Toyota has been introducing several hybrid vehicles (HV) as a countermeasure to concerns related to the automotive mobility like CO2 reduction, energy security, and emission reduction in urban areas. A next step towards an even more effective solution for these concerns is a plug-in hybrid vehicle (PHV). This vehicle combines the advantages of electric vehicles (EV), which can use clean electric energy, and HV with it's high environmental potential and user-friendliness comparable to conventional vehicles such as a 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 and meets the most stringent emission regulations in the world. The new PHV is a forerunner of the large-scale mass production PHV which will be introduced in a year.

This paper introduces a minivan with a newly developed hybrid system known as THS-C (The Hybrid System - CVT). This hybrid system employs a highly efficient engine, a high performance exhaust emission control system, a high efficiency metal belt CVT, and a super efficient motor. System control of the engine, motor and CVT optimizes the operation of both the motor and the engine. With these improvements, this new vehicle achieves over 80% better fuel economy than a comparable conventional vehicle. Exhaust emissions are dramatically reduced using precision control during the engine starts and stops.
