Formerly known as the GL-Class, the 2018 Mercedes-Benz GLS-Class reflects the brand's belief that it's the S-Class of SUVs. Thanks to a bevy of year-over-year upgrades, the GLS-Class appears to have properly earned this designation, and it's one of the most desirable models Mercedes-Benz has to offer.
While styling cues and mechanical systems return unchanged, there's much more going on behind the scenes. The nine-speed automatic transmission available across the line (with the exception of the AMG version) is simply superb. There's also an upgraded infotainment system that features a large central display, a touchpad and an optional upgrade to Apple CarPlay.
The interior is typical GLS style, with premium vinyl upholstery and genuine wood trim and featuring a three-spoke steering wheel (a racy flat-bottomed version is available with the AMG model). The third row of the GLS-Class can even comfortably accommodate adult passengers. And thanks to smooth engines, and an even smoother suspension, the 2018 GLS is as quiet as GLs of the past.
The 2018 GLS-Class is available in three different trim levels, from the standard GLS 450 to the high-performance AMG GLS 63. In between lies the GLS 550, which adds the many premium options from the 450, then tacks on more — including wood steering-wheel inserts. There's even an Off-Road package available that, among other things, adds a dual-range transfer case and front underbody protection so you can choose the road less traveled.
Performance-wise, the GLS-Class drives with a considerable amount of agility, belying its massive size. The GLS 450's 3.0-liter twin-turbo V6 produces 362 hp and 369 lb-ft of torque, while the GLS 550's 5.5-liter twin turbo V8 produces 449 hp and 516 lb-ft of torque. Finally, the AMG GLS 63 drives the big SUV with 577 hp and 561 lb-ft of torque and sport-tuned suspension.
The new GLS-Class is well deserving of the S-Class designation because there really is no other SUV like it when it comes to luxury, driving experience and technology. Edmunds will help you find the right trim and packages — and the right price — to make the 2018 Mercedes-Benz GLS-Class yours.

GLS 550 4MATIC 4dr SUV AWD (4.7L 8cyl Turbo 9A)
Is this a car or a magic carpet? Truly it?s like an escalator that effortlessly lifts you along. We test drove and put a deposit on an Audi Q7. We didn?t want the stigma of a Mercedes and to hear comments from family or neighbors. My wife just wasn?t in love with the idea of the Q7 and neither was I. It was too small and lacked a spare tire. We finally said the heck with it and test drove the Benz. We knew immediately it was the right car for us and cancelled the Q7 order. I drive a Dodge Durango that is built on the same platform as the GLS. There is no comparison, the interior or the Benz is smaller because the body is made with more high-strength steel. This car is a vault and safety is my highest priority. I?m a cheapskate. But I will spend money for safety. Everything about this car is impeccable. The LED headlights amazing. Air suspension amazing, go off road and it raises the car 5 inches. Put it in sport mode and it keeps the car flat on winding roads. My wife is amazed by this car. She feels confident and assured. The only thing I don?t care for is the electronic interface and that is just a matter of reading the manual. I have no other complaints. It was expensive. But it is worth it to protect my family and to reward my wife for putting up with me. Test drive this car before you buy anything else. It is so easy and fun to drive.
