These grainy images were captured from quite a distance away while the test mule was travelling at high speed for testing purposes on the salt flats.
The four-door coupe-like A7 will be just as exclusively equipped as the A8, maintaining Audi's current design philosophy.
Unlike the A8 however, entry-level models will start at the top of the food chain in the performance stakes, with customers likely to be offered a choice between the 4.2-litre V8 FSI and Audi’s new 6.0-litre V12 TDI.
Reports indicate the brand's 6.0-litre W12 engine is being phased out due to cost and emissions issues, meaning it is unlikely to feature in the A7 range.
Despite its performance credentials, some base models are expected to be front-wheel drive along with an optional Audi quattro all-wheel drive system.
