2021 Porsche 718 Cayman GT4 RS — Road Model

The Porsche 718 Cayman GT4 RS made its public debut at Los Angeles in November 2021, before the 2022 reference used in the inventory. Its four-litre naturally aspirated flat-six, seven-speed PDK and distinctive intake openings gave the 982 Cayman a separate RS identity. Porsche stated 368 kW or 500 PS. The programme was not announced as a numbered edition, so this profile does not invent a numerical cap or present the optional Weissach package as an additional production series.

A 2021 premiere before the 2022 road-car period

The factory announcement establishes the GT4 RS’s November 2021 Los Angeles debut and describes the new road model. This record uses that introduction year while preserving the inventory’s original 2022 reference in its metadata. The difference is chronological rather than a separate edition. A car photographed or registered in 2022 remains part of the same road programme, while the separately introduced Clubsport is a competition vehicle with its own specification and intended use.

Four litres, high engine speed and seven-speed PDK

Porsche’s international release gives 368 kW or 500 PS from a four-litre naturally aspirated flat-six and identifies an engine-speed capability up to 9,000 rpm. The road model uses seven-speed PDK. These references must not be replaced with the original 981 GT4’s 3.8-litre manual specification or the earlier six-speed Clubsport gearbox. An individual car’s mechanical condition, tuning and component originality remain separate questions from the factory model’s launch description.

Intakes where the rear side windows would be

The process-air intakes behind the occupants are among the most recognisable features. Porsche explains that they occupy the space normally used by the Cayman’s small rear side windows, while the lower side openings continue to serve engine cooling. This arrangement links visible body design with the intake system. Editorially, it makes the RS identity legible without needing a badge, but a photograph still cannot authenticate the underlying chassis or establish whether all original components remain installed.

Lightweight construction and the RS body package

The manufacturer describes CFRP front body components, reduced insulation, lightweight glass and a swan-neck rear-wing arrangement. Its stated DIN reference is 1,415 kg with fuel and no driver. Preserve that measurement basis instead of treating the number as a universal present-day weighing. The optional Weissach package adds a particular equipment specification within the model. It does not, on the retrieved evidence, create a second numbered allocation or a completed-production count independent of the GT4 RS programme.

A finite model, with no fabricated numerical scarcity

The inventory specifically includes discrete unnumbered Motorsport derivatives. The retrieved launch source establishes this RS model but supplies no numerical cap used here, so numerical production fields remain empty. Do not describe the car as one of a fixed worldwide run without stronger evidence. Establish a particular example through chassis and build records, then date changes to wheels, exhaust, suspension or bodywork. The selected photograph illustrates a catalogued road GT4 RS and is not a new inspection or chassis census.

Specifications and identity reference

Rarity and production scope

Verified discrete 718 Cayman GT4 RS road programme, included under the inventory’s finite Motorsport-model scope. The factory premiere was in 2021; the original 2022 reference is preserved separately. No numbered cap or independently audited completed total is assigned; Clubsport and equipment-package counts are separate.

What the photograph represents

A car catalogued as a 2022 718 Cayman GT4 RS. It illustrates the road programme unveiled in 2021, with no claim to authenticate its present engine, original equipment or an exact production total.

Frequently asked questions

Was the road GT4 RS manual only?

No. Porsche specifies seven-speed PDK.

Is the Weissach package another numbered production run?

No separate numerical allocation is established by the cited launch source.

What is the production-count boundary for this profile?

Verified discrete 718 Cayman GT4 RS road programme, included under the inventory’s finite Motorsport-model scope. The factory premiere was in 2021; the original 2022 reference is preserved separately.
