Safety has for decades been one of Mercedes-Benz's top selling points, along with design attributes, features, and engineering that goes well beyond requirements and expectations. That's still the case with the 2013 M Class.
Advanced safety features are what pushes the M Class from being merely a safe pick to one that will help keep you out of trouble when the unexpected happens. Its available Distronic Plus adaptive cruise control is one of the most sophisticated and unobtrusive systems on any vehicle—capable of coming to a full stop with traffic and restarting, and potentially reducing fatigue. Pre-Safe, Lane Keeping Assist, and Blind Spot Assist (all optional) all provide the sort of alerts that might make a split-second difference.
Attention Assist, which takes tabs on driving style to help identify the signs of drowsy driving—triggering a coffee-cup icon and some warning beeps—is now a standard feature on all M Class models.
The M Class gets top 'good' ratings in all crash-test categories from the Insurance Institute for Highway Safety (IIHS), along with the group's Top Safety Pick nod.
