Toyota Advances with Exclusive Flex Hybrid Engine; Competitors Race to Keep Up with the Pioneering Technology that Combines Ethanol and Electricity and Redefines the Future of Mobility in Brazil
The flex hybrid technology, developed by Toyota and manufactured in Brazil since 2019, is repositioning the country as a strategic hub for sustainable vehicles. The Toyota Corolla flex hybrid, launched five years ago, was the world’s first car to combine an electric engine and a flex engine, capable of running on gasoline or ethanol. From this move, the Japanese automaker established a leading position in the flex hybrid sector in Brazil.
Meanwhile, other manufacturers are still racing to reach the same level of efficiency and production scale. The system created by Toyota has become a benchmark in the market and is shaping the future of automotive electrification in the country.
Toyota Flex Hybrid: Leadership Since 2019 in the Brazilian Market
The Toyota Corolla flex hybrid, launched in 2019, was a global milestone. Locally manufactured, the model uses a 1.8 combustion engine combined with two electric motors, delivering a total power of 122 horsepower. This technology was designed to run on gasoline or ethanol, using the energy regeneration system during braking to maintain the battery charge, without the need for external recharging.

In 2021, the Corolla Cross flex hybrid expanded the brand’s portfolio with the same technological base. And in 2025, Toyota promises to launch the Yaris Cross flex hybrid, also with local production. These moves consolidate the automaker’s leadership in the segment, with a functional system that is already homologated and adapted to Brazilian fuel conditions.
What is Flex Hybrid Technology
A hybrid car with ethanol is one that combines an electric motor with a combustion engine, capable of operating on gasoline or ethanol. This system provides greater energy efficiency and lower emissions of pollutants. By using ethanol, CO₂ emissions can be reduced by up to 70% compared to conventional gasoline models.
In the version used by Toyota, the battery recharging occurs autonomously, either through the thermal engine or from the energy generated during braking. This feature eliminates the need for plugs or charging stations, a significant advantage for Brazilian consumers.
Toyota Rivals Seek Alternatives with Launch Planned by 2028
Since the launch of the first Toyota flex hybrid, several brands have announced plans to develop their own technologies in Brazil. Fiat, for instance, launched the Bio-Hybrid system in 2024, classified as a mild hybrid. This system will be incorporated into the Jeep Compass only in 2027.
Meanwhile, Honda plans to launch its first flex hybrid by 2028. The development is still in the conceptual stage and will initially focus on compact models, according to insider information.
Volkswagen, in turn, is working on plug-in hybrid versions for the T-Cross and the Nivus, with promises to integrate a flex engine into the system in the coming years. However, there is still no hybrid car with ethanol in circulation from Toyota’s competing automakers.
Barriers to the Popularization of Flex Hybrids
The large-scale adoption of flex hybrid technology faces three main obstacles: development costs, the need for localization of components, and the time required to adapt vehicle platforms.
The use of ethanol requires components that are more resistant to corrosion and high temperatures. This, combined with the costs of batteries and electronics — still predominantly imported — drives up the final price of vehicles. Toyota has overcome these barriers by investing in the localization of component production and by already mastering hybrid technology since the launch of the Prius in 1997.
For competitors, localization remains a challenge. Stellantis, the group that controls brands like Fiat, Peugeot, and Jeep, announced an investment of R$ 32 billion in Brazil by 2030, part of which is earmarked for the development of hybrid systems with flex engines. The goal is to achieve the level of maturity already demonstrated by Toyota in recent years.
Toyota as a Benchmark in Electrification with Ethanol
Toyota’s competitive advantage lies in the experience gained and in the adaptation of hybrid technology to the characteristics of Brazilian ethanol. Since the Prius, the automaker has gathered data and practices that allowed them to adjust engines, electronics, and energy management systems for the use of biofuel.
As a result, the brand has achieved high consumption efficiency and environmental performance while maintaining the economic viability of local production. Toyota’s flex hybrid technology is already in operation with thousands of units sold and positive results in the national market.
The automaker is also taking a cautious stance regarding full electrification, believing that the hybrid car with ethanol still represents the most suitable solution for Brazil, considering the infrastructure and consumer profile.
Yaris Cross Will Arrive in 2025 to Strengthen Toyota’s Leadership
The next step for Toyota will be the launch of the Yaris Cross flex hybrid in 2025. The model will be positioned as a compact SUV, maintaining the same technological base as the Corolla and Corolla Cross siblings. The new vehicle will feature local production and is expected to expand the brand’s reach among consumers interested in sustainability without sacrificing the practicality of the fuels already available.
With three models equipped with flex hybrid technology in line by the end of 2025, Toyota is enhancing its competitive advantage and making it difficult for rivals to enter the segment. The expectation is that the Yaris Cross will reinforce the brand’s presence in the more accessible price ranges, catering to a growing demand for vehicles with lower consumption and environmental impact.
