Automotive publications rave about how well the Mercedes-Benz M-Class performs on the road. The versatile SUV comes standard with a potent V-6 engine. While the optional Bluetec diesel engine is a fuel-saver, the turbocharged V-6 engine increases the SUV’s towing capacity to 7,200 pounds. At the top of the lineup sits the turbocharged V-8 engine, which pounds out an aggressive 518 horsepower. A rugged off-road package is offered as well. When riding in the M-Class, everyone will have a surplus of legroom. An available Lane Tracking package provides you with an additional sense of security.
