1991 Mercedes-Benz C 112

The Mercedes-Benz C 112 used the form of a mid-engined supercar to explore active safety and vehicle control. It appeared at Frankfurt in 1991 and survives in documented physical-exhibit records. Its importance is best understood as a research programme, rather than a promised customer series that a production total can describe.

History and verified programme identity

The Petersen Automotive Museum identifies the C 112 as a 1991 experimental prototype and places its debut at the Frankfurt motor show. Mercedes-Benz presents it as a technology carrier for active safety systems. Those descriptions are more useful than a generic claim that the car was simply cancelled. They explain why the design could have a dramatic body, a substantial engine and a full physical presence while still belonging to an experimental rather than customer-production category.

Engineering and design

The museum specification identifies a six-litre V12, while the physical car’s low nose, side intakes and rear engine position express a different layout from Mercedes-Benz’s front-engined sports cars. The central engineering question concerns how vehicle behaviour can be controlled, not just how much power fits behind the occupants. An experimental car may combine mature components with systems still being investigated. A published concept specification should therefore remain attached to its original source and should not be treated as a new measurement of every later display appearance. This specification belongs to the documented programme. It should be compared using the original measurement convention and the relevant configuration. A larger number copied from a different engine, market or racing derivative would describe a different car. Likewise, an engine change during restoration does not add another vehicle to the original production run. The distinction matters particularly when a model name appears in both road and competition histories: shared styling or ancestry can coexist with substantially different structures and equipment.

What makes this version distinct

C 112 is distinct from the earlier C 111 family, despite the similar research-car naming pattern and upward-opening doors. It is also separate from the Sauber-built racing cars that help explain the period context. A physical prototype confirms that a design reached full scale; it does not establish customer homologation, a completed sales programme or an independently tested road-performance record.

Collecting and chassis evidence

A strong C 112 archive should preserve original research descriptions, contemporary display photographs and later custodial records. Date the equipment claims carefully. A current exterior photograph cannot demonstrate the operating state of an active system, and a display placard is not a substitute for a documented engineering test. Start with the permanent chassis identity and a dated factory specification, then organise invoices, registration documents and photographs into a chronology. A recent photograph describes present appearance; the original delivery record establishes how the vehicle left its manufacturer. Record replacements and reversible changes without erasing their dates. For a limited edition, retain the allocation paperwork and edition plate together, since a badge alone cannot establish membership. Photographs of body seams, interior fittings and mechanical markings help a specialist understand changes across time. Where a vehicle has been repainted or restored, keep the earlier material alongside the finished appearance. A clearly documented change is more informative than an unsupported claim that every component has remained untouched.

Related Mercedes-Benz designs and meaningful comparisons

F 200 Imagination shifts the research emphasis toward electronic interfaces and control. The CLK-GTR road coupé later connects extreme sports-car form with an actual low-volume customer programme. These comparisons clarify the different paths a dramatic Mercedes-Benz show car can take.

Reading the sources

The programme sources and the photograph answer different questions. Manufacturer and custodial records establish the original model, Type, category and published production scope. The creator’s file establishes the pictured subject, setting and image permission. An individual chassis history can then add ownership, competition entries and dated repairs without changing the scope of the original programme. Build references are not survivor counts, and a later specification does not automatically become an additional newly manufactured vehicle. Where primary evidence does not establish a complete fabrication census, that field remains unassigned.

Specifications and rarity evidence

Frequently asked questions

How rare is the C 112?

Verified physical 1991 experimental prototype. The inventory’s one-car claim is not used as an independently reconciled fabrication census. No customer series, road allocation or current survivor count is assigned.

How is C 112 classified?

This is a physical Mercedes-Benz concept programme, separate from road production. Proposed equipment and production plans are distinguished from documented physical exhibits and verified operating hardware.

Which technical details are established for the programme?

The primary record supports debut: Frankfurt motor show, 1991; layout: Mid-engined experimental sports car; engine reference: Six-litre V12, custodial museum specification. These are programme or explicitly attributed photo references. A particular surviving car’s engine, chassis repairs and competition preparation require its own dated documentation.

Does the photographed appearance establish factory originality?

The caption records a real creator-identified C 112 subject and its documented setting. It establishes the illustration’s scope, while original components, restoration work and individual race provenance require chassis-specific evidence. A competition number, current paint or museum display is not used as an originality certificate.

What rarity or archive scope is verified?

Verified physical 1991 experimental prototype. The inventory’s one-car claim is not used as an independently reconciled fabrication census. No customer series, road allocation or current survivor count is assigned.
