The GLS-Class made its debut as a new model in 2017, but it was essentially a restyled version of the discontinued GL-Class. With it still quite fresh, we expect the 2018 GLS-Class to carry on without any changes.
As a carryover model, we expect no noticeable changes to its styling, as it’ll continue with its refreshed-GL-Class appearance. The same goes for the interior, which in 2017 gained a touchpad for the infotainment system, a large display screen, Apple CarPlay, and more.
With its looks remaining the same, we anticipate no changes in the GLS-Class’ standard features. These will include 19-inch wheels, a self-leveling suspension, auto-dimming side-view mirrors, automatic headlights, LED daytime running lights and taillights, a sunroof, leatherette upholstery, heated front seats, dual-zone climate control, and a power liftgate.
Buyers looking to add more features will be able to opt for the Premium Package, which will add keyless entry and ignition, power passenger seat with memory, lighted door sills, ambient lighting, and navigation. There will also the Lighting Package, which will add adaptive LED headlights and auto high beams.
The GLS-Class will continue to include three models: GLS450, GLS550, and AMG GLS63.
The base GLS450 will include a 3.0-liter turbocharged V6 engine that will crank out 362 horsepower and 369 pound-feet of torque. The GLS550 will add a 4.6-liter turbocharged V8 with 449 hp and 516 lb-ft of torque. Finally, the range-topping AMG GLS 63 will add a 5.5-liter V8 with 577 hp and 561 lb-ft of twist. The two non-AMG models will continue with a nine-speed automatic transmission, while the AMG GLS 63 will keep its existing seven-speed automatic transmission.
