GLS [First drives] Mercedes-Benz GLS (X166)


The Mercedes-Benz GLS, formerly Mercedes-Benz GL-Class, is a full-size luxury crossover SUV produced by Mercedes-Benz since 2006. The GLS is considered the flagship of the marque's SUV lineup, although the body-on-frame G-Class (originally intended for military off-roading but also offered in luxurious trims) is more expensive and has been in production longer.

2017 Mercedes-Benz GLS test drive
First Drive: 2017 Mercedes-Benz GLS
— Hochgurgl, Austria

Even before landing in Innsbruck, Austria on my way to drive the 2017 Mercedes-Benz GLS, I’ll admit I already had some expectations about the vehicle, both positive and negative. Firstly, there were reservations about the ride and handling. Past experience tells me that driving such a massive SUV can feel a bit like riding a bull. Especially if the driver feedback is dialed back (often in the name of NVH reduction), the pitch and roll from sheer weight can make the car feel like it’s got a life of its own. On this trip the alpine roads would be our potential china shop, with the petite Euro hatchbacks playing the part of the china.

Driving such a massive SUV can feel a bit like riding a bull.

On the other hand, I expected a high-end experience in terms of comfort and quality from a brand new vehicle from the pedigreed German automaker. It’s Mercedes. I want the car to impress my passengers with its opulence. The “S” in the “GLS” signifies its status as a top-of-the-line luxury vehicle alongside the indulgent S Class. Immediately, these expectations were met. The materials and touchpoints inside the GLS are all attractive to both eye and hand. The AMG Line interiors in the available testers offered a balanced sense of tailored craftsmanship and athleticism. While there’s certainly a whiff of limousine essence in the GLS – especially in the well-appointed examples available on this test drive – the best seat in the house proved to be the one behind the steering wheel.

In terms of the luxury spirit of the GLS, the Tyrolean driving venue was appropriate. The newest 007 film, SPECTRE, was filmed on part of our route. And while the GLS didn’t quite make me feel like James Bond, I could certainly see myself cast in the role of his well-to-do yet out-of-shape relative (or, perhaps even more appropriately, Ernst Blofeld). The GLS did make me feel taller than I am, and more powerful. As a status symbol, you could do a hell of a lot worse than a comfy SUV bearing the three-pointed star. It’s abundantly clear that you’re meant to feel like some sort of no-limits, executive badass as a GLS owner, a conclusion that Mercedes cleverly drove home by showcasing the undeniably charismatic ute in such a magically cool setting.

For a gigantic Mercedes, it’s surprisingly easy to drive. Steering it through the alpine roads, I didn’t feel like I was trying to herd a bull through mud. In comfort mode on normal roads, it is an effortless drive. The driving assistance is pretty slick – especially the semi-autonomous driving of the optional Distronic Plus – and offers a little bit extra peace of mind when aiming the hefty GLS down the highway. Even in the hills, the transmission did a fine job of picking gears seamlessly while still leaving power on reserve. The suspension offers a stable ride, but it doesn’t feel particularly airy or spongy. When you feel anything at all, it's a sense of the car working to keep you level rather than just soften the bumps. Of course, there’s a little roll side to side, but I noticed it more as a passenger for the first few minutes, and forgot all about it once I got behind the wheel and in subsequent turns in the right seat. The optional Active Curve System roll stabilization is a welcome feature in a vehicle like this.

In Sport mode, things get even better. The steering, though tangibly boosted, feels smart. There’s a little room for play in dead center, but dial in a little input, and it weights up progressively, offering a nice snappiness with a few degrees of turn-in. The rest of the driving mechanics worked harmoniously, too. Gearshifts are quick and appropriate, with good response to throttle input. The paddle shifters are a nice touch, especially in the hills. Heading downhill into a tight corner, digging into the brakes offers a refreshingly ample amount of feel into what is going on between the rubber and the road regardless of the selected mode.

The steering, though tangibly boosted, feels smart.

The one drawback in navigating around the hills was in the forward vision. The beefy A-pillar takes up a lot of visual real estate when what you’d rather be seeing is what’s coming around the inside lane. Despite this one small niggle, though, vision was rather good. The large windscreen and side windows offer a good look at your surroundings, while the oversized side mirrors (and, to that effect, the driver assistance features) helped apprise me of everything outside of my forward view. Dicing through traffic when there are multiple lanes is a painless procedure, minimizing any of the usual anxieties in such driving situations. Additionally, the navigation system is very good, offering clear (and polite) instructions with no hesitation or equivocation – particularly helpful when traversing foreign roads. I could get used to this whole “confidence” thing when it comes to large vehicles.

The GLS is plenty potent, too. Putting the hammer down in the GLS550 results in exactly the sort of cannon shot you want from its biturbocharged 4.7-liter V8. Offering 449 horsepower and 516 pound-feet of torque going to four wheels, it takes off eagerly regardless of the road surface. While I didn’t perform proper 0-60 testing on the wet Tyrolean tarmac (and official figures haven’t been published), I can say that while the accelerative punch isn’t neck-snapping, the GLS makes mincemeat of any other car you need to pass when the road straightens out long enough. It also rewards you with a nice beefy engine sound (not too loud, of course) and the telltale and titillating whoosh of the forced induction. All this makes overtaking on a two-lane highway a very satisfying maneuver.

The GLS350d was no slouch, either. The lower-revving turbocharged six-cylinder climbed the steep grades smoothly and with aplomb. While the words “German” and “diesel” may bring up some negative connotations for some, I think the more discerning among us should be glad to see this greaseburner coming to our shores. I suspect more of us will be as fuel economy figures become available.

In addition to dominating the roads that traverse through the cozy Austrian burgs, icy, rocky wilderness, and cheery ski resorts, we had the opportunity to drive a closed mountain pass smothered in ice and snow above the village of Hochgurgl (try saying that with a mouthful of knödel). Complementing the Individual, Sport, and Comfort modes, the GLS is equipped with a Slippery mode for just such occasions. While my brain told me that by speeding across the frozen pass in a line of GLSs, I was putting my life in danger, the results were less dramatic. The car easily tackled frosted downhill hairpins without drama. Accelerating out of turns, the GLS showed impressive stability in the snow, and nobody ended up sliding off the side of the mountain.

Off-Road mode is also a standard setting on the rotary dial, and Off-Road+ is available as an option. While we didn’t get the opportunity to blaze our own trails in the GLS, those who wish to do so with the Off-Road+ setting will have extra ride height, appropriate suspension tuning and gear programming, and a center differential lock for when things get hairy. Want to ford a river? If it’s no deeper than two feet, it should be a walk in the (national) park.

Effortless driveability is its strongest and most refreshing quality. No bull.

Bringing all your gear shouldn’t be a problem, either. Fold both rear rows flat, and there’s 93.8 cubic feet of room for all your belongings. Dropping just the third row gives you a total of 49.4 cubic feet. If you need to fill the wayback with a sixth and/or seventh passenger, you’re limited to 16 cubic-feet of cargo space. In that case, it would make sense to take advantage of the GLS’s 7,500-pound towing capacity.

While the GLS may not look like much more than a slight makeover of the GL, the newly named SUV is well executed. It feels up to date both in its presentation and its abilities. It is undeniably stately without being stuffy or overwrought. Its built-in technology, particularly of the passive variety, makes it accommodating and approachable, and not overwhelming for the tech-averse. It’s highly capable, even in the dramatic setting of the Tyrolean Alps. Mostly, though, the GLS makes life easy on the driver. Its effortless driveability, at least to me, is its strongest and most refreshing quality. No bull.

First Drive: 2017 Mercedes-Benz GLS
 
It's not bad. Personally, I like the refresh and should do for a few more years till the next GLS comes in. While I don't think the interior is as "dated" as some say the W212F E-Class suggest it to be, it's certainly still looks a tad behind where the current MB design language is headed. Nevertheless, looks cozy and ready for the road trip to the ski resort!

But that price for the GLS550! Yikes! Noticeably more expensive than the GL. That's what the "S" stands for.

S-Class price!
 
The latest video was released. WOW. Mercedes-Benz engineer David teaches Der Landgraf how to drive the GLS in soft sand dunes. It's a standard GLS in OFFROAD 1, with deflated summer tires, AIRMATIC up one notch, and ESP must be OFF. Requires driving with full throttle in second gear frequently for extended times. Keep the momentum, or get stuck. Great vid. Although some caution may be advisable, as it may make it look easier than it is. Also, PreSafe may trigger from time to time, and tighten the seatbelts. :)

2017 Mercedes-Benz GLS-Class Review
More to it than just a name

G-whiz, Mercedes-Benz has finally given its lineup of SUVs logical names. The list now reads GLA, GLC, GLE, and GLS to align with the A-, C-, E-, and S-Class sedans, coupes, and wagons. Their common “G” is inherited from Mercedes’ G-Wagen, the popular and hot-selling Geländewagen, a favorite of the moneyed and militaries for more than three decades.

As with some of the well-to-do set, the GLS takes on the new model moniker with a facelift and a little rework out back. With just a glance at the SUV’s nose, there was never any doubt the GLS is a Mercedes, but now it’s a bit more in your face. The star is larger with a bright surround, while the horizontal slats are slotted. Headlamps take on a somewhat feline look, and the scoops below them are reshaped. You have the option of a prominent chrome chin or no chin at all with just a large, black intake.

By comparison, the rear alterations are minor, a bit of work on the bumpers and making the taillights LEDs. You can spiff up the exterior with the likes of optional running boards and AMG alloy wheels.

With these changes, the 2017 Mercedes-Benz GLS is more imposing, as you’d expect for what Mercedes boasts is “the only full-fledged seven-seater in the European premium SUV segment.”

To get a sense of its size, consider: the GLS550 is 1.9 inches shorter, 1.6 inches lower, and 2.5 inches narrower than a Cadillac Escalade on a wheelbase that is 5.1 inches longer than the Caddy’s. The German is 262 pounds lighter compared to the American SUV.

Those seated up front who know the old GL/GLS will find revisions, such as a center console updated with the possibility of a touchpad, while the 8-inch screen sits about right: high and just below the line of sight and with no serious glare problems. All this is in a nicely luxurious setting, with seats that have something of an overstuffed look to them, just enough brightwork to be attractive and not gaudy, plus a variety of materials and trims.

GLS drivers will find themselves behind a new three-spoke steering wheel, and should they be the sort who loves to push buttons and use switches, the interior layout will be pure heaven: We counted around 80 possible controls to manipulate. Some will see this as all the features they could want within easy reach. Others might find the layout a sea of similar size and color buttons with a typeface that’s a bit too small.

While the GLS will handle seven passengers, the interior is also designed to be a utility worker. Both rear row seatbacks are split, the way-backs folding electrically. The second row is divided 40/60, the seatbacks also foldable for a flat-load floor. With just the third row down, carrying capacity is upped to 49.4 cubic feet, but drop the second row too and you have 93.8 cu ft.

We recall when the diesel engine option upped a new car’s price, but the GLS350d is the least expensive in the lineup at $67,975. This diesel is a 3.0-liter, 24-valve turbo V-6 with 255 horsepower at 3,400 rpm and 457 lb-ft of torque between 1,600 and 2,400 rpm. Like any good modern diesel, it is both smooth and quiet. Inside you won’t hear the traditional diesel clatter. Stand next to the GLS350d, and the sound is so subdued it could be coming from an old-fashioned diesel car parked four or five parking slots away.

Mercedes pegs the diesel’s 0-60 time at 7.7 seconds, which in historical terms means this luxo SUV will outrun a classic 1956 Mercedes-Benz 300SL Gullwing. If you start from a standstill and nail the throttle, there’s a momentary pause followed by a momentary run-up of the turbo, and then the tach needle leaps to just past 4,000 rpm, the gearbox upshifts, and the needle whips to the right again. It’s fun and enough to make you chuckle.

There are two gasoline-fired versions offered, the GLS450 at $69,625 and the $94,775 GLS550. The 450 also has a 3.0-liter V-6, here with a pair of turbos, and 362 hp at 5,250-6,000 rpm and 369 lb-ft of torque from 1,800 to 4,500 rpm. Opt for the GLS550 with 4.7-liter twin turbo V-8 and get 449 hp at 5,250-5,500 rpm and 516 lb-ft of torque between 1,800 and 3,500 rpm.

Expect 60 mph in 6.5 seconds with the GLS450 and 5.2 driving the GLS550. We have mileage numbers of 17/22 mpg city/highway for the 450, while the EPA is yet to announce numbers for the other two. All of the models have a nine-speed automatic, 4MATIC all-wheel drive, and a top speed electronically trimmed to 130 mph.

Also on the standard equipment list is an air suspension plus electronic aids that have your back if you are sleepy, in a strong crosswind, nailing the brakes, or about to have a crash. Optionally they can also help you maintain your distance from the vehicle ahead, detect pedestrians, watch for cross traffic, help you parallel park, keep you in your lane of traffic, check your blind spots, and clean your windshield without all the messy spray thanks to Mercedes’ Magic Vision Control wiper system.

In more baby steps toward autonomous cars there are the connectivity capabilities of Mercedes Me Connect. This helps with everything from emergency needs to Remote Online, which uses your cell phone to keep you in touch with any number of elements. The system can, for instance, tell you where you parked your GLS, or how about this: You’re having dinner in Paris, and you suddenly wonder — as you often have — what the tire pressures are. Are the windows down? No need to worry, the answers are a phone call away.

We have a hard time imagining a GLS being used off-road, but there is an Off-Road Engineering option. This involves the intervention of the transmission and center differential for low-speed driving and gives the air suspension the ability to provide a 12.5-inch ground clearance and ford streams up to a depth of 23.6 inches. There’s a wisecrack here about breaching the fountain in front of a Nordstrom’s, but we’re not going there.

All these features come in handy when you’re just cruising, something the GLS does with aplomb. There’s a smooth, quiet ride, a comfy ambiance, and an excellent sound system.

Should you get on a twisty two-laner and want to enjoy the GLS’s other character, it can be rather satisfying. Remember you’re sitting tall in a large, 5,578-pound vehicle that wasn’t intended for Lewis Hamilton or Nico Rosberg. Still, this big boy can be enjoyable. For non-slippery surfaces you have the option of Sport, Comfort, or Individual settings for the suspension. We found it best to just go with the Sport setting for all occasions, city or country, for ride or roughhousing. Steering effort suits the occasion, and while the GLS leans a bit more than we’d like, it’s all fun and quite controllable.

We’ve already mentioned prices, but those are only starting points. For instance, the GLS350d we tested came in at $76,100, and we’d hate to have to delete any of the optional features. The GLS550 rounded out to a little more than $102,000. The option list is, to say the least, extensive and tempting.

Mercedes tells us the non-diesel GLS models will be in dealerships later this spring while the diesels are on tap for summertime.

G-whiz.
