Toyota has released key details about the all-new hybrid tech that’ll be fitted to its next-generation models. Destined for use in various hybrid applications, a new four-cylinder petrol engine is a key component of the brand’s new modular powertrain programme that could yield efficiency improvements of up to 15 per cent over its current class-leading options. 

 

The new 1.5-litre unit will replace both the existing 1.8-litre four-cylinder and 1.3-litre three-cylinder petrol engines. Designed from the outset to work within a hybrid powertrain set-up, it has lower mechanical friction, improved thermal management and reduced electrical losses. It’ll also be available in both naturally aspirated and turbocharged forms.
