Toyota advances hybrid engine development

Toyota is not moving away from internal combustion engines and is instead working on a new generation of hybrid engines. These engines will be more compact and use less power, and are intended for upcoming models. Unlike other manufacturers adjusting their strategies, Toyota plans to offer multiple powertrain options, including hybrids, rather than focusing solely on fully electric vehicles.

New engine design for 2028

A major change involves the 1.5-liter engine currently used in several Toyota models. By 2028, this will be replaced by a new four-cylinder engine with the same displacement. According to Journal de l'Automobile, the new engine will be available in both naturally aspirated and turbocharged versions. Toyota has also reduced the engine block's height by 10%, making it easier to integrate into future vehicles and allowing for better aerodynamic design.

Hybrid system improvements

Toyota is also upgrading its hybrid systems. The company plans to consolidate electronic components into a more compact design, reducing space and electrical losses. This will make it easier to use different powertrains on the same platform without redesigning each vehicle. The Yaris Cross will be one of the first models to use this new system, with the Corolla also affected, though not in Europe.

Larger engine for performance models

In addition to the 1.5-liter engine, Toyota is developing a 2.0-liter turbocharged four-cylinder engine. This is primarily intended for larger vehicles and sports models, which could benefit Gazoo Racing, Toyota’s performance division. In Europe, strict emissions regulations make it challenging to maintain powerful internal combustion engines, but hybrid systems could provide a solution by combining high-performance engines with electric assistance.

Compatibility with future technologies

Toyota is also exploring compatibility with renewable fuels made from biomass. These fuels are distinct from synthetic fuels produced from hydrogen and CO₂. Their viability will depend on availability, environmental impact, and regulatory acceptance. Additionally, Toyota is interested in licensing this technology to other manufacturers, including Daihatsu, Subaru, and possibly Suzuki, though some partnerships remain unconfirmed.
