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
The 2017 Cadillac XT5 ranks 16 out of 21 Luxury Midsize SUVs. The new-for-2017 Cadillac XT5 has a well-built cabin and spacious rear seats. It also has a long list of features, including several driver assistance options. However, many class rivals have more impressive engines, and the XT5's handling ability draws mixed reviews.
Pros First-rate cabin materials Spacious rear seats Excellent safety ratings
Cons Uninspiring engine
The new 2017 Cadillac XT5 combines a large interior with a pleasing ride, plentiful outward visibility and a striking design. If you're shopping in the competitive compact luxury SUV segment, the XT5 is worth a look.
Pros Pleasing ride and handling Generous interior space Excellent forward visibility.
Cons Only one engine choice Tech interface can frustrate All-wheel drive not available in base trim.
The 2017 Cadillac XT5 is an evolutionary improvement over the SRX in most ways, but it’s part of a larger leap for Cadillac. The 2017 Cadillac XT5 is the successor to the GM luxury brand's smallest SUV, the SRX. New this model year, it's a design that lays some heavy bets on lighter-weight construction, a library-themed interior, and other upscale cues that Cadillac hopes will lure away buyers from the likes of the Audi Q5 and Benz GLC.
Pros Fine details everywhere inside Suite of fuel-efficiency and safety tech Easy drivability, perky powertrain Softer, less chiseled look than SRX
Cons Rear seat still a bit tight across Lacks the sport-sedan pedigree of some rivals No hybrid in the lineup CarPlay outshines Cadillac's own CUE
