Rinnakkaishybridi, also known as a parallel hybrid, is a type of hybrid electric vehicle powertrain configuration. In this system, both the internal combustion engine (ICE) and the electric motor can independently or simultaneously drive the vehicle's wheels. This contrasts with series hybrid systems where the ICE solely acts as a generator to charge the battery or power the electric motor, which then drives the wheels.

The parallel hybrid design offers flexibility in power delivery. The electric motor can assist the gasoline engine during acceleration, providing a performance boost and improving fuel efficiency. It can also power the vehicle on its own at lower speeds or for short distances, enabling electric-only driving. Conversely, the gasoline engine can propel the vehicle entirely, or it can operate in conjunction with the electric motor for maximum power output.

This architecture allows for regenerative braking, where the electric motor acts as a generator during deceleration, capturing kinetic energy and converting it into electrical energy to recharge the battery. Common examples of vehicles utilizing a parallel hybrid system include many models from manufacturers like Toyota (e.g., the Prius, though some configurations are more complex) and Ford. The ability to utilize both power sources independently or together makes the parallel hybrid a popular and efficient choice for many hybrid vehicles.
