The Audi e-tron 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 A3 Sportback e-tron, released to retail customers in Europe in August 2014, and slated for the U.S. in 2015. A decade after the unveiling of the first e-tron concept at the 2009 International Motor Show Germany, Audi’s first fully electric e-tron SUV went into production in 2019. The name has also been used on some racing cars.
