Despite the lack of a new name, Audi's latest take on its e-tron EV for the 2010 Detroit show is in fact a unique concept. As with the first e-tron that debuted at last year's Frankfurt show, the Detroit show e-tron concept is based on the R8's aluminum spaceframe, but is more than a foot shorter than its predecessor and nearly 500-pounds lighter. Perhaps most surprisingly, the Detroit car loses its front electric motors, meaning it does not feature Audi's signature quattro all-wheel drive. Instead, two motors mounted on the rear axle combine for an estimated 201 hp and 1955 lb-ft of torque (the latter figure apparently continues Audi's highly suspect practice of providing multiplied torque figures).

The result is a concept that's slightly less capable than the original e-tron (0-62 mph takes an estimated 5.9 seconds) but potentially more fun thanks to its small size - it looks positively diminutive next to an R8 -- and relatively light weight (less than 3000 lbs). It would also presumably be less expensive, though that too, would be relative given the price tag of more than $150,000 Audi will likely place on the first e-tron when it goes on sale in 2012. As with the Frankfurt e-tron concept, lithium-ion batteries mounted behind the driver provide an estimated 155 miles driving range for the Detroit show car, according to Audi.
At the moment, Audi is calling this variant an "experiment." However, the company makes no secret of its intent to market e-tron not just as a name for one vehicle, but as a distinct sub brand not unlike quattro and TDI. The concept also makes plain Audi's intent to very gradually trickle down its electric vehicle technology into more affordable products. -David Zenlea
