Report: Audi Prepping New R4 e-tron Roadster Concept For 2010 Paris Auto Show

Follow Nelson

Our Design Dissection of the 2010 Detroit Motor Show Audi e-tron concept reveals it to be largely a success in terms of aesthetics. So does a cursory glance. But a new version is coming soon, to be unveiled in just a few weeks at the Paris auto show.

Aside from a convertible top, the exterior design is likely to remain the same as the Detroit concept. Little else beyond that is known about the concept.

If it sticks closely to the parameters of the Detroit concept, it will be powered by two electric motors driving the rear wheels alone. That, plus a stealthy battery layout, results in a weight balance of 40:60 front-to-rear. The battery pack weighs 879 pounds on its own.

The rest of the car is made with Audi Space Frame (ASF) tech, meaning aluminum and carbon fiber-reinforced composites combined to form a rigid, lightweight structure. Despite the hefty battery pack, total curb weight for the coupe slips in at 2,976 pounds. The convertible version could weigh as much as 200 pounds more due to internal bracing.

Performance is solid, if not inspiring, at a predicted 5.9 seconds to 62 mph and a top speed of 124 mph. The 155-mile range means you won't be venturing far from home, but it's more than enough to meet most folks' daily needs.

The new Paris e-tron concept and the existing Detroit concept are thought to be near-production designs, so what we see in Paris could be a very good indication of what a few lucky observers will see on the streets as early as 2012.
