Toyota has ‘fully rebooted’ the second-generation Mirai fuel cell electric vehicle (FCEV) for an evolving automotive arena. While the first-generation Mirai was a four-passenger, front-wheel-drive sedan with a decidedly futuristic design, the new Mirai is Toyota’s flagship sedan, a premium, rear-wheel-drive, five-passenger sports-luxury car in the vein of the Lexus LS, on whose GA-L platform the Mirai is now based. It’s offered in XLE and Limited trim levels, with corresponding differences in equipment and interior materials.
The new Mirai is larger in every dimension except height, more powerful, and has a longer cruising range. Its four-wheel independent multi-link suspension, replacing the previous car’s strut-type front and rear beam axle, improves the car’s handling and performance, as does the change to rear-wheel-drive and the configuration of its new fuel cell system. In combination, those latter two revisions give the Mirai a near 50/50 front/rear weight distribution.
The fuel cell stack in the new-generation Mirai, like the one in its predecessor, takes in hydrogen and oxygen to create electricity without combustion to power its rear-drive motor. Water vapor is the only emissions produced during the process. The stack is about 20 percent smaller and 50 percent lighter, and now fits under the sedan’s hood. A new power control unit and other changes to the stack result in a 12-percent power increase, boosting the Mirai’s rear-drive motor output to 182 horsepower and 221 lb-ft torque (versus the outgoing model’s 151 horsepower and 247 lb-ft).
Electricity is stored in a lithium-ion battery that’s smaller, lighter, and has greater capacity than the Mirai’s previous nickel-metal-hydride battery. The battery rides between the rear seat and the trunk. Three 10,000-psi carbon-fiber-reinforced tanks hold about 11 pounds of hydrogen, giving the Mirai 402 miles of range in XLE models, and 357 in the Limited. Toyota is continuing the practice of offering up to $15,000 of complimentary hydrogen with each Mirai.
Inside the Mirai are seats trimmed in SofTex synthetic leather. The dashboard is dominated by two digital displays, an 8-inch LCD gauge cluster in front of the driver and a 12.3-inch touchscreen in the center of the dash to operate the climate control, infotainment, and navigation systems. To bring down cabin temperatures and reduce the load on the Mirai’s air-conditioning system, Toyota engineers installed extra insulation in the roof and added UV protection in the side windows.
Both Mirai models come standard with Toyota’s Safety Sense 2.5+, a suite of active safety systems with several enhanced functions. Among them is the Pre-Collision System with Pedestrian Detection, which not only registers a vehicle ahead but a bicyclist or pedestrian in front of that vehicle.
Initially the Mirai is available in California only, but Toyota says it is fully optimized for cold-weather operation, hinting that broader availability may be in the works. The Mirai XLE is priced at $49,500 with the uplevel Limited coming in at $66,000 before substantial federal and California state incentives, and potential Toyota incentives as well.
