This advantage is further amplified in the 2027 model, thanks to a thoughtful 2.4-inch increase in wheelbase. This seemingly modest extension translates directly into tangible benefits, notably improving legroom for occupants in both the first and second rows, ensuring enhanced comfort on longer journeys.
Headroom, a common concern in many modern SUVs, is also significantly improved, partially due to a standard panoramic sunroof. For an even more spectacular experience, the optional Sky Control version of the sunroof allows occupants to switch the glass from transparent to opaque in under a second with the touch of a button, providing instant shade or privacy. At night, a truly magical touch comes to life: 158 precisely embedded three-pointed stars within the glass illuminate, creating a celestial ambiance that transforms the cabin into a truly unique space, a hallmark of sustainable luxury automobiles.
The GLB’s enduring appeal as a family-friendly luxury SUV is its optional third-row seating, providing genuine seven-seat versatility. This feature remains a core selling point, offering flexibility for larger families or those who occasionally need to transport extra passengers. For 2027, the second-row seats now slide even farther forward, greatly improving access to the very back. While an average-height adult can technically squeeze into the third row, perhaps for short trips, it is unequivocally best suited for children, a realistic assessment that long-time users of compact three-row SUVs will appreciate.
Cargo space, a critical consideration for any SUV, also sees intelligent optimization. The EV model offers a generous 19.1 cubic feet with five seats in place, expanding further with the third row folded down (17 cubic feet). While specific capacities with the third row upright are not yet listed, it’s safe to assume space for a large duffel bag or grocery run. A surprising and highly practical addition to the EV is a sizable 4.5-cubic-foot frunk (front trunk), an often-overlooked feature that significantly enhances utility, surpassing even the frunk capacity of popular EVs like the Tesla Model Y. While specific hybrid cargo figures are pending, they are expected to be similar, minus the frunk.
