Now that Mercedes-Benz has officially launched the 2012 M-Class, it’s time for the automaker to finish off the tweaks for its larger GL-Class crossover. It’s been many moons since Autoblog spy photographers have spotted the big GL out testing, but the prototypes are now back on the road, and it appears that a bit more of the matte camouflage has been stripped away.
We don’t expect things to change too much from the current GL, save the addition of some new headlamps and LED taillamps. If the M-Class is anything to go off of, we can expect that both gasoline and diesel engines will make their way to the United States, likely in the same GL350 turbo-diesel V8 and GL550 V8 guises that we currently have. For the V8 model, the old 5.5-liter naturally aspirated unit will surely be swapped out for the new twin-turbocharged 4.6-liter powerplant, found in the other 550-badged Mercedes-Benz models.
Look for the updated GL-Class to debut later this year.
