Mid-life refresh time for the Audi A6, which means the brawny S6 gets to enjoy a few updates of its own. Minor styling tweaks include meaner-looking LED headlights and altered air intakes carved into re-profiled bumpers, but comparing old with new is a pretty tough game of spot-the-difference.
So what’s new on the 2015 Audi S6?
More likely to capture attention is the hike in power. As before, the engine bay’s generously filled out by a 4.0-litre twin-turbo V8 with fuel-saving cylinder-on-demand tech. Audi’s engineers have liberated another 30bhp to bump its total up to 444bhp, while somehow simultaneously lowering CO2.
It’s hardly surprising they’ve unlocked more power so easily: with everything turned up to 11 in the RS6, the same unit churns out 552bhp.
