Why it stands out
The 2020 Mercedes-Benz GLS stands out as the roomiest vehicle in the Mercedes-Benz lineup, with three rows of seating for six or seven people and up to 94 cubic feet of cargo space. It is also positioned as a midsize SUV that blends the comfort and space of the S-Class luxury sedan with some off-road capability, which gives it a broader appeal than a typical family hauler. For 2020, Mercedes moved the GLS into its second generation with a curvier exterior, a wide-screened cabin, a stretched wheelbase, and a body that was just over 2.5 inches longer.
That redesign brought meaningful gains in technology and refinement. The 2020 GLS450 used a new 3.0-liter inline-six with 362 horsepower and 369 pound-feet of torque, paired with a 48-volt mild hybrid system called EQ Boost. Mercedes said that setup improved fuel economy to an EPA-estimated 21 mpg combined, up from 18 mpg in the 2019 model. Standard equipment was generous, including dual 12.3-inch displays with MBUX, navigation, a Burmester surround sound stereo, wireless charging, nine USB-C ports, power-folding third-row seats, power-adjustable second-row seats, and 19-inch wheels. Safety and convenience features were also a highlight, with blind spot assist, 360-degree cameras, adaptive headlamps, auto high beams, parking assist, Car-to-X communication, and Exit Warning Assist all included.
The GLS also has a practical side that helps explain its appeal. Mercedes built in a seating function that automatically adjusts the seat in front when part of the second or third row is folded, making it easier to load passengers or cargo without repeated seat shuffling. At the same time, the 2020 model is not without compromises: front headroom decreased, total cargo space shrank significantly compared with the previous generation, and the AMG Line Package could impede entry and exit. Even so, the 2020 GLS remains distinctive for buyers who want a large, luxurious three-row SUV with strong standard technology and a cabin designed around comfort and flexibility.

Love all the features and it can pull my camper no problem! Beautiful car with kinetic seats that are nice when on a long drive. Love how my phone integrates into the dash screen. It’s classy for business but heavy enough to be outdoorsy as welll. Great value and you can’t go wrong with a Mercedes.

I just purchased a 2020 GLS 450 with 18,000 miles on the clock and I LOVE it. Nothing beats Mercedes when it comes to quality of vehicle and service from the Mercedes team. I was able to get an extended 5 year/ 100,000 mile warranty, which to me was worth the extra money. My last Mercedes was a 2003 E 500. It was such a good car that I waited this long to replace it. That’s what you get when you buy a Mercedes.
