For 2013, the Mercedes-Benz GLK line expands to include a new BlueTEC diesel-powered GLK250 (arriving mid-2013). The GLK350 gets a new 3.5-liter V6 with better power, response and efficiency. There's new front- and rear-end styling, a redesigned interior, improvements to the power steering and some new equipment offerings.
The 2012 GLK350 has some big shoes to fill as the junior member of the Mercedes-Benz SUV family. To the delight of its larger siblings – the Mercedes M-Class and GL-Class – the compact GLK offers the modern styling, upscale amenities and advanced safety features one should expect from a luxury vehicle. Developed on Mercedes-Benz's best-selling C-Class platform, the 2012 GLK combines the comfortable ride quality and enticing technology of the C with the versatility of a small SUV.
