The new hydrogen-powered machine is described as “a final-stage development model of the second-generation Mirai” and Toyota promises a major step forward in fuel cell electric vehicle (FCEV) technology. It claims the new model offers a 30% increase in driving range over the current model, which has a range of just over 300 miles, along with improved driving performance.
The new Mirai Concept is built on Toyota’s latest TNGA platform and features dramatic new styling, including a revamped front with a bold grille and a sweeping, coupé-esque rear. Toyota claims increased body rigidity and a lower centre of gravity than the original Mirai.
The concept measures 4935mm long and 1885mm wide, with a wheelbase of 2920mm. It sits on 20in wheels and retains the four-door saloon layout of the original Mirai, which was launched in 2014.
The interior has also been reworked. It features a 12.3in central touchscreen and a digital instrument display, with many of the controls moved to the centre of the dashboard. Notably, the Mirai now has five seats instead of the original’s four, which, Toyota says, has been enabled by a reworking of the hydrogen fuel cell configuration.
Aside from the claimed increase in range, Toyota has not given specific details of development work done on the fuel cell powertrain. But it says the system, including the fuel cell stack, has been entirely redesigned and offers increased hydrogen storage. It also claims the work on the system ensures a smoother, linear response, along with improved handling.
