Motoren Technik Mayer is a German tuner active since 1985. Less well known than ABT for example, MTM is nevertheless an active company with many projects. Like in 2004 with this RS 6 SW modified by the little hands of MTM. The station wagon comes out of its trip to the Wettstetten workshops with a more aggressive look and above all an engine pumped up to 580hp, 120 more than the original version!
