The electric drivetrain in the A3 E-tron consists of an electric motor driving the car's front wheels, power-control electronics, an inverter, chargers, a single-gear reduction transmission, and a 26.5-kilowatt-hour battery pack.

The charging port is a standard J1772 receptor, so could be plugged into any standard charging station. Audi says that, from a 220-volt source, the A3 E-tron takes 7 to 8 hours to charge.

The cabin is little changed from a standard A3. The battery pack does not intrude into the passenger space.

Audi changed the gauges slightly, replacing the tachometer with a power usage gauge. Instead of a fuel gauge, the instrument cluster's two smaller gauges show battery level and remaining range, data that can also be seen on the instrument cluster's LCD.

The shifter includes a B mode with Drive, Reverse, Neutral, and Park. B maximizes the regenerative braking in the car.
