Tires and Wheels

The Kona Electric has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the Mirai; it requires you to depend on roadside assistance and your vehicle will have to be towed.

Suspension and Handling

For superior ride and handling, the Hyundai Kona Electric 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 Kona Electric 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 Kona Electric has standard front and rear stabilizer bars, which help keep the Kona Electric flat and controlled during cornering. The Mirai’s suspension doesn’t offer a rear stabilizer bar.

The Kona Electric has variable-assist power steering, for low-effort parking, better control at highway speeds and during hard cornering, and a better feel of the road. The Mirai doesn’t offer variable-assist power steering.

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

The Kona Electric Ultimate handles at .79 G’s, while the Mirai pulls only .74 G’s of cornering force in a Motor Trend skidpad test.

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

Chassis

The Hyundai Kona Electric may be more efficient, handle and accelerate better because it weighs about 300 pounds less than the Toyota Mirai.

The Kona Electric is 2 feet, 3.9 inches shorter than the Mirai, making the Kona Electric easier to handle, maneuver and park in tight spaces.

Passenger Space

The Kona Electric has standard seating for 5 passengers; the Mirai can only carry 4.

The Kona Electric has 8.4 cubic feet more passenger volume than the Mirai (94.1 vs. 85.7).

The Kona Electric has 1.1 inches more front headroom, 1.2 inches more front shoulder room, .9 inches more rear headroom, 3.3 inches more rear legroom and 1 inch more rear shoulder room than the Mirai.

Cargo Capacity

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

Ergonomics

The Kona Electric 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 Mirai doesn’t offer a remote starting system.

The Kona Electric Ultimate has a standard heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Mirai doesn’t offer a heads-up display.

The power windows standard on both the Kona Electric and the Mirai have locks to prevent small children from operating them. When the lock on the Kona Electric 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 Kona Electric has a standard rear wiper. The Mirai doesn’t offer a rear wiper.

Recommendations

The Kona Electric was chosen as one of Car and Driver’s “Top Five/10Best Trucks” in 2019. The Mirai has never been a Car and Driver “Top Five/10Best Truck” pick.
