With a 580-hp twin-turbo V10 derived from the Lamborghini Gallardo's mill, the Audi RS6 is hardly a candidate for improvements. It's a station wagon that outguns supercars, for crying out loud. But we had to figure that it would only be a matter of time until someone tried, and German tuning house MTM has stepped up to bat.

To give you an idea of what MTM's engineers are capable, with just a tweak of the ECU they've managed to boost output to 656 hp, dropping the 0-60 time down from an already outstanding 4.6 seconds to a scant 3.9. Throw in a stainless steel exhaust and a new air filter and presto! You've got 702 horses underhood. MTM is also offering some reserved carbon fiber aero bits, a new set of brakes, revised dampers and 21-inch wheels. We don't know what kind of world this is where you can get your hands on a 700 horsepower wagon, but we like it.
