In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the CX-30 are reminded to check the back seat if they opened the rear door before starting out. The Q3 doesn’t offer a back seat reminder.

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.

With its standard Smart Brake Support with Pedestrian Detection, the Mazda CX-30 is better at preventing collisions with pedestrians than the Audi Q3, according to the Insurance Institute for Highway Safety:

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, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.

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

The Mazda CX-30 has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2024 model year. This distinction is based on its exceptional performance in IIHS’ rigorous battery of safety tests. Specifically, it earned a “Good” rating in the latest, more stringent moderate overlap front crash test, a “Good” result in the updated side impact test, and a “Good” score in the revised pedestrian crash prevention test. The Q3 is not even a standard “Top Safety Pick” for 2024.

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 77 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

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the CX-30’s reliability 13 points higher than the Q3.

J.D. Power and Associates’ 2024 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 10 fewer problems per 100 vehicles, JD Power ranks Mazda higher than Audi.

J.D. Power and Associates’ 2024 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 5 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 2024 Auto Issue reports that Mazda vehicles are more reliable than Audi vehicles. Consumer Reports ranks Mazda 12 places higher in reliability than Audi.

Engine

The CX-30’s standard 2.5 DOHC 4-cylinder produces 7 more horsepower (191 vs. 184) than the Q3 40 TFSI’s standard 2.0 turbo 4-cylinder. The CX-30’s optional 2.5 turbo 4-cylinder produces 22 more horsepower (250 vs. 228) and 69 lbs.-ft. more torque (320 vs. 251) than the Q3 45 TFSI’s standard 2.0 turbo 4-cylinder.

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

	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	40 TFSI 2.0 turbo 4-cyl.	22 city/29 hwy
		45 TFSI 2.0 turbo 4-cyl.	20 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 2.5 S 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 2.5 S 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 3.9 feet tighter than the Q3’s (34.8 feet vs. 38.7 feet).

For greater off-road capability the CX-30 has a 2.5 inches greater minimum ground clearance than the Q3 (8 vs. 5.5 inches), allowing the CX-30 to travel over rougher terrain without being stopped or damaged.

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 has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The Q3 doesn’t offer a remote starting system.

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 has a standard Pushbutton Start that allows you to start the engine without removing the key from the pocket or purse. The Audi Advanced Key costs extra on the Q3.

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 Premium’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.

Economic Advantages

Insurance will cost less for the CX-30 owner. The Complete Car Cost Guide estimates that insurance for the CX-30 will cost $95 to $1660 less than the Q3 over a five-year period.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Mazda CX-30 will be $4573 to $10743 less than for the Audi Q3.

Recommendations

Consumer Reports® recommends both the Mazda CX-30 and the Audi Q3, based on reliability, safety and performance.

The Mazda CX-30 outsold the Audi Q3 by over three to one during 2023.
