The new Mercedes-Benz ML63 AMG showcases exceptional new technology. The AMG 5.5-liter V8 biturbo engine features spray-guided gasoline direct injection with piezo injectors, ECO stop/start system, an all-aluminum crankcase, four valves per cylinder with camshaft adjustment, air-to-water charge air cooling and efficient alternator management. With a displacement of 5461 cc, the eight-cylinder engine generates a maximum power output of 518 hp and 516 lb-ft of torque. Combined with the AMG Performance Package, these values rise to 550 hp and 560 lb-ft. This difference in power and torque results from an increase in the maximum charge pressure from 14.0 to 18.8 psi. Both variants of the ML63 AMG deliver sports-car performance. Acceleration from zero to 60 mph takes 4.7 seconds and 4.6 seconds respectively, while the top speed remains at 155 mph (electronically limited) and at 174 mph with the AMG Performance Package. With or without the AMG Performance Package, fuel economy remains unchanged. The AMG Performance Package also includes an engine cover in high-quality genuine carbon fiber, calipers painted in red and the AMG Performance steering wheel in Premium leather/DINAMICA.
Efficient and versatile - AMG SPEEDSHIFT PLUS 7-speed transmission
Power delivery to all four permanently driven wheels is via the AMG SPEEDSHIFT PLUS 7-speed automatic transmission. Featuring three driving programs and a rev-matching function for downshifting, this outstanding gearbox offers amazingly broad scope. In "Controlled Efficiency" mode (C) the ECO stop/start function is active, shutting down the eight-cylinder engine when the vehicle is stationary. The "C" mode also delivers smoother acceleration and transmission characteristics with comfortable, earlier gear changes. Pulling away in this mode usually begins in second gear. A green "ECO" symbol in the AMG instrument cluster indicates that the ECO stop/start function is active.
In the Sport (S) and Manual (M) driving programs the ECO stop/start function is inactive and the engine/transmission characteristics are far more agile. A brief and precisely defined retardation of ignition and injection during upshift at full load also delivers shorter shift times.
Enhanced efficiency and driving dynamics
For added efficiency, the AMG SPEEDSHIFT PLUS 7-speed automatic transmission incorporates a new fuel-efficient torque converter, bearings designed for reduced friction loss and a thermal management system for the transmission oil. Axle gears with minimal friction loss, electronic steering, an optimized belt drive, on-demand control of all accessory drives and an intelligent lightweight design also help to reduce fuel consumption even further. The new ML63 AMG is 99 pounds lighter than its predecessor - despite the increase in power and the more comprehensive range of standard equipment.
As on the previous model, Mercedes-AMG uses a dedicated transfer case for the 4MATIC permanent all-wheel drive, which distributes engine power at a ratio of 40:60 to the front and rear axle for improved dynamic characteristics. Furthermore, the AMG sports suspension with AIRMATIC Air Suspension, independent damper struts, automatic level control and Adaptive Damping System (ADS) is combined for the first time with the ACTIVE CURVE SYSTEM for active roll stabilization. This system, which is standard equipment on the Mercedes-Benz ML63 AMG, features active stabilizers on the front and rear axles to compensate for body roll during cornering. In addition to enhanced agility and driving fun, the system also improves stability for added safety, especially at higher speeds.
Roll stabilization, damping and suspension adapt instantaneously to the prevailing driving situation, offering optimum ride comfort and maximum stability. The driver can choose at the touch of a button between the three driving modes "Comfort", "Sport" and "Manual". The air suspension system is speed-sensitive, lowering the body at higher speeds to minimize drag while increasing stability.
The AMG elastokinematics on the front axle and more robust stabilizer bar on the rear axle improve steering precision. The enhanced drivetrain provides optimum power transmission and hallmark Mercedes reliability. The standard 4ETS electronic traction control system provides the best possible grip in slippery conditions.
AMG speed-sensitive sports steering, AMG high-performance braking system
Electromechanical AMG speed-sensitive sports steering features speed-based power assistance and helps to save fuel because it only consumes energy when the driver actually moves the steering wheel. The Mercedes-Benz ML63 AMG comes with 20inch 5-spoke alloy wheels painted in titanium grey with a high-gloss finish and fitted with 265/45 R 20 high-performance tires. Also available are optional 295/35 R 21 tires on 21-inch AMG alloy wheels. The AMG high-performance braking system provides the shortest possible braking distances and high fade resistance, featuring ventilated and perforated brake discs at all four corners. Sizes are 15.4" x 1.4" (front) and 13.6" x 1.0" (rear).
AMG styling with trim in silver chrome matte finish
The design of the new ML63 AMG exudes self-confidence, athleticism and power. AMG styling dominates the front view. Beneath the radiator grille with louvers in high-gloss paint finish and the prominent Mercedes star is a large cooling air intake. Together with the two air intakes, the central radiator grille provides effective airflow to the radiator, as well as the engine oil, charge air and transmission oil coolers. Fitted at the bottom of the AMG front skirt is a trim strip in matte silver chrome, which lends breadth to the front end while blending with the frames of the daytime running lights and into the side air intakes. Bixenon headlamps offer a premium and and exclusive look in combination with the standard Lighting Package. The AMG front skirt is integrated into the distinctive front fenders, which are 0.4 inches wider on either side to accommodate the large AMG alloy wheels. Prominent, fender-mounted "V8 BITURBO" badges identify the vehicle as the top AMG model in the M-Class. AMG illuminated sill panels feature dynamic styling and establish a visual link between the front and rear of the vehicle.
