Under the Hood

Adapted from the engine in the S-Class sedan and SL-Class roadster, the all-aluminum, 5.0-liter V-8 produces 300 horsepower and 330 pounds-feet of torque. Each engine cylinder uses a three-valve, twin-spark setup. An electronically controlled five-speed-automatic transmission sends the power to a full-time four-wheel-drive system with Low range, which is fully synchronized for “shift on the fly” operation at up to 15 mph. Mercedes-Benz’s lateral-skid control system, called Electronic Stability Program (ESP), also is installed.
