Mercedes-Benz GLS 450

2027 MERCEDES-BENZ GLS 450 4MATIC — US SPECIFICATION

Generation and Data Status

This unit is the all-new next-generation GLS, not the outgoing model. It is identified as such by the Mercedes-Benz Star pattern signature inside the headlamps, the redesigned grille with its chrome surround and the bonnet-standing star — the exact exterior changes Mercedes-Benz describes for the new car. Mercedes-Benz has not yet published full specifications for this generation and notes that figures released so far may be preliminary estimates. Accordingly this sheet carries only what can be verified for this specific vehicle: powertrain and body data decoded from its VIN through the NHTSA vPIC database, and equipment visible in the seller's own listing and photographs. Dimensions, kerb weight, load volumes, torque, towing capacity and performance times are deliberately omitted rather than carried over from the previous-generation car, and will be added once Mercedes-Benz homologates and publishes them.

Engine and Drivetrain

The GLS 450 4MATIC is powered by the M256M 3.0-litre turbocharged DOHC inline-six petrol engine displacing 2,999 cc, with direct injection and a 48-volt mild-hybrid integrated starter-generator. Rated output is 375 hp (280 kW). Mercedes-Benz states that the new-generation six-cylinder raises torque over the previous car but has not published the figure, so no torque value is quoted here. Drive is through a nine-speed automatic transmission to the 4MATIC all-wheel-drive system. The starter-generator provides brief electrical torque assistance, restarts the engine for the stop-start and coasting functions and supplies the 48-volt subsystem; the vehicle cannot be driven on electric power alone and is a petrol vehicle for registration and tariff purposes.

Exterior

This unit carries the AMG Line exterior package, identified in the photographs by the diamond-block grille, AMG-specific bumpers and AMG multi-spoke alloy wheels with the AMG name cast into the spokes. Gloss-black trim is fitted to the window surrounds, mirror caps and roof rails. Lighting is the new-generation DIGITAL LIGHT system with the partial high-beam function, with the Mercedes-Benz Star pattern rendered inside both the headlamps and the tail lamps. A bonnet-standing Mercedes-Benz star is fitted. The vehicle also has a panoramic sliding sunroof, privacy glass, running boards and a power tailgate.

Interior and Seating

Seven seats are arranged across three power-adjustable rows. Upholstery is black leather-appointed over heated and ventilated power front seats with memory. The cabin carries ambient lighting, multi-zone automatic climate control with dedicated second and third-row outlets, illuminated door sills and star-motif floor mats.

Infotainment and Connectivity

The MBUX system drives a central touchscreen alongside a digital instrument cluster, with a centre-console touchpad controller and steering-wheel touch controls. Wireless Apple CarPlay and Android Auto are supported, along with natural-language voice control and wireless smartphone charging. Audio is by the Burmester surround sound system. The MBUX High-End Rear Entertainment system provides two 11.6-inch HD displays with integrated cameras for second-row passengers.

Driver Assistance and Safety

Driver assistance includes Active Brake Assist, Active Distance Assist DISTRONIC adaptive cruise control, Active Lane Keeping Assist, Active Blind Spot Assist, Rear Cross-Traffic Alert, Evasive Steering Assist and Traffic Sign Assist, with a 360-degree camera system and the Parking Package. Passive protection comprises front, side and knee airbags with side-impact protection across all three rows, three-point belts with pretensioners and load limiters throughout, and ISOFIX anchorages. The VIN decode places the vehicle in FMVSS gross vehicle weight rating Class 2F, 7,001 to 8,000 lb (3,175 to 3,629 kg).
