Since its inception, the M-Class has redefined what an SUV can be, with a legacy of groundbreaking safety and earth-embracing performance. For 2012, it once again shows that even on a familiar road, you can still blaze an exciting new trail.

Smooth, strong and surprisingly sensibleWith your choice of a new-generation 302-hp gasoline V-6 or a torque-rich yet fuel-stingy 240-hp clean-diesel BlueTEC V-6, the rewards of perfor- mance are yours on demand. Channeled through a paddle-shifted 7-speed automatic transmission, the torrential output of either engine is delivered with instant response and enduring efficiency.

Unswayed by the prospect of towingWith a generous 7,200-lb towing capacity when outfitted with optional hitch, the M-Class pulls a trailer with confidence. Whenever you're towing, standard Trailer Stability Assist acts decisively to rein in trailer sway, helping you keep your worries behind you.

A stimulating sanctuary for the sensesFrom the broad swaths of sustainably forested wood trim to the impec- cable stitching of the hand-fitted upholstery, every surface of the M-Class cabin reflects a deep tradition of caring craftsmanship and attention to your senses - of touch, of good taste and of well-being.

User-friendly innovations keep you in touchA large, high-resolution color screen sits high in the dash. An elegant central controller falls naturally to your hand. Together they offer intuitive access to a suite of advanced technology, from standard Bluetooth to available navigation and countless audio options, that is both easy to master and eager to help you feel at peace with your world.

Wholly immersive, nearly endless listening choicesWith standard USB and AUX jacks and Bluetooth audio streaming, along with optional iPod integration, SiriusXM Satellite Radio, HD Radio™ stations and a 10GB in-dash Music Register, you're more likely to run out of roads than music in the M-Class. An available 14-speaker harman/kardon LOGIC7 system brings it all to you with 830 watts of digital surround sound.

Innovative options help keep you on trackOptional DISTRONIC PLUS active cruise control automatically slows down or stops the vehicle in response to car traffic ahead. Its PRE-SAFE® Brake feature can sense an impending collision and apply full braking. Optional Blind Spot Assist and Lane Keeping Assist can help alert you to unseen vehicles in the next lane, help warn you of drifting out of lane, and with available active technology, help steer the vehicle back if you disregard the alerts.

Luxury begins where our hands finishStandard appointments in the M-Class include the rich glow of Eucalyptus wood trim and the enduring comfort of supple MB-Tex upholstery. For an elevated sense of indulgence, soft full-grain leather seating and the warm grain of Burl Walnut wood are optional. Either way, the hand-fitted upholstery and hand-finished wood reflect a deep tradition of finely tailored luxury.
