Tires and Wheels

The i3s’ 195/50R20 rear tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the Mirai’s 55 series tires.

For better ride, handling and brake cooling the i3 has standard 19-inch wheels. Only 17-inch wheels are available on the Mirai. The i3 offers optional 20-inch wheels.

Suspension and Handling

For superior ride and handling, the BMW i3 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.

For better handling and stability, the average track (width between the wheels) on the i3 is 1.8 inches wider in the front and 1 inch wider in the rear than the track on the Mirai.

The i3 handles at .80 G’s, while the Mirai pulls only .74 G’s of cornering force in a Motor Trend skidpad test.

For better maneuverability, the i3’s turning circle is 5 feet tighter than the Mirai’s (32.4 feet vs. 37.4 feet). The i3s’ turning circle is 3.6 feet tighter than the Mirai’s (33.8 feet vs. 37.4 feet).


The BMW i3 may be more efficient, handle and accelerate better because it weighs about 800 to 1100 pounds less than the Toyota Mirai.

Cargo Capacity

The i3 has a much larger trunk with its rear seat up than the Mirai (15.1 vs. 12.8 cubic feet).

The i3’s standard rear seats fold to accommodate long and bulky cargo. The Mirai doesn’t offer folding rear seats.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that BMW service is better than Toyota. J.D. Power ranks BMW 8th in service department satisfaction (above the industry average). With a 30% lower rating, Toyota is ranked 17th.


If the windows are left open on the i3 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 Mirai can only close the windows from inside the vehicle, with the ignition on.

To improve rear visibility by keeping the rear window clear, the i3 has a standard rear wiper. The Mirai doesn’t offer a rear wiper.

To help drivers see further while navigating curves, the i3 has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Mirai doesn’t offer cornering lights.

The i3’s optional Parking Assistant can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Mirai doesn’t offer an automated parking system.


Consumer Reports® recommends the BMW i3, based on reliability, safety and performance.
