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.

The Q3 has a standard blind spot warning system which uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. Only the CX-30 Select/Preferred/Carbon/Premium offers a blind spot warning system.

To help make backing out of a parking space safer, the Q3 has a standard rear cross-path warning system, which uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. Only the CX-30 Select/Preferred/Carbon/Premium has a rear cross-path warning system.

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, rearview cameras 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:

	Q3	CX-30
	Front Seat
STARS	5 Stars	5 Stars
Chest Movement	.7 inches	1 inches
Abdominal Force	95 lbs.	209 lbs.
	Rear Seat
STARS	5 Stars	5 Stars
HIC	159	197
Spine Acceleration	43 G’s	60 G’s
	Into Pole
STARS	5 Stars	5 Stars
Hip Force	485 lbs.	583 lbs.

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

Warranty

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).

Reliability

The Audi Q3’s engine uses 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.

Engine

The Q3’s 2.0 turbo 4-cylinder produces 37 more horsepower (228 vs. 191) and 72 lbs.-ft. more torque (258 vs. 186) than the CX-30’s standard 2.5 DOHC 4-cylinder.

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

	Q3	CX-30
Zero to 60 MPH	7.8 sec	8.7 sec
45 to 65 MPH Passing	4.9 sec	5.2 sec
Quarter Mile	16.1 sec	16.7 sec
Speed in 1/4 Mile	91 MPH	88 MPH

Fuel Economy and Range

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.

The Q3 has 3.2 gallons more fuel capacity than the CX-30 (15.9 vs. 12.7 gallons), for longer range between fill-ups.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Audi Q3 higher (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.

Transmission

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.

Brakes and Stopping

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

	Q3	CX-30
Front Rotors	13.4 inches	11.6 inches
Rear Rotors	11.8 inches	10.4 inches
Opt Rear Rotors	12.2 inches	11.9 inches

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:

	Q3	CX-30
70 to 0 MPH	160 feet	177 feet	Car and Driver
60 to 0 MPH	126 feet	133 feet	Consumer Reports
60 to 0 MPH (Wet)	135 feet	147 feet	Consumer Reports

Tires and Wheels

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/Turbo/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/Turbo/Premium.

Suspension and Handling

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.

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).

The Q3 handles at .91 G’s, while the CX-30 Premium pulls only .84 G’s of cornering force in a Car and Driver skidpad test.

Passenger Space

The Q3 has 1.5 inches more front headroom, 1.1 inches more front shoulder room and 1.5 inches more rear shoulder room than the CX-30.

For enhanced passenger comfort on long trips the Q3’s rear seats recline. The CX-30’s rear seats don’t recline.

Cargo Capacity

The Q3 has a much larger cargo volume with its rear seat up than the CX-30 with its rear seat up (23.7 vs. 20.2 cubic feet). The Q3 has a much larger cargo volume with its rear seat folded than the CX-30 with its rear seat folded (48 vs. 45.2 cubic feet).

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.

Towing

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

Servicing Ease

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.

Ergonomics

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.

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 Carbon/Turbo.

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.
