Audi of America chief’s remarks spark expected 2012 EV sportscar launch

Reportedly based on the R8 supercar, the e-Tron is 4260mm long and rests on a 2600mm wheelbase – specifications that place it in between the current TT and R8 and have prompted speculation that it will herald another all-new model series from Audi – with conventional as well as electrified powertrains – dubbed the R4.
