For 2013, a new Off-Road package offers a 2-stage transfer case, Airmatic adjustable suspension, locking differential and six selectable driving programs. The ML350 now offers a rear-drive model, while new massaging front seats with comfort headrests join the options list. New standard equipment includes the mbrace2 telematics system and Collision Prevention Assist.
The newest Mercedes-Benz M-Class SUV is a far cry from the original model. Whereas the first M-Class featured body-on-frame construction, the new ML employs a unit-body design. This creates a stiffer chassis, which helps eliminate rattles and vibration as well as quiet the interior; the design also allows for a more sophisticated suspension, yielding better handling and a more civilized ride. Although it can seat five, the ML is most comfortable with four passengers. It offers a modest cargo bay of 29.4 cubic feet, which is more space than an Infiniti FX35, but less than offered by the Acura MDX. For 2007, the M-Class offers a diesel engine option, a feature unique to this class.
