Vehicle Overview
The Toyota Mirai, first introduced in 2014, was the world’s first mass-produced hydrogen fuel-cell sedan — a bold step in Toyota’s quest for zero-emission mobility beyond traditional battery-electric vehicles (BEVs).
Now in its second generation (launched in 2020), the Mirai has evolved into a luxury, rear-wheel-drive sedan built on Toyota’s GA-L platform (shared with the Lexus LS). It combines refined design, executive comfort, and zero-emission fuel-cell technology, offering a unique alternative to both electric and hybrid cars.
For 2025, the Mirai continues as Toyota’s hydrogen flagship, offering long range, quick refueling, and Lexus-level comfort — competing with the Hyundai Nexo and premium electric sedans like the Tesla Model S and Mercedes EQE.
