Engine and Drivetrain

The GLS 450 4MATIC is powered by the M256M 3.0-litre turbocharged inline-six petrol engine displacing 2,999 cc, paired with a 48-volt belt-driven integrated starter-generator. Rated output for the 2027 model year is 375 hp (280 kW) at 5,800-6,100 rpm and 560 Nm (413 lb-ft) of torque, with the integrated starter-generator contributing a further 23 hp and 205 Nm of transient EQ Boost under acceleration.

Mercedes-Benz quotes 5.4 seconds for 0-60 mph and an electronically limited top speed of 209 km/h (130 mph).
