Adapted from the engine in the automaker’s S-Class sedan and SL-Class roadster, the all-aluminum, 5.0-liter V-8 in the G500 produces 292 horsepower and 336 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 a Low range, which is fully synchronized for shift-on-the-fly operation at up to 15 mph. Mercedes-Benz’s Electronic Stability Program is also installed.
