motive design, exclusive appointments, plenty of space for up to seven people and further improved driving dynamics make the GLS 63 an unrivalled package in the luxury SUV segment. Superior driving pleasure is guaranteed by the powerful 4.0-litre V8 biturbo engine with 450 kW (612 hp) and an integrated EQ Boost starter-alternator.
The 16 kW (22 hp) ancillary unit supplies the 48-volt electrical system, and its boost function provides assistance at low engine speeds. Mercedes-AMG GLS 63 4MATIC+ also meets higher dynamic expectations thanks to its fully variable AMG Performance 4MATIC+ all-wheel drive, the AMG SPEEDSHIFT TCT 9-speed automatic transmission and the AMG ACTIVE RIDE CONTROL air suspension with active roll stabilisation based on the AMG RIDE CONTROL+ air suspension system. The unmistakable design idiom of the new Mercedes-AMG GLS 63 4MATIC+ indicates the sheer power of the Performance model. The AMG-specific radiator grille with vertical louvres in high-gloss chrome is larger than in other AMG models. It characterises the front view in conjunction with the expressive bonnet, the heavily contoured powerdomes and the MULTIBEAM LED headlamps included as standard. The look is reinforced by the newly designed AMG front apron with an integrated jetwing in high-gloss black, the front splitter, the jetwing trim strip in silver chrome and the striking, sporty side air inlets. The flared wheel arches, side skirts and exterior mirror housings are painted in the vehicle colour, while the window surrounds are in high-gloss chrome. The newly designed, width-emphasising AMG rear apron with a sporty diffuser dominates the rear view in conjunction with the AMG exhaust system with two rectangular, characteristically corrugated twin tailpipes. The Mercedes-AMG GLS 63 4MATIC+ is shod as standard with 21-inch 10-spoke light-alloy wheels painted in tantalite grey with a high-sheen finish. For further individualisation, six further wheel variants with diameters of up to 23 inches are available. The GLS is given an even more expressive and distinctive character by the optional AMG Night package. Striking exterior features in high-gloss black, e.g. the jetwing trim strip and front splitter, the exterior mirror housings and the trim strip in the AMG rear apron, exude sporty elegance. Anodised window surrounds and thermal insulation glass from the B-pillar to the rear, the black-chrome twin exhaust tailpipes and the optionally available AMG light-alloy wheels painted in matt black round off the expressive look. The interior of the GLS 63 is spacious, displays outstanding quality and has plenty of space for up to seven people. An authentic AMG atmosphere is ensured by the AMG sports pedals in brushed stainless steel with rubber studs, illuminated door sill panels with "AMG" lettering, black floor mats with "AMG" lettering and ambient lighting. High-quality materials for the dashboard and door beltlines in ARTICO man-made leather, plus high-gloss anthracite limewood trim elements, accentuate the high-end ambience. For the first time the AMG 4.0-litre V8 biturbo engine of the Mercedes-AMG GLS 63 4MATIC+ is equipped with an integrated EQ Boost starter-alternator. It combines a starter motor and an alternator in a single, powerful electric motor compactly integrated between the engine and the transmission. The briefly and additionally available 16 kW (22 hp) of output and 250 Nm of torque allow particularly fast sprints from a standstill and intermediate sprints, e.g. when overtaking. Moreover, this innovative component not only supplies the 48-volt electrical system, and is not only used as a power generator, but also performs hybrid functions. These include boost, recuperate, load point shift, gliding and the virtually imperceptible restarting of the engine with the start/stop function. For the first time, the EQ Boost starter-alternator is also responsible for idle speed control. This allows fuel savings that were previously reserved for high-voltage hybrid technology. Furthermore, the sophisticated 48-volt electrical system allows the use of new technologies – it reliably supplies the on-board electrical consumers (e.g. active stabiliser bars or heating elements) with energy, while still ensuring full driving power. Other characteristic features of the AMG 4.0-litre V8 biturbo engine: the two turbochargers are positioned not on the outside of the cylinder banks, but inside the cylinder "V". The main advantages of this design are the compact engine construction, optimal response and low exhaust gas emissions. In the GLS 63 it develops an output of 450 kW (612 hp). The performance of the V8 biturbo engine is enhanced by a further 16 kW courtesy of the integrated starter-alternator – resulting in impressive torque of up to 850 Nm. Acceleration from 0 to 100 km/h takes 4.2 seconds, while the top speed is 250 km/h (electronically limited). 280 km/h is possible with the optional AMG Driver’s package.
