Would a 15% improvement in fuel efficiency make you more likely to choose a hybrid vehicle?
Toyota has announced a new 1.5-litre naturally aspirated four-cylinder hybrid engine aimed at boosting overall fuel economy. This powertrain is intended to replace both current 1.8-litre and 1.5-litre three-cylinder configurations.
Why it matters
The engine utilizes a common architecture to streamline engineering and production costs across hybrid, plug-in hybrid, and electric vehicle lineups. This strategy enables greater efficiency in manufacturing while supporting compatibility with carbon-neutral fuels.
The new 1.5-litre engine design aims for fuel efficiency gains exceeding 15% compared to existing powertrains. Currently, the manufacturer uses a 1.5-litre three-cylinder setup in models like the Hyryder SUV, which produces 115 PS and 141 Nm of torque.
The players
