The new high-performance SUV, the Mercedes-Benz GL 63 AMG, combines compelling technologies with an extensive range of standard equipment and pure ride comfort for up to seven passengers. Effortless superiority comes courtesy of the AMG 5.5-litre V8 biturbo engine, which develops a peak output of 410 kW (557 hp) and maximum torque of 760 Nm. The AMG RIDE CONTROL sports suspension with ACTIVE CURVE SYSTEM roll stabilisation provides high-level driving dynamics and the comfort one would expect from the Mercedes brand.
The AMG M 157 eight-cylinder engine features an innovative, high-tech power package including spray-guided direct petrol injection, piezo injectors, biturbo charging, air/water intercooling, all-aluminium crankcase, a four-valve-per-cylinder design with variable camshaft adjustment, plus alternator management and the ECO start/stop system.
Power is transmitted to all four permanently driven wheels by the AMG SPEEDSHIFT PLUS 7G-TRONIC. Featuring three modes and an automatic double-declutching function for downshifting, this seven-speed automatic transmission offers a fascinatingly broad scope of variability. In “Controlled Efficiency” (C) mode the ECO start/stop function is active, shutting down the eight-cylinder engine as soon as the vehicle comes to a standstill. “C” also stands for a gentle accelerator and transmission characteristic with early gear changes; start-up generally takes place in second gear here. A green “ECO” symbol in the AMG instrument cluster indicates to the driver that the ECO start/stop function is active.
In the Sport (S) and Manual (M) driving programmes the ECO start/stop function is inactive and the engine-transmission combination displays far greater agility with more spontaneous responses. A brief and exactly defined retardation of ignition and injection during upshifting at full load additionally provides for shorter shift times and an acoustic experience.
Electromechanical AMG speed-sensitive sports steering features variable power assistance which responds in accordance with the chosen suspension mode. It also helps to save fuel, as the steering assist function only requires energy when the driver actually moves the steering wheel. The GL 63 AMG comes as standard with 5-spoke light-alloy wheels in format 10 x 21, painted titanium grey and with a high-sheen finish, fitted with tyres in size 295/40 R 21. The AMG high-performance braking system provides for the shortest possible braking distances and high fade resistance with ventilated and perforated brake discs all-round in size 390 x 36 millimetres (front) and 345 x 26 millimetres (rear).
The AMG front apron elegantly merges into the exclusive wheel-arch flaring. In order to accommodate the large 53.3 cm (21-inch) AMG light-alloy wheels with the wide-base 295 tyres, the flaring widens the vehicle by 22 millimetres on each side. From the side, observers will notice the V8 BITURBO logos on the wings and illuminated running boards with an aluminium finish. The rear wheel-arch flaring blends into the AMG rear apron which is again adorned with a striking trim insert in matt silver chrome and the suggestion of black air openings. Creating both a visual and acoustic highlight are the two chrome-plated, exposed twin tailpipes of the AMG sports exhaust system.
The market launch of the new Mercedes-Benz GL 63 AMG is scheduled for November 2012.
