The 2020 Mercedes-Benz GLS-Class overperforms in any configuration. We’re just wonderful with the foundation 2020 GLS 450, which quickly earns a 7 out of 10 score for its at ease ride and its powerful, smooth powertrain.

Underhood, the GLS 450 helps make use of a 362-horsepower, 369 pound-ft of torque 3.-liter turbo-six paired with a 48-volt electric powered starter generator and battery that can provide an extra 21 hp and 184 lb-ft of torque. The 48-volt procedure requires away any trace of turbo lag and helps the powertrain compensate for electrical attract from equipment this kind of as the air conditioning procedure.

The common motor is so powerful, so silent, and so refined that it’s challenging to visualize opting for the GLS 580 with its 483-hp, 516 lb-ft of torque four.-liter turbocharged V-8. The GLS 580 also added benefits from the 48-volt integrated starter generator system’s electricity increase and it uses a version of the 9-pace automatic transmission uncovered in the GLS 450.

Small of supplying extra electricity to manage trailers as weighty as 7,650 kilos, the large motor is overkill for most people. In our first preview push, we uncovered transmission tuning in the GLS 580 to downshift as well eagerly, vaulting the huge SUV to illegal speeds in a blink.

2020 Mercedes-Benz GLS-Class ride and handling

Underneath, the GLS will come common with an air suspension that can be softened or firmed up at the faucet of a push method button. The softest method floats over bumps with land yacht-like consolation, although Activity and Activity+ modes tighten reflexes for extra control. We uncovered Activity to be the Golidlocks of suspension modes, and Mercedes conveniently includes an Specific placing that allowed us to preserve the Activity suspension placing with the Comfort drivetrain setup.

Optional on both of those engines is the E-Active Entire body Regulate procedure that uses the 48-volt integrated starter motor to control every single wheel’s spring forces independently. Using the adaptive cruise control’s myriad sensors that check out the street forward, E-Active Entire body Regulate prepares every single wheel for pavement imperfections. The procedure performs fabulously to tame bumpy roadways, but we uncovered it to final result in unnatural-sensation motions on winding pavement as it attempted to preserve the SUV’s passenger compartment degree. Consider both of those, but we’re not guaranteed we’d shell out for E-Active Entire body Regulate offered how well the GLS rides on its stock air suspension.

The GLS has a nimble come to feel in urban circumstances and it settles easily into superior-pace highway cruising. Its steering provides little communication to the driver, but that’s not really the place of a hulking SUV.

An optional off-street offer includes a particular four-wheeling traction control method, although it’s challenging to visualize many potential buyers will choose the GLS for its adventuring skills.
