Facelifted GLK prototype spied in the U.S. desert without a gear shift lever on the center console.

These are the latest spy shots of the upcoming facelifted 2012 Mercedes-Benz GLK, taken as the model undergoes hot-weather testing in the desert region of the United States.

This time our spy photographers manage to get up close and snap some interior shots too of the new GLK. Noticeably absent is the gear shift lever on the center console which has now been replaced (at least for the prototype) with a stalk on the steering wheel. But perhaps that's just a result of the testing setup for the vehicle. The new instrument panel looks more like a permanent change.

We also get a close shot of the new headlights with embedded LED indicators and another look at that enlarged grille.

Expected to power this facelifted GLK will be a series of engine options including the GLK 350 BlueEfficiency with a 3.5 liter V6 doling out 306 PS (225 kW / 302 hp) and 370 Nm (273 lb-ft) of torque.
