How a hybrid car works depends on its design and how it acquires energy. Hybrids can use both engines at the same time to increase power, or rely on one depending on the driving type. As their name suggests, hybrid cars are a combination of two types of cars – electric cars and traditional gasoline-powered cars, also known as internal combustion engine vehicles (ICEs).Hybrid cars have combustion engines that run on gasoline and an electric motor that runs on battery power with an attached rechargeable pack for electric-powered driving.
