Compare the2024 Audi Q3VS 2024 Mazda CX-30

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-30 doesn’t offer pre-crash pretensioners.

Both the Q3 and CX-30 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-30’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 Q3 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 CX-30 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.

When descending a steep, off-road slope, the Q3’s standard Hill Descent Control allows you to creep down safely. The CX-30 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-30 Turbo Premium Plus offers Smart Braking Support - Rear Crossing.

Both the Q3 and the CX-30 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, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the Audi Q3 is safer than the Mazda CX-30:

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

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-30’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-30’s (12 vs. 5 years).

The Audi Q3’s engines use a cast iron block for durability, while the CX-30’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-30’s standard 100-amp alternator isn’t as powerful.

J.D. Power and Associates rated the Q3 first among small premium suvs in their 2023 Initial Quality Study. The CX-30 isn’t in the top three in its category.

The Q3 40 TFSI’s standard 2.0 turbo 4-cylinder produces 35 lbs.-ft. more torque (221 vs. 186) than the CX-30’s standard 2.5 DOHC 4-cylinder.

As tested in Consumer Reports the Q3 45 TFSI is faster than the Mazda CX-30 4 cyl.:

In heavy traffic or at stoplights the Q3’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The CX-30 doesn’t offer an automatic engine start/stop system.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Audi Q3 higher (6 to 7 out of 10) than the Mazda CX-30 (5 to 7). This means the Q3 produces up to 8 pounds less smog-producing pollutants than the CX-30 every 15,000 miles.

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-30.

For better stopping power the Q3’s brake rotors are larger than those on the CX-30:

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-30 are solid, not vented.

The Q3 stops much shorter than the CX-30:

For better traction, the Q3 has larger standard tires than the CX-30 (235/55R18 vs. 215/65R16). The Q3’s optional tires are larger than the largest tires available on the CX-30 (255/45R19 vs. 215/65R16).

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-30 2.5 S’ standard 65 series tires. The Q3’s optional tires have a lower 40 series profile than the CX-30 Select/Preferred/Carbon/Premium’s 55 series tires.

For better ride, handling and brake cooling the Q3 has standard 18-inch wheels. Smaller 16-inch wheels are standard on the CX-30 2.5 S. The Q3’s optional 20-inch wheels are larger than the 18-inch wheels on the CX-30 Select/Preferred/Carbon/Premium.

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-30 has a rear torsion beam axle, with a semi-independent rear suspension.

The Q3 has standard front and rear gas-charged shocks for better control over choppy roads. The CX-30’s suspension doesn’t offer gas-charged shocks.

The Q3 has standard front and rear stabilizer bars, which help keep the Q3 flat and controlled during cornering. The CX-30’s suspension doesn’t offer a rear stabilizer bar.

For a smoother ride and more stable handling, the Q3’s wheelbase is 1.1 inches longer than on the CX-30 (105.5 inches vs. 104.4 inches).

A standard locking glovebox keeps your small valuables safer in the Q3. The CX-30 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-30 doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

The Q3 has a 1500 lbs. towing capacity. The CX-30 has no towing capacity.

The Q3 uses gas struts to support the hood for easier service access. The CX-30 uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

J.D. Power and Associates surveys of service recipients show that Audi service is better than Mazda. J.D. Power ranks Audi 8th in service department satisfaction (above the industry average). With a 9% lower rating, Mazda is ranked 11th.

The power windows standard on both the Q3 and the CX-30 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-30 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-30 can only operate 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-30 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-30 Select/Preferred/Carbon/Premium.

The Q3 has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning is only available on the CX-30 Select/Preferred/Carbon/Turbo/Premium.

Consumer Reports® recommends the Audi Q3, based on reliability, safety and performance. The Mazda CX-30 isn't recommended.
