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
If you've got a lot to haul, the GMC Yukon range is one of the best ways to do it. But if not, consider a crossover that will use much less fuel and be better to drive. Its spec sheet may read like an SUV from a different era, but the 2017 GMC Yukon range is a highly-refined passenger, cargo, and trailer-hauler that makes a compelling choice to those who need to carry around more than just the family.
Pros Refined demeanor Sauve interior Denali's Magnetic Ride Control Automatic emergency braking
Cons Expensive, especially with options Third row folds flat but takes up a lot of room A crossover may make more sense for many
For 2017, the GMC Yukon receives low-speed automatic braking paired with the existing forward collision warning system and a teen-driver management system. Cooled seats have now been replaced with ventilated seats, the rear entertainment system input has been updated, and a head-up display is standard on the Denali trim.
Pros Seating for up to nine passengers Standard V8 engine delivers ample passing power and a stout tow rating Clean cabin design is one of the best in the class Available two-speed transfer case gives the Yukon the ability to tackle difficult off-road terrain.
Cons High cargo floor height makes loading bulky items difficult Hard to maneuver in tight spaces Less cargo room than car-based SUVs of similar size Maximum passenger capacity is available only in the base model Engine doesn't respond to gas pedal inputs quickly enough.
The 2017 GMC Yukon ranks 3 out of 6 Large SUVs. The GMC Yukon gets high scores and a high ranking in the small – but fierce – large SUV class. Its strong performance and attractive interior keep it ranked above most other options.
Pros Decent power Stellar fuel economy for the class Premium interior materials Large cargo hold in XL trim
Cons Slow-to-shift six-speed transmission Limited cargo space in non-XL models
