Introduced in 2003 for the 2004 model year, this was when Prius sales finally began to kick in. It had been redesigned into a mid-size Kammback sedan, in which it had became more aerodynamic with a drag coefficient of 0.26 thanks to the balance of length and wind resistance. Warranty was longer in states that have adopted the stricter California Emissions Standards; it was 150,000 miles or 10 years versus 100,000 miles or 8 years elsewhere. An industry first involving this car was that it cooled itself with an electric A/C compressor. Approximately 1,192,000 units were sold worldwide.
