2026 Mercedes-Benz GLB spied doing hot laps

The second-generation Mercedes-Benz GLB has been photographed doing laps of the Nurburgring as it undergoes testing.

Although the car is clad in camouflage, we can see the GLB’s overall silhouette doesn’t diverge too far from today’s car, with the passenger cell being predictably blocky and upright in order to maximise interior room. As with today’s car, the new GLB will likely be offered with a third rows of seats.

Up front, though, it seems like the rectangular headlights have been replaced sleeker units, not dissimilar to the ones fitted to the CLA, with which the GLB shares the Mercedes Modular Architecture (MMA). Like the CLA, the GLB could also feature a light bar or black plastic strip linking its headlights.

Along the side we can see new flagpole-style wing mirrors, and flushing-fitting pop-out door handles. There’s plenty of false body work underneath the camouflage wrap, so we can’t tell if the stepped rear quarter windows are retained for the GLB’s sophomore round.

At the rear the disguise team has cheekily fitted stickers of the tail-lights from the third-generation Smart ForTwo. To the side of these are the arc of LED light tubes bending down and around, which marks quite a departure from the current GLB’s thin strip of lights.
