Safety Comparison

Both the X5 and the GL-Class have standard driver and passenger frontal airbags, side-impact head airbags, front seatbelt pretensioners, traction control, electronic stability systems to prevent skidding and available all wheel drive.

Warranty Comparison

The X5’s corrosion warranty is 8 years and unlimited miles longer than the GL-Class’ (12/unlimited vs. 4/50,000).

BMW pays for scheduled maintenance on the X5 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 GL-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 X5’s warranty.

Engine Comparison

The X5’s 3.0 turbo diesel produces 15 more horsepower (255 vs. 240) than the GL-Class’ 3.0 turbo V6 diesel.

Fuel Economy and Range Comparison

On the EPA test cycle the X5 xDrive35d gets better fuel mileage than the GL350 BlueTEC (23 city/31 hwy vs. 19 city/26 hwy).

Regenerative brakes improve the X5’s fuel efficiency by converting inertia back into energy instead of wasting it. The GL-Class doesn’t offer a regenerative braking system.

Regardless of its engine, the X5’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) Mercedes only offers an automatic engine start/stop system on the GL-Class GL63 AMG.

Tires and Wheels Comparison

The X5’s optional 315/35R20 rear tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the GL550/GL63 AMG’s 40 series tires.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the X5 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The GL-Class doesn’t offer run-flat tires.

Suspension and Handling Comparison

The X5 offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Mercedes doesn’t offer an active suspension on the GL-Class.

Chassis Comparison

The BMW X5 may be more efficient, handle and accelerate better because it weighs about 450 to 700 pounds less than the Mercedes GL-Class.

The X5 is 8.4 inches shorter than the GL-Class GL350 BlueTEC/GL450, making the X5 easier to handle, maneuver and park in tight spaces.

The design of the BMW X5 amounts to more than styling. The X5 has an aerodynamic coefficient of drag of .33 Cd. That is significantly lower than the GL-Class (.369 to .377) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the X5 get better fuel mileage.

Passenger Space Comparison

The X5 has .1 inches more front legroom and 2 inches more front shoulder room than the GL-Class.

Cargo Capacity Comparison

The X5’s rear cargo window opens separately from the rest of the tailgate door to allow quicker loading of small packages. The GL-Class’ rear cargo window doesn’t open.

Ergonomics Comparison

The X5’s standard easy entry system raises the steering wheel, making it easier for the driver to get in and out. An easy entry system costs extra on the GL-Class.

The X5 offers an optional heads-up display which projects speed and other key instrumentation readouts onto the windshield, allowing drivers to view information without diverting their eyes from the road. The GL-Class doesn’t offer a heads-up display.

Heated windshield washer nozzles are standard on the X5 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The GL-Class doesn’t offer heated windshield washer nozzles.

To improve rear visibility by keeping the rear window clear, the X5 has a standard rear variable intermittent wiper with a full on position. The rear wiper standard on the GL-Class only has an intermittent setting, so in a hard rain visibility isn’t as good.

Economic Advantages Comparison

Insurance will cost less for the X5 owner. The Complete Car Cost Guide estimates that insurance for the X5 will cost $455 less than the GL-Class over a five-year period.

The X5 will cost the buyer less in the long run because of its superior resale value. The Intellichoice estimates that the X5 will retain 49.67% to 53.21% of its original price after five years, while the GL-Class only retains 42.57% to 48.29%.

Intellichoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the BMW X5 will be $11233 to $50769 less than for the Mercedes GL-Class.

Recommendations Comparison

The BMW X5 outsold the Mercedes GL-Class by 33% during 2013.
