Caught undergoing testing in Germany, the updated crossover features modified bumpers, restyled headlights and an enlarged grille.

Our spy photographers have snapped the first pictures of the 2012 Mercedes GLK facelift.

While the crossover is moderately camouflaged, we can see it will feature modified bumpers, restyled headlights (with LED indicators) and an enlarged grille.

Under the hood, there will be several new engine options. Details are limited, but the GLK 350 BlueEfficiency should adopt a 3.5-liter V6 with 306 PS (225 kW / 302 hp) and 370 Nm (273 lb-ft ) of torque.

The 2012 GLK will be unveiled sometime next year, so stay tuned for additional information.
