For better handling and stability, the track (width between the wheels) on the Q5 is 3 inches wider in the front and 2.7 inches wider in the rear than on the GLK-Class.

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-Class (.34 to .36) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the Q5 get better fuel mileage.

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

The Q5 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-Class doesn’t offer air conditioned front seats.
