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 2015 GLK is Mercedes-Benz's classy and competent entrant in the compact-luxury SUV segment, where it competes with rivals like the BMW X3, Audi Q5 and the new Lincoln MKC. Where it stands out from nearly every competitor is with its angular design that clearly indicates its status as the little brother of the M-Class and GL-Class luxury SUVs. Until this year, the GLK was the smallest and youngest crossover SUV in the Mercedes family, but that changes with the arrival of the subcompact GLA. The 2015 GLK doesn't necessarily stand out for one trait, but it is above average in just about every facet. The BlueTEC diesel version, for example, earns up to 33 mpg, while standard and available safety systems are highly advanced.
