According to a recent report, Audi has axed their diesel-electric supercar to focus on the Sport Quattro concept.

Audi's diesel-electric supercar has been axed, according to a recent report.

Car and Driver says the model, rumored to be codenamed Scorpion, has been shelved in order to focus on the Sport Quattro concept which is expected to debut at the Frankfurt Motor Show. Little else is known about the decision but the magazine says it has drawn ire from some corners of the company.

As we have previously reported, the Scorpion was expected to be based on the Le Mans winning R18 e-tron quattro. Speculation suggested the model would be powered by a 100 bhp (74 kW) electric motor and a turbocharged 3.7-liter V6 diesel engine that produced 600 bhp (447 kW).
