Safety Comparison

To provide maximum traction and stability on all roads, All Wheel Drive is standard on the Q5. But it costs extra on the GLK.

When descending a steep, off-road slope, the Q5’s standard Audi Hill Descent Control allows you to creep down safely. The GLK doesn’t offer Audi Hill Descent Control.

The Q5 3.2 Prestige’s blind spot warning system uses digital cameras 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 GLK doesn’t offer a system to reveal objects in the driver's blind spots.

Both the Q5 and the GLK have standard driver and passenger frontal airbags, front side-impact airbags, head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, plastic fuel tanks, four wheel antilock brakes, traction control and electronic stability systems to prevent skidding.

For its top level performance in frontal, side, rear impact and roof-crush tests, and its standard Electronic Stability Program, the Insurance Institute for Highway Safety rates the Q5 as a “Top Pick” for 2010, a rating only granted to 55 vehicles tested by the IIHS. The GLK was not a “Top Pick.”

Warranty Comparison

The Q5’s corrosion warranty is 8 years and unlimited miles longer than the GLK’s (12/unlimited vs. 4/50,000).

Audi pays for scheduled maintenance on the Q5 for 1 year and 5000 miles. Audi will pay for oil changes, tire rotation, lubrication and any other scheduled maintenance. Mercedes doesn’t pay scheduled maintenance for the GLK.

Tires and Wheels Comparison

For better traction, the Q5’s optional tires are larger than the largest tires available on the GLK (255/45R20 vs. 235/50R19).

Suspension and Handling Comparison

For a smoother ride and more stable handling, the Q5’s wheelbase is 2 inches longer than on the GLK (110.5 inches vs. 108.5 inches).

For better handling and stability, the track (width between the wheels) on the Q5 is 3.6 inches wider in the front and 1 inch wider in the rear than on the GLK.

The Q5 handles at .83 G’s, while the GLK350 4Matic pulls only .78 G’s of cornering force in a Car and Driver skidpad test.

The Q5 executes Motor Trend’s “Figure Eight” maneuver 1.3 seconds quicker than the GLK350 4Matic (26.9 seconds @ .65 average G’s vs. 28.2 seconds @ .59 average G’s).

Chassis Comparison

The design of the Audi Q5 amounts to more than styling. The Q5 has an aerodynamic coefficient of drag of .33 Cd. That is lower than the GLK (.35) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the Q5 get better fuel mileage.

Passenger Space Comparison

The Q5 has .4 inches more front headroom, 2.5 inches more front shoulder room, 2.3 inches more rear legroom and 1 inch more rear shoulder room than the GLK.

For enhanced passenger comfort on long trips the Q5’s rear seats recline. The GLK’s rear seats don’t recline.

Cargo Capacity Comparison

The Q5 has a much larger cargo area with its rear seat up than the GLK with its rear seat up (29.1 vs. 23.3 cubic feet). The Q5 has a much larger cargo area with its rear seat folded than the GLK with its rear seat folded (57.3 vs. 54.7 cubic feet).

The Q5’s cargo area is larger than the GLK’s in every dimension:



Length to seat (2nd/1st)



Min Width



Ergonomics Comparison

The Q5’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The GLK’s standard manually variable intermittent wipers have to be constantly adjusted.

Heated windshield washer nozzles are standard on the Q5 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The GLK doesn’t offer heated windshield washer nozzles.

Consumer Reports rated the Q5’s headlight performance “Good,” a higher rating than the GLK’s headlights, which were rated “Poor.”

The GLK’s optional cornering lamps activate a lamp on the front corner when the turn signal is activated. The Q5 3.2 Prestige’s standard adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.

The Q5 3.2 Prestige’s optional air conditioned front seats cool the driver and front passenger and help take the sting out of hot leather in Summer. The GLK doesn’t offer air conditioned front seats.

To keep a safe, consistent following distance, the Q5 3.2 Prestige offers an optional Audi Adaptive Cruise Control, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The GLK doesn’t offer an adaptive cruise control.

Economic Advantages Comparison

Insurance will cost less for the Q5 owner. The Car Book by Jack Gillis rates the Q5 with a number “3” insurance rate while the GLK is rated higher at a number “5” rate.
