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
A nip and tuck for this year isn't enough to ignore the wrinkles in the aging 2018 Infiniti QX80.
Pros Far more attractive than before V-8 is charming Beautiful interior upholstery Active safety features aren't expensive
Cons Traces roots back to 2010 and it shows No Apple CarPlay or Android Auto Still big and cumbersome despite tech Very poor fuel economy
As big as a luxury yacht and almost as opulent inside, the QX80 is Infiniti’s answer to the Cadillac Escalade. It’s built on a full-size truck frame and powered by a 400-hp 5.6-liter V-8 with a seven-speed automatic; rear-wheel drive is standard and all-wheel drive is optional.
Pros Handsome visage, burly naturally aspirated V-8.
Cons Clumsy handling, heavy drinker, outdated and missing technology.
The 2018 QX80 receives a noticeable exterior makeover. New LED headlights, taillights and foglights complement redesigned front and rear bumpers and a rear tailgate. The QX80 also rides along restyled wheels wrapped in softer sidewall tires, which, along with a retuned suspension, are intended to improve ride comfort.
PROS Powerful V8 delivers strong acceleration and a high tow rating Capable and controlled handling for a big SUV Brakes deliver strong stopping power Easy to see out of
CONS Ride quality degrades with optional 22-inch wheels Third-row seat is difficult to access and a tight fit for adults Updated interior hasn't changed enough Engine is thirstier than most
