“The familiar 3.5-liter gasoline V-6 gets direct fuel injection and a robust output increase, from 268 hp to 302, and 258 lb-ft of torque to 273. However, the bigger news is the GLK250 BlueTec diesel, available in the U.S. only with 4MATIC four-wheel drive. With a debut set for early 2013, the diesel's pricing hasn't been announced, but Mercedes execs hinted that it should slot in above the base rear-drive GLK350 ($37,995) and below the GLK350 4MATIC ($39,995). The gas-powered models will be available later this summer.”
“The 190-hp diesel makes distinctly diesel noises and vibes, although it's a distant, well-muffled clatter without a lot of tick-ticking in it, thanks to those pricey (and quieter) piezo injectors. As advertised, the max of 369 lb-ft torque is available nearly instantly (from 1600 rpm to 3000 rpm), and the GLK250 pulls away from a stop with the kind of assertive, confident thrust that we've come to expect from modern turbo-diesels.”
“No major changes are notable in the GLK's composed handling. This is a compliment, in light of the switch to electromechanical steering, which gives precise helm control if not lively feedback and lets you cut clean ellipses through corners with good grip and body control.”
