For enhanced safety, the front and rear seat shoulder belts of the Toyota Mirai have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Chevrolet Bolt doesn’t offer pretensioners for its rear seat belts.

For enhanced safety, the front seat shoulder belts of the Toyota Mirai are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Chevrolet Bolt doesn’t offer height-adjustable seat belts.

The Mirai has standard Whiplash Injury Lessening Seats (WIL), which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the WIL system moves the headrests forward to prevent neck and spine injuries. The Bolt doesn’t offer a whiplash protection system.

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 Bolt 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.

Over 200 people are killed each year when backed over by motor vehicles. The Mirai offers an optional Parking Support Brake that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Bolt doesn’t offer backup collision prevention brakes.

The Mirai has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the Bolt’s blind spot costs extra.

To help make backing out of a parking space safer, the Mirai has standard Rear Cross Traffic Alert to warn the driver of approaching traffic and automatically engage the brakes to help avoid a collision. Chevrolet charges extra for Rear Cross Traffic Alert on the Bolt and the Bolt’s Rear Cross Traffic Alert does not include automatic braking.

The Mirai’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 Bolt doesn’t offer a driver alert monitor.

Both the Mirai and the Bolt have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, four-wheel antilock brakes, 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 Toyota Mirai weighs 631 to 738 pounds more than the Chevrolet Bolt. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

Warranty

The Mirai’s corrosion warranty is unlimited miles longer than the Bolt’s (unlimited vs. 100,000 miles).

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. Chevrolet only pays for the first scheduled maintenance visit on the Bolt.

Reliability

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 Chevrolet 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, Chevrolet is rated lower.

From surveys of all its subscribers, Consumer Reports’ January 2023 Auto Issue reports that Toyota vehicles are more reliable than Chevrolet vehicles. Consumer Reports ranks Toyota first in overall reliability. Chevrolet is ranked 20th.

Engine

The Mirai’s electric motor produces 34 lbs.-ft. more torque (300 vs. 266) than the Bolt’s electric motor.

Fuel Economy and Range

The Mirai can travel longer on a full tank of hydrogen than the Bolt on a full charge:

		Miles
Mirai
	XLE Electric Motor	402 miles
	Limited Electric Motor	357 miles
Bolt
	Electric Motor	259 miles

The Mirai has a standard locking fuel door with a power remote release convenient to the driver. The Bolt doesn’t have a locking charge port. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank and a locking charge port prevents tampering and damage.

Brakes and Stopping

For better stopping power the Mirai’s brake rotors are larger than those on the Bolt:

	Mirai	Bolt
Front Rotors	11.6 inches	10.9 inches
Rear Rotors	11.4 inches	10.4 inches

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 Bolt are solid, not vented.

The Mirai stops much shorter than the Bolt:

	Mirai	Bolt
60 to 0 MPH	116 feet	132 feet	Motor Trend

Tires and Wheels

For better traction, the Mirai has larger standard tires than the Bolt (235/55R19 vs. 215/50R17). The Mirai Limited’s optional tires are larger than the largest tires available on the Bolt (245/45R20 vs. 215/50R17).

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 Bolt’s 50 series tires.

For better ride, handling and brake cooling the Mirai has standard 19-inch wheels. Only 17-inch wheels are available on the Bolt. 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 Chevrolet Bolt has a rear torsion beam axle, with a semi-independent rear suspension.

The Mirai has standard front and rear gas-charged shocks for better control over choppy roads. The Bolt’s suspension doesn’t offer gas-charged shocks.

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

For a smoother ride and more stable handling, the Mirai’s wheelbase is 12.5 inches longer than on the Bolt (114.9 inches vs. 102.4 inches).

For better handling and stability, the track (width between the wheels) on the Mirai is 4.2 inches wider in the front and 4 inches wider in the rear than on the Bolt.

The Mirai’s front to rear weight distribution is more even (50% to 50%) than the Bolt’s (55.9% to 44.1%). This gives the Mirai more stable handling and braking.

The Mirai XLE handles at .84 G’s, while the Bolt pulls only .75 G’s of cornering force in a Motor Trend skidpad test.

Chassis

The design of the Toyota Mirai amounts to more than styling. The Mirai has an aerodynamic coefficient of drag of .29 Cd. That is lower than the Bolt (.31) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the Mirai get better fuel mileage.

Passenger Space

The Mirai has 5.2 inches more front hip room, 3.7 inches more front shoulder room, 2.2 inches more rear hip room and 1.6 inches more rear shoulder room than the Bolt.

Cargo Capacity

With its sedan body style, valet key and remote trunk release lockout, the Mirai offers cargo security. The Bolt’s hatchback body style, non-lockable folding seat and non-lockable remote release defeat cargo security.

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

Servicing Ease

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

When two different drivers share the Mirai Limited, the memory system makes it convenient for both. Each setting activates different, customized memories for the driver’s seat position, steering wheel position (with optional power wheel adjuster) and outside mirror angle. The Bolt doesn’t offer a memory system.

The Mirai Limited’s standard easy entry system raises the steering wheel and 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 Bolt doesn’t offer an easy entry system.

The Mirai Limited has a standard heads-up display that projects speed 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 Bolt doesn’t offer a heads-up display.

The Mirai’s front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Bolt’s passenger windows don’t close automatically.

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 Bolt can only operate the windows from inside the vehicle, with the ignition on.

The Mirai Limited’s standard wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield. The Bolt’s manually variable intermittent wipers have to be constantly adjusted.

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 Bolt doesn’t offer a rear or rear side window sunshades.

When the Mirai Limited 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 Bolt’s mirrors don’t automatically adjust for backing.

The Mirai has standard heated front seats. Heated front seats cost extra on the Bolt. 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 Bolt.

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 Bolt 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 Bolt doesn’t offer dual zone air conditioning.

Both the Mirai and the Bolt 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 Bolt 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. Wireless charging costs extra on the Bolt.

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 Bolt doesn’t offer an automated parking system.
