Both the 2018 and 2019 GLS model years come in three trim levels: the GLS 450, 550, and powerful AMG GLS 63. The newer GLS has the same charming exterior as the previous year's. LED headlamps sit proudly around the iconic GLS grille emblazoned with the Mercedes-Benz tri-star. One of the changes for the new GLS is the Night Package, which adds handsome black accents to your GLS' outward appearance.

The 2018 and 2019 GLS have a three-engine lineup that lets you choose your perfect level of power. It starts with the 450's standard 362-horsepower twin-turbo V-6 that produces 369 pound-feet of torque. The 550 is equipped with a twin-turbo V-8 that packs 449 horsepower and 516 pound-feet of torque. Finally, at the front of the pack is the AMG 63 with its 577-horsepower V-8 that creates 561 pound-feet of torque.

Each GLS comes with the 4MATIC all-wheel-drive system that gives you an enhanced grip on the road - a valuable feature for those living in places that experience harsh weather. Use the steering-wheel-mounted paddle shifters to give your automatic transmission a manual feel. Further control your engine with the Dynamic Select drive mode options, which range from fuel-friendly to sport mode.

Each GLS offers a capable drive, but if you want to top performance, opt for an AMG trim. It's the best of the best, with AMG-specific upgrades that increase your GLS' dynamic capabilities. Also offered are an adaptive damping system, AMG sport suspension, and Mercedes' active curve system, along with many other features.

The GLS seats seven people in three rows that don't cut corners when it comes to comfort. The easy-entry second row makes the third row more accessible for the back seat riders. If you need to stow your gear in your GLS, the power-folding third row and split-folding second row allow up to 93.8 cubic feet of space for everything you may need during your travels. The GLS' cabin is inlaid with real wood and leather-upholstered throughout to create a first-class feel you won't find anywhere else.

If you want to please your antsy back-seat riders, equip your GLS with the dual-screen entertainment center on the backs of the front seat headrests. For the front seat, the available 8-inch touch screen on the dashboard lets you perform a huge number of useful and entertaining tasks. The GLS' tech not only assists but excites as well.

The 2018 and 2019 GLS' access to Mercedes-Benz' safety technologies makes them some of the safest SUVs on the road. Features such as blind-spot assist, active parking assist, brake assist, adaptive braking, and the drowsy-driver-sensing Attention Assist are just a handful of the numerous features that make safety more proactive rather than simply reactive.
