#AMG 2019 Mercedes-AMG G 63 585 hp @ Driving Scenes

With the new Mercedes-AMG G63, the Mercedes-AMG G-Class 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 the powerful drive system, the newly developed AMG RIDE CONTROL suspension, the AMG-specific transmission modes and the new interior with optimal widescreen cockpit. The basis for the hallmark AMG Driving Performance both on and off metalled roads is provided by the 430 kW (585 hp) 4.0-litre V8 biturbo engine, the rear-biased all-wheel drive (40:60) with three differential locks, the extremely fast-shifting 9-speed automatic transmission, the double wishbone independent front suspension and the 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 the up to 22-inch wheels.
"The new AMG G63 brings driving performance to the segment of unadulterated off-road vehicles in unexpected form. It was important for us to tie in with the original character on account of the cult status the G63 enjoys with our customers and fans. The vehicle has nevertheless reached a completely new dimension in terms of technology with the 4.0-litre V8 biturbo engine as well as in combination with the off-road characteristics, the agility and the vehicle dynamics achieved", explains Tobias Moers, CEO of Mercedes-AMG GmbH. "This applies to the entire G-C lass model series. Mercedes-AMG is responsible for their suspension and chassis development as well as V8 competence."
Proven to be powerful: the AMG 4.0-litre V8 biturbo engine
The AMG 4.0-litre V8 biturbo engine now also replaces the previous 5.5-litre V8 biturbo engine in the G63. It generates 430 kW (585 hp) in this model, and delivers a maximum torque of 850 Nm. This is available across a wide rev range between 2.500 and 3.500 rpm, and provides a sense of effortless superiority. It absolves a sprint from zero to 100 km/h in 4.5 seconds. This dynamic performance is maintained up to the limited maximum speed of 220 km/h, or 240 km/h 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.
Two twin scroll turbochargers are used for optimal response. The housing is divided into two parallel flow channels. Combined with two separate exhaust ducts in the exhaust manifold, this makes it possible to control the exhaust gases on the turbine wheel separately. The exhaust gas from the first and fourth cylinders of the cylinder bank is fed into one duct, that from the second and third cylinders to the other duct. The aim is to prevent the individual cylinders from having mutually adverse effects on the gas cycle. This reduces the exhaust gas back pressure and improves gas exchange. The results are increased output by virtue of improved cylinder charging with fresh mixture, more torque at low revs and very fast response times.
Other engine features include modified pistons, optimised intercooling and extensive software upgrades. Spray-guided direct petrol injection with piezo injectors, the all-aluminium crankcase, the four-valve per cylinder design with camshaft adjustment, air-water intercooling, alternator management, the ECO start/stop function and the 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. The combined fuel consumption is 13.2 l/100 km, and the combined CO2 emissions 299 g/km.
When the driver has selected the "Comfort" transmission driving mode, the cylinder deactivation system is available in the wide engine speed range from 1000 to 3250 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 transition from four to eight-cylinder operation is fast and imperceptible, so that the passengers do not experience any loss of comfort whatsoever.
