The new 2019 Mercedes-AMG G63 has undergone the greatest change in its history – while remaining true to its well-proven virtues.

The G63 underpins its unique position among performance off-road  vehicles  with  a powerful drive system, an AMG-developed  suspension, AMG-specific transmission modes and a new interior  with  optimal  widescreen  cockpit.

The basis for the hallmark AMG Driving Performance both on and off road is provided by the 577 hp handcrafted AMG  4.0-liter  V8  biturbo  engine, rear- biased all-wheel drive (40:60) with three  differential  locks,  extremely  fast- shifting 9-speed automatic transmission, double wishbone independent front suspension and adaptive adjustable damping. The reinterpretation of the unmistakable design creates strong highlights with  the  AMG-specific  radiator grille, flared wheel arches, striking side  pipes on the exhaust  system  and  wheels  up to 22-inches in diameter.

Proven to be powerful: the handcrafted AMG 4.0-liter V8 biturbo engine

The handcrafted AMG 4.0-liter V8 biturbo engine now also replaces the previous 5.5-liter V8 biturbo engine in the G63. It generates 577 hp in this model, and delivers a maximum torque of 627 lb-ft.

The two turbochargers are not positioned on the outside of the cylinder banks, but inside the cylinder “V.” Advantages: a compact engine design, spontaneous response of the turbochargers and low exhaust emissions thanks to optimal airflow to the near-engine catalysts. The eight-cylinder delivers its power with muscular torque in all engine speed ranges, combined with maximum  efficiency for low fuel consumption and emission figures.

Other engine features include modified pistons, optimized intercooling and extensive software upgrades. Spray-guided direct gasoline injection with piezo injectors, an all-aluminum crankcase, four-valve per cylinder design with camshaft adjustment, air-water intercooling, alternator management, ECO start/stop function and gliding mode have all been retained.

AMG Cylinder Management cylinder deactivation system

For more efficiency, Mercedes-AMG has equipped the V8 engine in the G63 with the AMG Cylinder Management cylinder deactivation system. In the partial-load range, cylinders two, three, five and eight are deactivated, which significantly lowers the fuel consumption.

When the driver has selected the “Comfort” transmission driving mode, the cylinder deactivation system is available in the wide engine speed range from 1,000 to 3,250 rpm. The AMG main menu on the instrument cluster informs the driver whether the cylinder deactivation system is in use and whether the engine is presently operating in the partial or full-load range.

The wide ratio spread allows a choice of a very sporty or a very comfortable and efficient driving experience. In all transmission modes the G63 moves off in first gear so as to ensure a dynamic sprint from a standstill whenever required. The DIRECT SELECT lever has been repositioned as a steering column stalk.

“Manual” mode can be selected using a separate switch. The gear changes are based on the selected transmission mode, and the driver can now change gear using the paddles on the steering wheel. Moreover, the transmission stays in the selected gear and does not automatically shift up when the engine speed reaches the limit.
