Manthey Reveals 30 Anniversary Race Cars Across Porsche 911 and Cayman Models

Manthey celebrates 30 years with a pair of race cars

Manthey has unveiled two limited-edition Porsche competition cars to mark its 30th anniversary: the 911 GT3 Cup MR 30 and the 718 Cayman GT4 RS Clubsport MR 30. Both were presented at the DTM season finale at Hockenheim on 9 October 2026, with production restricted to fifteen examples of each model. The cars celebrate a specialist engineering business whose reputation was built through testing and racing rather than through decorative trim alone.

The launch is directed at track-focused collectors and motorsport customers. These are not conventional road-going special editions intended for daily travel or casual touring. They are developed from competition platforms, and the stated specification reflects the needs of race circuits, support teams and experienced drivers. Anyone considering a purchase will need to account for transport, storage, servicing, tyres and track access as well as the vehicle itself.

A 4.2-litre engine transforms the 911 GT3 Cup

The 911 GT3 Cup MR 30 uses the 992.1-generation Cup racing car as its basis but substitutes a 4.2-litre six-cylinder boxer engine. Manthey lists 412 kilowatts, or 560 metric horsepower, produced at 8,500 rpm, with 500 newton-metres of torque at 6,750 rpm. The powertrain is matched to a six-speed sequential gearbox and rear-wheel drive, maintaining a familiar professional racing arrangement while increasing performance potential.

The engine is only one aspect of the work. Manthey has also revised cooling around a central radiator, increased brake-cooling capacity and adjusted the suspension. Such changes must operate as a coherent package: additional power creates greater heat and loads, while the tyres and aerodynamic configuration affect how consistently a driver can exploit it over a session. The specification should not be translated into a claimed lap-time gain without a comparable independent test.

Carbon bodywork and aero shape the Cup car

The 911 special edition adds carbon front bodywork, a modified bonnet, widened front wings and lighter external components. The aerodynamic package includes an extended rear wing, a new diffuser and revised side details. Together with a wider track and eighteen-inch lightweight wheels, the changes aim to increase the car's ability to maintain grip through fast corners without leaving brake and cooling performance behind.

Manthey cites a suspension configuration with six-way adjustable dampers and springs chosen for the upgraded package. That adjustability makes setup expertise important. A circuit car needs a repeatable baseline for ride height, tyre pressure, suspension settings and aerodynamic balance; extreme settings that work for one layout can make another venue more difficult. The buyer should establish whether suitable trackside engineering support is available.

The Cayman reaches the end of a development line

The 718 Cayman GT4 RS Clubsport MR 30 has a different role within the celebration. It represents the final stage of Manthey's work on Cayman-based competition cars, a line that began with homologation equipment for the earlier 981-generation GT4. The MR 30 retains a four-litre six-cylinder boxer engine delivering 368 kilowatts, or 500 metric horsepower, and a seven-speed PDK dual-clutch transmission.

Rather than increasing displacement, Manthey's focus has been reducing weight, improving aerodynamics and refining the running gear. The specification describes carbon body panels, revised cooling, a high-downforce rear-wing arrangement and lightweight wheels. The model is best seen as a track tool that concentrates years of engineering refinement into a short-run car, not a promise that every driver will find it easier to drive at the limit.

Two different philosophies under a shared anniversary

Although the cars share the MR 30 designation, they reflect different technical starting points. The 911 Cup benefits from a more powerful engine, sequential transmission and extensive changes to the racing chassis. The Cayman emphasizes a lighter, carefully developed final evolution of an existing mid-engined customer-racing platform. Their differing handling characteristics may matter more to a driver than the badge or the production cap.

For a collector who intends to use the cars, choosing between them requires a clear idea of the available circuits and driving programme. Experienced support staff, brake and tyre budgets, engine operating cycles and spare-part supply can substantially influence the real cost of ownership. A bespoke racer may be a compelling acquisition, but it is rarely a practical substitute for a conventional road-legal Porsche GT model.

Design references three decades of Manthey history

Both show cars use a white base with prominent red detailing, a reinterpretation of Manthey's established colours. Their graphics take inspiration from the 911 race car fielded by the company at the Nürburgring 24 Hours, connecting the anniversary cars with Manthey's broader competition history. The Cup version also uses a white-painted chassis as a nod to historic racing Porsches.

Smaller details continue the theme inside the cockpit. Special headrest embroidery, anniversary markings and model-specific finishing identify the limited editions, but the central engineering functions remain visible. The visual treatment is significant to collectors because it documents a particular moment in the manufacturer's history; however, any specification or configuration changes requested by an owner should still be checked against the original technical requirements.

Only thirty cars will be allocated

Manthey will produce fifteen examples of each model, giving a combined run of thirty cars. The company says purchase enquiries will be accepted until 30 October 2026, after which it will decide how the cars are allocated. Deliveries of the Cayman are scheduled to start in November 2026, while the first 911 GT3 Cup MR 30 cars are planned for the first quarter of 2027.

A limit on production does not, by itself, establish a future investment return or even guarantee that a buyer will receive an allocation. Prospective customers should ask about the final technical specification, deposit arrangements, delivery location, customs treatment, track compliance and what Manthey will provide during the ownership period. For a competition-only car, the documents governing parts, support and permitted use deserve the same attention as appearance.

Why this launch matters beyond the anniversary

Manthey operates at the intersection of Porsche motorsport, engineering development and customer racing. The anniversary models illustrate how a specialist company can extend a proven platform through aerodynamic work, cooling, materials and track testing rather than starting a new production car from scratch. Manthey says the ideas were developed to meet real motorsport requirements, with the anniversary creating an opportunity to offer the work in limited series.

For affluent enthusiasts, the two MR 30 cars offer something distinct from a numbered road-car edition: access to a specific competition engineering programme. Their long-term significance will rest on build quality, track performance, support and provenance rather than scarcity alone. The confirmed 2026 news is the debut of two carefully specified customer race cars, with fifteen of each available for allocation.
