2027 MERCEDES-BENZ GLS 450 4MATIC (X167) — US SPECIFICATION

Engine and Drivetrain

The GLS 450 4MATIC is powered by the Mercedes-Benz M256 3.0-litre turbocharged inline-six petrol engine displacing 2,999 cc, paired with a 48-volt EQ Boost integrated starter-generator. The engine produces 375 hp (280 kW) at 5,800-6,100 rpm and 560 Nm (413 lb-ft) of torque from 1,800 to 5,800 rpm; the integrated starter-generator contributes a further 20 hp and 184 Nm momentarily under load and supports engine-off coasting and restart. The engine uses direct petrol injection, a twin-scroll turbocharger and a 48V electric auxiliary compressor that fills in low-rpm response, and runs a 10.5:1 compression ratio. Drive reaches the road through the 9G-TRONIC nine-speed torque-converter automatic and 4MATIC permanent all-wheel drive. Mercedes-Benz quotes 0-60 mph in 5.8 seconds and an electronically limited top speed of 209 km/h (130 mph). Braked towing capacity is 3,493 kg (7,700 lb).

Chassis, Steering and Brakes

Suspension is independent at both ends — double-wishbone front, multi-link rear — carried on AIRMATIC air springs with adaptive damping and automatic self-levelling, allowing ride height to be varied with speed and drive mode. Steering is an electromechanical rack-and-pinion system with speed-sensitive assistance. Braking is by ventilated discs at all four corners with ABS, electronic brake-force distribution and Brake Assist. This unit rides on 21-inch alloy wheels with a staggered tyre fitment of 275/45 R21 at the front and 315/40 R21 at the rear.
