which helps save energy and allows a possible driving range of 155 miles. Another energy saving feature is the use of a heat pump, which heats up and maintains the interior temperature.
