The CX-30 has standard Whiplash-Reducing Headrests, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash-Reducing Headrests system moves the headrests forward to prevent neck and spine injuries. The Q3 doesn’t offer a whiplash protection system.

Over 200 people are killed each year when backed over by motor vehicles. The CX-30 Turbo Premium Plus has standard Rear Smart Brake Support that use rear sensors to monitor for objects to the rear and automatically apply the brakes to prevent a collision. The Q3 doesn’t offer automatic braking for stationary objects directly to the rear.

The CX-30’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Q3 doesn’t offer a driver alert monitor.

Both the CX-30 and the Q3 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, available blind spot warning systems, around view monitors and rear cross-path warning.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Mazda CX-30 is safer than the Audi Q3:

	CX-30	Q3
OVERALL STARS	5 Stars	4 Stars
	Driver
STARS	5 Stars	4 Stars
HIC	148	326
Neck Injury Risk	26.7%	39%
Neck Stress	216 lbs.	343 lbs.
Neck Compression	18 lbs.	35 lbs.
Leg Forces (l/r)	201/172 lbs.	235/363 lbs.
	Passenger
STARS	5 Stars	4 Stars
HIC	179	346
Chest Compression	.5 inches	.6 inches
Neck Injury Risk	33.5%	35%
Neck Stress	172 lbs.	186 lbs.

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

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 Mazda CX-30 is safer than the Audi Q3:

	CX-30	Q3
	Front Seat
STARS	5 Stars	5 Stars
HIC	73	88
Hip Force	275 lbs.	333 lbs.
	Rear Seat
STARS	5 Stars	5 Stars

	Into Pole
STARS	5 Stars	5 Stars
Max Damage Depth	12 inches	13 inches
HIC	178	504
Spine Acceleration	30 G’s	47 G’s

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

Side impacts caused 23% of all road fatalities in 2018, down from 29% in 2003, when the Insurance Institute for Highway Safety introduced its side barrier test. In order to continue improving vehicle safety, the IIHS has started using a more severe side impact test: 37 MPH (up from 31 MPH), with a 4180-pound barrier (up from 3300 pounds). The results of this newly developed test demonstrates that the Mazda CX-30 is safer than the Q3:

	CX-30	Q3
Overall Evaluation	GOOD	ACCEPTABLE
Structure	GOOD	ACCEPTABLE
	Driver Injury Measures
Head/Neck	GOOD	GOOD
Head Injury Criterion	89	190
Neck Tension	156 lbs.	335 lbs.

For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, and daytime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the CX-30 the rating of “Top Safety Pick” for 2023, a rating granted to only 53 vehicles tested by the IIHS. The Q3 last would have qualified as a “Top Safety Pick” in 2018.

Warranty

Mazda’s powertrain warranty covers the CX-30 1 year and 10,000 miles longer than Audi covers the Q3. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the Q3 ends after only 4 years or 50,000 miles.

There are over 78 percent more Mazda dealers than there are Audi dealers, which makes it much easier should you ever need service under the CX-30’s warranty.

Reliability

J.D. Power and Associates’ 2022 Initial Quality Study of new car owners surveyed provide the statistics that show that Mazda vehicles are better in initial quality than Audi vehicles. With 59 fewer problems per 100 vehicles, JD Power ranks Mazda higher than Audi.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Mazda vehicles are more reliable than Audi vehicles. J.D. Power ranks Mazda above average in long-term dependability. With 13 more problems per 100 vehicles in the first three years of ownership, Audi is rated below average.

From surveys of all its subscribers, Consumer Reports’ January 2023 Auto Issue reports that Mazda vehicles are more reliable than Audi vehicles. Consumer Reports ranks Mazda fourth in overall reliability. Audi is ranked 6th.

Engine

The CX-30’s optional 2.5 turbo 4-cylinder produces 22 more horsepower (250 vs. 228) and 62 lbs.-ft. more torque (320 vs. 258) than the Q3’s 2.0 turbo 4-cylinder.

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

	CX-30	Q3
Zero to 60 MPH	7.8 sec	8.5 sec
Quarter Mile	16 sec	16.5 sec
Speed in 1/4 Mile	88.3 MPH	85.4 MPH

Fuel Economy and Range

On the EPA test cycle the CX-30 gets better mileage than the Q3:

			MPG
CX-30
	AWD	2.5 turbo 4-cyl.	22 city/30 hwy
		2.5 DOHC 4-cyl.	26 city/33 hwy
Q3
	AWD	2.0 turbo 4-cyl.	21 city/28 hwy

An engine control system that can shut down some of the engine’s cylinders helps improve the CX-30 (except Turbo)’s fuel efficiency. The Q3 doesn’t offer a system that can shut down part of the engine.

Brakes and Stopping

The CX-30 stops shorter than the Q3:

	CX-30	Q3
60 to 0 MPH	119 feet	125 feet	Motor Trend

Suspension and Handling

The CX-30 Premium handles at .83 G’s, while the Q3 pulls only .79 G’s of cornering force in a Motor Trend skidpad test.

The CX-30 Premium executes Motor Trend’s “Figure Eight” maneuver 1 seconds quicker than the Q3 (27.4 seconds @ .62 average G’s vs. 28.4 seconds @ .65 average G’s).

For better maneuverability, the CX-30’s turning circle is 3.6 feet tighter than the Q3’s (34.8 feet vs. 38.4 feet).

Chassis

The Mazda CX-30 may be more efficient, handle and accelerate better because it weighs about 400 to 500 pounds less than the Audi Q3.

The CX-30 is 3.6 inches shorter than the Q3, making the CX-30 easier to handle, maneuver and park in tight spaces.

Passenger Space

The CX-30 has 10.1 cubic feet more passenger volume than the Q3 (94.1 vs. 84).

The CX-30 has 1.7 inches more front legroom, .7 inches more rear headroom and .2 inches more rear legroom than the Q3.

Ergonomics

The CX-30 Premium has a standard heads-up display that projects speed, warning and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Q3 doesn’t offer a heads-up display.

The CX-30’s power window, power lock and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Q3’s cruise control switches are unlit, making them difficult to find at night and operate safely.

Consumer Reports rated the CX-30’s headlight performance “Good,” a higher rating than the Q3’s headlights, which were rated “Fair.”

The Q3 Premium Plus’ cornering lamps activate a lamp on the front corner when the turn signal is activated. The CX-30 Premium’s standard adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.

When the CX-30 Preferred/Carbon/Premium is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The Q3’s mirrors don’t automatically adjust for backing.

On extremely cold winter days, the CX-30 Turbo’s standard heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the vehicle heater warms up. The Q3 doesn’t offer a heated steering wheel.

Recommendations

The Mazda CX-30 outsold the Audi Q3 by over two to one during 2022.
