The eighth-generation Mitsubishi Lancer (CY0 and CZ0 body codes), marketed as Lancer X in many countries, debuted at the 2007 North American International Auto Show. Based on the Concept-X design study, it showcased an aggressive front fascia featuring the signature 'Jet Fighter' trapezoidal grille. Built on the global Mitsubishi GS platform co-developed with DaimlerChrysler, the model was offered in four-door sedan and five-door Sportback hatchback forms. Engineering of the Lancer VIII (CY0) (factory code CY0) emphasized high structural rigidity, aerodynamic efficiency, and optimized interior spatial packaging. Built with reinforced body structures utilizing high-tensile steel alloys, the platform delivered reduced curb weight alongside improved occupant crash protection. The vehicle was distributed globally in multiple configuration packages designed to satisfy diverse market demands and regional regulatory specifications.

The petrol engine range comprised 1.5, 1.6, 1.8, and 2.0-liter all-aluminum MIVEC engines, complemented by the AWD Ralliart trim equipped with a 240-horsepower 2.0-liter turbocharged engine. European markets offered a 2.0-liter turbodiesel option. Gearbox selections spanned five-speed manuals, traditional automatics, CVTs, and the Twin Clutch SST dual-clutch transmission on performance models. Global production ended in 2017. The powertrain lineup incorporated efficient engine families paired with robust manual, automatic, or continuously variable transmissions depending on trim selection. Drivetrain engineering integrated advanced suspension tuning and traction management systems.
