The automobile sector has undergone remarkable evolution in the last 30 years, the most occurring in powertrain technology. Alternative powertrain consist of a propulsion system that does not depend upon the popular internal combustion engine. Alternative powertrain consist of hybrids engine, full battery electric, hydrogen fuel cell, compress air, gasoline kit, and others. There is significant excitement surrounding the electrical vehicles. The current powertrain technology in the automotive industry includes spark-ignited (gasoline) engines, compression engines (diesel), and electric. Furthermore, there are numerous variations on how this technology is implemented in the automotive industry such as spark-ignition internal combustion engines (gasoline), direct injection, homogeneous charge compression injection, compression ignition internal combustion engines (diesel or biodiesel), hybrid electrical vehicles (gasoline or diesel), plug-in electric vehicles, plug-in hybrid electric vehicles, extended range plug-in electric vehicles, and battery electric vehicles.
