MTM is not known for its restraint - it is, after all, the same company that fitted two enginess into an Audi Tt to set a speed record at Nardo. Its engineers have now taken the tuner's brand of high-power, no-holds-barred modification to the internal workings of thd new Audi S4 Avant, already one of the most potent of the Audi S cars.
Just on the market, MTM has injected the new 3.0L supercharged S4 with more power and driving dynamics. The V6 engine in the standard version comes with a respectable 333hp (248kW) on tap, but it really comes alive after the MTM treatment. With this package the modified S4 is able to challenge the bigger RS models with their V8 engines. A total of 430hp (320kW) and 380lb-ft (515Nm) of torque was measured on the MTM dynamometer.
With drive sent to all four whells via a six-speed manual gearbox and quattro AWD, the modified S4 will sprint from 0-100km/h in just 4.7 seconds-0.4 seconds faster than the stock version.
Beside improved performance, MTM also offers for the S4 a custom exhaust kit, bimoto wheels (19 and 21in) and MTM height adjustable suspension and performance brakes. This latter element comes with 380mm discs and 8-piston calipers.
