Updated Mercedes-Maybach GLS-Class Spotted in Testing

Mercedes-Benz is continuing to refine its flagship luxury SUV, preparing a second update for the GLS-Class, which originally debuted in 2020. While the 2024 facelift introduced subtle design tweaks, the 2027 model promises more significant changes. Spy photos of heavily camouflaged prototypes suggest that Mercedes-Maybach is working on substantial refinements to keep its ultra-luxurious SUV ahead of the competition.

What We Know So Far

For the U.S. market, the Mercedes-Maybach GLS-Class is available exclusively as the GLS 600, featuring a 4.0-liter twin-turbo V8 with a 48V mild-hybrid system. This setup produces 550 horsepower and is paired with a 9-speed automatic transmission and all-wheel drive.

Mercedes-Benz has yet to confirm technical upgrades, but given the proven reliability and power of the current powertrain, any changes are expected to focus on refinement and efficiency rather than drastic performance shifts.

What makes this update particularly notable is that Mercedes-Benz rarely performs a second refresh within a single model cycle. However, with slowing demand for electric vehicles, the company is reassessing its long-term strategy and extending the lifespan of internal combustion engine (ICE) models.

Originally, Mercedes-Benz aimed to go fully electric by 2030, but recent statements indicate that ICE-powered vehicles will remain available beyond this deadline, signaling a more flexible approach to future mobility.

A Broader Strategy for Luxury SUVs

Alongside the GLS-Class, the Mercedes-Benz GLE-Class is also undergoing testing for its own update. This suggests that the German automaker is taking a comprehensive approach to modernizing its luxury SUV lineup, ensuring continued competitiveness in an evolving market.

With Maybach’s commitment to ultra-luxury refinement, the upcoming GLS update is expected to elevate comfort, technology, and design, solidifying its status as the pinnacle of luxury SUVs.
