Hybrid vehicles combine a conventional petrol engine with an electric drive. Their intelligent interaction enables significant fuel savings, reduced exhaust emissions and a special driving experience. The hybrid system automatically uses the optimum drive in every driving situation. At speeds of up to about 50 km/h, hybrids can drive short distances purely electrically. At higher speeds or when driving faster, they use the combined power of electric and combustion engines. For example, the vehicle is sometimes driven purely electrically or can call up additional power dynamically.
The hybrid can play off its advantages particularly in dense city traffic with changing speeds and frequent stop-and-go. During braking, kinetic energy is converted into electrical energy. This charges the battery, while conventional vehicles simply lose braking energy. Full hybrids generally consume around 25 percent less fuel than comparable petrol models.
