Toyota Motor Corporation (TMC) has begun taking orders through Toyota dealers around Japan for the Prius PHV (plug-in hybrid). (Earlier post.) TMC will launch the vehicle in Japan on 30 January 2012. The Prius PHV will be sold by all Toyota, Toyopet, Toyota Corolla and Netz dealers in Japan; the sales target in Japan is 35,000 to 40,000 units per year.

With its new high-capacity lithium-ion battery fully charged, the Prius PHV’s EV-mode cruising range is 26.4 km (16.4 miles), and PHV fuel efficiency is 61.0 km/L (143 mpg US, 1.64 L/100km), calculated from combined EV and HV driving modes. The vehicle’s electric power consumption rate is 8.74 km/kWh. All cruising range and fuel efficiency figures here are based on the JC08 Japanese test cycle and verified by the Ministry of Land, Infrastructure, Transport and Tourism of Japan (MLIT).

With the goal of accelerating the wide use of electric vehicles, TMC’s development of the new Prius PHV focused on three areas: 1) high environmental performance, 2) product value and ease of use and 3) affordability. Prices (including consumption tax) start at ¥3,200,000 (US$41,000) for the entry-level S grade and run up to ¥4,200,000 (US$53,800) for the G grade with leather option.

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, 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.

Plug-in Hybrid System Specifications
Engine Type 2ZR-FXE
Displacement 1,797 cc
Maximum engine output 73 kW (98 hp)/
5,200 rpm
Maximum engine torque 142 N-m (105 lb-ft)/
4,000 rpm
Maximum motor output 60 kW (80 hp)
Maximum motor torque 207 N-m (153 lb-ft)
System maximum output 100 kW (134 hp)
Battery type / capacity Lithium-ion, 4.4 kWh

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. 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 (74.3 mpg US, 3.16 L/100km).

Toyota established environmental goals 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.

The EV mode can be maintained up to 100 km/h (62 mph). When battery power depletes beyond a certain level, the vehicle 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.

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:

  • Owner’s navigator: A service used through a smartphone, tablet PC or personal computer, to support learning of how to effectively use the vehicle.

  • eConnect: Allows the user to check, with a smartphone, vehicle status (battery power and EV range) and locations of nearby charging stations via the Toyota Smart Center (TSC). This service also provides ESPO, an eco-drive support system that displays user fuel-efficiency records and comparisons to other Prius PHVs in Japan. Additionally, a maker-optional navigation system enables remote operation through smartphones of the vehicle’s air conditioner and charging system.

  • Toyota Friend: A proprietary social networking service that provides charging and service reminders via “tweet”-like alerts. It also enables communication amongst Prius PHV users.

  • Battery care and checking: Based on battery usage information sent to the Toyota Smart Center, dealers can provide Prius PHV users with advice on how to better use the vehicle’s battery.

  • Charging service: Prius PHV users can use charging stations (G-Station) installed at Toyota dealers in Japan free of charge for an hour.

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.

Looks like my former ideal vehicle is finally here, except for one small issue - I can't afford it! Great specs, but at $40k it is priced at the edge of the world of luxury cars. With today's smaller high efficiency ICE cars getting almost 50 mpg on the cheap, gotta reconsider! Batteries have to come down in price and volumes have to go up. Ouch! And it probably has a waiting list already. Nice, but pricey! And the Volt and that far away.

The Prius starts at 32k USD in the US with delivery in March 2012.

The 90 minutes charge of the 4.4 kWh batteries is ok at home or at work but it is not good enough everywhere else. Make it a 50kW charge in 5 minutes and that would be really useful.

After the $2,500 tax credit, the standard trim (highly loaded) come out to $30k.

What is the driving speed at which the Prius PHV has a mileage of 8.74 km/kWh?

If for example at 90kmh (about 55mph), that would mean that the power required to drive 90km/h is (90km/h)/(8.74km/kWh) = 10.3 kW, wall-socket-to-wheel. That would be a good number, but I bet the 8.74 km/g is NOT at 90km/h but some lower speed.

We need some more information here.

What we really need is for Toyota to mate a small diesel with the Prius, cf. yesterday's rumours that Toyota is swapping hybrid technology for diesel technology with BMW.

Then we could really get some stellar numbers, and the plug-in ascpect would be even less relevant.

(74.3 mpg US, 3.16 L/100km) in plain hybrid mode is not bad, but a diesel would get us higher still, maybe another 30% or so, maybe 90-100mpg.

23.6 / (0.316*(1-0.30) = 106.7 mpg would be an optimistic number, just back of the envelope.

The e-range (16.4 miles) seems to be a fair improvement over previous Prius PHEV. Is the battery pack improved or is it due to other improvements or both? Anyway, 16+ miles will be enough for many early users.

Interesting the Prius falls right in line with the other production PHEV offerings. Both Leaf and VOLT can be purchased for $32k or $350/month lease. Prius owners will upgrade to PHEV on a curve - producing 3M potential sales. Once neighbors start seeing plug-ins working well, and experience the quiet, efficient, excellent mileage of EVs - sales will steepen. Why be tethered to a gas station??

Good news for the entire category.

Jus7tme,

The speed varies in JC08. Top speed is a hair over 50 mph. See the graph.

usbseawolf,

Thanks, I missed the line that said it was based on JC08.

From the plot, looks like city traffic stop-and-go with a short burst of expressway :-).

Does anyone know if the US PiP version's specs will be upgraded? I'm not sure of the exact differences between the US model and the Japan model other than the US$ 10K difference in price.

hey question what is the range for blended gasoline and electric mode if I'm going to set sail for longer trips? is it still 15 miles of 100 mpg of gasoline driving?
