Mercedes-Benz launches M63 AMG

A conundrum of sorts

TopGear.com.ph Philippine Car News - Mercedes-Benz launches M63 AMG

Just five months after Mercedes-Benz launched the all-new M-Class to the world, the German carmaker is now bringing its high-performance variant to the public: the M63 AMG.

With its combined New European Driving Cycle (NEDC) fuel consumption of 11.8 liters of fuel for every 100 kilometers (a mileage of 8.475 kilometers per liter), the M63 AMG undercuts its predecessor by 4.7 liters or 28 percent.

Powering the M63 AMG is a 5.5-liter biturbo V8 direct petrol injection engine that produces 517hp and 700Nm of torque, marking an increase of 15hp and 70Nm of twist over its predecessor. With the optional AMG Performance Package, the M63 AMG's output is bumped to 550hp and 760Nm.

Though the all-new M63 AMG is only 0.1 second faster than the model it replaces and it has an eletronically-limited top speed of 250kph, the use of the optional AMG Performance package reportedly doesn't negate the car's fuel consumption level of 11.8 liters-per-100-kilometers and limits the carbon dioxide emission to 276g per kilometer.

Aiding the car with its outstanding fuel mileage is its ECO start/stop system, lightweight all-aluminum crankcase, four valves per cylinder with camshaft adjustment, air-water charge air-cooling and generator management, for example.

Putting the all-new M63 AMG’s power down to all four wheels is the AMG SpeedShift Plus 7G-Tronic system. Featuring three driving programs and an automatic double-declutching function for downshifting, this seven-speed automatic transmission offers a broad scope of variability.

In Controlled Efficiency mode (C) the ECO start/stop function is active, shutting down the eight-cylinder engine when the vehicle is stationary. C also stands for a gentle accelerator and transmission characteristic with comfortable and early gear changes, with start-up generally taking place in second gear. 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 programs, the ECO start/stop function is inactive and the engine-transmission combination displays far greater agility. A brief and exactly defined retardation of ignition and injection during upshifting at full load additionally provides for shorter shift times.

In terms of styling, AMG's influence can be seen under the radiator grille with louvers in high-gloss paint finish  and the large cooling air intake where the number plate is positioned. Together with the two outer air intakes, the central radiator grille provides for an effective flow of air to the water, engine oil, charge air and transmission oil coolers. Fitted at the bottom of the AMG front apron is a trim strip in matte silver chrome to give it a wider appearance while the front apron is integrated with wider front fenders to accommodate the large AMG light-alloy wheels. V8 BITURBO logos identify the vehicle as the top AMG model in the M-Class while the stainless steel door sills establish a visual link between the front and rear of the vehicle.

Rounding out the exterior upgrades are the AMG rear apron highlighting the black air outlet openings to emphasize further the vehicle's width. The two-set AMG sports exhaust system with its chrome twin tailpipes give the M63 AMG a distinctive full eight-cylinder sound.

"Like its predecessors, the new ML 63 AMG sets new standards in terms of performance, exclusivity and a superlative driving experience--plus the efficiency factor, which is acquiring ever greater emphasis at Mercedes-AMG," said Ola Källenius, chairman of Mercedes-AMG GmbH. "As the inventor of the high-performance SUV, we remain true to the philosophy which we introduced in 1999 with the M55 AMG and continued in 2005 with the M63 AMG."
