The new Toyota Mirai is a radical departure from its predecessor. Whereas the original fuel-cell car looked like a bloated Toyota Prius, the redesigned model looks sleeker and more premium, making it an attractive alternative to the Tesla Model S.

It's also based on the same rear-wheel-drive as the Lexus LC 500, allowing for a more spacious cabin and more engaging driving dynamics. The standard model already looks stunning, but Toyota Customizing & Development division in Japan has made it look even better with a new body kit. These custom aero parts will be sold in Japan under the Modellista styling brand, which also recently customized the Lexus IS, at Toyota dealers in Japan.

At the front, Modellista has added a new splitter that accentuates the wider grille, along with extended side skirts and garnishing applied to the mirrors and door handles. New rear bumper slats complete the Mirai's sporty makeover. These subtle visual enhancements make the new Mirai look more aggressive than the standard car without spoiling the elegant styling while improving the car's aerodynamics.

Modellista isn't offering any new wheels, but the standard car comes with 19 or 20-inch wheels that are larger than its predecessor's. Since these enhancements are purely cosmetic, Modellista hasn't made any modifications to the powertrain.

As standard, the new Mirai's electric motor produces 179 hp, up from 152 hp in the last-generation model, and 221 lb-ft of torque. This setup enables the fetching fuel-cell car to accelerate from 0-62 mph in 9.2 seconds before topping out at 108 mph. With larger hydrogen tanks on board, the new Mirai offers a driving range of 400 miles.

US pricing for the new Toyota Mirai hasn't been announced yet, but Toyota has confirmed it will cost around 20 percent less than the old model, which starts at $58,550. Sales are slated to start in the US this month, so we should find out pricing information very soon. Sadly, Modellista's custom parts won't be sold in the US, but we're hoping Toyota's TRD department will work its magic on the new Mirai.
