Audi has reportedly pulled the plug on the production of its all-electric Audi R8 e-Tron supercar. The Audi R8 e-tron was launched at the 2015 Geneva Motor Show and it was exclusively offered to European customers and had a price tag of $1.1 million.

In the time since it went on sale, Audi has built less than 100 copies of the R8 e-tron, according to a report from Car and Driver.

“We could have built more than we did,” an unnamed Audi representative told Car and Driver without giving any details as to why the e-tron is being discontinued.

The Audi R8 e-tron was first displayed at the 2009 Frankfurt Motor Show as a concept car. The production car produced 456 horsepower and 679 pound-feet of torque. Audi quoted a 0 to 60 mph time of 3.9 seconds, with an electronically limited top speed of 155 mph and returned all-electric range of up to 280 miles.

Audi’s next electric car will be an electric SUV based on the e-tron quattro concept from the 2015 Frankfurt Motor Show. Audi has promised a range of around 300 miles, and plans to begin production in 2018.
