2020 Mercedes GLS 580 - OFFROAD TEST!

Powertrain: all engines have an EQ Boost integrated starter generator

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

The introduction of the GLS 580 4MATIC will mark the world premiere of a new, electrified V8 gasoline engine with 48-volt on-board electrical system and integrated starter generator. It has an output of 483 hp and 516 lb-ft of torque, with a further 184 lb-ft of torque and 21 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 after treatment. 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 is also available with a six-cylinder in- line engine electrified with 48-volt technology. This sophisticated engine produces 362 hp and 369 lb-ft of torque, with a further 184 lb-ft of torque and 21 hp available via EQ Boost over short periods.

4MATIC variable all-wheel drive: agile on the road, superior when off- road

In all variants of the new GLS, power is transmitted by the 9G-TRONIC automatic transmission. The broad ratio spread of gears from one to nine allows a clearly perceptible reduction in engine speed and is a decisive factor behind the high level of energy efficiency and ride comfort. A transfer case with an electronically controlled multi-plate clutch is also fitted as standard. This allows a variable transfer of drive torque from 0-100 percent (torque on demand) between the axles.

Also new, and available as an option on the GLS 580, is a transfer case specially configured for superior off-road driving characteristics. In addition to the controlled multi-plate clutch with torque-on-demand function, it also features a reduction gear for off-road driving.

When driving on the road, and particularly when cornering, the two fully networked transfer cases with torque-on-demand function allow a further improvement in handling safety and agility by specifically influencing the degree of yaw to induce oversteer or understeer.

Driver assistance systems: even better support

The new GLS is equipped with the latest generation of Mercedes-Benz driver assistance systems giving cooperative support to the driver. These systems further enhance the level of active safety.

When Active Distance Assist DISTRONIC with route-based speed adaptation is activated, the new GLS is able to recognize and respond to traffic jams or slow-moving traffic with the help of information from LiveTraffic before the driver becomes aware of the hazard. For example, when a traffic jam is detected on the highway (and if the driver does not choose a different response), DISTRONIC reduces the speed to around 62 mph (100 km/h) as a precaution.

A new feature of the Driver Assistance package: when actually driving in a traffic, Active Stop-and-Go Assist is substantially able to perform the tasks of keeping the vehicle in the lane and maintaining a safe distance with a high level of availability at speeds up to around 37 mph (60 km/h). In addition, restarting can be automatic up to one minute after coming to a stop. Once the traffic jam clears, the GLS accelerates back up to the speed preset for Active Distance Assist DISTRONIC with route-based speed adaptation. If traffic signs differ from this, the sign posted speed limit is automatically given priority.

Suspension: AIRMATIC air suspension as standard

The GLS comes with the enhanced AIRMATIC air suspension system with Adaptive Damping System Plus fitted as standard. This setup uses highly complex sensor systems and algorithms to adapt the damping characteristics to the road condition and driving situation in real time. All components have been enhanced compared with the previous generation, and the wheel suspension mountings have been optimized to maximize ride comfort. In addition, the air suspension keeps the car at the same level, regardless of the load on board.
