Mercedes-Benz GLS (X167)

The Mercedes-Benz GLS (X167) is the third generation of the Mercedes-Benz GLS full-sized luxury crossover SUV that began production in October 2019. It replaces the Mercedes-Benz GL-Class/GLS (X166).

Development and launch
The third generation X167 GLS debuted at the 2019 New York International Auto Show. It is launched in October 2019 in the United States and at the end of 2019 for Europe and rest of the world. The X167 is 7.7 cm longer and 2.2 cm wider than X166. The wheelbase is 6 cm longer, which increases interior space for the second row seats. Additionally, X167 GLS is first SUV from Mercedes-Benz to have fully electrically adjustable three rows of seats and to offer the optional six-seat configuration with captain seats for second row. The second and third row seats can be folded electrically flat with a touch of a button.

Mercedes-Maybach GLS 600 4MATIC
A first Maybach version of the GLS, the GLS 600 4MATIC, was unveiled at 2019 Guangzhou International Motor Show on 21 November 2019. The engine is a detuned version of the M177 V8 Biturbo found in the Mercedes-AMG GLS 63 4MATIC+, but with a 48-Volt mild hybrid system. Although Mercedes-Benz has registered both GLS 600 4MATIC and GLS 680 4MATIC nomenclatures, the latter was designated exclusively to the Chinese market due to the auspicious nature of number 8, closely associated with luck and wealth, as the manufacturer has done with Mercedes-Maybach S 680 (known as the S 650 in other markets). The GLS 600 4MATIC isn't based on the Mercedes-Maybach Vision Ultimate Luxury concept vehicle shown at 2018 Shanghai Motor Show. This version is the first time that a three-point star stand-up ornament affixed to the hood/bonnet on an SUV, rather than the large "jet-engine" three-point star filling up the grille space as found in every SUV from Mercedes-Benz since 1979.

Mercedes-AMG GLS 63 4MATIC+
The second generation AMG version of the GLS-Class, GLS 63 4MATIC+, was introduced at the same time as Mercedes-Maybach GLS 600 4MATIC. The 4.0-litre M177 V8 Biturbo is rated at 455 kW, making the GLS 63 4MATIC+ the most powerful GLS ever. The novel feature is the "reintroduction" of classical AMG monoblock alloy wheels, which were popular option in the 1980s and 1990s.

Due to its large size and negative environmental impact, Environmental Action Germany gave the car their Goldener Geier (Golden Vulture) award in 2020.

Recall
In March 2024, Mercedes-Benz recalled over 116,000 GLE and GLS cars, built from 2019 to 2024, due to a loose 48-volt ground cable that may not have been tightened properly during assembly. The ground cable is located under the front passenger seat that could pose a potential safety risk when the cables become hot.

Facelift
The X167 had a facelift in 2023.
