Displacement: 3,982 cc
Output: 577 hp at 6,000 rpm
Peak torque: 627 lb-ft. at 2,500-3,500 rpm
Drive system: AMG Performance 4MATIC all-wheel drive with rear-biased torque distribution of 40:60
Transmission: AMG SPEEDSHIFT TCT 9G
Acceleration 0-60 mph: 4.4 s (est.)
Top speed: 137 mph, 149 mph (Driver’s package)
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.
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, 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.
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 transition from four to eight-cylinder operation is fast and imperceptible, so that the passengers do not experience any loss of comfort whatsoever.
