The GLK-Class debuted in 2010 as one of the least expensive Mercedes-Benz offerings on the market, but its appearance does not give away its affordable price tag. From its sleek silhouette to its long list of cabin features, this crossover SUV promises its passengers luxury, style and solid performance. The GLK250 Bluetec is the diesel variant of the standard GLK350, and has a 2.1-liter four-cylinder diesel engine that puts out 200 horsepower and 369 pound-feet of torque. The Bluetec, which hit showrooms in 2013, goes down in history as Mercedes-Benz's first diesel engine, rated at 38 mpg combined; a significant increase over the 21 mpg combined achieved by the gasoline-powered 350.
The Bluetec also gets Mercedes-Benz's signature 4Matic all-wheel-drive standard. On the downside, trunk space is limited, the back seat is a little tight, and handling is less agile than some competitors. On the upside, however, the Bluetec is luxurious, refined, and caters to a wider pool of buyers than other Mercedes-Benz models, thanks to its reasonable price.
