Safety Comparison

The Tahoe LTZ’s optional blind spot warning system uses rear-aimed sensors monitored by computer to alert the driver to moving objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. The GL Class doesn’t offer a system to reveal objects in the driver's blind spots.

Both the Tahoe and the GL Class have standard driver and passenger frontal airbags, front side-impact airbags, head airbags, front seatbelt pretensioners, height-adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding and available all-wheel drive.

Warranty Comparison

Chevrolet’s powertrain warranty covers the Tahoe 1 year and 50,000 miles longer than Mercedes covers the GL Class. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 100,000 miles. Coverage on the GL Class ends after only 4 years or 50,000 miles.

The Tahoe’s corrosion warranty is 2 years and 50,000 miles longer than the GL Class’ (6/100,000 vs. 4/50,000).

There are almost 14 times as many Chevrolet dealers as there are Mercedes dealers, which makes it much easier to get service under the Tahoe’s warranty.

Reliability Comparison

The Tahoe has a standard “limp home system” to keep drivers from being stranded if most or all of the engine’s coolant is lost. The engine will run on only half of its cylinders at a time, reduce its power and light a warning lamp on the dashboard so the driver can get to a service station for repairs. The GL Class doesn’t offer a lost coolant limp home mode, so a coolant leak could strand you or seriously damage the truck’s engine.

The Tahoe’s reliability is better than the GL Class’. In Consumer Reports, the Tahoe’s reliability is 50% better.

J.D. Power and Associates rated the Tahoe second among large multi-activity vehicles in their 2009 Initial Quality Study. The GL Class was rated third in its category.

Engine Comparison

The Tahoe Hybrid’s standard 6.0 V8 hybrid produces 28 lbs.-ft. more torque (367 vs. 339) than the GL450’s standard 4.7 DOHC V8.

Fuel Economy and Range Comparison

On the EPA test cycle the Tahoe 4x4 V8 gets better fuel mileage than the GL450 4.7 V8 (14 city/19 hwy vs. 13 city/17 hwy).

An engine control system that can shut down half of the engine’s cylinders helps improve the Tahoe’s fuel efficiency. The GL Class doesn’t offer a system that can shut down part of the engine.

To lower fuel costs and make buying fuel easier, the Chevrolet Tahoe uses regular unleaded gasoline. The GL Class requires premium, which can cost 25 to 50 cents more per gallon.

Tires and Wheels Comparison

For better ride, handling and brake cooling the Tahoe offers optional 22-inch wheels. The GL Class’ largest wheels are only 21 inches.

The Chevrolet Tahoe’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Mercedes GL Class only has 5 wheel lugs per wheel.

The Tahoe has a standard full size spare tire so your trip isn’t interrupted by a flat. A full size spare isn’t available on the GL Class, it requires you to depend on a temporary spare, which limits mileage and speed before replacement.

Suspension and Handling Comparison

For better handling and stability, the track (width between the wheels) on the Tahoe is 3.2 inches wider in the front and 1.9 inches wider in the rear than on the GL Class.

The Tahoe LTZ 4x4 handles at .72 G’s, while the GL450 pulls only .71 G’s of cornering force in a Car and Driver skidpad test.

The Tahoe LTZ 4x4 goes through Motor Trend’s slalom faster than the GL450 (57.2 vs. 57.1 MPH).

For better maneuverability, the Tahoe’s turning circle is .7 feet tighter than the GL Class’ (39 feet vs. 39.7 feet).

Chassis Comparison

To almost totally eliminate engine vibration in the passenger area, the Tahoe has liquid-filled engine mounts. The liquid helps further dampen engine harshness. The GL Class uses conventional solid rubber engine mounts.

The design of the Chevrolet Tahoe amounts to more than styling. The Tahoe offers aerodynamic coefficients of drag from .34 to .363 Cd (depending on bodystyle and options). That is lower than the GL Class (.37 to .4). A more efficient exterior helps keep the interior quieter and helps the Tahoe get better fuel mileage.

As tested by Car and Driver while at idle, the interior of the Tahoe Hybrid 4x4 is quieter than the GL450 (40 vs. 45 dB).

Passenger Space Comparison

The Tahoe has standard seating for 9 passengers; the GL Class can only carry 7.

The Tahoe has 1 inch more front headroom, 7 inches more front shoulder room, 6.3 inches more rear shoulder room and 11.2 inches more third row shoulder room than the GL Class.

Cargo Capacity Comparison

The Tahoe’s cargo area provides more volume than the GL Class.

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

Ergonomics Comparison

The Tahoe offers a remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The driver can also remotely turn on the heater or air conditioner. The GL Class doesn’t offer a remote starting system.

The Tahoe (except LS)’s optional easy entry system glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The GL Class doesn’t offer an easy entry system.

The Tahoe’s instruments include an oil pressure gauge and a temperature gauge – which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The GL Class has neither an oil pressure gauge nor a temperature gauge.

To improve rear visibility by keeping the rear window clear, the Tahoe has a standard rear fixed 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.

When the Tahoe with available tilt-down mirrors is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The GL Class’ mirrors don’t automatically adjust for backing.

Economic Advantages Comparison

Insurance will cost less for the Tahoe owner. The Complete Car Cost Guide estimates that insurance for the Tahoe will cost $1232 to $1504 less than the GL Class over a five-year period.
