context_page_description: The Toyota Prius Plug-in Hybrid, also known as Prius PHV and Prius Prime since 2016, is a plug-in hybrid manufactured by Toyota. Deliveries of the production model began in Japan in January 2012, in late February in the United States, and by late June 2012 in Europe. The second generation model was first available in 2016 and is currently being produced.
  The first generation Prius plug-in was produced from 2012 to 2016. Its total all-electric range in blended mode is 18 km as rated by the United States Environmental Protection Agency. The EPA fuel economy rating is 95 miles per gallon gasoline equivalent in charge-depleting and a combined city/highway rating of 4.7 L/100 km; 60 mpg‑imp in hybrid mode, the same as the conventional Prius liftback. The first generation Prius plug-in was based on a third generation Toyota Prius outfitted with a 4.4 kWh lithium-ion battery co-developed with Panasonic. A total of about 75,400 first generation units were sold worldwide through April 2016.
  The second generation Prius plug-in is called the Prius Prime in the United States and Prius PHV in Japan and Europe. It was first available in 2016 and is currently being produced.
context_section_description: Europe
  Toyota reported the following findings for the European demonstration fleet after nearly a year into the project, representing the driving experience acquired by the participants after 497,100 miles driven:
  Two thirds of commute trips traveled a distance of less than 20.1 km (12.5 mi), the expected all-electric range in EV mode.
  More than a third of the participants made long distance trips of more than 100 km (62 mi) at least once a week.
  Fuel consumption data shows that the Prius PHV consumed 36% less fuel than the comparable, best-in-class diesel vehicle, and almost 50% less than the best-in-class petrol vehicle.
  The maximum average fuel consumption figure observed was more than 2.00 L/100 km; 117 mpg‑US (141 mpg‑imp).
  United Kingdom
  Based on the results from less than one year of real-world use for the 20 Prius Plug-in demonstrators leased to EDF Energy, Toyota reported the following findings:
  Driving in electric-only (EV) mode has accounted for one third of the distance driven in the demonstration.
  The average trip distance has been 11.7 km (7.3 miles), with 59% of all journeys covering between 5.0 to 20.0 km (3.1 to 12.4 miles).
  Twenty-two percent of drivers have even been able to drive further than the official 20.1 km (12.5 miles) range in EV mode.
  Fuel consumption data indicates performance is 27% better than an equivalent diesel-powered vehicle.
  United States
  Consumer Reports field tested the Prius PHV for two weeks and reported an all-electric range between 23 to 27 km (14 to 17 miles) spent upfront at the beginning of each trip. On a 126 km (78-mile) commute trip the Prius Plug-in averaged 3.70 L/100 km; 76.3 mpg‑imp (63.5 mpg‑US) while on commute trips between 32 to 48 km (20 to 30 miles) the PHV averaged 81 miles per US gallon (2.9 L/100 km; 97 mpg‑imp) to 86 miles per US gallon (2.7 L/100 km; 103 mpg‑imp) with an EV ratio varying from 40 to 56 percent during those trips.
  The California Center for Sustainable Energy tested two Prius Plug-in with 13 different drivers during seven weeks and reported an average combined fuel economy of 83 miles per US gallon (2.8 L/100 km; 100 mpg‑imp) on an average round trip commute of 35 km (22 miles). The best average attained was 2.40 L/100 km; 117.6 mpg‑imp (97.9 mpg‑US) on an average round trip commute of 77 km (48 miles).
  Motor Trend field tested the Prius PHV for 32 days and reported average CO
  2 emissions of 80 g/km (0.28 lb/mile), an average all-electric range of 18.8 km (11.7 miles), and an average combined fuel economy of 3.34 L/100 km; 84.5 mpg‑imp (70.4 mpg‑US) over the 3,030 km (1,880 miles) accumulated during their trial.
  Based on the testing with 160 consumers across the United States, Toyota reported that users are charging the Prius Plug-in more frequently than the carmaker anticipated, with about 10 charges per week, but the electricity cost was lower than they thought, at about US$150 for the entire six-week trial.
