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 Jeep Grand Cherokee Trackhawk is the third Fiat Chrysler vehicle to have the unhinged supercharged V-8 stuffed under its hood, and it’s the quiet Hellcat next door. Not literally, of course—have you heard a blown Hemi V-8 at full whack?—but with standard all-wheel drive mitigating the engine’s tire-spinning proclivities, plus its under-the-radar looks, the Trackhawk can at least pass for an upstanding citizen. With more traction than any Hellcat yet, the Trackhawk has quite a lot of poke despite its pork—the engine adds 259 pounds over the already heavy 475-hp Grand Cherokee SRT. Nonetheless, Jeep claims it can reach 60 mph in 3.5 seconds. That time is on par with the nearly 1000-pounds-lighter, automatic-equipped Dodge Hellcats we’ve tested. (The quickest was the Charger, which reached 60 mph in 3.4 seconds.) Per Jeep, the quarter-mile is expected to fly by in 11.6 seconds (at 116 mph!), and, with no electronic governor, the Trackhawk is said to surrender to atmospheric resistance at 180 mph.
