Small crossovers are all the rage these days, one of the fastest-growing sales segments in the U.S. market at all price points. From the less-expensive Hyundais and Kias at the bottom end to the high-priced luxury versions like the 2013 Mercedes-Benz GLK, Americans seemingly can't get enough of them.
We reviewed the newly restyled 2013 GLK350 last summer, with News Editor Jennifer Geiger finding it a bit compromised in V-6 form, with a smallish interior, fussy audio and navigation system, and styling that's aimed at a male demographic (making the vehicle's public debut as Samatha's ride in the "Sex and the City" movie somewhat odd).
But now Mercedes-Benz is introducing the second powertrain for the GLK, with the arrival of the GLK250 Bluetec diesel, making the GLK the most fuel-efficient luxury crossover in the country. That suddenly makes the little trucklet a bit more interesting.
