Mercedes Benz is adding two new BlueEfficiency variants to is compact GLK crossover. Both are powered by versions of Mercedes’ new 2.2-liter four cylinder diesel engine. The rear wheel drive 220 CDI gets the 170 hp variant while the all wheel drive 250 CDI 4Matic gets the more powerful dual turbo 204 hp unit.
The RWD 220 gets as much as 39.2 mpg (U.S.) combined on the EU driving cycle with CO2 emissions of 158 g/km. This model can get to 62 mph in 8.5 seconds. The more powerful AWD version cuts that acceleration time to 7 seconds while still achieving 35.1 mpg (U.S.) on the EU cycle.
Currently, the new GLKs are only being offered in Europe, but both can meet the EU5 and upcoming EU6 emissions standards. Best of all, they are also able to meet US Tier2 Bin5 standards so they could be sold in all 50 states. The BlueEfficiency models get lower rolling resistance tires, more aerodynamic (read: smaller) mirrors, underbody panels and electric power steering to optimize efficiency.
