Mercedes-Benz CLS550 Coupe

Engine

5,461-cc DOHC 32-valve V-8. Aluminum-alloy cylinder block. Aluminum-alloy heads.

Transmission

Electronically controlled shifting. Driver-adaptive programming adjusts shift points to the driver's current driving style. Touch Shift allows driver to manually downshift and allows upshifts by nudging the shift lever left or right from the Drive position. Shift into Optimum Gear programming allows one-touch selection of the best gear for maximum acceleration or engine braking by holding the shift lever to the left of Drive for one second. Driver-selectable Comfort mode starts vehicle moving in 2nd gear or 2nd Reverse gear, and upshifts at lower rpm, to help improve control on slippery surfaces.

Traction Control & Stability Systems

Electronic Stability Program (ESP®) ESP compares the driver's intended course, via steering and braking inputs, to the vehicle's response, via lateral acceleration, rotation (yaw), and individual wheel speeds. ESP then brakes individual front or rear wheels and/or reduces excess engine power as needed to help correct understeer (plowing) or oversteer (fishtailing). ESP also integrates all-speed traction control, which senses drive-wheel slip under acceleration and individually the slipping wheel or wheels, and/or reduces excess engine power, until control is regained.
