The GLS-Class officially makes its debut for 2017, though it's really a slightly revised version of the outgoing GL-Class. Highlights include modified exterior styling, a newly standard nine-speed automatic transmission (except on the AMG GLS 63) and a touchpad-operated infotainment system with a larger screen and available Apple CarPlay. Also, all engines except the GLS450's turbocharged V6 get a bit more horsepower this year.
Pros Third row is large enough for adults Spirited acceleration with any of the three gasoline engines Impressive fuel economy with the diesel engine Quiet cabin with high-end trimmings and features.
Cons Diesel-powered model feels relatively slow when passing and merging Big price jump from the six-cylinder models to the V8-powered versions.
The 2017 Mercedes-Benz GLS gets the first-class upgrade along with its name change—and a Maybach edition is waiting in the wings. The 2017 Mercedes-Benz GLS-Class marks a significant, mid-cycle upgrade for what was previously knew as the GL-Class. As part of a nomenclature change sweeping the entire brand, each of the German luxury maker's sport-utility vehicles has received new badging and a full or partial makeover to bring the lineup into more obvious parallels with its sedans—so this large, three-row SUV becomes the GLS, to align it with the largest S-Class sedan. Hence the S in its new name.
Pros Spacious, flexible interior Rugged-lux, with some added panache Great set of safety, infotainment features
Cons Not an entirely new vehicle Some switchgear looks dated Cumbersome COMAND interface
The 2017 Mercedes-Benz GLS-Class ranks 1 out of 8 Luxury Large SUVs. The 2017 Mercedes-Benz GLS hits most of the right notes for a large SUV. It boasts a supple ride, three powerful engine choices, three rows of roomy seats, and the same level of luxury that has come to be synonymous with the brand. However, the GLS has fewer standard features than many rivals do, and its available V8 engines are less fuel-efficient than those offered by many competitors.
Pros Powerful engine lineup Smooth ride Three rows of spacious seats
Cons Fewer features than some rivals V8 engines get subpar fuel economy
For 2017, the GMC Yukon XL now adds automatic low-speed emergency braking to the existing forward collision warning system and a teen-driver management system. Cooled seats have now been replaced with ventilated seats, the input capability for the rear entertainment system has been updated, and a head-up instrument display is standard with the Denali trim.
Pros Seating for up to nine passengers Nicer interior than other truck-based, full-size SUVs All-terrain mobility with four-wheel drive Tow rating is higher than average for the class.
Cons The Yukon XL's size and weight make it less maneuverable around town Lazy throttle response makes it feel weaker than it is Only the base model delivers nine-passenger capacity Utility of cargo space is compromised by a high load floor.
In the world of full-size family SUVs, the 2017 GMC Yukon stands head and shoulders above the rest. The Yukon, with its longer sibling, the Yukon XL, is more modern in design than the aging Ford Expedition and Toyota Sequoia, yet its abilities are in full view, reminding all competitors that this slick big rig is still a workhorse at heart. While SLE and SLT trim get by with a 355-horsepower 5.3-liter V8, the Denali trims are equipped with a 420-horsepower 6.2-liter unit that knows no equal in this class. And while it’s true the Ford Expedition and Lincoln Navigator can tow more weight, neither can match the Yukon’s cutting-edge styling, driver assists or optional technology features.
Pros If you need the big hauling, towing and cargo abilities of a full-size SUV, GMC’s Yukon, Yukon XL and Denali SUVs for 2017 have all the bases covered. You’ll get style, supreme luxury and cutting-edge features, plus with the XL, added space that a Nissan Armada or Toyota Sequoia can’t match.
Cons The 2017 GMC Yukon XL is a big SUV that at times can feel like a bull in a china shop. If you just need room for seven or eight passengers, a more maneuverable midsize-crossover SUV like the GMC Acadia Limited, Honda Pilot or Ford Explorer might be a better choice.
