A new performance variant of the Audi RS6 Avant will become the sole version sold in the UK when it is launched in December. Fitted with a larger turbocharger, the 4.0-litre V8 has been uprated to deliver 621bhp and 627lb ft (up 30bhp and 37lb ft), reducing its 0-62mph time by 0.2sec to 3.4sec. Lightweight 22in wheels and a self-locking centre differential come as standard. It will cost £130,050 in top-spec Vorsprung trim.
