Safety Comparison

The Q5 has standard Secondary Collision Brake Assist, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The MDX doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

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

Both the Q5 and the MDX have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

Warranty Comparison

Reliability Comparison

The Audi Q5’s engine uses a cast iron block for durability, while the MDX’s engines use an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

The camshafts in the Q5’s engine are driven by a hardened steel chain, with no maintenance needs. The MDX’s camshafts are driven by a rubber belt that needs periodic replacement. If the MDX’s cam drive belt breaks the engine could be severely damaged when the pistons hit the opened valves.

Consumer Reports

Tires and Wheels Comparison

For better traction, the Q5’s optional tires are larger than the largest tires available on the MDX (255/45R20 vs. 245/60R18).

The Q5’s optional tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the MDX’s optional 50 series tires.

Suspension and Handling Comparison

For greater off-road capability the Q5 has a greater minimum ground clearance than the MDX (8.2 vs. 7.3 inches), allowing the Q5 to travel over rougher terrain without being stopped or damaged.

Chassis Comparison

The Q5 is 1 foot shorter than the MDX, making the Q5 easier to handle, maneuver and park in tight spaces.

Passenger Space Comparison

The Q5 has 3.6 inches more front headroom, 1 inch more rear headroom and 1.2 inches more rear legroom than the MDX.

Cargo Capacity Comparison

Pressing a switch automatically lowers the Q5’s rear seats, to make changing between passengers and cargo easier. The MDX doesn’t offer automatic folding seats.

To make loading groceries and cargo easier when your hands are full, the Q5 Premium Plus/Prestige’s cargo door can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The MDX doesn’t offer a hands-free gesture to open its cargo door, forcing you to put cargo down if your hands are full.

Ergonomics Comparison

The power windows standard on both the Q5 and the MDX have locks to prevent small children from operating them. When the lock on the Q5 is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The MDX prevents the driver from operating the other windows just as it does the other passengers.

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 MDX’s intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

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 MDX doesn’t offer heated windshield washer nozzles.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Q5 has standard extendable sun visors. The MDX doesn’t offer extendable visors.
