RUF CR
A naturally aspirated RUF conversion based on a 1979 911 SC is examined as a distinct RUF product rather than a visual copy of the turbocharged CTR.

01
What the issue covers
Original, page-referenced summaries; magazine photography and authored prose are excluded.
Page 32
Rally-prepared 356 B
A restored 1962 356 B demonstrates how rally equipment, mechanical preparation and known non-originality can form a coherent, usable historic car.
Page 42
E&R Classics profile
A large Dutch classic-car retailer is documented as a July 2025 commercial source; stock descriptions and preparation claims still require current verification.
Page 50
Three-litre 911 Turbo restoration
A Minerva Blue early 930 anchors a model-history and restoration story focused on the first production 911 Turbo's engineering and preservation.
Page 58
Lohner-Porsche Mixte
The restoration of an early petrol-electric Lohner-Porsche illustrates Ferdinand Porsche's use of wheel-hub motors and a combustion engine driving a generator.
Page 66
CSF 911 SC restomod
A comprehensively rebuilt 911 SC combines a larger naturally aspirated engine, modernised chassis and bespoke interior. Performance figures remain builder claims.
Page 74
914 ownership in a wet climate
A modified 914 provides practical evidence about rust, water paths, fuel systems, parts interchange and the value of specialist knowledge.
Page 82
Modified 993 Carrera
A 993 Carrera profile considers suspension, wheels, cabin changes and VarioRam-era context without presenting modifications as universally suitable.
Page 90
Modified 964 Turbo
A road test places an upgraded 964 Turbo against the standard model's chassis and turbocharged character, while treating output as a period claim.
Page 100
Porsche and the Schwimmwagen
A historical article covers Porsche's wartime work on amphibious Volkswagen-derived vehicles. It is retained as historical context, not celebratory brand material.
02
Technical notes worth retaining
These notes aid research and inspection planning; they are not workshop procedures.
From page 8
RUF CR identification
- The featured CR is presented as a RUF-built naturally aspirated car derived from a Carrera-era 911, not as a factory Porsche CTR.
- Body, engine, wheel and interior details need documentation because appearance alone cannot establish RUF provenance.
- The magazine's output and speed figures are period claims and should not substitute for chassis records or a current inspection.
From page 58
Lohner-Porsche Mixte architecture
- Electric motors at the wheel hubs provided propulsion while a combustion engine and generator extended operating range.
- The layout anticipated elements of a series-hybrid architecture but used the materials, controls and battery technology of its own era.
- Surviving examples are historical artefacts; the article is not evidence for modern high-voltage service procedures.
From page 74
914 inspection priorities
- Rust and water ingress around the battery area, structural sections, sills, floors and removable-roof drainage paths can dominate purchase risk.
- Ageing fuel hoses and routing deserve urgent inspection because the engine sits behind the occupants.
- Suspension bushes, brakes, electrical condition and evidence of old collision or cosmetic repairs should be assessed together.
From page 82
993 modification evidence
- Wheel, tyre and suspension changes alter geometry and compliance, so invoices and alignment records matter.
- VarioRam and non-VarioRam cars should be identified by model year and engine evidence rather than assumed from exterior appearance.
- A reversible, documented modification is easier to evaluate than an undocumented collection of parts.
03
Buyer and ownership notes
Cross-cutting lessons retained without turning one featured car into universal advice.
- RUF identity must be established with documentation; visual resemblance and seller terminology are insufficient.
- On a 356, 914 or early 911, structural condition can outweigh engine specification or cosmetic finish.
- The advertiser index is a July 2025 lead register, not proof that every listed business still trades or supplies the same products.
