Tuner company M&D Exclusive Car Design has turned its attention to the pre-facelift Audi S7 Sportback, giving it a host of visual and mechanical modifications. As standard, the 2013 Audi S7 produces 414 hp and 550 Nm of torque from its 4.0 litre, turbocharged V8; after modifications, the M&D-fettled product pumps out 690 hp and 950 Nm of torque.

That output makes its a more potent machine than Audi’s most powerful factory standard effort, the current RS7 Sportback, which produces 597 hp and 700 Nm of torque. To get there, the powerplant has received an upgraded air intake, improved turbocharger, a sports exhaust system with larger downpipes, high flow catalytic converters, and a customised ECU.

To some, a tuner effort isn’t complete without a revamped exterior, and on that front M&D is happy to oblige. A Prior Design widebody kit for the modified S7 includes a new front bumper with lip spoiler and larger air intakes, deeper side skirts, while a new rear bumper features a larger rear diffuser; broader fenders front and rear accentuate the areas around the wheels, while the RS7 contributes its updated tail lights and radiator grille to the M&D car.

The wheels themselves are Rennen Forged 21-inch, matte black spoked wheels with gloss black barrels, while the dark theme is carried on by the dark tint on the rear window and the rear door windows. Contrasting with those is a set of foil designs inspired by Audi’s racing livery, with the pearl effect glacier white paintwork forming the base for the black, read and grey graphics.

On the inside, M&D exercised restraint with the S7’s interior, choosing instead to apply some low-key changes. The car gains a flat-bottomed steering wheel from the RS7, while the infotainment software has been modified so that the S7’s occupants can watch TV whilst on the move, as well as access menus that were previously hidden.

It’s sure to turn heads on the road; what do you think of M&D’s take on the Sportback?
