Compare the2025 Toyota MiraiVS 2025 BMW i4

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 BMW i4 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 i4 doesn’t offer a whiplash protection system.

Both the Mirai and i4 have rear cross-traffic warning, but the Mirai has Parking Support Brake (automatically applies the brakes) to better prevent a collision when backing near traffic. The i4’s Cross Traffic Warning doesn’t automatically brake.

Both the Mirai and the i4 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and driver alert monitors.

Toyota’s powertrain warranty covers the Mirai 1 year and 10,000 miles longer than BMW covers the i4. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the i4 ends after only 4 years or 50,000 miles.

There are almost 4 times as many Toyota dealers as there are BMW dealers, which makes it much easier should you ever need service under the Mirai’s warranty.
