Rubert Stadler, Audi's automaker chairman commented on plans to expand the e-tron line beyond the R8 model next year. They are reportedly going to include a plug-in hybrid version of the next generation A4 and Q7.

2014 will be the Audi A3's debut being the first model out of the gate with a plug-in option.

Stadler went on to say that by 2020, Audi will have an e-tron version of each vehicle it offers in every segment, which in all likelihood will be either a pure electric model or some form of hybrid.
