  1. Hybrid cars and their importance

  2. A hybrid vehicle is a vehicle that uses two or more distinct power sources to move the vehicle. The term most commonly refers to hybrid electric vehicles (HEVs), which combine an internal combustion engine and one or more electric motors. However, other mechanisms to capture and use energy are included. • The Toyota Prius is the world's top selling hybrid electric vehicle, with cumulative global sales of over 3 million units by June 2013.

  3. Heavy vehicles • Hybrid power trains use diesel-electric or turbo-electric to power railway locomotives, buses, heavy goods vehicles, mobile hydraulic machinery, and ships. Typically some form of heat engine (usually diesel) drives an electric generator or hydraulic pump which powers one or more electric or hydraulic motors. • There are advantages in distributing power through wires or pipes rather than mechanical elements especially when multiple drives—e.g. driven wheels or propellers—are required.

  4. Rail transport • EuropeThe new Auto rail à Grande capacity (AGC or high-capacity railcar) built by the Canadian company Bombardier for service in France. • ChinaThe First Hybrid Evaluating prototype locomotive was designed and contracted by rail research centre MATRAI in 1999 and the sample was ready in 2000. • JapanThe first operational prototype of a hybrid train engine with significant energy storage and energy regeneration capability was introduced in Japan as the KiHa E200. • North AmericaIn the US, General Electric introduced a prototype railroad engine with their "Ecomagination" technology in 2007.

  5. Road transport, commercial vehicles • Early hybrid systems are being investigated for trucks and other heavy highway vehicles with some operational trucks and buses starting to come into use. The main obstacles seem to be smaller fleet sizes and the extra costs of a hybrid system are yet compensated for by fuel savings, but with the price of oil set to continue on its upward trend, the tipping point may be reached by the end of 2015.
