The 2015 Mercedes M-Class has been spied wearing less camouflage than ever before.

Caught undergoing testing in Germany, the facelifted model has a familiar design but adopts a new front bumper and a more prominent two-bar grille. The changes are less noticeable out back but apparently include a new rear bumper and revised exhaust tips.

Our spies couldn't get close enough to snap interior photos but the model is expected to have revised trim and an updated infotainment system.

Engine options will likely carryover but the model could be offered with a new twin-turbo 3.0-liter V6 engine that produces 333 PS (245 kW) and 480 Nm (354 lb-ft) of torque. There have also been rumors about a new hybrid variant but nothing is official as of yet.
