Interior:Saddle Brown/Black MB-Tex
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.
One wildcard remains the diesel version. When the GLS-Class debuted, there was the GLS350d, which had an available 3.0-liter diesel V6 that produced 255 hp and 455 lb-ft of torque. But the new, stricter EPA testing guidelines for diesel engines put this model on hold. Recently, Mercedes-Benz announced it is scrapping plans to re-release 2017 diesel models, but it will revisit the testing process in 2018. Stay tuned for details on this.
Neither the IIHS nor the NHTSA has tested the GLS-Class for safety, but we expect nothing short of incredible ratings from Mercedes. Like the 2017 model, we expect the 2018 GLS-Class to include crosswind stabilization, trailer stability assist, automatic emergency braking, and a rearview camera all as standard features. We also expect the available options to continue to include blind-spot monitoring, lane-keep assist, an upgraded collision-mitigation system, and more.
We expect the 2018 Mercedes-Benz GLS-Class to kick off production in July 2017. Its arrival at dealers will come a few months later.
2017 Mercedes-Benz GLS450 Prices
With no changes in store, look for the 2018 GLS-Class’ pricing to come close to mimicking that of the 2017 model, which ranges from $69,925 to $125,025.
While Mercedes-Benz is generally relatively generous with incentives (for a luxury automaker), including strong lease deals, unadvertised cash incentives, and APR deals, the GLS-Class has lacked any attractive offers.
Competition for the 2018 GLS-Class will include the INFINITI QX80, the Cadillac Escalade, and the Lexus LX 570.
