Four-wheel Drive
Four-wheel drive (4MATIC) is optional on models with 4-cylinder diesel engines. In normal operation the system transfers driving power in a 35:65 split between the front and rear axles. The 4MATIC system does not have mechanical differential locks, but an electronic traction system (4ETS). If one or more wheels loses traction on a slippery surface, the system applies brief pulses of brake pressure to the spinning wheels thus increasing torque to wheels with good grip.
Vehicles with four-wheel drive have a higher ride height, which increases approach, departure and breakover angles (20°/28°/19° respectively, versus 14°/22°/14° in conventional rear-wheel-drive models). The all-wheel drive adds 80 kg to the total weight of the vehicle.

Famous quotes containing the word drive:
“Signal smokes, war drums, feathered bonnets against the western sky. New messiahs, young leaders are ready to hurl the finest light cavalry in the world against Fort Stark. In the Kiowa village, the beat of drums echoes in the pulsebeat of the young braves. Fighters under a common banner, old quarrels forgotten, Comanche rides with Arapaho, Apache with Cheyenne. All chant of war. War to drive the white man forever from the red mans hunting ground.”
—Frank S. Nugent (19081965)
