  This tester didn't have the new Magic Body Control system, which essentially uses stereo cameras to scan the road for imperfections to prepare the suspension system for those upcoming bumps. That said, the "standard" Airmatic suspension keeps things nice and smooth, even with our tester's large and sharp-looking 20-inch wheels. One cool piece of tech our tester did have was the Distronic Plus with Steering Assist. Distronic has been around for years and is Benz's term for the advanced adaptive cruise control system that has the ability to fully stop the car and accelerate again (think stop-and-go traffic). The Steering Assist is new and is aptly named – it will take over the helm and keep the car within your lane, and will keep doing so as long as you don't encounter any major bends in the road. It does the job, though it takes getting used to watching the steering wheel move on its own. It will also alert you every 10 seconds to keep your hands on the wheel, only because fully autonomous cars aren't completely legal (yet).
