G-POWER makes the "old M3" quicker than the "new M3"

450 hp for the BMW M3 E46 and Z4M, that’s quiet impressive. The G-POWER SK I supercharger system provides the 3.2 l straight cylinder engine from the BMW M GmbH with the necessary boost to push the output from standard 343 hp/365 Nm to awesome 450 hp/450 Nm.
