Frequently Asked Questions

Common questions about comparing the 2025 BMW 4 Series and 2025 Toyota Mirai.

The BMW has a significant performance edge, boasting 255 hp and 295 lb-ft of torque against the Mirai's 182 hp and 221 lb-ft of torque. This 73 hp difference translates to noticeably quicker acceleration in the 4 Series.

How does the fuel cost difference impact long-term value?

The BMW requires premium unleaded fuel but gets 31 combined MPG, whereas the Mirai uses hydrogen. While hydrogen fuel cost varies, the 4 Series' lower upfront cost and easier fueling infrastructure often provide better perceived value for general users.

Which car is better for highway driving efficiency?

The BMW 4 Series gets an impressive 36 MPG highway, but the Mirai offers a total range of 402 miles on its hydrogen tank, making it better for range even if its efficiency metric isn't directly comparable to MPG.
