The 2013 Mercedes-Benz GL prototype has been spotted again, this time with less camo than before. Mercedes-Benz has been testing their new 2013 GL SUV for some time now, and our spy photographers have caught the elusive model again with even less camouflage than before. The prototype seen here is testing on some public streets in full view of our cameras.Starting with the 2013 GL\'s rear, we can see some new taillights along with a redesigned tail gate. The spoiler has been moved towards the top of the SUV, while on the front even more redesigns have taken place. The German brand has added a two-bar grille on the front-end, with the signature Mercedes-Benz three-pointed star fixed right in the middle. LED strips have been added on the front bumper and revised air intakes complete the redesign so far as we can tell.Under the hood, Mercedes-Benz will offer a wide array of powerplants for their 2013 model. We are talking the MOVE family of V6 engines with direct injection along with several twin-turbocharged V8 motors.In case you haven\'t noticed, these are the same engines sitting under the M-Class\' hoods. Check out the latest photos of the 2013 Mercedes-Benz GL and let us know what you think about the German automaker\'s latest offering so far for their SUV.
