MTM Supercharged Audi S4
German tuners MTM have given the Audi S4 and S5 Cabrio enough power to compete with their up-trimmed siblings. Through the use of their M-Cantronic ECU system, MTM has given the two cars – both powered by the 3.0 TFSI V6 engine – 430 horsepower, which is only 10 hp less than the stock Audi RS4′s V8 engine.
Along with the M-Cantronic system, MTM uses new exhaust components to help with power delivery. The MTM S4 is also equipped with bigger brakes and 8-piston calipers, a lowered suspension, and 19-inch Bimoto wheels.
430 horsepower get the MTM S4 from zero to 62 mph in 4.6 seconds with the 6-speed manual transmission, and can reach a top speed of 177 mph with the optional V-Cantronic system which removes the top speed limiter from the stock ECU.
The kit is not cheap, either. For both the M-Cantronic and V-Cantronic system producing 430 hp, the system costs $4,600 USD, another $6,183 for the exhaust system, and $6,046 for the wheels. The suspension tuning is $1,048, and the big brakes are $6,654, coming to a total of $24,531 for the MTM S4, plus the price of the car, if you don’t add any other options.
