导读：特斯拉电动汽车火了以后，各大车企都不敢再消极等待，BBA三剑客中奔驰和宝马已经推出纯电动汽车，并且建立了电动汽车子品牌。而奥迪一直没有跟进，只是推出几款混动汽车。这次奥迪终于坐不住了，准备推出一款电动SUV，名为E-Tron。类似宝马的i系列，奥迪今后将推出E系列电动汽车。原文： With BMW and Mercedes both building electric sub-brands， one automaker has been left out of the electric conversation: Audi. However， information from Audi helps shed some light on the Audi electric situation， and it starts with an SUV. Audi chairman Rupert Stadler said Audi's new electric SUV will be called the E-Tron. He told the publication the naming scheme would be similar to how Audi introduced Quattro all-wheel drive with a car named after the feature. Also like Quattro， Stadler said other Audi models with electrified powertrains will receive E-Tron suffixes. In a way， it will be like BMW's naming scheme with the i sub-brand; some models are just referred to by the i designation， while normal models with hybrid or electric powertrains have names such as iPerformance. Autocar also revealed that other electric-only E-Tron models will come later， probably in the forms of a hatchback and a sedan. This news also shows that Audi hasn't given up on electric car development. Just last week， the companykilled off its R8 E-Tron electric supercar. While the move raised some eyebrows here， since the R8 E-Tron could have been a great electric halo car for the new brand， it seems Audi is more interested in mass-market electric vehicles. The R8 E-Tron， which cost $1，000，000， sold fewer than 100 units and could only be purchased by getting in touch with Audi directly， didn't really fit that bill.
