2015 Mercedes-Benz GLK Spied

The next Mercedes GLK should grow slightly larger to accommodate the smaller GLA crossover.

We recently spied the next-generation Mercedes-Benz GLK-Class crossover testing and, although the prototype appears to be in the early stages of development, the new GLK appears slightly larger than the current generation. The upcoming Mercedes-Benz GLK-Class will be based on the redesigned C-Class, which will most likely make its debut at the Detroit auto show this January.

We can’t see much under the disguise, but the overall shape of this GLK prototype looks more rounded than the blocky lines of the current GLK-Class. Mercedes could be going for a more crossover-like appearance for this next GLK to better slot in above the smaller forthcoming GLA crossover, which is based on the front-wheel-drive CLA sedan.

Since the CLA and GLA are replacing the C-Class and GLK as the smallest Mercedes-Benz offerings in the U.S., respectively, both C-Class and GLK should grow slightly larger for the next generation. The next GLK’s larger footprint should mean for greater passenger and cargo space over the current version, which is slightly smaller inside than competitors like the Audi Q5 and BMW X3.

Like the current Mercedes-Benz GLK-Class, the new version should offer a choice of rear- or four-wheel-drive along with a diverse lineup of gasoline and diesel powertrains. In the U.S., we expect to see a similar powertrain lineup as the current GLK, which offers a 3.5-liter gasoline V-6 in GLK350 models and a 2.1-liter turbodiesel four-cylinder in GLK250 Bluetec models. The new GLK could also use some of the new engines expected for the 2015 C-Class, which include a Nissan-developed 2.0-liter turbo four and a 3.0-liter twin-turbo V-6.

Look for the upcoming Mercedes-Benz GLK-Class to debut sometime next year following the introduction of the 2015 Mercedes-Benz C-Class in early 2014.
