Introduced in 2006 as the company’s first full-size SUV, the Mercedes-Benz GL developed from a longer version of the ML into a model of its own with unique features and an AMG version. Just like the ML, which became the GLE, the GL was renamed to GLS in 2016. Part of the brand’s revised nomenclature, the GLS badge signals that this vehicle is the SUV equivalent to the S-Class. On the market since 2012 in its second-generation, the GLS is about to get a big overhaul for the 2019 model year. Alongside the redesigned SUV, Mercedes will also launch a brand-new version of the AMG GLS63. Already spotted on public roads, the performance SUV will arrive sometime in 2019.
