2005 Mitsubishi Lancer Evolution IX RS (Japan)

The Japanese IX RS is a factory competition-oriented base model. It has its own catalogue column and model information; a stripped GSR cannot be authenticated as an RS by appearance alone.

Where the IX RS fits

The CT9A sedan belongs to the established turbocharged, four-wheel-drive Evolution lineage. Within that body family, Mitsubishi supplied different factory grades with different equipment priorities. A grade name is therefore meaningful only when it is attached to the correct generation, date and market. This profile follows the Japanese specification and does not silently merge export-market grades that happen to use familiar Evolution badges.

Engine and transmission reference

The Japanese factory specification pairs a 1,997 cc intercooled turbo 4G63 engine with four-wheel drive. In the IX family, MIVEC is part of the documented engine identity. GSR uses a six-speed manual, while the Japanese IX GT and RS use five speeds. The appropriate brochure column provides the period rating and equipment baseline. Those are factory reference figures; current power, boost control and gearing require separate evidence for an individual car.

Design and grade identification

The familiar sedan silhouette can make different CT9A specifications appear interchangeable in photographs. Record the model information before relying on the wing, wheels, seats or badges. MR-specific construction and suspension claims need documents or inspection appropriate to the car. The included photo caption states whether the image is an identified grade or a family reference, and visible modifications remain part of the photographed example rather than a factory specification claim.

How many are recorded?

195 Japanese-market catalogue records in JDM Catalogues’ independently compiled ASA/CAPS-derived dataset for this factory grade. This is not a manufacturer-announced production cap, an audited completed worldwide production total or a survivor count. The record is kept separate from other factory grades and from the earlier or later MR phase. Adding it to a broader generation figure without reconciling scope would count some cars twice. The number supports this explicitly domestic grade record; it does not establish the quantity supplied to every country.

Documentation for an individual car

For an RS, obtain the complete original model information and the correct dated equipment chart. Competition preparation may replace seats, differentials, body parts and safety equipment. Preserve that preparation history as a second layer of provenance, with event records where available. A competition logbook can document use, but it does not by itself prove that the road-car shell began as the factory RS grade.

What makes this specification worth studying

The Japanese IX RS is a factory competition-oriented base model. It has its own catalogue column and model information; a stripped GSR cannot be authenticated as an RS by appearance alone. Compare the related profiles by transmission, body and factory grade before comparing headline quantities. A smaller recorded group is not automatically a better preserved or more original car. The research value lies in understanding what Mitsubishi offered and how accurately a surviving example retains that configuration.

Frequently asked questions

Is the rarity figure a worldwide production total?

195 Japanese-market catalogue records in JDM Catalogues’ independently compiled ASA/CAPS-derived dataset for this factory grade. This is not a manufacturer-announced production cap, an audited completed worldwide production total or a survivor count.

How should an individual example be authenticated?

Match the complete original model information to the appropriate dated documentation, then record the present condition and modifications separately. A badge, colour scheme or stripped interior alone is insufficient evidence of a factory grade.
