Audi has confirmed that its all-electric supercar, the R8 e-tron, will no longer be built.
Speaking to headlineauto, Audi head of research and development Wolfgang Durheimer said: "At the moment I don't see an economically interesting business case with the price and the energy density we would be able to deliver [with current battery technology]."
"Each car costs us €1 million. It cannot be subsidised by the customers for our existing vehicles and we are not willing to lose money selling it. But the R8 e-tron is a showcase for what is possible, and our findings from developing it will find their way into all future Audi applications of e-mobility."
10 R8 e-trons have already been built; however, Audi is not allowed to sell them. They are currently undergoing a testing programme, but will likely be turned into museum pieces when the programme ends.
The R8 e-tron was originally intended to be an all-electric supercar to rival the likes of Mercedes' electric SLS and was fitted with two electric motors delivering a combined 375bhp and 605lb-ft of torque.
0-62mph took 4.6 seconds and the top speed was limited to 124mph; however, Audi upped this limit to 155mph when the car smashed the lap record for electric cars at the Nurburgring last year.
