Mercedes has announced two new additions to the GLK lineup, the GLK 250 CDI 4MATIC BlueEFFICIENCY and the GLK 220 CDI BlueEFFICIENCY.

Mercedes has announced two new BlueEFFICIENCY additions to the GLK lineup.

The first model is the GLK 250 CDI 4MATIC BlueEFFICIENCY with 150 kW (204 hp) and 500 Nm of torque. Boasting the title of the "world's most powerful four-cylinder diesel engine for an SUV," the 250 CDI BE accelerates from 0-100 km/h in 7.9 seconds before hitting a top speed of 213 km/h (132 mph). Fuel consumption comes in at 6.7L/100km (35.1 mpg), while CO2 emissions are 176 g/km.

If that isn't efficient enough for you, Mercedes also offers the new GLK 220 CDI BlueEFFICIENCY with 125 kW (170 hp) and 400 Nm of torque. Stripped of all-wheel drive and the 7G-TRONIC automatic transmission (it's an option), the 220 CDI BE consumes between 6.0L/100km (39.2 mpg) and 6.4L/100km (36.8 mpg). Other specs include a CO2 emissions rating of 158-168 g/km, a 0-100 km/h time of 8.5 seconds, and a top speed of 205 km/h (127 mph).

Oddly enough, Mercedes hinted that both engines could be coming to North America by stating they have "...the potential to fulfill the EU6 limits as well as the BIN 5 requirements in the USA."

While the styling is virtually identical to the GLK 350, both BlueEFFICIENCY models have been equipped with "weight-optimized" alloy wheels and 235/60 R 17 V low-rolling resistance tires.

Besides the engines, Mercedes has also announced several new equipment options for the GLK lineup. Items include KEYLESS GO (passive entry), a rearview camera, an 'Intelligent Light' package with LED daytime running lights, and 'ARTICO' synthetic leather seats. The biggest addition is an AMG sports package which features new front and rear aprons, 20-inch twin-spoke AMG wheels, and additional chrome detailing.
