Most owners, I suspect, will prefer to drive Mercedes’s new missile by their flawed human selves. I can’t blame them. The supersedan’s 4.0-liter biturbo V-8, shared with the AMG GT supercar, pours out up to 450 kilowatts (603 horsepower). This Benz will hit 100 kilometers per hour (62 miles per hour) in a supercar-like 3.3 seconds, which is ridiculous for a sybaritic, all-wheel-drive midsize sedan.
Yet when it’s time to take a break from perspiring action, the new Drive Pilot system surrounds the Benz in radar beams that peer 250 meters ahead and 80 meters behind the car. They’re supplemented by separate 3D and 2D cameras that read lane markers and traffic ahead.
