The Mirai 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 MX-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.

Both the Mirai and the MX-30 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, 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, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.

The Toyota Mirai weighs 600 to 680 pounds more than the Mazda MX-30. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

Warranty

Toyota pays for scheduled maintenance on the Mirai for 3 years and 35000 miles. Toyota will pay for tire rotations, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Mazda doesn’t pay scheduled maintenance for the MX-30.

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 Mirai’s warranty.

Reliability

J.D. Power and Associates’ 2023 Initial Quality Study of new car owners surveyed provide the statistics that show that Toyota vehicles are better in initial quality than Mazda vehicles. With 9 fewer problems per 100 vehicles, JD Power ranks Toyota higher than Mazda.

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.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Toyota vehicles are more reliable than Mazda vehicles. Consumer Reports ranks Toyota second in overall reliability. Mazda is ranked 7th.

Engine

The Mirai’s electric motor produces 39 more horsepower (182 vs. 143) and 21 lbs.-ft. more torque (221 vs. 200) than the MX-30’s electric motor.

Fuel Economy and Range

The Mirai can travel longer on a full tank of hydrogen than the MX-30 on a full charge:

		Miles
Mirai
	XLE Electric Motor	402 miles
	Limited Electric Motor	357 miles
MX-30
	Electric Motor	100 miles

Brakes and Stopping

The Mirai’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the MX-30 are solid, not vented.

Tires and Wheels

For better traction, the Mirai has larger standard tires than the MX-30 (235/55R19 vs. 215/55R18). The Mirai Limited’s optional tires are larger than the largest tires available on the MX-30 (245/45R20 vs. 215/55R18).

The Mirai Limited’s optional tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the MX-30’s 55 series tires.

For better ride, handling and brake cooling the Mirai has standard 19-inch wheels. Only 18-inch wheels are available on the MX-30. The Mirai Limited offers optional 20-inch wheels.

Suspension and Handling

For superior ride and handling, the Toyota Mirai 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 MX-30 has a rear torsion beam axle, with a semi-independent rear suspension.

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

For a smoother ride and more stable handling, the Mirai’s wheelbase is 10.5 inches longer than on the MX-30 (114.9 inches vs. 104.4 inches).

For better handling and stability, the track (width between the wheels) on the Mirai is 1.8 inches wider in the front and 1.6 inches wider in the rear than on the MX-30.

Passenger Space

The Mirai has .6 inches more front legroom, 1.8 inches more front hip room, 2.8 inches more front shoulder room, 3 inches more rear legroom, 4.3 inches more rear hip room and 1.7 inches more rear shoulder room than the MX-30.

Cargo Capacity

With its sedan body style, valet key and remote trunk release lockout, the Mirai offers cargo security. The MX-30’s sport utility bodystyle defeats cargo security.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the Mirai. The MX-30 doesn’t offer locking storage for small valuables.

Servicing Ease

The Mirai uses gas struts to support the hood for easier service access. The MX-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.

Ergonomics

Unlike the driver-only memory seat and mirrors in the MX-30, the Mirai Limited has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position (with optional power wheel adjuster) and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The power windows standard on both the Mirai and the MX-30 have locks to prevent small children from operating them. When the lock on the Mirai is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The MX-30 prevents the driver from operating the other windows just as it does the other passengers.

If the windows are left open on the Mirai 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. (This window function must be activated by your Toyota service department.) The driver of the MX-30 can only operate the windows from inside the vehicle, with the ignition on.

A power rear sunshade and manual rear side window sunshades are standard in the Mirai Limited to help block heat and glare for the rear passengers. The MX-30 doesn’t offer a rear or rear side window sunshades.

Both the Mirai and the MX-30 have standard heated front seats. The Mirai Limited also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the MX-30.

Standard air conditioned seats in the front and rear seats keep the Mirai Limited’s passengers comfortable and take the sting out of hot leather in summer. The MX-30 doesn’t offer air-conditioned seats.

The Mirai’s 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. The MX-30 doesn’t offer dual zone air conditioning.

Both the Mirai and the MX-30 offer rear vents. For greater rear passenger comfort, the Mirai has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The MX-30 doesn’t offer rear air conditioning vents, only heat vents.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Toyota Mirai has a standard wireless phone charging system (Qi) in the center console. The MX-30 doesn’t offer wireless personal charging.

The Mirai Limited’s Intelligent Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The MX-30 doesn’t offer an automated parking system.

Recommendations

The Toyota Mirai outsold the Mazda MX-30 by over 27 to one during 2023.
