The Audi e-tron family is a series of electric and hybrid concept cars shown by Audi from 2009 onwards. In 2012 Audi unveiled a plug-in hybrid version, the Audi A3 Sportback e-tron, released to retail customers in Europe in August 2014, and slated for the U.S. in 2015
As this car is still in concept phase, much of its performance specifications are still uncertain. The car will have four electric motors, one per wheel. Together, these motors will produce 3,320 pound-feet (4,500 N·m) of torque. Top speed for the e-tron is limited to 222 kilometres per hour (138 mph), and it will be able to travel 150 miles (240 km) on full charge.
In concept form, the e-tron also is equipped with conceptual technology: technology that communicates with other cars, road signs, etc.
