Looking at it at the Monte Carlo's pier, one might be forgiven to think this
is an original S8, until he sees the three tell-tale letters testifying to this
saloon's special status. mtm, a discreet white on black, is to be discerned
forward of the rear wheel housing. Namely, a special Audi S8, one from the high
tech laboratory of mtm, a stone's throw from the Audi's headquarters in
Roland Mayer, an engineer and mtm GmbH's Managing Director, has specialized in upgrading series production Audis and numerous other types from the Volkswagen Group's extensive portfolio. Successfully so, because his creations win their laurels before the public's gaze, offer themselves up for international sporting comparison, set records and withstand critical media scrutiny of their quality in terms of technical precision, look and feel.
The same is true of the mtm S8 Biturbo. Instead of the series production 520 hp, the eight cylinder engine now boasts more than 650 hp at 5,950 rpm after mtm's engineers have worked their magic. Enough to accelerate the luxurious saloon from a standing start to 60 mph in less than four seconds. An impressive figure, as is the limited top speed of 182 mph (293 km/h). For the driver the penny actually drops throughout the acceleration process when the 590 lb-ft (800 Nm) of torque develops not as a curve but in a straight line: from 1,700 rpm to 5,500 rpm the power, transmitted via an eight-speed tiptronic transmission, relentlessly forces all the occupants back into their seats. 405 X 38 mm brake discs on the front axle hold this powerplay suitably in check; the brake calipers are production standard - front and rear.
