R / production rarity

How rare is it?

A simple 1–5 rating based on completed worldwide production for this exact version. Price and desirability are not included.

A reliable worldwide figure is not listed in the references.

How the rating works

The rating uses five fixed production bands. Smaller production runs receive higher ratings. Exact totals and responsibly sourced estimates for this precise version can be rated. Plans, regional totals, lower bounds, disputed figures and broader-family totals remain visible but unclassified. The evidence description is kept separate from the rating so a source limitation cannot change how scarcity is measured.

What creates the sound

Mechanical, induction, transmission and exhaust sound should be documented separately where practical.

A factory-stock claim requires evidence for engine, intake, catalysts, gearbox and silencers.

Open-licence recordings with incomplete configuration evidence may publish only as Unregistered.

History and character

Origins and context

CLK GTR Straßenversion (C297) records one precise Mercedes-Benz performance-car configuration from 1998–1999. The CLK GTR Straßenversion is the road homologation counterpart to Mercedes-Benz and AMG’s 1997 FIA GT programme.

At its centre is a 6,898 cc naturally aspirated v12 identified as M 297. Mercedes-Benz publishes 450 kW (612 PS) for this scope and 775 Nm. A road-specific V12 and homologation cabin translated the purpose-built FIA GT racer into a small road series.

The engine sits in a longitudinal rear-mid engine, rear-wheel drive layout and works through a 6-speed sequential manual.

This entry belongs to a deliberately narrow Mercedes-Benz chronology. Related badges, body styles and competition derivatives can share a visual or mechanical vocabulary without sharing exact specifications. The family tree supplies context, not permission to transfer a recording or fact from a neighbouring model.

Engineering and character

The listening cues large-capacity V12, sequential transmission, rear-mid engine, homologation exhaust are orientation rather than proof. A cold start can expose idle control and mechanical texture; acceleration can document induction, combustion and shift behaviour; a fly-by can place exhaust and tyre sound in an exterior context.

The focus here is the C297 CLK GTR road coupé. It excludes the CLK-GTR race cars, roadsters, CLR and replicas. Many survivors have replacement exhausts, engine work or other changes. An openly licensed recording may still be useful when its exact state is uncertain, but the page will show a visible Unregistered note until evidence resolves the match.

It invites cold start, acceleration and fly-by recordings, as well as photographs, documents and corrections.

A photograph identifies the model but does not prove every detail of a surviving car.

Legacy and identity

Exact location and ownership evidence stay private while the technical context remains available to later listeners.

That evidence also helps readers compare like with like. A useful submission therefore describes what was heard and how it was recorded, while avoiding claims that the microphone alone cannot establish. Photographs of permitted mechanical details and contemporary documents can strengthen the record, but personal identifiers and ownership evidence remain private.

Preservation means keeping every claim inspectable and correctable. That structure protects the exact identity on which a meaningful sound archive depends.
