Toyota has been introducing several hybrid vehicles (HV) since 1997 as a countermeasure to the concerns raised by automobile, like CO₂ reduction, energy security, and pollutant emission reduction in urban areas. Plug in hybrid Vehicle (PHV) uses electric energy from grid rather than fuel for most short trips and therefore presents a next step forward towards an even more effective solution for these concerns. For longer trips, the PHV works as a conventional hybrid vehicle, providing all the benefits of Toyota full hybrid technology, such as low fuel consumption, user-friendliness and long cruising range.

This paper describes a newly developed plug-in hybrid system and its vehicle performance. This system uses a Li-ion battery with high energy density and has an EV-range within usual trip length without sacrificing cabin space. The vehicle achieves a CO2 emission of 59g/km, which corresponds to a fuel consumption of 2.6 liter/100 km, and meets the most stringent emission regulations in the world.

The new PHV, which was developed for conducting a large scale demonstration worldwide with about 600 units, is a forerunner of the large-scale mass production of PHV in early 2012. PHVs have the potential to become popular as a realistic solution towards sustainable mobility by renewable electricity usage in the future.
