Safety Comparison

When descending a steep, off-road slope, the X1 xDrive’s standard Hill Descent Control allows you to creep down safely. The GLK-Class doesn’t offer Hill Descent Control.

Both the X1 and the GLK-Class have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding and available all-wheel drive.

Warranty Comparison

The X1’s corrosion warranty is 8 years and unlimited miles longer than the GLK-Class’ (12/unlimited vs. 4/50,000).

BMW pays for scheduled maintenance on the X1 for 4 years and 50,000 miles. BMW will pay for oil changes, lubrication and any other required maintenance. Mercedes doesn’t pay scheduled maintenance for the GLK-Class.

There are over 12 percent more BMW dealers than there are Mercedes dealers, which makes it easier should you ever need service under the X1’s warranty.

Reliability Comparison

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without their vehicle while it’s being repaired. Consumer Reports predicts that the X1’s reliability will be 22% better than the GLK-Class.

J.D. Power and Associates’ 2014 Initial Quality Study of new car owners surveyed provide the statistics that show that BMW vehicles are better in initial quality than Mercedes vehicles. J.D. Power ranks BMW 8th in initial quality, above the industry average. With 7 more problems per 100 vehicles, Mercedes is ranked 13th.

The X1 has a gallon more fuel capacity than the GLK-Class Diesel’s standard fuel tank (16.6 vs. 15.6 gallons), for longer range between fill-ups.

Rear Rotors

Tires and Wheels Comparison

The X1’s optional 225/35R19 front and 255/30R19 rear tires provide better handling because they have a lower 35 series front and 30 series rear profile (height to width ratio) that provides a stiffer sidewall than the GLK-Class’ optional 45 series tires.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the X1 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. Run-flat tires aren’t available on some tire packages on the GLK-Class.

Suspension and Handling Comparison

The X1 xDrive28i xDrive handles at .81 G’s, while the GLK350 4MATIC pulls only .76 G’s of cornering force in a Motor Trend skidpad test.

The X1 xDrive35i xDrive executes Motor Trend’s “Figure Eight” maneuver 1.8 seconds quicker than the GLK350 4MATIC (26.7 seconds @ .69 average G’s vs. 28.5 seconds @ .55 average G’s).

For better maneuverability, the X1’s turning circle is 1.1 feet tighter than the GLK-Class’ (37.1 feet vs. 38.2 feet).

Chassis Comparison

The BMW X1 may be more efficient, handle and accelerate better because it weighs about 350 to 550 pounds less than the Mercedes GLK-Class.

For enhanced passenger comfort on long trips the X1’s rear seats recline. The GLK-Class’ rear seats don’t recline.
