Audi R8 e-Tron Back On Track

The EV world was saddened to learn late last year that Audi was considering killing off the R8 e-Tron electric supercar. But after a thorough review, the project is reportedly back on track…albeit with some key changes to the styling and drivetrain.

Audi was concerned with the cost and performance of an all-electric R8 e-Tron, despite turning in a record-setting lap time at the Nurburgring. Range was also cause for concern, and a review of the project saw some pretty important changes to the styling that drastically reduced the drag coefficient down to just 0.27.

While the normal R8 utilizes all-wheel drive, the e-Tron model is expected to send power to just the rear wheels. Two electric motors put out a combined 376 horsepower and 604 ft-lbs of torque, though top speed on the production model will be limited to just 125 mph. This will allow for a real world driving range of between 100 and 130 miles.

The Audi R8 e-Tron is expected to weigh just under 4,000 pounds, despite carrying a battery pack that weighs nearly 1,300 pounds alone. Extensive use of carbon fiber and newly-developed lightweight springs are just a few of the components that helped keep the weight in check.

A very limited production run is expected to be announced for sale sometime in the next year, though it seems as though Audi has scaled back expectations. We’re just glad there will soon be another all-electric supercar hitting the streets and joining the likes of the BMW i8 and Mercedes SLS AMG Electric Drive.
