Its peak has been diminished, all different dimensions have been elevated for the brand new Toyota Mira, a hydrogen gas cell sedan based mostly on the group’s GA-L ground plate.
|Mirai II||Mirai I||Deviation|
|4 975||4 890||+85|
|1 885||1 815||+70|
|1 480||1 535||-55|
|2 920||2 780||+140|
|1 610||1 535||+75|
|1 605||1 545||+60|
The purpose isn’t this both, however the evolution of the powertrain. Within the new system, the ability of the gas cell moved from the again to the nostril elevated from 155 to 174 horsepower regardless of a discount in dimension and cell quantity (330 as an alternative of 370). Consequently, the ability density is now 5.4 kW / liter as an alternative of three.1. The gas cell additionally turned lighter by about 10 % (25.5 kg as an alternative of 28.4). The world’s first use of silicon carbide semiconductors has additionally helped on this.
Partially, this, partly, the extra favorable fluid resistance coefficient explains that the vary has elevated by 30 % to 650 kilometers, whereas the capability of hydrogen tanks has solely halved (142.2 liters as an alternative of 122.4; 5.6 kg as an alternative of 4.6). What’s extra, this quantity is cut up between three tanks as an alternative of two – because of the brand new floorboard – for higher house utilization and a deeper heart of gravity. The scale of the system can also be diminished by a quieter and extra environment friendly air consumption system and an exhaust system that discharges air and water vapor produced as a by-product of the method: the entire system is 30 % smaller and 34 % lighter.
The battery is Li-Ion as an alternative of the earlier NiMH. Its system voltage was 310.8 V (to this point 244.8 V), and its weight was diminished by 2.3 kilograms (to 44.6 kg). The smaller battery pack suits behind the rear seat, so it doesn’t scale back boot capability.
Toyota could be very proud that the brand new TNGA floorboard household carries its heart of gravity deeply, plus it is vitally inflexible. The Mirai enhances this with a 50:50 weight distribution and multilink entrance and rear suspension for balanced driving on paper.
If you’re within the particulars, you possibly can watch the movies made by the main consultants of the mission right here.
The automobile additionally has one other trick: its on-board air filter system, for instance, makes use of a catalytic converter to rid the provision air of pollution (sulfur dioxide, nitrogen oxides, particles). It could take away 90 to one hundred pc of particles smaller than 2.5 microns from the air.
It’s anticipated that ten occasions as many Mirai will run out of the brand new mannequin as earlier than. This will likely be partly resulting from extra trendy expertise and partly resulting from a worth discount estimated at 20 %.
