New hybrid engine design

Toyota has introduced a new 1.5-liter four-cylinder gasoline engine tailored for hybrid systems. The engine will come in both naturally aspirated and turbocharged versions, aiming to reduce fuel consumption by over 15 percent compared to existing models.

Replacing older engines

The naturally aspirated version of the new engine is meant to replace the current 1.8-liter four-cylinder and 1.5-liter three-cylinder engines used in several hybrid models. The new engine will be shorter than its predecessors, allowing for a lower hood design that could improve aerodynamics and further reduce fuel consumption.

Silicon carbide technology

Toyota is also focusing on power electronics that use silicon carbide, a material that reduces energy losses during the conversion of electric current. This technology, already used in some electric vehicles, could enhance the efficiency of hybrids.

Fuel efficiency improvements

The company aims to achieve an overall energy efficiency improvement of more than 15 percent with its future hybrid engines. The Yaris currently has a fuel consumption of 3.8 liters per 100 kilometers and could potentially go below 3.3 liters per 100 kilometers with the new technology.

Future deployment plans

Toyota has not yet provided a specific schedule for the deployment of the new engine, but the next generation of the hybrid Corolla, expected around 2028, appears to be a likely candidate. The manufacturer has also indicated that it intends to develop the sale of its hybrid engines and systems to other companies in the coming years, though no new partners have been announced at this stage.

Commitment to hybrid technology

Toyota continues to emphasize its commitment to hybrid technology, despite ongoing advancements in fully electric vehicles. The company sees hybrid systems as a crucial part of its strategy to reduce emissions and improve fuel efficiency across its vehicle lineup.
