Subaru introduced the “New Age” Impreza in 2000. Larger in size compared to the previous iteration, the sedan increased its width by 40 millimetres (1.6 in), while the hatchback increased by just 5 millimetres (0.2 in).
Turbocharged versions of the 2.0 and 2.5-liter engines were offered in the WRX and WRX STI models. STI models featured a more powerful 2.0-liter (2.5-liter outside of the Japanese market) turbocharged engine. WRX models featured a 2.0-liter turbocharged boxer engine until 2005, after which they switched to the 2.5-liter turbocharged engine.
Subaru manufactured a badge engineered variant, marketed by Saab as the 9-2x for the North American market in solely the wagon bodystyle. Nicknamed “Saabaru”, the 9-2X received redesigned front and rear styling as well as other interior, acoustic and technical modifications.
