Compare the2023 Toyota PriusVS 2023 Mazda 3

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 Prius are reminded to check the back seat if they opened the rear door before starting out. The Mazda 3 doesn’t offer a back seat reminder.

The Prius has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Mazda 3 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.

The Prius 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 Mazda 3 Select/Preferred/Carbon/Premium/Turbo offers a blind spot warning system.

To help make backing out of a parking space safer, the Prius 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 Mazda 3 Select/Preferred/Carbon/Premium/Turbo has a rear cross-path warning system.

Both the Prius and the Mazda 3 have standard driver and passenger frontal airbags, front and rear side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, driver alert monitors and available around view monitors.

Toyota pays for scheduled maintenance on the Prius for 2 years and 25000 miles. Toyota will pay for oil changes, lubrication and any other required maintenance. Mazda doesn’t pay scheduled maintenance for the 3.

There are over 2 times as many Toyota dealers as there are Mazda dealers, which makes it much easier should you ever need service under the Prius’ warranty.

The battery on the Prius is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the Prius’ battery 20 to 30 degrees cooler, its life is increased by years. The Mazda 3’s battery is in the hot engine compartment.

J.D. Power and Associates’ 2022 Initial Quality Study of new car owners surveyed provide the statistics that show that Toyota vehicles are better in initial quality than Mazda vehicles. J.D. Power ranks Toyota above average in initial quality. With 8 more problems per 100 vehicles, Mazda is rated lower.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Toyota vehicles are more reliable than Mazda vehicles. J.D. Power ranks Toyota above average in long-term dependability. With 34 more problems per 100 vehicles in the first three years of ownership, Mazda is rated lower.

The Prius’ standard 2.0 DOHC 4-cylinder hybrid produces 3 more horsepower (194 vs. 191) than the Mazda 3’s standard 2.5 DOHC 4-cylinder.

As tested in Car and Driver the Toyota Prius 2.0 is faster than the Mazda 3 4 cyl. (automatics tested):

On the EPA test cycle the Prius gets better mileage than the Mazda 3 Sedan:

On the EPA test cycle the Prius gets better mileage than the Mazda 3 Hatchback:

Regenerative brakes improve the Prius’ fuel efficiency by converting inertia back into energy instead of wasting it. The Mazda 3 doesn’t offer a regenerative braking system.

To lower fuel costs and make buying fuel easier, the Toyota Prius uses regular unleaded gasoline. The Mazda 3 with the 2.5 turbo 4-cylinder engine requires premium for maximum efficiency, which can cost 20 to 55 cents more per gallon.

The Prius has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The Mazda 3 doesn’t offer a CVT.

For better stopping power the Prius AWD-e’s brake rotors are larger than those on the Mazda 3:

The Prius stops shorter than the Mazda 3:

For better ride, handling and brake cooling the Prius LE has standard 17-inch wheels. Smaller 16-inch wheels are standard on the Mazda 3 2.5 S. The Prius XLE/Limited’s 19-inch wheels are larger than the 18-inch wheels on the Mazda 3 Hatchback/Select/Preferred/Premium/Turbo.

For superior ride and handling, the Toyota Prius 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 3 has a rear torsion beam axle, with a semi-independent rear suspension.

The Prius has standard front and rear stabilizer bars, which help keep the Prius flat and controlled during cornering. The Mazda 3’s suspension doesn’t offer a rear stabilizer bar.

The Prius Limited handles at .87 G’s, while the Mazda 3 Premium Sedan AWD pulls only .83 G’s of cornering force in a Car and Driver skidpad test.

The front grille of the Prius uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Mazda 3 doesn’t offer active grille shutters.

Because it has more passenger and cargo room, the EPA rates the Prius a Mid-size car, while the Mazda 3 is rated a Compact.

The Prius has .9 inches more front legroom, .1 inches more front hip room and .8 inches more rear hip room than the Mazda 3 Sedan.

The Prius has a much larger trunk than the Mazda 3 Sedan (23.8 vs. 13.2 cubic feet).

To allow full utilization of available cargo room, the Prius’ hatch uses gas strut supported hinges that don’t intrude into the cargo area. The Mazda 3’s useful trunk space is reduced by its intrusive beam hinge (except wagon).

The Prius Limited’s standard easy entry system glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The Mazda 3 doesn’t offer an easy entry system.

The power windows standard on both the Prius and the Mazda 3 have locks to prevent small children from operating them. When the lock on the Prius is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Mazda 3 prevents the driver from operating the other windows just as it does the other passengers.

If the windows are left open on the Prius the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. The driver of the Mazda 3 can only close the windows from inside the vehicle, with the ignition on.

The Prius’ standard outside mirrors include heating elements to clear off the mirrors for better visibility. Mazda only offers heated mirrors on the Mazda 3 Carbon/Turbo.

Both the Prius and the Mazda 3 offer available heated front seats. The Prius Limited also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Mazda 3.

Standard air-conditioned seats in the Prius Limited keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Mazda 3 doesn’t offer air-conditioned seats.

The Prius’ optional Advanced Park can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The Mazda 3 doesn’t offer an automated parking system.

The Toyota Prius outsold the Mazda 3 by 29% during the 2022 model year.
