Audi A3 E-Tron goes carbon neutral with German green electricity deal

Audi is proving that the fresh water flowing through the European Alps isn't just for bottling and drinking anymore. The German automaker struck a deal with Hamburg-based LichtBlick to offer buyers of the Audi A3 Sportback E-Tron a chance to get their electrical juice from all renewable-energy sources. That means all the power going into charging stations can come from hydroelectric power from Germany, Austria and Switzerland. The nuts and bolts part of it is that users pay the equivalent of about $12.30 a month plus 37 cents per kilowatt hour for the service. And LichtBlick is indeed legit, as it has been certified by TUV Nord for having at least one third of its power come from hydroelectric plants that are were built less than six years ago. Audi is looking to boost sales from a model it unveiled at last year's Geneva Motor Show. The car pairs a turbocharged 1.4-liter four-cylinder engine with an electric motor that combines for 250 horsepower. Most importantly, the A3 E-Tron gets a combined fuel economy rating of 157 miles per gallon. And while that figure comes from the more generous European driving cycle, it's impressive nevertheless.

Next Audi R8 to share hybrid tech with Lamborghini Asterion

The second-generation Audi R8 isn't far away, but when it arrives, it could serve to seriously shake up the supercar market according to Audi research and development boss Ulrich Hackenberg.
Speaking to Car in the UK, Hackenberg confirmed quite unequivocally that a plug-in-hybrid model and a pure electric were coming. And as with the current R8, the next-gen model will borrow from Audi's Italian cousins at Lamborghini.
"We are able to make the R8 a plug-in hybrid," Hackenberg told Car. "The Lamborghini Asterion shows this is possible - that car uses the platform of the R8. We will see an increase in the efficiency of high-performance cars - they have to meet CO2 regulations of the future in order to survive."
