The “old” G series AMG has undergone the greatest change in its history, while remaining true to its well-proven virtues. Unmistakable design features give the new AMG G63 its unique appearance: the boxy silhouette, the proud hood, external door hinges, round headlamps, mounted direction indicators, robust door handles, muscular protective strips with inserts in high-gloss black with a silver AMG emblem, the exposed spare wheel on the rear door with a stainless steel cover and three-dimensional Mercedes star.
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. This is available across a wide rev range between 2,500 and 3,500 rpm, and provides a sense of effortless superiority. The G63 completes a sprint from zero to 60 mph in just 4.4 seconds (est.), 0.9 seconds faster than the previous model. This dynamic performance is maintained up to the limited maximum speed of 137 mph, or 149 mph with the AMG Driver’s package.
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.
The new G63 performs even better when off-road, and on the road it is more dynamic and comfortable than its predecessor. The agile driving impression is substantially due to the suspension system, which has been completely redesigned by Mercedes-AMG and features coil springs all-round. For the first time the front axle has an independent, double wishbone suspension; a rigid axle with a five-link suspension is used at the rear. The components of the double-wishbone front suspension are directly mounted to the ladder-type frame without a subframe. The attachment points of the lower wishbone are positioned as far up as possible. This arrangement ensures good drivability both on and off the road. A strut tower brace, known as a suspension bridge, now connects the front strut towers, which increases the torsional rigidity of the ladder-type frame.
For the first time in the history of the Mercedes-AMG G-Class, the driving characteristics can be individualized at the touch of a finger with five on-road and three off-road driving modes. With the five AMG DYNAMIC SELECT on-road modes “Slippery,” “Comfort,” “Sport,” “Sport+” and “Individual,” the characteristics range from efficient and comfortable to very sporty. Key parameters such as the response of the engine, transmission, suspension and steering are modified in the process. Independently of the AMG DYNAMIC SELECT drive programs, the driver has the option of pressing the “M” button to switch directly to manual mode, in which gearshifts are executed exclusively using the shift paddles on the steering wheel. If required, the stages of the adaptive adjustable suspension can be selected as well. Three off-road modes – “Sand,” “Trail,” and “Rock” – are available when driving off the beaten track.
The new G63 has been given a completely newly designed, modern interior that echoes specific exterior features. The shape of the round headlamps is reflected in the side air vents, and in the shape of the indicators in the tweeters on the dashboard. Hallmarks of the G63 also include the grab handle in front of the front passenger and chrome-highlighted switches for the three differential locks.
The completely redesigned dashboard has analogue tubes as dial instruments as standard. Optionally the fully digital Widescreen Cockpit with virtual instruments directly in the driver’s field of vision and a central display above the center console can be ordered. The two 12.3-inch displays visually blend into a single unit beneath a shared glass cover. The driver is able to choose from three different views – “Classic,” “Sporty” and “Progressive” – and access the required information individually.
