300 SL Roadster

300 SL Roadster (W198 II) records one precise Mercedes-Benz performance-car configuration from 1957–1963. The Roadster reworked the landmark 300 SL into a more usable open sports car while preserving its direct-injected inline-six.

At its centre is a 2,996 cc naturally aspirated inline-6 identified as M 198. Mercedes-Benz publishes 158 kW (215 PS) for this scope. Direct petrol injection and a tubular spaceframe carried the 300 SL concept into a redesigned open body with conventional doors.

The engine sits in a longitudinal front engine, rear-wheel drive layout and works through a 4-speed 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.

The listening cues direct-injected inline-six, four-speed manual, open cockpit, front-engine 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 W198 II 300 SL Roadster. It excludes the Gullwing coupé, later R107 300 SL 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.

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.
