Exceptionally quiet, extremely practical, and exceedingly comfortable, the Mercedes-Benz E-class wagon is the luxury SUV for car people. A 329-hp 3.0-liter twin-turbo V-6 drives all four wheels through a nine-speed automatic; a self-leveling air suspension keeps the ride smooth and steady. All modern amenities are present and accounted for, such as touchscreen infotainment, automated emergency braking, and adaptive cruise control with a semi-autonomous driving mode. Expect it in showrooms in early 2017.
