However, it is important to note that only 31 miles of that range is electric, while 553 miles of it is gasoline. For eco-conscious drivers preferring an electric vehicle, this might not compete with Tesla’s vehicles. Tesla Motors Inc ( TSLA)’s Model S sedan has a 250 to 300 mile range on electric power only. A key part of the argument putting the 2017 A3 e-Tron as a competitor for Tesla’s cars is going to be the technology behind how the vehicle manages 553 miles on gasoline. Miles per gallon will be important here.
