Parallel Hybrid

The motor sits between engine and gearbox. It uses a conventional gearbox. Mild hybrids are a simple form. Many plug-in hybrids from European brands use a parallel layout with a motor integrated in the automatic or dual-clutch gearbox. The engine can be decoupled by a clutch for electric driving. This design keeps the familiar driving feel of a conventional gearbox.

Both power sources connect to the driveline.

Electric range is limited. Clutch systems add complexity.
