The schematic of the new commercial model of the fuel cell vehicle (FCV) “MIRAI” that Toyota claims to be the “ultimate green car” was revealed on the 2nd. Compared to the first conventional generation, which had a mission to develop the market FCV, the new model has refined its appeal as a high-quality sedan, which is the essence of the car, saying that “being an FCV is part of its appeal.”
Presenting the clarified contents, including the differences of the first generation, together with the raw photos of the commercial prototype.
Aiming to be “the best Toyota sedan”

The new MIRAI, which is announced in December. It was announced as “MIRAI Concept” at the 2019 Tokyo Motor Show, and it is new to remember that the elegant styling that has a different direction from the first generation caught the eye, but it will appear almost as in the commercial model.
The first of the new MIRAI’s commitments are its proportions. Aiming to be “Toyota’s highest grade sedan,” the platform and unit design have been overhauled and revamped from the ground up. The FC stack, which is the engine, is moved from under the front seat to under the hood, one of the hydrogen tanks increased from two to three is placed in the center tunnel, and the engine is placed on the side of the wheel rear to drive the rear wheels. It has changed significantly.
These not only improve driving performance, but also contribute significantly to the proportions. The body size is 4975mm long (+85 compared to the conventional model), 1885mm wide (+70), 1470mm high (-65) and the wheelbase is 2920mm (+ 140), so you can see the character of the new MIRAI. It’s a sleek sedan that’s low and wide and has a long wheelbase.
The concept is “SILENT DYNAMISM”

The design concept is “SILENT DYNAMISM”. “The dynamic feeling of loneliness that runs through the silence,” he explained. An important feature is the low, relaxed silhouette that is typical of FR (rear-wheel drive) models. The crisp two-level headlights, the massive front grille, the sleek side bodies without clear character lines and the 6-light cockpit reminiscent of a coupe emphasize the individuality of the new MIRAI.

The interior is intended to be a personal space that combines driving pleasure with advanced relaxation. Information functions, including a large display, are built into the driver’s side and a soft pad is placed on the passenger side for a spacious feel and comfortable quality. The optional copper decoration has been developed recently. The warm metallic expression expresses a sense of advancement and luxury. The ample interior space provided by the long wheelbase is also noteworthy.

In addition, an “executive package” is also available that uses a folding headrest for the passenger seat, a power grip and a touch control panel for the rear seat. As it was intended to be Toyota’s highest-end sedan, it has equipment to meet the demand of drivers.
The cruising range is approximately 850 km and the race has evolved.

And it is the second-generation TFCS (Toyota Fuel System) that “has achieved a normal evolution with the goal of greater mass dissemination.” The FCV is a type of electric vehicle that is filled with compressed hydrogen to generate power and is powered by an engine, but the cruising range with a fill has increased to about 850 km with the new model, compared to 650 km previously. . Also, the maximum output of the FC stack is 174ps (predecessor of 155ps) and the motor is 182ps (154ps), which is a significant turn on.
Not only improving performance, but also improving productivity is a great evolution. The production cycle of the cells that make up the FC stack has been reduced from a dozen minutes per cell to a few seconds. In addition, the production time of the hydrogen tanks has been reduced by 66% and productivity has tripled. From this, we can see how serious Toyota is to popularize the FCV.

Naturally, the evolution of powertrains has a great impact on driving. FCV’s smooth, powerful and quiet acceleration, which is described as “a new sense of driving that makes you want to step on it”, is an important feature of the new MIRAI.
Furthermore, by optimally arranging heavy objects such as hydrogen tanks, an ideal 50:50 weight distribution is achieved at the front and rear. Combined with the high rigidity bodywork and the rectifying effect of the full deck under the floor, it has achieved excellent straight-line stability and steering stability. Torsional stiffness is + 25% compared to the conventional model, which is comparable to that of European competitors.

In addition, the air purification function of the new MIRAI favors the sensation of “unintentional stepping on”. Originally FCA does not emit CO2 while driving, but the new MIRAI not only emits cleaner air by removing pollutants from the air with two special filters for the air drawn in for power generation. may. Negative emissions, not zero emissions. The more you run, the cleaner the air becomes. With the “Air Purification Meter” displayed on the screen, the analog meter can intuitively know the amount of clean air each time the accelerator is pressed.
Complete safety equipment and external power supply function

Packed with advanced security features. Toyota Safety Sense is equipped with Pre-Crash Safety that detects pedestrians (day and night) and bicycle drivers (day), Lane Tracking Assist that helps maintain lane even when white lines are difficult to recognize, and a high beam system adaptable. Lane Tracing Assist also has a function to detect abnormalities in the driver, stop the vehicle and even request that lives be saved. In addition, as an advanced driving support function, it will also be equipped with advanced parking for automatic parking.
It also has an external power supply function that supplies electricity generated by the FC battery. If you use the AC100V (1500W) outlet in the car, it is possible for a general household to supply power for about 4 days (when consuming 400W). Furthermore, by using an external DC power supply system, it is possible to supply a large amount of power up to DC 9kW. In the event of a disaster, it seems to be a great advantage to be able to use FCV’s exclusive clean energy that does not emit exhaust gases.
There are two main grade systems, the advanced grade “Z” and the standard grade “G”. There’s no difference in powertrain or power, just gear, tires, and wheels. An “executive package” is prepared for each. Pricing has not been announced. By the way, the price of the first generation was 7,236,000 yen, and if you used the subsidy, you could buy it for around 5.2 million yen (at the time).
Official announcement in December

The new MIRAI stands as FCV as a result of sticking to the manufacture of high-quality sedans, unlike the first generation, which had a strong meaning as an advertising tower to expand the awareness of FCV. It can be said that its performance and high quality are definitely in the upper class of Toyota sedans. Can the new MIRAI, which advocates “diffusion” for the first generation, which sold only about 10,000 units, touch the hearts of users? The official announcement is in December. I would like to wait for its impact, including the price.
