Up until now, there has never been a proper AMG version of the high-and-mighty Mercedes-Benz GL-Class. That all changes for the 2013 model year, as the automaker has just released the full slate of details about the upcoming GL63 AMG, set to arrive in North American showrooms in the first quarter of next year.
Cool as this GL63 may be, the upcoming G63 AMG (and not-for-U.S. G65 AMG) indeed win in the absolute awesomeness department.
The GL63 AMG formula is simple: take the new-for-2013 GL-Class and add Mercedes' potent 5.5-litre twin-turbo V8 engine. Here, the fire-breathing eight-pot produces 550 horsepower and 560 pound-feet of torque, meaning the big, all-wheel-drive SUV can sprint to 60 miles per hour (96 kilometres per hour) in just 4.9 seconds on its way to an electronically limited top speed of 250 km/h (155 mph). Start/stop is standard with this engine, and all that grunt is routed to the ground via Merc's seven-speed AMG Speedshift transmission.
Visual cues like more pronounced front air vents topped with LED running lamps set the GL63 apart from its lesser kin, as do the aluminum trim on the lower front fascia and aggressive-looking 21-inch five-spoke wheels that hide new red brake calipers. As you would expect, the interior is fitted with sporty upgrades like a new steering wheel, AMG sport seats and leather-wrapped everything.
Pricing has yet to be announced, though we fully expect it to command well over US$100,000. Scroll down for the full details in Merc's press blast.

The perfect balance of performance and style
Montvale – Luxury and refinement, distinctive design, outstanding safety and classic Mercedes dynamics – the new GL63 AMG high-performance SUV combines the latest technology with an extensive array of standard equipment and perfect comfort for up to seven passengers. Exceptional refinement comes courtesy of the AMG 5.5-liter V8 biturbo engine with a peak output of 550 hp and maximum torque of 560 lb-ft. The AMG RIDE CONTROL sports suspension with ACTIVE CURVE SYSTEM delivers compelling dynamics and classic Mercedes handling.
The MY 2013 GL350 BlueTEC, GL450 and GL550 arrive in U.S. dealerships in September 2012. The MY2013 GL63 AMG is expected arrive at U.S. Mercedes-Benz dealerships in the first quarter of 2013.
Ola Källenius, CEO of Mercedes-AMG GmbH: "With the new GL63 AMG, our range of performance-oriented SUVs is now complete. Alongside the outstandingly versatile ML63 AMG and the recently launched G63 AMG (U.S. debut in August) and G65 AMG (n/a U.S.), the GL63 AMG sets clear accents in the fields of dynamics and style. The GL63 AMG combines the first-class comfort of the S-Class with the performance of an AMG sports sedan and is utterly unique in its segment."
The AMG 5.5-liter V8 biturbo engine delivers the perfect prerequisites for a refined ride and performance that is typically AMG. One glance at the technical data delivers all the evidence you need. The peak output of 550 hp and maximum torque of 560 lb-ft delivers absolutely first-class performance. The GL63 AMG accelerates from 0 to 60 mph in 4.9* seconds, while the top speed stands at 155 mph (electronically limited).
The AMG eight-cylinder with the acronym M157 is equipped with an innovative package of high-tech features that includes spray-guided gasoline direct injection, piezo injectors, bi-turbocharging, air-water intercooler, a fully aluminum crankcase, four-valve technology with variable camshafts and alternator management, plus the ECO stop/start system.
An overview of the key data:
Displacement: 5461 cm3
Bore x stroke: 98.0 x 90.5 mm
Compression ratio: 10.0 : 1
Power: 550 hp @ 5250-5750 rpm
Max. torque: 560 lb-ft @ 2000-5000 rpm
Engine weight (dry): 450 lbs
Acceleration 0-100 km/h: 4.9 s**
Top speed: 155 mph*
Power delivery to all four permanently driven wheels is handled by the AMG SPEEDSHIFT 7-Speed automatic transmission. Equipped with three modes and an automatic double declutching function for downshifting, the seven-speed automatic offers an impressive degree of versatility. The ECO stop/start function is active in the Controlled Efficiency mode (C) and switches off the eight-cylinder engine as soon as the vehicle comes to a standstill. "C" also comes with a milder throttle and transmission setup with early gearshift. Pulling away generally takes place in second gear. A green "ECO" symbol in the AMG instrument cluster advises the driver that the ECO start/stop function is active.
In the Sport (S) and manual (M) modes, not only is the ECO stop/start function disabled, the engine/transmission combination also has more spontaneous reactions for a considerably more agile feel. In these modes, the brief and precisely defined retardation of ignition and injection during upshift under full load delivers faster shift times and a thrilling acoustic effect.
Greater efficiency and performance
For greater efficiency, the AMG SPEEDSHIFT 7-Speed automatic transmission is equipped with a highly efficient torque converter with centrifugal pendulum vibration absorber, friction-reduced bearings and transmission oil temperature management. Also contributing to reduced fuel consumption are friction-minimized axle drives, the electromechanical AMG speed-sensitive sports steering, optimized belt drive and on-demand control of all auxiliary units and pumps.
Mercedes-AMG uses a standalone transfer box for the 4MATIC permanent all-wheel drive that enhances the dynamic characteristics by splitting the drive 40:60 between the front and rear axles. Furthermore, the AMG RIDE CONTROL sports suspension with AIRMATIC package, consisting of air suspension, special struts, automatic self-leveling function and Adaptive Damping System (ADS), is combined with the ACTIVE CURVE SYSTEM. This is standard equipment and has been specifically adapted by AMG. It incorporates active anti-roll bars on the front and rear axles that reduce bodyshell roll angle under cornering for enhanced agility and driving pleasure. At the same time, the ACTIVE CURVE SYSTEM raises stability and thus safety, especially at high speeds.
Roll stabilization, springs and damping adapt automatically to the prevailing driving conditions and offer excellent ride characteristics, as well as exceptionally high stability. At the touch of a button, the GL63 AMG driver can choose between two suspension modes "Comfort" and "Sport". The full air suspension system is speed sensitive and lowers the bodyshell at higher speeds to minimize drag, while increasing stability.
The AMG-specific elastokinematics on the front axle and the stiffer rear axle stabilizer deliver even greater steering precision. The reinforced driveline ensures the best possible transmission of power to the wheels and hallmark Mercedes reliability. The 4ETS electronic traction control system optimizes grip under varying surface conditions.
AMG speed-sensitive sports steering, AMG high-performance brake system
The electromechanical AMG speed-sensitive sports steering is equipped with variable power assistance that adapts in accordance with the selected suspension mode. This system also helps to save fuel, as the power assistance only consumes energy when the driver is actually turning the steering wheel. The GL63 AMG runs as standard on machine polished, twin five-spoke 10 x 21 AMG alloy wheels sporting 295/40 R 21 tires. For the shortest possible braking distances and excellent fade resistance, there is the AMG high-performance brake system with ventilated and perforated discs at all four corners – 15.4 x 1.4 inches (front) and 13.6 x 1.0 inches (rear).
Masculine design with performance focus
Distinctive, masculine, unmistakable – these are the characteristics that define the design of the GL63 AMG. The styling fundamentals of the new GL – powerful dynamics and sporty elegance – have been further enhanced by Mercedes-AMG with specific elements that emphasize the stunning performance of this V8 top model. The hallmark, upright GL radiator grille with its central Mercedes star is augmented by high-gloss black louvers. The AMG styling includes the front valance, which features large air intakes for effective airflow to the cooling modules. On the lower air intake, shaped in true AMG fashion in the shape of a stylized "A", is a narrow gap beneath a fine black fin, through which air flows directly to the cooling modules – a perfect combination of design and technology. The chrome trim element beneath this creates visual breadth and blends perfectly with the surrounds for the LED daytime running lamps incorporated into the outer air intakes.
The AMG front valance transitions beautifully into the flared fenders. The large 21-inch AMG alloy wheels clad in wide 295 tires add almost one inch to either side of the vehicle. The side view is further enhanced by "V8 BITURBO" badges on the fenders and illuminated sills with an aluminum finish. The flared fenders at the rear connect into the AMG rear valance, which also sports a distinctive chrome trim strip, as well as a black diffuser-type panel. A visual and acoustic highlight is provided by the two chromed twin end pipes of the AMG sports exhaust system.
Exclusivity and dynamics dominate the interior
Enormous attention to detail, perfect ergonomics and a generous amount of space characterize the interior of the GL63 AMG, where the emphasis is on exclusivity and dynamics. All seven seats in the high-performance SUV are upholstered in premium leather. The electrically adjustable AMG sports seats feature double stitching in a contrasting color, as well as AMG badges in the backrests of the front seats and the outer rear seats. The dashboard, armrests and door trim are finished in MB-Tex with double stitching.
The AMG performance steering wheel features a four-spoke design and offers optimum vehicle control with perforated leather grips, a flattened bottom and aluminum shift paddles. Four instrument dials in the AMG instrument cluster provide the driver with all necessary information. Positioned in the center is a color TFT monitor, which incorporates an AMG logo and the AMG main menu.
