GREEN ZONE
organisation from an automobile company to a mobility service company. Toyota aims to contribute to the improvement of both customers’ lives and society, as a whole, by creating sustainable solutions. At the core of this lies the company’s desire to innovate, inspire and contribute to a better future, and the Sora epitomises that objective. The bus doesn’t emit CO2
or
substances of concern, leaving only water vapour in its wake. The system also has a 9kW external power supply with a capacity of 235kWh, which can be utilised as an emergency power supply, when required and provides enough juice to keep lights on for six hours a night, for fi ve nights. In developing the Sora, Toyota’s created buses that give customers the freedom of mobility while serving as a local attraction. The vehicle has a capacity of 79
in total (22 seated, 56 standing and a driver), and contains horizontal seats with an automatic storage mechanism, considered a fi rst in Japan. The seats automatically store fl at when not in use, off ering more space and improved
convenience for passengers with strollers or wheelchairs. Added safety features include eight
high-defi nition cameras fi tted inside and outside the vehicle, which improve peripheral monitoring. These detect pedestrians and cyclists around the bus and warn of impending obstacles through sound notifi cations and images. The vehicle also has a control function that enables smooth, lurch-free acceleration from being completely stationary, resulting in a more comfortable ride. The bus has an automatic arrival
control system, which steers it 3-6cm from the bus stop edge and within 10cm of the stop’s fore or aft position, allowing passengers to board more easily – especially those with walking aids or wheelchairs.
Toyota expects to introduce over 100 fuel cell buses ahead of the Olympic and Paralympic Games in 2020, operating mainly within the Tokyo metropolitan area.
HOW IT WORKS At the core of the Toyota Fuel Cell
System is the Toyota fuel cell stack, which generates electricity by the chemical reaction of water and oxygen, and the battery. The system generates electric power to drive the bus and emits only water – making this a clean power source.
OPERATION Step 1: Air/oxygen taken in. Step 2: Oxygen and hydrogen supplied to fuel cell stack.
Step 3: Chemical reaction generates electricity and water.
Step 4: Electricity is supplied to the motor.
Step 5: Motor is activated and the bus moves.
Step 6: Water vapour is released.
TOYOTA’S DESIRE IS TO INNOVATE, INSPIRE AND CONTRIBUTE TO A BETTER FUTURE, AND THE SORA EPITOMISES THAT OBJECTIVE.

A WORLD-FIRST FLEXIBLE-FUEL HYBRID PROTOTYPE HAS LAUNCHED
Toyota recently unveiled the world’s fi rst hybrid fl exible-fuel vehicle (the Hybrid FFV) in São Paulo, Brazil. The prototype is a combination of a fl exible- fuel vehicle (which can be powered by both gasoline and alternative fuels) and Toyota’s hybrid system, which combines a combustion engine with an electrical powertrain. The Hybrid FFV has the potential to
drastically reduce total CO2 emissions,
as it not only has high energy-effi ciency and low emission levels, but leverages CO2
re-absorption capacity of ethanol,
a plant-derived 100% renewable fuel. Toyota’s initial studies indicate a great advantage in environmental performance and, if fuelled by only sugar cane-based ethanol (E100 fuel), the results are even better. This prototype moves Toyota a step closer to its Environmental Challenge
2050. The company’s pledged to reduce vehicle CO2
emissions by 90%
in comparison with 2010 levels and, by 2050, to completely eliminate CO2
emissions from the vehicle life-
cycle, including materials, parts and manufacturing. Steve St Angelo, Senior Managing Offi cer of Toyota Motor Corporation,
Acting CEO of Toyota Latin America Region & Caribbean, as well as Chairman of Toyota do Brasil, says: “I’m very proud of our Toyota do Brasil engineers who worked closely with our engineers in Japan to develop the world’s cleanest hybrid vehicle that uses ethanol for our Brazilian customers. The invention demonstrates our journey in providing a new mobility society.”
