Toyota Motor Corporation has updated its "Sora1" Fuel Cell Electrified Vehicle bus (FCEV bus). The improvements are to be found in the 'preventive safety performance' through the use of ITS functions (ITS: Intelligent Transport Systems). Additionally, the Sora's transportation capacity, speed, and punctuality have been expanded. Soraan is an acronym for Sky, Ocean, River, Air, representing the earth's water cycle.

The updated model includes a function that cautions the driver when making right turns at intersections (blind spot), and a system that enables passengers to activate an emergency stop in urgent situations, such as if the driver suddenly falls ill.

The updated Sora is equipped with a new system that shares information on the distance between the vehicles, to prevent two or more buses traveling in a convoy from being separated at traffic lights and bus stops, leading to overall improvements in transportation capacity, speed, and punctuality of the buses. The improvements made in this update are: ITS Connect Vehicle-to-Infrastructure Communication System (DSSSDriving Safety Support Systems); ITS Connect Communicating Radar Cruise Control; Infrastructure devices and vehicles share information on oncoming vehicles, pedestrians, and traffic lights to increase driver awareness; Red Light Caution and a 'Red Light Deceleration Assist'; Signal Change Advisory; Emergency Driving Stop System; Collision Warning System that considers the safety of standing passengers and seated passengers who have not fastened their seatbelts, and supports the driver in avoiding collisions by assisting with steering.

The Toyota Sora has a Toyota FC Stack (solid polymer electrolyte). The AC synchronous motor has an maximum output of 113 kW×2 (154 PS×2) and a maximum torque of 335 Nm×2 (34.2 kgf・m × 2)
