The redesigned 2003 Toyota Prius (XW20 generation) shifted into a higher vehicle segment thanks to an expanded wheelbase and larger dimensions, while retaining a compact exterior footprint. The futuristic body design was further optimized for improved aerodynamics, delivering enhanced output and efficiency for both the internal combustion engine (ICE) and the hybrid powertrain.
This information applies to 2003–2009 Toyota Prius Gen 2 (chassis code NHW20; MC platform) models equipped with the 1.5 L 1NZ-FXE gasoline hybrid powertrain.
