Toyota to build petrol, hybrid and electric cars on one new platform

Toyota is developing a new platform that will allow petrol, hybrid, plug-in hybrid and fully electric cars to be built on the same basic architecture. The company says combining the different powertrain options in one structure should reduce development and production costs.

Engine centres on a new 1.5-litre unit

The core of the system is a more compact 1.5-litre four-cylinder petrol engine. It will be offered in naturally aspirated and turbocharged versions. Toyota says it developed the engine together with electric motors and power control systems.

The platform also offers more freedom in interior and exterior design. According to Toyota, the battery placement in hybrid and plug-in hybrid systems will not come at the expense of passenger space. The shared architecture will also make it possible to offer different powertrains depending on what each market needs.

Target of more than 15% fuel efficiency gain

The company plans to raise fuel efficiency by more than 15% with its new hybrid system. It expects this to come from lower mechanical friction, improved thermal management and reduced electrical losses.

New Corolla will use the platform

One of the first examples of the strategy will be the new Corolla, which is due to be unveiled in 2027. The model is expected to be offered with fully electric, petrol, hybrid and plug-in hybrid options. Toyota has not disclosed power, torque, range or pricing.
