The high aspirations of the new Mercedes-Benz GLS are likewise clearly apparent in its engine line-up. Powerful six and eight-cylinder engines deliver the motoring comfort and effortlessly superior power that suit the characteristics of this luxurious car.

Shortly after the model series launch, the introduction of the GLS 580 4MATIC (combined fuel consumption: 10.0-9.8 l/100 km; combined CO₂ emissions: 229-224 g/km)^[1] will mark the world premiere of a new, electrified V8 petrol engine with 48-volt on-board electrical system and integrated starter-generator. It has an output of 360 kW (489 hp) and 700 Nm of torque, with a further 250 Nm of torque and 16 kW/22 hp available via EQ Boost over short periods. The integrated starter-generator (ISG) is responsible for hybrid functions such as EQ Boost or energy recuperation, while allowing fuel savings that were previously reserved for high-voltage hybrid technology.

ISG eliminates the need for a belt drive for ancillary components at the front of the engine, which reduces its overall length. The slim design of the in-line engine, together with the physical separation of intake/exhaust, creates space for close-coupled exhaust aftertreatment. The 48 V on-board electrical system serves not only high power consumers, such as the water pump and air-conditioning compressor, but also the integrated starter-generator (ISG), which also supplies energy to the battery by means of highly efficient energy recuperation.

The Mercedes-Benz GLS 450 4MATIC, a six-cylinder in-line engine electrified with 48-volt technology, is only available outside of the EU. Its performance data: 270 kW (367 hp) and 500 Nm of torque, with a further 250 Nm of torque and 16 kW/22 hp available via EQ Boost over short periods.
