Audi RS7 Sportback
Why 8.0: A fastback saloon that does 0–100 in 3.6 seconds while looking broadly like a well-optioned A7. High annual mileage for a £100k car; these get used as daily drivers by people who need a quick answer to ‘what car do you drive?’

Sound
The hot-vee 4.0-litre has a low, even burble and a decent crack on lift. But Audi both muffles it and pipes a synthesised layer into the cabin, so the bodywork is not the only anonymous thing here — it is background noise rather than character.

Euro NCAP confirms the A7 shares the A6's rating, including front ISOFIX as a cost option rather than standard fitment.
Applies most directly to the current C8-generation RS7 (2020-); the earlier C7 (2013-2017) wasn't independently re-verified here.

The long version
The RS7 buyer’s pitch is anonymity at speed: quattro AWD, 600-ish horsepower under an A7 body, an interior that could pass for executive transport until the driver finds a gap in traffic. That combination — proper supercar pace, four-door practicality, understated styling — means the annual mileage on used examples runs high by performance-car standards. People buy this to use it, not to photograph it. Values depreciate at a healthy clip after the first three years, which is when the second wave of enthusiast buyers arrives and the mileage really starts to accumulate. Both generations earn the same verdict: the sleeper that drivers actually drive.
