Currently reading: Toyota reveals Prius FFV concept that can run on ethanol
Hybrid Flexible-Fuel Vehicle designed to run on sugar cane-based ethanol as well as regular petrol

Toyota has developed a modified version of the hybrid Toyota Prius for the Brazilian market that can run on both petrol and ethanol.

The Prius Hybrid Flexible-Fuel Vehicle (FFV) prototype, capable of running on both conventional petrol and plant-based fuels such as ethanol, has been developed by Toyota with the support of the São Paulo state government. It is designed to highlight a way to reduce CO2 emissions in Brazil.

New Toyota Auris launched with more powerful hybrid

By using E100 ethanol, which is 100% renewable, alongside the standard Prius hybrid powertrain, Toyota claims the FFV is significantly more environmentally friendly than a regular petrol-electric hybrid powertrain. Brazil is the world’s second-largest producer of ethanol, which is created using reproduced biomass from fermenting sugar cane.

While the FFV is a prototype – it's part of a project to commercialise the technology in Brazil – Toyota will collect data through real-road testing to gauge the system’s reliability, durability and powertrain performance.

The prototype is part of Toyota’s wider efforts to reduce vehicle CO2 emissions by 90% by 2050 compared with 2010 levels.

E10 petrol, a mix of 90% petrol and 10% ethanol, is widely used in the US and runs in standard vehicle engines.

Toyota is also building a hydrogen generation station at Port of Long Beach, California, that uses biomaterial to generate water, electricity and hydrogen.

And if it were to use 100% Ethanol that was sourced from Corn you only need 16kg of it to produce the equivalent of one gallon of petrol. Try telling that to a staving person in Afica or someone who has watched a rainforest being cleared in Brazil.
