Toyota Motor Corporation (Toyota) has announced that sales of the “Sora 1”, the first fuel cell bus to receive vehicle type certification in Japan, have begun.
Toyota expects to introduce over 100 fuel cell buses, mainly within the Tokyo metropolitan area, ahead of the Olympic and Paralympic Games Tokyo 2020.
Last year, Toyota launched the “Start Your Impossible” global corporate initiative to transform the company from an automobile company to a mobility service company.
Toyota aims to create a bus that works for and supports society, so the Toyota Fuel Cell System (TFCS) has been leveraged in the Sora for its environmental friendliness and ability to serve as a power source in the event of a disaster. (pictured above)
The Sora offers the following specific features
- High environmental performance and the joy that is derived from FC technology
- The Toyota Fuel Cell System (TFCS), which was developed for the Mirai fuel cell electric vehicle (FCEV), has been leveraged to realise high environmental performance with no CO2 emissions or Substances of Concern (SoC) emitted when in operation, as well as quiet comfort with minimal vibration
- The Sora is equipped with a high-capacity external power output device, which can provide high output and a large capacity of electricity supply (9 kW maximum output, and electricity supply of 235 kWh*2) and has potential use as an emergency power source following disasters
- High-capacity external power output device
- Universal design and function that provides everyone with greater freedom of movement
- Horizontal seats with an automatic storage mechanism
- The Sora’s seats are automatically stored when not in use, improving comfort and convenience for passengers with strollers and wheelchairs as well as other passengers.
Field of vision support camera system (bus peripheral monitoring function)
Eight high-definition cameras fitted inside and outside the vehicle detect pedestrians and bicyclists around the bus providing a field of vision support camera system. When at bus stops, the system warns the driver of surrounding pedestrians and bicyclists through sound notifications and images thereby improving safety.
Acceleration control function delivers improved safety
The acceleration control function suppresses sudden acceleration and enables smooth acceleration from complete stops in consideration of the safety of standing passengers. Also, as the bus is not motor operated, there is no gear shifting, resulting in minimal lurching.
The design pursues stereoscopic shaping that significantly differs from the hexahedron (box shape) of conventional buses. It also uses LED technology for the front and rear lights. Such design features make the FC bus instantly recognisable.
