Mercedes-Benz 4MATIC AWD is a fantastic integration of technology. It is not four-wheel drive with a shot of espresso to ramp it up a bit. Think of it kind of like your body's core muscle group. Your core acts as a lever and guides supplementary muscles to jump in and help when you pick something up off the floor. 4MATIC AWD works as your core muscle group within your Mercedes-Benz. Continually monitoring the system, it sends extra help to the areas of the drivetrain as needed. If you overcorrect while taking a turn too fast, 4MATIC AWD has already stepped in to balance the weight of your vehicle.
