Compare the2025 Audi Q3VS 2025 Mazda CX-50

The Q3’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The CX-50 doesn’t offer pre-crash pretensioners.

Both the Q3 and CX-50 have child safety locks to prevent children from opening the rear doors. The Q3 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 CX-50’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.

When descending a steep, off-road slope, the Q3’s standard Hill Descent Control allows you to creep down safely. The CX-50 doesn’t offer Hill Descent Control.

To help make backing out of a parking space safer, the Q3 has standard Rear Cross-Traffic Assist with Automatic Brake Activation, systems which detect vehicles approaching from the sides and can automatically apply the brakes to prevent a collision. Only the CX-50 Turbo Premium Plus offers Rear Cross Traffic Braking.

Both the Q3 and the CX-50 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.

The Q3 comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The CX-50’s 3-year/36,000-mile basic warranty expires 1 year or 14,000 miles sooner.

The Q3’s corrosion warranty is 7 years longer than the CX-50’s (12 vs. 5 years).

The Audi Q3’s engines use a cast iron block for durability, while the CX-50’s engines use an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

To reliably power the ignition and other systems and to recharge the battery, the Q3 has a 140-amp alternator. The CX-50’s standard 100-amp alternator isn’t as powerful.

J.D. Power and Associates rated the Q3 second among small premium suvs in their 2024 Initial Quality Study. The CX-50 isn’t in the top three in its category.

The Q3 has more powerful engines than the CX-50:

As tested in Consumer Reports the Q3 45 TFSI is faster than the Mazda CX-50 4 cyl.:

Regardless of its engine, the Q3’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. Mazda only offers an automatic engine start/stop system on the CX-50 Turbo/Hybrid.

The Q3 has 1.4 gallons more fuel capacity than the CX-50 Hybrid’s standard fuel tank (15.9 vs. 14.5 gallons), for longer range between fill-ups.

An eight-speed automatic is standard on the Audi Q3, for better acceleration and lower engine speed on the highway. Only a six-speed automatic is available for the CX-50.

For better stopping power the Q3’s front brake rotors are larger than those on the CX-50:

The Q3’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the CX-50 are solid, not vented.

The Q3 stops much shorter than the CX-50:

For better traction, the Q3 has larger standard tires than the CX-50 (235/55R18 vs. 225/65R17). The Q3’s optional tires are larger than the largest tires available on the CX-50 (255/45R19 vs. 245/45R20).

The Q3’s standard tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the CX-50’s standard 65 series tires. The Q3’s optional tires have a lower 40 series profile than the CX-50 Premium Plus/Turbo’s 45 series tires.

For better ride, handling and brake cooling the Q3 has standard 18-inch wheels. Smaller 17-inch wheels are standard on the CX-50.

For superior ride and handling, the Audi Q3 has fully independent front and rear suspensions. An independent suspension allows the wheels to follow the road at the best angle for gripping the pavement, without compromising ride comfort. The Mazda CX-50 has a rear torsion beam axle, with a semi-independent rear suspension.

The Q3 has standard front and rear stabilizer bars, which help keep the Q3 flat and controlled during cornering. The CX-50’s suspension doesn’t offer a rear stabilizer bar.

The Q3 handles at .91 G’s, while the CX-50 2.5 Turbo Premium pulls only .84 G’s of cornering force in a Car and Driver skidpad test.

The Q3 is 9.2 inches shorter than the CX-50, making the Q3 easier to handle, maneuver and park in tight spaces.

The Q3 has .5 inches more front headroom, .8 inches more front shoulder room and 1.5 inches more rear shoulder room than the CX-50.

For enhanced passenger comfort on long trips the Q3’s rear seats recline. The CX-50’s rear seats don’t recline.

A standard locking glovebox keeps your small valuables safer in the Q3. The CX-50 doesn’t offer locking storage for small valuables.

To make loading groceries and cargo easier when your hands are full, the Q3’s available liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The CX-50 doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

The power windows standard on both the Q3 and the CX-50 have locks to prevent small children from operating them. When the lock on the Q3 is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The CX-50 prevents the driver from operating the other windows just as it does the other passengers.

If the windows are left open on the Q3 the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the CX-50 can only close the windows from inside the vehicle, with the ignition on.

Heated windshield washer nozzles are standard on the Q3 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The CX-50 doesn’t offer heated windshield washer nozzles.

The Q3’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Mazda only offers heated mirrors on the CX-50 Preferred/Premium/Turbo.

The Q3 will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the Q3 will retain 56.3% to 56.96% of its original price after five years, while the CX-50 only retains 53.88% to 56.04%.
