2020 Mercedes-Benz GLS 450

From Edmunds:   The 2020 Mercedes-Benz GLS represents a new generation for Benz's biggest luxury hauler. The outgoing Mercedes GLS was getting long in the tooth, especially when compared to models from BMW, Audi and more. But for 2020, it's new, and we mean totally new. For starters, the GLS' chassis is longer and the body more aerodynamic, which translates into more room and a quieter, more efficient ride. And unlike most three-row SUVs, the new GLS can comfortably seat adults in all three rows. It also comes standard with an adjustable air suspension that offers a supple ride. Both of the GLS' available engines are responsive and powerful. All-wheel drive is standard, and when equipped with the Off-Road package, the GLS features true low-range gearing for when the trail gets tough. Few SUVs are as good at combining off-road capability, cargo-carrying flexibility and passenger comfort as the Mercedes-Benz GLS. But the cherry on the cake for 2020? It comes with MBUX, Mercedes' latest infotainment system and one of the best in the business, and envelops passengers in a quiet and comfortable ride. The GLS seals the deal as one of our favorites.   Performance 8.5/10 How does the GLS-Class drive? The raw numbers are frankly astounding and, on paper, suggest a much smaller and far sportier vehicle. A 0-60 mph time of 6.2 seconds with the base turbo inline-six is more than adequate. It feels strong too, no matter what situation you're driving in. The engine's mild hybrid system improves both performance and efficiency and makes for super-smooth power delivery. Occasional hiccups from the transmission are our biggest complaint. Stops from 60 mph came in just 105 feet, one of the best results we've seen from any SUV. That's genuine performance-car territory. Part of that is down to the no-cost summer tires, which help provide plenty lateral grip too. The steering is light and makes the GLS easy to maneuver in a parking lot or in traffic. Comfort 8.5/10 How comfortable is the GLS-Class? Mercedes-Benz nailed it when it comes to on-road comfort. The seats are supportive and hugely adjustable, and optional massagers help keep you comfortable after a few hours behind the wheel. The heated and ventilated seats work well, and the automatic climate control quickly evens out cabin temperatures. There's little intrusion from the outside world, with just a bit of road noise on rough pavement. With the optional E-Active Body Control suspension, ride quality is excellent. It's smooth and composed, ironing out most road imperfections without floating or wallowing. Large wheels can hurt ride quality in many SUVs, but our test vehicle with optional 21-inch wheels didn't seem fazed. Interior 9.0/10 Hows the interior? The GLS' interior is excellent from almost every perspective. The driving position is upright and commanding, but you always feel comfortably ensconced in the GLS. There's plenty of room in all three rows; 6-foot-plus adults can fit comfortably in the easy-to-access third row. The large windows help all-around visibility and make passengers in the rear feel less claustrophobic. The controls are all well placed and easy to reach, but there's a lot of them and the small text means you have to take your eyes off the road until you work up the muscle memory. Separating the seat controls between the door and the infotainment system is a bit frustrating too. Technology 9.5/10 Hows the tech? Mercedes' infotainment system is a marvel and benchmark for the class even if the learning curve is a bit steep. The navigation system in particular is a standout, and the augmented reality overlay and turn-by-turn directions in the instrument cluster and head-up display are compelling reasons to ditch the apps on your phone. That said, both Apple CarPlay and Android Auto are standard. All three rows have USB-C ports, and a standard wireless charging pad sits in front of the cupholders. The driver aids are equally impr
