Here is another e-tron concept from Audi that is a plug-in hybrid which seems to be all the rage these days. This car is based on the A3 sedan concept revealed earlier this year. The car has a 1.4 liter turbo four cylinder putting out 211 horsepower and this is combined with a 27 horsepower electric motor for a total of 238. A 7 speed DSG is the transmission of choice. This would be a relatively sporty and green car if it wasn't for the weight penalty of the battery and electric motor adding almost 400 pounds for a total of 3,792.
