Five-Point Inspection: 2013 Mercedes GLK 250 BlueTEC

2. Impressive Output Any Way You Slice It

Engine size aside, the output from this vehicle is remarkable. A full 369 lb-ft of twist comes on at 1,600 rpm thanks to a pair of dual sequential turbochargers. You’ll rarely feel the powertrain running out of breath with Mercedes’ seven-speed automatic in play. It’s more than enough to deliver potent acceleration unbecoming of such a puny four-cylinder.  The mill seems milder at highway speeds, but with 200 hp and the aforementioned torque offer plenty of “go.”
