Vehicle Has EV Cruising Range of 26.4 km, PHV Fuel Efficiency of 61.0 km/L
Toyota City, Japan, November 29, 2011—Toyota Motor Corporation (TMC) began taking orders today through Toyota dealers around the country for the "Prius PHV" (plug-in hybrid), a gasoline-electric hybrid vehicle that can be charged using a household electric outlet. TMC will launch the vehicle in Japan on January 30, 2012.

Capitalizing on its electric vehicle (EV) and hybrid vehicle (HV) characteristics, the Prius PHV achieves high levels of both environmental and driving performance. For short-distance trips, the vehicle operates as an EV using the electric motor only, and for medium and long-distance trips, the vehicle operates as an HV. Because the Prius PHV automatically switches to HV mode when the battery depletes to a certain level, drivers do not need to worry about remaining battery power. TMC positions this vehicle, at a price obtainable by many, as a means to promote electric vehicles suitable for widespread use.
With the goal of accelerating the wide use of electric vehicles, TMC's development of the new Prius PHV focused on three areas: 1) Overwhelmingly high environmental performance, 2) product value and ease of use and 3) affordability. With its communications link, the Prius PHV goes beyond the realm of conventional cars and demonstrates the possibility of moving into a new mobility society.
With its new high-capacity lithium-ion battery fully charged, the Prius PHV's EV-mode cruising range is 26.4 km, and PHV fuel efficiency is 61.0 km/L, calculated from combined EV and HV driving modes. The vehicle's electric power consumption rate is 8.74 km/kWh*1.
To help provide more enjoyable and eco-conscious use of the Prius PHV, the vehicle comes standard with a new service called PHV Drive Support*2, which is centered on a function that connects the vehicle and owner via the Internet. Five types of services are packaged and provided free of charge to Prius PHV owners for three years. These include a service that enables remote checking through smartphones of remaining battery power and charging station locations, and allows free use of chargers (G-Station) installed at Toyota dealers and other locations.
Overcoming oil dependence is crucial to achieving a low-carbon society, and electricity is an effective means for promoting the use of alternative energy sources. Because plug-in hybrid vehicles help reduce fossil fuel consumption and CO2 emissions by using electricity, TMC positions them as the pillar of next-generation environmental vehicles after HVs. TMC aims for widespread use of next generation environment-friendly vehicles by bringing the Prius PHV to market.

High Environmental Performance only Possible with a PHV
The Prius PHV features the Toyota Hybrid System II (1.8-liter gasoline engine, electric motor and reduction gear) coupled with a high capacity, new 4.4 kWh lithium-ion battery to significantly improve EV driving performance (cruising range, power and maximum speed). Furthermore, high-efficiency energy recovery has been achieved through an increase in the amount of regenerated electricity, resulting in longer EV range and better fuel efficiency. The vehicle is also equipped with a high-efficiency on-board charger capable of charging to full in approximately 90 minutes at AC 200 V (180 minutes at AC 100 V).
Improvements in system efficiency, a reduction in body weight, and the adoption of low rolling-resistance tires have resulted in an electric power consumption rate of 8.74 km/kWh. When fully charged, the Prius PHV's EV range is 3 km longer (approximately 13% better) than the 23.4 km achieved by its forebear.
PHV fuel efficiency is 61.0 km/L, calculated from combined EV and HV driving modes, with only 38 g/km of CO2 emissions. The HV mode fuel efficiency, after the battery has been depleted, still maintains an efficiency of 31.6 km/L.
Reduced Environmental Impact with TMC's Proprietary Eco-Vehicle Assessment System (Eco-VAS)
Environmental goals were established at the start of the development phase so that environmental impact could be reduced in a well-balanced way.
Life Cycle Assessment (LCA) was carried out to reduce the total amount of CO2 emissions and other air pollutants, not just in the driving phase, but also throughout the entire life cycle of the vehicle from production to disposal (approximately 43% lower compared to gasoline-powered vehicles of the same class, approximately 9% lower compared to the base Prius). When using electricity generated from renewable energy such as solar or wind power, CO2 emissions can be further reduced.

Nimble EV Drive and a Variety of Driving Modes
The power generated by the new high-capacity lithium-ion battery enables a highly responsive and nimble drive that shows no effect of the approximately 50 kg weight increase from the base Prius.
The EV mode produces smooth and responsive acceleration, which can be maintained up to 100 km/h. When battery power depletes beyond a certain level, the vehicle smoothly transitions to HV mode.
Sound-absorbing and soundproofing materials for reducing road and engine noise have been optimally positioned, and measures have also been implemented to reduce wind noise, achieving superbly quiet operation.
In addition to the standard drive mode, the driver is able to select a number of other modes including Eco Drive Mode, Power Mode. This, in addition to the EV and HV modes, give the driver the freedom to choose the most appropriate driving style for any given situation.
Full Assortment of Features Befitting a Next-generation Vehicle
The Prius PHV comes with the following list of features while retaining the aerodynamic performance and basic equipment of the base Prius:
Exterior and Interior Design that Communicates the Prius PHV's Originality
Service to Support Enjoyable and Eco-conscious Use
To support enjoyable and eco-conscious use of the Prius PHV, the Prius PHV comes standard with PHV Drive Support, which packages the following five services and is provided free of charge to all Prius PHV owners for three years:
TMC is aware that managing household supply and demand of electricity will be important to help electric vehicles, including the Prius PHV, gain widespread use. To this end, TMC has been developing products for safe and efficient charging. Toyota Housing Corporation, a group company, will start sales of charging outlets, wall-mounted chargers and pole-type chargers for home use in January 2012. It will also launch the "H2V Manager" next January, a tool to support home-based charging that optimally controls the charging of vehicles based on the home's electricity consumption.
