The 2003 facelift, designated the CH series, introduced a heavily updated VR-X, which included new 16″ alloys, stiffer suspension, body styling kit, and gear shifter borrowed from the Lancer Evolution. In 2004, the new Lancer wagon was introduced as a direct replacement for its ageing predecessor.

In August 2005, all Lancers were upgraded to the 2.4 L 4G69 engine, producing 115 kW (154 hp) and 220 N·m (162 lb·ft) of torque. The upgraded engine also saw a change in trim levels and upgraded equipment—the ES and LS models now featured a more upmarket looking black interior, while the VR-X gained a new black grille to closer resemble the Lancer Evolution IX. The equipment levels of all models were also upgraded, with the LS and VR-X gaining climate control, and a premium audio system sourced from the luxury Mitsubishi Verada. The Exceed model was discontinued, and all updated models now used JDM sized rear bumpers instead of the larger USDM sized versions. Additionally, the wagon also saw these changes; and as of 2007, continues to be sold alongside the sedan.

The ES and LS models were given a minor facelift for the 2007 model year; this time gaining the same front grille as the US models, and putting it into line with the current corporate look—similar to that of the Colt and the locally built 380. Prior to the introduction of the all-new ninth generation Lancer, a limited edition ES model dubbed ‘Velocity’ went on sale. This package included VR-X grill, rear spoiler, leather/alcantara bolsted seats, sports pedals, 15″ OZ alloy wheels and chrome exhaust tip—all for the same price as the previous standard ES.
