The Q5’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The RDX doesn’t offer pre-crash pretensioners.

Both the Q5 and RDX have child safety locks to prevent children from opening the rear doors. The Q5 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The RDX’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

The Q5 has a standard Secondary Collision Brake Assist, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The RDX 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 RDX.

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

Warranty

The Q5’s corrosion warranty is 7 years longer than the RDX’s (12 vs. 5 years).

There are over 12 percent more Audi dealers than there are Acura dealers, which makes it easier should you ever need service under the Q5’s warranty.

Reliability

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

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Audi vehicles are more reliable than Acura With 12 fewer problems per 100 vehicles in the first three years of ownership, J.D. Power ranks Audi higher than Acura.

From surveys of all its subscribers, Consumer Reports’ January 2023 Auto Issue reports that Audi vehicles are more reliable than Acura vehicles. Consumer Reports ranks Audi 2 places higher in reliability than Acura.

Engine

The Q5 55 TFSI e’s standard 2.0 turbo 4-cylinder hybrid produces 90 more horsepower (362 vs. 272) and 89 lbs.-ft. more torque (369 vs. 280) than the RDX’s 2.0 turbo 4-cylinder.

As tested in Car and Driver the Q5 55 TFSI e is faster than the Acura RDX:

	Q5	RDX
Zero to 60 MPH	4.5 sec	6.2 sec
Zero to 100 MPH	12.2 sec	16.9 sec
5 to 60 MPH Rolling Start	4.9 sec	6.9 sec
Passing 30 to 50 MPH	3 sec	3.8 sec
Passing 50 to 70 MPH	3.9 sec	5.1 sec
Quarter Mile	13.2 sec	14.9 sec
Speed in 1/4 Mile	104 MPH	94 MPH
Top Speed	128 MPH	112 MPH

Fuel Economy and Range

On the EPA test cycle the Q5 running on electricity gets better mileage than the RDX:

		A-Spec 2.0 turbo 4-cyl.	22 city/27 hwy
	AWD	2.0 turbo 4-cyl.	21 city/27 hwy
		A-Spec 2.0 turbo 4-cyl.	21 city/26 hwy

The Q5 55 TFSI e can travel with zero emissions for 22 miles. The RDX can’t move without running its internal combustion engine.

Regenerative brakes improve the Q5’s fuel efficiency by converting inertia back into energy instead of wasting it. The RDX doesn’t offer a regenerative braking system.

The Q5’s standard fuel tank has 1.4 gallons more fuel capacity than the RDX (18.5 vs. 17.1 gallons).

Transmission

The Q5 offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The RDX doesn’t offer an SMG or a conventional manual transmission.

The Q5’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The RDX doesn’t offer launch control.

Brakes and Stopping

For better stopping power the Q5’s brake rotors are larger than those on the RDX:

	Q5 45 TFSI	Q5 55 TFSI e	RDX
Front Rotors	13.3 inches	13.8 inches	12.4 inches
Rear Rotors	13 inches	13 inches	12.2 inches

The Q5’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the RDX are solid, not vented.

The Q5 stops much shorter than the RDX:

	Q5	RDX
70 to 0 MPH	161 feet	180 feet	Car and Driver

Suspension and Handling

The Q5 55 TFSI e has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The Q5’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The RDX doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the Q5’s wheelbase is 2.7 inches longer than on the RDX (111 inches vs. 108.3 inches).

The Q5 45 TFSI Prestige executes Motor Trend’s “Figure Eight” maneuver quicker than the RDX AWD (27.2 seconds @ .65 average G’s vs. 27.7 seconds @ .62 average G’s).

Chassis

The Q5 is 3.1 inches shorter than the RDX, making the Q5 easier to handle, maneuver and park in tight spaces.

Passenger Space

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

Towing

The Q5’s standard towing capacity is much higher than the RDX’s (4400 vs. 1500 pounds).

Servicing Ease

The engine in the Q5 is mounted longitudinally (North-South), instead of sideways, as in the RDX. This makes it easier to service and maintain, because the accessory belts are in front.

Ergonomics

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 RDX’s standard 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 RDX doesn’t offer heated windshield washer nozzles.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The Q5 Prestige has standard headlight washers to keep headlight output high. The RDX doesn’t offer headlight washers.

The Q5 Prestige’s Park Steering Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The RDX doesn’t offer an automated parking system.

Economic Advantages

Insurance will cost less for the Q5 owner. The Car Book by Jack Gillis rates the Q5 with a number “5” insurance rate while the RDX is rated higher at a number “10” rate.

According to The Car Book by Jack Gillis, the Q5 is less expensive to operate than the RDX because typical repairs cost much less on the Q5 than the RDX, including $149 less for front brake pads and $736 less for a power steering pump.

Recommendations

Consumer Reports® recommends both the Audi Q5 and the Acura RDX, based on reliability, safety and performance.

The Audi Q5/SQ5 outsold the Acura RDX by almost three to one during 2022.
