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
Pro: Well-built and spacious cabin Comfortable seats in the front and second rows Strong acceleration, especially in the XC90 T8 Cons: Third-row seats are only good for small adults or kids One USB port in a luxury family crossover is unacceptable
Pros Sharp new look and style; spacious second- and third-row seating; many standard safety technology features; confident handling; available hybrid model.
Cons Overly busy and firm ride quality; base engine comes up short on performance and real-world fuel economy; some touchscreen controls are hard to use.
Endnote: The XC90's suspension tuning is another mixed bag. On smooth pavement, the XC90 feels calm and controlled on its available air suspension. But over ruts, bumps and broken pavement, the vehicle delivers too many impacts and jitters to the occupants for a luxury SUV. We've only driven the XC90 with the big 21-inch wheels, but based on that experience, we recommend going with smaller wheels if possible to help smooth out the ride. Around turns, there's better news, as the XC90 inspires confidence with its planted character, feeling smaller and lighter than it really is.
The 2016 XC90 is raising the design bar in the premium three-row large crossover segment. And with a long roster of standard equipment that includes leather seating, navigation, a panoramic sunroof, a smartphone-like infotainment system and state-of-the-art safety gear, the XC90 provides an intriguing alternative to the German-branded competition.
