The Sportback gives the crossover a sleeker rear while retaining the rest of the E-Tron's strengths.

Audi has a production version of its E-Tron Sportback concept on the way later this year, and it'll broaden the brand's lineup of EVs. With test prototypes already under development on the road, this rendering imagines how the electric crossover might look.

The E-Tron Sportback's look starts with the existing crossover, and the designers sculpt the rear section of the roof to give the vehicle a sleeker silhouette. This limits headroom for folks in the second row and decreases cargo room but gives the exterior a more flowing shape.

The Sportback would likely be mechanically identical to the existing E-Tron. It offers an electric motor at the front and rear that produce a maximum of 402 bhp in S mode or 355 bhp in the normal D mode. There's a 95-kilowatt-hour battery pack that provides a 248-mile range rating for the existing model. The SUV can reach 60 miles per hour in 5.7 seconds, and there's an electronically limited top speed of 124 mph.

In concept form, the E-Tron Sportback made 430 bhp during normal driving or 496 bhp from the boost mode. Rumours suggest that Audi has a more powerful electric drivetrain under development, so it's possible the more potent variants could join the lineup relatively soon.

On the inside, the E-Tron Sportback should also be similar to the existing model (above). It offers a pair of touchscreens on the centre stack – one for the centre stack and another for the HVAC system.

After the E-Tron Sportback joins the lineup, a five-door grand tourer EV should arrive. There are rumours of an electric supercar coming eventually, too.
