Making 520hp at the wheels, this carefully modded Audi S6 might be one of the nicest sleepers on the road today.
The Audi S6 is not a car that attracts a lot of attention and perhaps this is a solid reason why some people prefer it over other, flashier opponents.
The 4.0-litre twin-turbo V8 is a very compact engine, allowing the latest Audis to offer a pointier front end in the handling department as the powerhouse is now sitting much closer to the axle than the previous generation models.
Not to mention the amazing soundtrack of it, provided by the aftermarket exhaust. These twin-turbos can really gain some serious numbers with just a few bits here and there.
Matt Farrah takes this 2015 Audi S6 for a quick drive on some hilly roads to see if the added power has managed to take away some of the friendliness these models are known for.
