A parallel hybrid is a type of vehicle that combines an internal combustion engine with an electric motor. Both power sources can work together or independently to drive the vehicle, improving fuel efficiency and reducing emissions. This design allows for better performance, especially during acceleration, as the electric motor can provide additional power when needed. In a parallel hybrid system, the electric motor is typically smaller and can recharge its battery through regenerative braking or by the internal combustion engine. This setup is commonly found in vehicles like the Toyota Prius and Honda Insight, which aim to offer a balance between power and environmental sustainability.
