BMW M3 (cabriolet)

German tuning studio ATT "has pumped over" cabriolet BMW M3. Let's remind, the serial version of model is equipped with the 4-litre 8-cylinder engine power of 420HP, however this power insufficient has seemed to tuners and forced the motor.

At the expense of installation of the compressor and a new exhaust system, and also completion of block ECU masters ATT managed to "squeeze out" of the factory unit additional 80HP. Thus now power of the engine makes 500HP.
