Compared with its predecessor, the new generation features improved efficiency, additional DYNAMIC SELECT transmission modes, improved air suspension system (AIRMATIC) with enhanced damping system (ADS), nine-speed 9G-TRONIC automatic transmission, state-of-the-art assistance systems and the latest generation of Mercedes-Benz telematics which includes internet access and remote-start capability.
More power, more dynamism and more equipment are also offered by the new Mercedes- AMG GLS63. With a peak output of 577 hp, independent suspension and the revised AMG SPEEDSHIFT PLUS 7G-TRONIC transmission, it represents the pinnacle of the GLS model line. Standard features on the GLS63 include AMG DYNAMIC SELECT transmission modes which provide optimum flexibility and a rear-biased AMG Performance all-wheel drive system. The GLS63 also shows strength of character with its updated AMG design elements and high- quality interior.
Efficient performance: the engine line-up in the GLS
All of the engines available on the new GLS provide better performance across the model line. The powerful GLS550 4MATIC with V8 biturbo engine featuring direct injection now generates 449 hp, some 20 hp more than the preceding model, and at a maximum torque of 516 lb-ft combines outstanding performance with the high level of motoring comfort of these engines. The 3.0-liter V6 biturbo engine, also featuring direct injection, is used in the GLS450 4MATIC. This engine produces 362 hp and 369 lb-ft of torque from 1,800 rpm, and like all GLS models has an ECO start/stop function.
As the effortlessly superior top-of-the-range model in the series, the Mercedes-AMG GLS63 now has 577 horsepower, over 27 horsepower more than its predecessor. The peak torque of 561 lb-ft is now available from just 1,750 rpm.
Alongside the gas engine offerings, in the GLS350d 4MATIC offers a proven V6 diesel engine rated at 255 hp and with ample torque of 455 lb-ft.
At the launch of the new GLS generation, all versions will feature the nine-speed 9G-TRONIC automatic transmission as standard (except the Mercedes-AMG GLS63), optionally in combination with low-range gearbox and center differential lock.
Comprehensive stability: DYNAMIC SELECT, AIRMATIC with enhanced ADS and ACTIVE CURVE SYSTEM
With DYNAMIC SELECT, the new GLS provides up to six transmission modes. In addition to the settings COMFORT, SLIPPERY and SPORT, with the DYNAMIC SELECT Controller in the center console, the driver can additionally choose INDIVIDUAL or an OFF-ROAD mode. If the GLS model is equipped with the optional Off-Road Engineering package, OFF-ROAD+ mode is also available. With this, the low-range gearbox and center differential lock intervene if necessary in order to ensure a high degree of drivability in demanding off-road terrain. This is further boosted by the extended functions of the AIRMATIC air suspension with raised ride heights for a ground clearance of up to 12.5 inches (306 mm) and a fording depth of up to 23.6 inches (600 mm).
On the GLS63, the DYNAMIC SELECT system receives the AMG treatment with the inclusion of a SPORT+ mode in place of the OFF-ROAD mode available on other models.
In addition to several ground-breaking powertrain configurations, the retuned AIRMATIC air suspension with enhanced ADS damping characteristics guarantees extremely stable driving, altering dampening depending on the current DYNAMIC SELECT mode. SPORT focuses on the greatest possible lateral dynamics with the best possible ride quality. Conversely, COMFORT mode enables maximum ride quality with the best possible dynamics.
The optional active roll stabilization ACTIVE CURVE SYSTEM uses active anti-roll bars on the front and rear axle and reduces the roll angle of the body during cornering. Better driving comfort when cornering and driving off-road are also part of the advantages of the ACTIVE CURVE SYSTEM.
