Mercedes-Benz is working on a mid-cycle update for the GLS-Class and a prototype has just been spotted.
The current-generation GLS-Class arrived on the scene in 2019 as a 2020 model, with the Maybach version arriving a year later. In Mercedes tradition, this mid-cycle update should be introduced for the 2024 model year, meaning a debut sometime next year is likely.
The prototype shows only light camouflage gear, meaning visual tweaks will be minor. We can expect a new front fascia and new internals for the lights at both ends. It also looks like the grille will be revised.
The interior of the GLS-Class will also receive some tweaks with this update. Our source suggests elements from the S-Class, like the steering wheel design, will make it into the GLS-Class. We should also see updated graphics for the digital instrument cluster and infotainment system.
It isn't clear what the plan is for the powertrains but a plug-in hybrid option is a possibility. The GLS-Class currently offers turbocharged inline-6 and V-8 engines in mild-hybrid configurations.
The most powerful is the GLS 63 from AMG, which packs a twin-turbocharged 4.0-liter V-8 in a mild-hybrid configuration. Peak output is rated at 603 hp and 627 lb-ft of torque.
