1992 Mitsubishi Lancer Evolution I RS (Japan)

Mitsubishi Lancer Evolution I RS is documented here as a Japanese factory grade, with its own equipment reference and a carefully scoped rarity record. The original RS addresses the competition-oriented side of the first Evolution programme. A sparse cabin is only one visible part of that identity. A genuine RS may later receive road equipment, just as a GSR may be stripped for motorsport. Preserve the original grade in the record and describe the present configuration separately.

Where this grade fits

The first Evolution put Mitsubishi’s turbocharged four-wheel-drive formula into a compact Lancer sedan. Its importance is the relationship between a recognisable road car and a competition programme: the body, cooling arrangements and driveline belonged to a development path that could be homologated for rallying. The October 1992 launch therefore marks the beginning of a specific model family, rather than the first turbocharged Mitsubishi or the first four-wheel-drive Lancer of any description.

Engine, transmission and equipment

The Japanese catalogue identifies the 4G63 intercooled turbo engine, a five-speed manual and full-time four-wheel drive. That combination is the useful starting point for understanding both grades. The GSR and RS share a generation, but their equipment choices serve different purposes. A later engine conversion can reproduce a power figure without reproducing the original car’s model identity, driveline specification or body history.

Design and identification

The narrow sedan body makes the first Evolution visually restrained beside the later widebody cars. Its substantial rear spoiler and open front bumper provide more useful clues than a generic Evolution badge. Examine the complete front and rear treatment together. On a surviving car, wheels, exhausts and seats can have changed several times, so an apparently convincing exterior should begin an identification exercise rather than end it.

How many are recorded?

1,817 Japanese-market RS records in the cited ASA/CAPS-derived dataset. This is a catalogue record count, not an independently audited completed-production total, a manufacturer-announced cap or a worldwide survivor census. The grade is kept separate from other specifications within the same generation. Do not add a market record count to a previously quoted generation total without reconciling their coverage. The original workbook figure is preserved in the evidence register, with any difference explained rather than silently substituted.

Documentation for an individual car

Begin with the full chassis and model information, then match it to the relevant dated Japanese brochure. Retain original documents and a chronological account of major changes. A short chassis prefix can be shared by multiple grades or generations, so it should not stand alone as proof. For a competition-prepared car, add the preparation and event history as a separate layer of provenance. A competition logbook records a use history; it does not automatically authenticate every claim about the original road specification.

Understanding originality and modifications

For a useful comparison, separate three questions: what the factory offered, what this particular vehicle was originally built as, and what survives on it now. The brochure answers the first. Original model information and contemporary records help answer the second. Inspection and recent photographs answer the third. Disagreements between those sources can reveal modifications or repairs, but they need to be documented rather than resolved by choosing the most attractive specification.

Frequently asked questions

Is the rarity figure a worldwide production total?

1,817 Japanese-market RS records in the cited ASA/CAPS-derived dataset. This is a catalogue record count, not an independently audited completed-production total, a manufacturer-announced cap or a worldwide survivor census.

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.
