The GLS 450 is a luxury cruise liner on wheels, but it's thirsty and tight in the back.
The 2025 Mercedes-Benz GLS 450 defines itself with a cabin that feels like a first-class lounge at 30,000 feet. Every surface is a tactile delight, and the tech is seamlessly integrated, making it a true joy to interact with. On the road, the GLS glides with a refined grace that belies its size, and the engines provide silky power delivery that makes highway merging a breeze. What surprised us was how nimble it feels for such a large SUV, almost shrinking around you as you navigate city streets or winding roads. However, the third row feels more like an afterthought, best suited for kids or short trips. If you're in the market for an SUV that prioritizes luxury and technology, and you're not too concerned about fuel efficiency or third-row space, the GLS 450 deserves a spot on your list.
