The best way to enjoy any trip is if you know that your car will keep you safe. The M-Class is a prime example. Alongside the dynamic handling systems and other safety features such as airbags, the NECK-PRO head restraints (crash-responsive in the front seats) and the restraint systems, the self-supporting body further enhances the safety of the M-Class. Its high-strength passenger cell is protected by the energy-absorbing front and rear structures.
