The next-generation Audi A7 Sportback has yet to make its debut, but already the new hatchback-cum-coupé has been caught completely in the buff. Well, in scale model form at least, as shown in an image procured by Dutch publication AutoWeek.

A sole front three-quarter shot reveals that the styling of the new A7 will be evolutionary rather than revolutionary, with similar proportions and the same sloping roofline as before, although the teardrop shape of the side windows seems to have been elongated. The rear deck also appears to be taller, avoiding the slightly droopy look of its predecessor’s rump.

The front end is where most of the changes lie, with a flatter, broader Singleframe grille flanked by simpler trapezoidal headlights. Along the side, there are more prominent haunches over the front and rear wheels to emphasise the quattro all-wheel drive system, while the rear is expected to feature full-width tail lights as seen in previous spyshots (and the new A8).

Like the new A8, the next A7 will ride on the revised MLB Evo platform, although it will likely ditch the flagship’s predominantly aluminium construction for a mostly steel body. Even so, it should drop a few hundred kilos in weight compared to the outgoing model.

Engines will likely include revised four-cylinder and V6 engines, taken from both the new A4 and A8; a 4.0 litre twin-turbo V8 is also expected in the sportier S7 and RS7 models. All models should come with an eight-speed automatic transmission and, like the A8, a 48V mild hybrid system. Also expect the full range of self-driving features from the A8 that will enable Level 3 autonomous driving at speeds of up to 60 km/h.
