Depth of character: Evident on every surface.

With standard multimode, height-adjusting AIRMATIC® suspension and fully variable 4MATIC® all-wheel drive, the GLS puts its best foot forward even as seasons and surfaces challenge it. Available on the GLS 580, E-ACTIVE BODY CONTROL can camera-scan the road ahead, lean into curves, and even rock you out of a sand trap.

EQ Boost Integrated Starter-Generator

Electrifying the V8 biturbo gasoline engine is an innovative Integrated Starter-Generator. It teams with a 48-volt lithium-ion battery, plus a power supply for formerly belt-driven components like the water pump and air-conditioning compressor. These advancements help reduce weight and enhance underhood packaging. In addition to generating power and torque for immediate response, EQ Boost offers a reduction in fuel consumption.

4MATIC fully variable all-wheel drive

A newly engineered version of 4MATIC® can automatically send from zero to 100% of the engine's torque to either axle, front or rear. A transfer case with a multi-disc clutch can vary the torque distribution based on the driving conditions in the moment. While this allows for precise response to varying surfaces and individual-wheel traction off-road and in inclement weather, it can also enhance cornering in any season by favorably influencing the vehicle's handling. AMG model comes equipped with AMG Performance 4MATIC+ all-wheel drive.

ECO Start/Stop system

An ECO Start/Stop system automatically shuts off the engine at stoplights and other idle situations, to save fuel and reduce emissions. As soon as the driver lifts off the brake, the engine instantly restarts, for quick acceleration response. An added benefit of EQ Boost is that its Integrated Starter-Generator makes the restart process more seamlessly smooth than ever before. The ECO Start/Stop system can also be shut off by the driver at any time.

Active Brake Assist

Radar-based technology can alert you if you're approaching a vehicle ahead, or even some stationary objects, at a speed and distance that suggest a collision is likely. As soon as you start to brake, it can automatically provide an appropriate level of braking to help prevent a collision or reduce its severity. If you fail to respond, it can also initiate braking automatically at a range of driving speeds. The system can also detect and react to crossing pedestrians at typical city speeds.

The first system of its kind, ATTENTION ASSIST® continuously monitors up to 70 parameters of driving behavior, and can automatically alert the driver with both visual and audible warnings if it detects signs of drowsiness on long trips. With enhanced sensitivity, the system can also help detect drivers who begin their trip drowsy, and offer more useful information to drivers along their journey via a dashboard display.

Active Distance Assist DISTRONIC

A Mercedes-Benz innovation, Active Distance Assist DISTRONIC cruise control uses radar-based technology to adapt your set speed in response to the flow of traffic ahead. If traffic slows down, it can reduce your speed automatically until your path clears. If the vehicle ahead slows to a stop, it can brake to a full halt. When traffic moves, you can resume with just a tap of the accelerator or cruise control button, or it can resume automatically if the stop is under 30 seconds.
