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

Both the Niro EV and the Mirai have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front 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, blind spot warning systems, rearview cameras, rear cross-path warning and available front and rear parking sensors.


The Niro EV comes with a full 5-year/60,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Mirai’s 3-year/36,000-mile basic warranty expires 2 years and 24,000 miles sooner.

Car and Driver

Suspension and Handling

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

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

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

For better handling and stability, the track (width between the wheels) on the Niro EV is 1.5 inches wider in the front and 1.4 inches wider in the rear than on the Mirai.

For better maneuverability, the Niro EV’s turning circle is 2.6 feet tighter than the Mirai’s (34.8 feet vs. 37.4 feet).


The Kia Niro EV may be more efficient, handle and accelerate better because it weighs about 200 pounds less than the Toyota Mirai.

The Niro EV is 1 foot, 8.3 inches shorter than the Mirai, making the Niro EV easier to handle, maneuver and park in tight spaces.

Passenger Space

The Niro EV has standard seating for 5 passengers; the Mirai can only carry 4.

The Niro EV has 10.9 cubic feet more passenger volume than the Mirai (96.6 vs. 85.7).

The Niro EV has 1.6 inches more front headroom, .3 inches more front hip room, 1.7 inches more front shoulder room, .9 inches more rear headroom, 5.9 inches more rear legroom and 1.6 inches more rear shoulder room than the Mirai.

Cargo Capacity

The Niro EV has a much larger cargo volume with its rear seat up than the Mirai (18.5 vs. 12.8 cubic feet).

The Niro EV’s standard rear seats fold to accommodate long and bulky cargo. The Mirai doesn’t offer folding rear seats.


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

To improve rear visibility by keeping the rear window clear, the Niro EV has a standard rear wiper. The Mirai doesn’t offer a rear wiper.

Standard air-conditioned seats in the Niro EV EX Premium keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The Mirai doesn’t offer air-conditioned seats.
