The 2017 Porsche Cayenne Hybrid ranks 1 out of 22 Luxury Midsize SUVs. The 2017 Porsche Cayenne E-Hybrid emulates everything you expect from Porsche: affluence, elegance, and performance. It's both sporty and posh, but there's isn't much room for your belongings in the back, and its fuel economy is lower than what you might expect from a plug-in hybrid.
Pros Stylish and comfortable interior Agile handling Quick acceleration Feature-rich infotainment system
Cons Small cargo space Poor fuel economy for a hybrid
The 2017 Cayenne gets Porsche's latest (PCM 4.0) touchscreen infotainment system on every trim level, improving functionality. Limited Edition Cayenne and Cayenne S E-Hybrid Platinum models also join the range, bringing the trim level count up to eight. The Cayenne Diesel has been discontinued due to the Volkswagen diesel emissions scandal.
Pros Truly impressive handling for a crossover SUV Wide selection of strong engines available Exquisite interior and build quality Plenty of customization options
Cons Relatively small cargo capacity for the segment Quite a few optional features should be standard given the price tag
The Cayenne is a spicy-hot mix of luxury, off-road ability, and sports-car performance—just what you’d expect in a Porsche SUV. The base model has a 300-hp V-6; the S makes 420 hp and the GTS makes 440 hp, both from a twin-turbo 3.6-liter V-6. There's also the S E-Hybrid. All have an eight-speed automatic and all-wheel drive. A leather-lined cabin and infotainment with navigation make it a comfortable road tripper. The Cayenne is easy to hustle around curves and equally ready for family duty. The EPA rates the Cayenne S E-Hybrid at 46 MPGe in combined driving while depleting the battery charge and using the electric motor. As a more conventional hybrid, the Porsche is rated at 22 mpg combined. That won’t rattle the worldview of many Tesla owners, but it’s substantially better than other Cayenne models.
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
