Mercedes-Benz ML63 AMG
The 2012 Mercedes-Benz ML63 AMG unites efficiency and performance, exclusivity and an outstanding driving experience. The estimated combined fuel economy for the high-performance SUV is 16 mpg, marking a 33-percent improvement over its predecessor. The basis for the excellent fuel economy and performance is the AMG 5.5-liter V8 biturbo engine with an output of 518 hp and torque of 516 lb-ft, representing an increase of 15 hp and 44 lb-ft over its predecessor. The available AMG Performance Package boosts the V8 engine's power output to 550 hp and its maximum torque to 560 lb-ft. The newly developed ACTIVE CURVE SYSTEM for active roll stabilization, the AMG design and the broad scope of standard equipment and appointments produce a highly attractive overall package.
The new 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.
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.
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.
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 ML63 AMG comes with 20- inch 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).
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.
Sporty character and premium quality define the interior of the high-performance SUV from AMG. This is evident in the standard designo premium leather AMG power sports seats offering excellent lateral support, as well as the four-spoke AMG Performance steering wheel. The latter ensures excellent vehicle control with perforated leather grips, aluminum shift paddles and a rim flattened on the bottom. Aluminum trim elements and the piano-lacquer retractable cover in the center console highlight the interior's dynamic and exclusive flair. The standard designo premium leather upholstery includes contrasting double topstitching and AMG badges in the backrests of the front seats and the outer rear seats. Dashboard, armrests and door trim are also finished in designo premium leather with double topstitching.
