Mercedes-Benz has continued to refine the M-Class SUV for 2011 by introducing a new, very efficient hybrid drivetrain. Though equipped with a relatively heavy, less-advanced nickel-metal-hydride battery pack, the ML450 Hybrid helps make this already-sophisticated SUV line a front-runner in the luxury utility race. With a unibody design, excellent road manners and a world-class suspension, the vehicle delivers all the comfort of a crossover with the capability of an SUV. With a respectable cargo area that delivers up to 29.4 cubic feet of storage and seating for five individuals, the 2011 Mercedes-Benz M-Class remains an excellent alternative family vehicle.
