As hybrids use a standard combustible engine with the assistance of the electric power, they are capable of travelling around 500 miles on a full tank of fuel. This is based on motorway driving. However, whilst being driven around towns and other low speed areas, electric mode offers improved performance and economy when compared to an average petrol or diesel car and often release zero CO2 emissions. When using electric power mode only, a hybrid will usually offer an additional 20-30 miles of driving at about 30mph. The Hybrid vehicles also tend to have a slightly smaller fuel tank than that of standard vehicles.
Almost all fully electric cars will be able to comfortably travel at least 100 miles on a single, full charge. However, newer modern electric vehicles are now boasting ranges of over 300 miles on a single charge.
