The 2017 BMW X5 remains one of the top picks in the very competitive midsize luxury SUV class. Strong performance, a luxurious cabin and an efficient diesel engine option help distinguish it from its accomplished rivals.
Pros Strong performance from every model Luxurious and comfortable cabin that lives up to its price tag Optional diesel engine is as potent as it is efficient A long list of optional features allows for a wide range of customization.
Cons Less legroom in the second row compared to some of its competitors Optional third-row seats are tight even for children.
The 2017 BMW X5 boasts a solid set of powertrains and features that move the sedan toward the top of any list of luxury SUVs. BMW's charge into every SUV segment hasn't watered down the one that started it all. The 2017 BMW X5 is a benchmark for luxury SUVs and the bar by which many are compared. Its off-road ability is eclipsed only by its on-road manners, and its interior style and comfort make this SUV a must-see for shoppers.
Pros Bright and stunning interior cabin Very advanced safety features available Strong powertrains, top to bottom Comfortable and quick
Cons Exterior is languishing, a bit Very small third row Price can balloon up to six figures (!) now Hybrid isn't very fuel efficient either.
Visually, this hybrid X5 is differentiated only by minor details, such as the door on the front fender that houses the charge port and the model-specific badging inside and out. In this way, this X5 mostly hides the fact that it's electrified; you can even opt for 19- or 20-inch wheels or an M Sport package, further obscuring the fact that it’s designed to save energy, not waste it M-style. One of the hybrid’s disadvantages is its smaller cargo hold, which shrinks significantly in order to make room for the lithium-ion batteries. And in a prototype that we drove last year, the switch between electric and gasoline-fueled travel was discernible, although we expect that issue to be ironed out by the time of launch. Taking into consideration the considerable extra heft and the expected higher cost, drivers of all stripes—eco-minded, performance-minded, and everyone in between—might conclude that they’re better off with a nonhybrid gasoline or diesel X5. But as we know, it’s government regulations that are providing the impetus behind automakers’ rush to plug-ins, not consumer demand—at least not yet.
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
