What is it? The Vision GL420 Bluetec offers a first look at the next-generation diesel version of the GL-Class SUV. Unlike the current GL320 CDI diesel that Mercedes currently offers, the future Bluetec version will meet the stringent Bin 5 emissions standards, making it eligible for sale in all 50 states. The 4.2-liter V8 in the concept generates 515-lb.-ft. of torque and 290 hp, with a claimed range of nearly 600 miles on one tank of diesel fuel.
What is new or notable: The Bluetec engines in the upcoming Mercedes-Benz vehicles, as well as with their partners Audi and Volkswagen, use the AdBlue urea solution to meet EPA Tier II emission standards for nitrogen oxide. Mercedes announced that it intends to sell AdBlue versions of its Bluetec R-, ML-, and GL-Class models.
