Joining the e-tron in 2020 will be the more aerodynamic Sportback version. Its sleeker body helps to boost the range to 278 miles.
Other tweaks maximise efficiency. These include drivetrain modifications that allow it to run in rear-wheel-drive only. The E-Tron Sportback 55 develops more than 400PS in Sport mode, allowing it to sprint from 0-60mph in under six seconds.
Likely to cost in excess of £70,000, it is available with digital matrix LED headlights and camera-based rear-view mirrors.
