The Toyota Prius (XW10) is a compact hybrid car Toyota discoveries between 1997 and 2003 in Japan. The Toyota Prius (XW10) divided the NHW10 and NHW11 counterpart, both represent the first generation of Prius series. The Toyota Prius is the first mass-produced hybrid vehicle, and was released 2 years before other manufacturers. Although NHW10 was available only in Japan, and later be presented to the international market in September 2000 and NHW11. Toyota sold the first generation of about 123,000 Prius. Toyota Prius (XW10) series significant as the first car based on Toyota MC platform.
Toyota Prius (XW10) Planning and Concept
On January 16, 1992, the Toyota Motor Corporation announced the Earth Charter, a document outlining the goals to develop and market low emission vehicles. In September 1993, Toyota R & D Executive Vice President Yoshirio Kimbara created G21, a committee to research cars of the 21st century. On February 1, 1994, the first meeting of the G21 group of official project happen. Group determined by the G21 goal to build a vehicle resource and the environment while retaining the benefits of modern vehicles. The development effort was led by Takehisa Yaegashi, who was also to build a car bridged the gap between electric and gasoline powered cars.
In 1994, Toyota executive Takeshi Uchiyamada was given the task of creating the new car that can be both fuel efficient and environmentally friendly. Toward the end of 1994, the G21 team designed the concept car with a hybrid engine for the 1995 Tokyo Motor Show. The vehicle called “Prius,” Latin for “before” or “before.” It was shown on October 27, 1995. Toward the end of 1996, began to test drive.
After reviewing hybrid designs than 100, a group of engineering remained a hybrid engine design based on the 1974 TRW patent, but many technical and engineering problems had to be solved in three years that the group was given to bring the Japanese car market, a goal barely achieved as the Prius first went on sale in December 1997. a problem The main was a long time the battery, which is needed to remain within the past 7 and 10. Engineers came solution was to keep the battery between 60% and 40%, becoming the “sweet spot” to extend the battery life and possibly other parts of the car. Toyota spokesman stated that “Toyota chose this name because the car Prius is the predecessor of cars to come.”
Toyota Prius (XW10) Market
The XW10 initially manufactured at the plant Takako, but later moved to Tsutsumi plant in Toyota City, Japan.
Toyota Prius (XW10) Domestic Launch Model
The first Toyota Prius, model NHW10, went on sale on December 10, 1997. It was available only in Japan, although to be placed privately at least the United Kingdom, Australia, and New Zealand. Many of these vehicles are now being exported second hand cars New Zealand and other countries. In New Zealand, there is a report that the high voltage battery failure is common among the gray the NHW10, which are not supported by the official distributors outside Japan.
To handle the voltage between the battery and electric motor, the semiconductor core inverter unit was modeled on the heavy-duty transistors are used on the Shinkansen bullet train. The first model NHW10 Toyota Prius was rolled out of Takoka factory Toyota in Toyota City, Aichi near Nagoya in December 1997, followed by the start of sales in two years Japan only. As uncovered by engineer exam, the NHW10 Prius was in danger of working in groups hotter weather and higher altitudes; because, examples of the ancient instrument panel warning indicator should hybrid system in danger of shutting down. This gauge, designed in the shape of a turtle, used until 1999.
The Toyota Prius first generation, when introduced, was the first mass-produced gasoline-electric hybrid car in the world. Japan sales goals amounted to 12,000 units annually, at a price of US $ 16,929 each vehicle. Competitors and analysts estimated that the first generation Prius costs as much as US $ 32,000 to produce, which means that each model NHW10 sold at a loss. Presentation served as Toyota car launch of the effort to a new generation of cars ‘green’ aimed at reducing air pollution increasing fuel efficiency. Toyota initially fore-casted that the offspring will account for a third of the auto market in the world as far back as 2005. The NHW10 Prius styling from California designers, selected over competing designs from other Toyota design studios.
Toyota Prius (XW10) Export Model
The 2001-2003 model year Toyota Prius for the market in the United States (NHW11) was powered by a 1.5 liter Atkinson cycle 4 cylinder petrol engine, permanent magnet AC electric motor, and 274-volt nickel hydride metal (Ni-MH) battery pack. Improved engine fuel 70 hp (52 kW) and 82 ft · lbf (111 N · m) of torque. The electric motor generated a maximum of 44 hp (33 kW) and 258 ft · lbf (350 N · m) of torque. The NHW11 Prius became more powerful in part to satisfy the high speed and long distances that North Americans drive. Air conditioning was standard equipment.
The car was the second mass-produced hybrid on the American market, after the two-seat Honda Insight. Although the Prius five years, its battery pack to prevent the cargo space. The interior of the vehicle featured a dash-mounted shift lever, and a small touch screen hybrid powertrain display. This feature is demonstrated operation of the vehicle about the interplay between gasoline engine, battery pack, and electric motors, and may show a bar graph fuel economy results.
In the United States, the NHW11 was the first Prius sold. The Toyota Prius was marketed between Echo and Corolla small conventions. The published price of the car was $ 19,995. The California Air Resources Board (Carb) vehicle is classified as Ultra Low Emission Vehicle (Lev). At one point, Toyota Prius owners were entitled to a tax deduction US $ 2,000 from their gross income. Unlike before NHW10 model, Toyota executives said the company broke even financially sales of the NHW11 Prius.
European sales began in September 2000. The official launch of Toyota Prius in Australia occurred in 2001 after the 2001 Sydney Motor Show, although sales were slow until the model NHW20. In 2006, Toyota recalled about 8,500 2001 and 2002 model year Toyota Prius vehicles because of incorrectly manufactured Crankshaft position sensor.
In 2009, after being investigated by the California Air Resources Board, Toyota extended nation-wide campaign to owners MY 2001-2003 Toyota Prius for the initial problems resulting from the wrong body led to the electronic throttle control module malfunction.
