About Toyota Prius
The NHW20 Prius was a complete redesign for the 2004 US model year. It was unveiled during the April 2003 New York International Auto Show. It was restyled as a compact liftback, fitting between the Corolla and Camry, with reorganized mechanical and interior space greatly boosting rear-seat legroom and baggage space. According to the EPA, the second-generation Prius is more ecologically friendly than the previous model and is 6 inches (150 mm) longer. Its more aerodynamic Kammback body strikes a balance between length and resistance to the wind, resulting in a drag coefficient of Cd=0.26. The development effort, led by principal engineer Shigeyuki Hori, resulted in the vehicle receiving 530 patents.
Production began in August 2003 at the Tsutsumi facility in Toyota, Aichi, and was expanded to the Fujimatsu plant in Kariya, Aichi, in October 2004.
The Prius is the first vehicle in the industry to use an all-electric A/C compressor for cooling. The XW20 is more powerful and efficient than the XW10 when combined with a smaller and lighter NiMH battery. In the United States, the battery pack on 2004 and later vehicles is warranted for 150,000 miles (240,000 kilometers) or 10 years in states that have implemented California’s higher pollution control requirements, and 100,000 miles (160,000 kilometers) or 8 years in other states. The hybrid components are warranted for 100,000 miles (160,000 kilometers) or eight years.
It is designated as a SULEV (Super Ultra Low Emissions Vehicle) and is approved as a “Advanced Technology Partial Zero Emission Vehicle” by the California Air Resources Board (AT-PZEV).
