Perhaps we should have tagged this story NSFW. It’s the Audi RS6 Avant Nogaro Edition, and if you like a fast estate, it’s basically filth.

Just 150 will be made, but they’re all for Germany. As the RS6 nears the end of its life, it’s essentially a greatest hits package of all its best options: ceramic brakes, sports differential, polished 21in wheels, titanium exhaust… and the performance pack that brings 597bhp/750Nm peaks, enough for a 3.7sec 0-100kph time and 304kph top speed. Yikes.

If you’re scratching your head thinking that’s not enough, then Audi has taken your loopy requirements into account, too. The Nogaro Edition has also seen a tie up with tuner ABT Sportsline, who’ll boost the 4.0-litre twin-turbo V8 up to 695bhp and 880Nm. Thus equipped, you’ll be able to hit 319kph the next time you’re on empty, derestricted autobahn.

Wondering what the name means? Nogaro Blue is the wonderful colour made famous by Audi’s original fast estate, the RS2. Thus you’ll find it inside and outside this RS6, with the Nogaro Alcantara on the seats and door panels looking particularly fetching.

It’s joined inside by a fully suede steering wheel rim and plenty of carbon trim and numbered plaques, to remind you how special your RS6 is. Good job, when it costs 130,000 euros (about £115,000), a 12,000 euro rise on standard before you’ve taken it to ABT.
