Not a Tesla, the hare in the fable, despite its refueling twenty minutes at 100-kw in their superchargers. The Toyota Mirai is the tortoise in the fable, which wins the race, because you three minutes are enough to recharge. That's why Toyota conceived as a technology for the future of long commutes ... clean. Toyota Mirai battery is relatively small, the same of NiMH (nickel metal hydride) Toyota Camry Hybrid, but the constant source electricity for propulsion is provided by a fuel cell. Battery, like the Toyota Prius and other Toyota hybrids, serves to restore power to retain or braking, but also Mirai battery serves to initiate movement of the vehicle or support extra power when accelerating strong, while the fuel cell is set to run at system and deliver power.
According to the father of Mirai, Yoshikazu Tanaka project, the fuel cell takes little to wake Mirai, about 0.7 sec because the compressor supplies pressurized air with the oxygen necessary to recombine with the hydrogen. The fuel cell is able to provide in its operation 114 kW of electrical power, sufficient to power the 113 kW electric motor that drives the front wheels Toyota Mirai. If you open the hood, you will not see this electric motor from the Lexus RX 450h, hidden by electronics. It does not take gearshift, limiting its maximum speed to 178 km / h, because energy losses are very high. However, on our first tour of German motorways (already tested with specifications for the US) we could see sustained speed, both downhill and steep slopes light above 180 km / h without problems and a incredible silence. Announces consumption 0.7 kilos of hydrogen per 100 kilometers. A very low value, the result of a nominal output of the fuel cell around 85 percent. The caveat is that hydrogen costs about 10 euros per kilogram and the virtual absence of supply points. This is the purpose of Toyota Mirai, put several thousand cars in circulation, the electric car show that hydrogen is viable and encourage States to promote the installation of "hidrogeneras". With the same objective Toyota has released 5,680 patents until the end of 2020, so that other manufacturers can be added to the project. According to estimates by Toyota in world hydrogen is produced as to circulate 250 million Mirai at 20,000 annual kilóometros. I must say, it is much cheaper Industrial hydrogen, no hydrogen obtained by electrolysis of water using renewable energy, 9.5 or 9.99 euros per liter.
Silence and strength in the Toyota Mirai
Does not accelerate like a Tesla impress you or BMW i3, but the Toyota Mirai is able to officially lose 10 seconds, significantly faster than a VW e-Golf. So even though the Mirai might seem heavy, with 1,850 kilos and pushing so soft that it seems to run much. Tanaka is responsible for an achievement, as they have managed to lower 100 kilos in weight target set for the project. In addition, its external lines camouflages the Toyota Mirai is a big car, because It measures 4.89 meters long, something less than Audi A6, for example, although a distance between minor axes. Hablarn mechanical power 335 Nm of torque, which appear at the time the engine starts moving. This means that on wet roads, the traction control system has enough work to prevent wheel spin if you use the accelerator generously. Nothing disturbing, because as driver of the Toyota Mirai only perceive softness and ease. Silence presides wheeling Toyota Mirai, an incredible silence rolling 100 km / h You have the feeling of running at 80 km / h or less. Everything in this special car is responsible for this mutes, from aerodynamics to the double side windows or the roll of insulation. Unlike other electric, there's that high-pitched beep inverter itself, to feed the engine. In the Toyota Mirai not hear nor air conditioning fan. To say that the most striking in the acoustic section are clean when you reach the end of travel ... only heard, to step on a not very high, audible, but hardly recognizable as the compressor noise, (At least, it is what tells you the logic that should be working more than usual).
The Mirai is maximum comfort
At the wheel of Mirai or as a companion, one feels incredibly comfortable during any movement. The frame of the car is the Toyota Prius +, reinforced all that is seen fit. And for Mirai has taken the rest, for example, invisible behind their low fully enclosed (Since there is no need to expel heat from the exhaust) there is a cover carbon fiber to protect the fuel cell. Suspensions seek filter it all, the car treads well and only paved area we notice "rough" the noise coming like, as if the hyper-rigid body, reminding superdeportivos carbon fiber. This time the car comes with set-ups for the European driver. You may swing, but the driver gives a mild electric steering, good touch, while the brake pedal does not feel braking rebound typical of most electric and hybrid. Simply put, the transition between mechanical and electric brake not feel, just so you do not feel when the battery is pushing and when gives the baton to the fuel cell for electricity to the motor. Is I easy to describe the operation of the propulsion system Toyota Mirai: Lecture.
Has "buts" Toyota Mirai
The disadvantages of Toyota Mirai is the Toyota itself has sought consciously. They could have made an SUV, so fashionable, but they did not want to do a car commercial ... for now. They made a sedan body, three volumes, due to its advantages in terms of aerodynamics, so important in an electric car. A body of three volumes meant for engineers a challenge, which required maximum miniaturize components. Why they are proud, though habitability is not your forte, He walks like a glove, but spare space or foot rear passenger (under the seat is the fuel cell), or their heads. Moreover, it is only four seats and the trunk is more typical of a Toyota Auris Toyota Avensis that a dimensions.
In many respects the Toyota Mirai not enough in comparison with his brother "little" Avensis. Knobs and handles do not get to touch or materials on this, although it is true that the presentation of the Mirai driving position is innovative and attractive. Look no electric parking brake, for example. Splurging on technology, even if they have reduced costs by 20 times compared to the first prototypes, Toyota Mirai sold about 66,000 euros in European markets (now in Germany, Denmark, Britain and Belgium, for example to Spain is not yet defined arrival). maybe the purchaser of a car like Mirai, much more exclusive than a Lexus, could expect a more dazzling equipment, even if thereby increasing the bill. In doing so, perhaps Toyota did not want the client despistase with the technological aspects of Mirai "vulgar". Or that did not make sense for Toyota expensive this experiment on a gigantic scale, because in reality They try all sales are for leasing, for about 1,000 euros per month, in order to recover the car after four years and thoroughly study results. The Toyota Mirai will be manufactured at a gentle pace (three fuel cells per day are made), because it is only to make perfect cars, without fail, to lay the foundation of a cell car reliable, trustworthy and infallible fuel. After that, they hope to come true mass production under the new architecture and manufacturing of Toyota tnga which opens with the new Toyota Prius.
For all the above chosen for Mirai experienced veterans and NiMH batteries. So his power may seem fair to the weight you have. The intention is that the fuel cell lasts as any current combustion engine without losing power over time and no problems during its lifetime, with a five-year warranty for all electrical part and three years for the car. Welcome to the car of the future, because the future means Mirai in Japanese. Toyota has revealed its intention that 2050 produce no other cars that who have some electric motor. Mirai why this is but the first of a vision of a more sustainable world (recently presented at the Toyota Challenge 2050), beginning to show that the hydrogen car is now available. What ?, lower costs that has always been a specialty of Toyota and fuel cell car would not have to be the exception ...
