MTM has chosen a German diesel engine for their latest aftermarket program. The package consists of adding significant power to the VW Group's 4.2-liter TDI V8 powerplant. The diesel engine, in addition to coming on the Audi A8, also is available in the VW Touareg and the Audi Q7. Tuning
programs for diesel engines are relatively rare, so MTM's latest product absolutely piques the interest. Out of the factory, the Volkswagen diesel puts out 350hp and 591 lb-ft of torque.
