New hybrid engines for Toyota models

Toyota plans to introduce new hybrid engines for the Yaris Cross and Corolla models by 2028, according to a report from October 19, 2026. These engines will replace the current 1.5-liter turbo hybrid system used in the Yaris since 2020.

Design improvements with a four-cylinder engine

The new hybrid system will use a four-cylinder engine with the same displacement as the current three-cylinder model. Thiebault Pâquet, vice president of R&D at Toyota Europe, stated that this change will reduce the vehicle’s height by 10%, improve aerodynamics, and enhance acoustic and vibration comfort.

Targeting different vehicle segments

The new 1.5-liter engine will be used in vehicles in segments A, B, and C, replacing the current 1.5T and 1.8 engines. It will be available in naturally aspirated versions and will offer increased power outputs, ranging from 116 to 140 horsepower.

Turbocharged version for larger models

A turbocharged version of the 1.5-liter engine will replace the naturally aspirated 2.0 and 2.5 engines on models in segments C+, D, and E. This engine will be available in hybrid or plug-in hybrid versions. Toyota has also introduced a new 2.0-liter turbo engine compatible with hybrid systems to support its Gazoo Racing models.

Fuel efficiency improvements

Toyota claims the new hybrid system will reduce fuel consumption by 15%, thanks to an optimized engine efficiency of 41%, a compact electric machine with higher rotation speed, and reduced current losses in power electronics using silicon carbide (SiC).

Future goals and technology sharing

Toyota is not focusing on increasing autonomy in 100% electric mode but on system efficiency and transmission improvements to eliminate the "moulinette" effect. The company is working on achieving 50% engine efficiency using lean burn combustion and plans to sell its hybrid technology to other manufacturers.

Compatibility with renewable fuels and future models

The new 1.5 and 2.0 engines will support renewable fuels from biomass, allowing internal combustion engines to be sold beyond 2035 in Europe. The hybrid system will be implemented on new models starting in 2028, including the Corolla 4-door and the replacement for the Yaris Cross, which will be produced in hybrid and electric versions.

Potential partnerships and market expansion

Toyota is likely to share its new hybrid technology with its constellation brands, such as Daihatsu or Subaru, and there are rumors of a joint project with Suzuki in Europe.
