Toyota has developed a new hybrid system for 2.0-liter engines, which applies the same size-reducing, weight-reducing, and loss-reducing technologies used in the fourth-generation Prius. The new system realizes improved driving performance while retaining superior fuel efficiency. When accelerating, the hybrid system reduces engine rotations while drawing increased electric power from the battery, thereby delivering a linear and lengthened sense of acceleration.

2.0-liter Toyota Hybrid System

New Power Control Unit

The new PCU is 20% smaller, and 10% lighter than the conventional 1.8-liter model, which allows it to be placed directly above the transaxle.

New Transaxle

The motor features a new rolling-coil structure with fewer wires, and also uses a newly developed magnetic steel. A new parallel reduction gear format helps to reduce the loss in the transaxle.

Loss reduced by more than 25%
