If the powertrain on this Audi e-tron concept succeeds in terms of range, performance, and durability, it could very well lead to the realization of plans to put an electric car on sale. The Audi E-Tron Concept is currently on display at the 2009 Frankfurt Motor Show. It is speculated that the Audi E-Tron would hint of a Porsche Boxster-sized sports car -- the much-rumored R4.
However, an Audi source suggests that it is not its main role. He said that they don't know yet when the electric road car will be released but that the significance of the e-tron concept is that Audi will develop an electric road car in the future when the technology is right.
In terms of dimensions, the new Audi e-tron concept measures 4.26 m in length and 1.9 m in width, making it shorter and wider than the Porsche Boxster. It makes it possible then that after VW's takeover of Porsche, a platform-sharing deal with Audi is imminent.
A compact two-seater is also a possibility. It is also likely that since the e-tron's electric powertrain is clothed in a sports car shape, it seems that Audi intends to introduce an electric powertrain throughout the range.
Do you agree that this means that it is more likely to appear in a sexy model, such as a small sports car or the A8 flagship rather than the forthcoming entry-level A1 or Golf-based A3? Four electric motors -- one pair at the front and another pair on the rear axle are featured on the powertrain of the new Audi e-tron concept. Total available power is 313 bhp of max output and 3,319 lb.-ft. of peak torque, which is about 10 times that produced by the V8-engined R8.
The new Audi e-tron concept is capable of accelerating from nil to 62 mph in around 4.8 sec, while acceleration from 37 mph to 75 mph takes around 4.1 seconds. On the other hand, the top speed of the new Audi e-tron concept is 124 mph.
The lithium ion battery of the new Audi e-tron concept – weighing around 470 kg -- sits at the front of the vehicle to help achieve a weight distribution of 42 percent to the front and 58 percent to rear. Storage capacity of the lithium ion battery is 42.4 kWh, resulting to an impressive range of 154 miles.
The chassis of the new Audi e-tron concept is a new version of Audi's alloy spaceframe and its body is made from lightweight composite, which contribute to a kerb weight of just 1,600 kg.
