2020 Mercedes-Benz GLS-Class SUV Review: Top Dog
As Mercedes-Benz's largest and most luxurious SUV, the brand new GLS-Class has a lot to prove. It replaces an outgoing model that had a trunk full of awards and accolades, so it's safe to say that the pressure is on. The redesigned SUV is bigger and more modern than its predecessor, allowing for even more practicality and comfort than before. Shoppers have the choice between a turbocharged 3.0-liter inline-six and a twin-turbo 4.0-liter V8, both equipped with EQ Boost and delivering expert performance. Yes, this SUV is stacked to the rafters with luxury and comfort, but when you're up against the equally esteemed BMW X7, there isn't an obvious champion.
What's the Price of the 2020 Mercedes-Benz GLS-Class SUV?
Two models make up the GLS-Class lineup. The entry-level model is the GLS 450 4MATIC that has a starting MSRP of $75,950. Climbing the next rung of the ladder to the GLS 580 4MATIC, the top of the range SUV bears a hefty $98,800 price tag. The base model is slightly more expensive than the entry-level X7's $73,900 asking price, but the apex models in both lineups are similarly priced. All prices are exclusive of the $995 destination and handling fee.

2020 GLS-Class SUV Performance
Handling and Driving Impressions
It comes as no surprise that regardless of which model you choose, a truly plush and compliant ride awaits you. This is mainly thanks to the air suspension with an adaptive damping system that comes standard on both GLS trims. Sensors and a whole bunch of complicated technology allow damping characteristics to change depending on the road conditions as you go along. Essentially, this keeps the car level and confident, regardless of the terrain. The result of the adjustable and intuitive suspension is a delightfully cushy ride, and the GLS SUV sails across undulations. Its occupants are none the wiser, and the driver doesn't have to sacrifice on handling dynamics for the sake of comfort. Driving the SUV is a far more engaging experience than one would expect, and this is especially true for the V8-equipped version. The burly Mercedes has a hidden superpower. Agility. Its curve mode setting mitigates body roll, and on the off chance that you venture off-road, the GLS won't disappoint there either. All-wheel-drive is standard on both models, and both engines are sprightly enough for lively city-driving. They're also great at overtaking slower cars and merging onto the highway at higher speeds thanks to ample power offered at the top end.

Verdict: Is the 2020 Mercedes-Benz GLS-Class SUV A Good SUV?
The Mercedes-Benz GLS-Class SUV is an excellent offering in its segment and excels in all the areas that matter most for a strong victory against most rivals. For starters, both powertrains offer outstanding power figures, and though the base engine returns fuel economy figures that fall slightly behind its rival from BMW, the more powerful V8 found in the GLS 580 came back with impressive EPA estimates that are slightly better than the more powerful 4.4-liter V8 found in the top of the range X7 lineup. Power and frugality rarely come as a package deal when it comes to engines, but the GLS manages to blend the two. Aside from its performance and relatively light sipping, the inside of the SUV is a heavenly, plush masterpiece that's complemented perfectly by state of the art technology in the form of two large screens that combine the instrument cluster and infotainment in a surprisingly easy-to-use manner. The whole experience behind the wheel of any GLS is likely to put a smile on the faces of even those who are difficult to please.
What Mercedes-Benz GLS-Class SUV Model Should I Buy?
Unless you're an avid performance junkie, the GLS 450 4MATIC will treat its driver just fine. The smaller engine provides ample power for the daily commute and then some, rendering the GLS 580 pretty irrelevant unless you truly need the extra power. We'd recommend opting for the base model and using the extra cash for additional packages like the notable Driver Assistance Plus Package that adds a fully comprehensive safety suite to the SUV. For some extra attitude, opt for the GLS with the 21-inch wheels and the designo Cardinal Red metallic paint. With all of these options added, the final price comes up to $85,520, this is with the Tartufo leather upholstery and the Energizing package added to the mix, as the Driver Assistance package can't be added without them.
2020 Mercedes-Benz GLS-Class SUV Comparisons
2020 Mercedes-Benz GLS-Class SUV vs Mercedes-Benz G-Class
The boxy G-Class adds tens of thousands of dollars onto the price of the GLS-Class SUV, and a whole lot of status points with it. Only the most elite can be seen trawling about in a six-figure lunch tin, so this is essentially the iPhone of bigger Mercs. The inside of the G550 is modern and also integrates two digital screens rather seamlessly. The main difference between the interiors is that the G-Class gives a considerably more off-road feel, and the inside of the GLS-Class is slightly more refined. Aside from appearances, the G-Class is home to a twin-turbocharged 4.0-liter V8 engine that punches out 416 horsepower as standard, but the higher trim level of the GLS-Class has a more powerful 483 hp engine for a considerably more affordable price. It's likely that these two offerings from Mercedes-Benz will appeal to very different people, but all things considered, the GLS-Class SUV is the better buy.
2020 Mercedes-Benz GLS-Class SUV vs BMW X7
The GLS-Class manages less powerful outputs of 483 hp and 516 lb-ft in comparison to the xDrive M50i's 523 horses and 553 lb-ft. The former manages to deliver a better interior, though opinions on that will depend on personal preference. The GLS SUV has better road manners than its counterpart, and also offers more interior space and a much bigger trunk than the BMW. The Merc does fall behind in terms of fuel economy with base engines considered and the base model in the X7 lineup returns considerably more frugal EPA estimates. The X7 offers excellent power outputs without the sacrifice of fuel economy, but the Merc offers a better interior with much more space. The better SUV will ultimately depend on what you're hoping to get out of one.
