The Mercedes-Benz GLK quickly gained a reputation for its bold styling and sporty handling, but when it debuted, its 16 city, 22 highway fuel economy left quite a bit to be desired in the area of fuel economy. With the direct-injected 3.5-liter V-6 engine being added for 2013, both city and highway fuel economy got a significant 3 mpg bump, but the most frugal of GLKs to date has now arrived, and delivers a compact-like 33 mpg highway, thanks to the new 200-hp, 369 lb-ft 2.1-liter turbodiesel I-4 in the 2013 Mercedes-Benz GLK250 Bluetec.
The GLK250 carries a $1500 premium at first glance, but it's actually $500 cheaper than a comparably-equipped GLK350 because the GLK250 comes standard with Mercedes' 4Matic all-wheel-drive system, a $2000 option on the GLK350. That brings the price of entry for the new diesel compact SUV to $39.495, including the $905 destination fee.
As usual, there are plenty of bundled and a la carte extras you can add. Adding the Premium, Multimedia, Leather and Lane Tracking packages, and 20-inch AMG accessory wheels, we were able to inflate that total by almost $20,000 to $58,125.. For comparison, the ML350 Bluetec starts at $52,175, but like its little brother, can go for substantially more once you start adding the extras.
