Porsche 911 GT3 Cup (992)

Scope of this guide

This guide is scoped to the Porsche 911 GT3 Cup of the type 992 generation, the one-make race car that Porsche Motorsport revealed in December 2020 and delivered to teams from February 2021 for the Porsche Mobil 1 Supercup and the national Carrera Cups. It is a rear-engine, rear-wheel drive, two-door coupe race car with a 4.0L naturally aspirated flat-six petrol engine. It is not a guide to the road-going 911 GT3 (992), which is a different car with different figures, not a guide to the earlier 991 GT3 Cup, and not a guide to the 992.2-based 911 Cup that Porsche announced in July 2025 for the 2026 season. Adverts for all of these carry similar names, so check the car you are looking at.

We have not driven this model for this article. Everything here comes from three cited sources: Porsche's own newsroom release of 12 December 2020, PistonHeads' report on the launch, and the government recall checker. We also read Porsche's July 2025 release on the successor car, an ultimatecarpage.com entry and a simracing.wiki page, and we say where a figure rests on them. This is a race car, so we have not invented any road-car ownership experience, running costs or parts prices. Where a figure is missing we say so.

The figures at a glance

• Engine: 4.0L naturally aspirated flat-six petrol, water-cooled with dry-sump lubrication, mounted behind the rear axle. Porsche's release calls it a four-litre engine and gives no cubic capacity. Our catalogue stores 3996 cc, a figure that other sites print but that Porsche's release does not, so treat it as the usual road-engine capacity rather than a Porsche Motorsport statement.
• Power: 503 bhp. Porsche prints 375 kW (510 hp) at 8,400 rpm, and the redline is 8,750 rpm. The English "hp" in Porsche's release is the metric horsepower, which is the same as PS, so we convert it ourselves: 510 PS multiplied by 0.98632 is about 503 bhp, and 375 kW multiplied by 1.341 is also about 503 bhp.
• Torque: 470 Nm at 6,150 rpm, printed by Porsche. Porsche does not print a figure in pound-feet.
• 0-100 km/h: no figure shown. Porsche's release does not give one, PistonHeads does not give one, and we found no manufacturer or press source that does. Our catalogue previously held 3.4 seconds, the figure quoted for the road-going 992 GT3, which is a different car.
• Top speed: no figure shown. Porsche does not publish one in the sources we read, and a race car's top speed depends on the gearing chosen for each circuit.
• Drive: rear-wheel drive, with the engine in the rear. Porsche's release mentions the rear-axle drive shafts but never says rear-wheel drive in so many words, so the layout is our reading of the car and of the 911 design, not a quoted statement.
• Weight: about 1,260 kg dry, which Porsche says is about 35 kg more than the previous Cup car, partly because extra struts were added to the steel safety cell.

What Porsche says about the car

Porsche's release describes the 992 Cup as the first racing version based on the current 992 generation, and the first Cup car with the wide turbo-style body. The six-speed sequential dog-type gearbox weighs about 72 kg, is changed by paddles and uses an electric servo actuator instead of the earlier pneumatic one. The clutch is a three-plate sintered-metal racing unit with a single-mass flywheel. Rims are 12 inches wide at the front and 13 inches at the rear, with track widths of 1,920 mm at the front and 1,902 mm at the rear. Brake balance can be adjusted from the cockpit, and special calipers allow quicker pad changes. ABS is optional, activated by a digital code, and is switched off in the Supercup and most Carrera Cup series.

The shell is a steel safety cell with an escape hatch in the roof that meets the latest FIA requirements, polycarbonate windows, carbon-fibre doors, bonnet and rear wing, and an aluminium front lid. The car can run on synthetic fuels, which Porsche says lowers carbon dioxide emissions in racing use, and the company expected lap times to fall by about one per cent depending on the circuit.

What PistonHeads adds

PistonHeads reported the car on 13 December 2020 under the title "Porsche unveils new 911 GT3 Cup", by Matt Bird. It repeats 510 hp at 8,400 rpm, but says that is up 35 hp and 900 rpm on the 991 car, while Porsche's own release says 25 hp. We have not settled the difference, and the 25 hp figure is the manufacturer's. PistonHeads also reports double wishbones at the front in place of the earlier MacPherson struts, electro-mechanical steering in place of hydraulic, a swan-neck rear wing, a changed steel and aluminium split in the body, and the data logger and control units moved out of the passenger footwell so that a second occupant fits. It gives a launch price of 225,000 euros plus local taxes and says the car was on sale to race teams immediately, reaching customers in February as an ex-works car with a complete accessory kit. That is a launch price in history, not a market value, and we have not found a used price source we trust.

How many were built

Porsche's July 2025 release on the successor says the model that debuted in 2021 has been produced 1,130 times. The same release says the figure of 5,381 covers all the 911-based one-make cup cars, so do not read it as a 992 count. We have not seen a split by year, by market or by evolution kit, so we cannot say how many cars were updated during the production run. We store 2021 as the start year and leave the end year open, because the manufacturer pages we read do not give a date on which production of this car ended, only that a new 911 Cup is used from the 2026 season.

Is it road legal

We found no source that describes this car as road legal, and Porsche's release does not mention road use or road equipment. It describes it only as a racing vehicle for one-make series, sold to teams. We therefore treat it as a track-only car, which matches the category our catalogue stores. The sensible reading is that you buy it for circuit use, through Porsche Motorsport or a team that is selling a car. If someone offers one registered for the road, ask for the paperwork and the conversion details, and take advice from a specialist. We are not giving a legal opinion.

What to check before buying

• Ask exactly which car it is: the 992 GT3 Cup of 2021 or later, a later update, or the 992.2-based 911 Cup. Ask for the chassis number and the Porsche Motorsport history.
• Ask for the service record from the team or a Porsche-approved workshop, and for the engine and gearbox hours. We found no published service interval or rebuild cost, so any figure you are given is an estimate.
• Have the steel safety cell and roof escape hatch inspected for damage or repair, and check that the extinguisher system and seat and harness dates are current for the series you intend to race in.
• Check which ABS and brake-balance settings and which wheels and tyres come with the car, given the 12 inch and 13 inch rim widths.
• Check the carbon doors, bonnet and rear wing for cracks and repairs, and the splitter and diffuser for track damage.
• Ask what the previous owner used it for. A car that has run a full Supercup season is different from one that has done a few track days.
• Get an inspection from someone who knows the Cup cars, since a general garage will not.

Recalls and the government check

The government vehicle recall checker, at gov.uk, is built for road vehicles. Its page says the MOT checking service shows outstanding safety recalls for a vehicle with a registration, that the vehicle recalls checker takes the make, model and year, and that non-safety recalls come from the manufacturer directly. We did not run it, because we are not looking at a specific car, and we did not read the live page for this article, so re-check that wording yourself. A track-only race car that has never been registered may well not appear on it at all, and we found no recall notice for the Cup in any source we read. Absence from our sources is not a clean bill of health. Ask Porsche Motorsport whether any technical bulletin or recall applies to the chassis number.

About the photograph

The picture at the top of this page shows a Carrera Cup Great Britain car in team livery, photographed at the SCD Secret Meet in June 2024 according to its Commons description. It is a customer car, so the colours and sponsors are not standard. The photograph was cropped and resized, and no person or readable number plate appears in it. The windscreen carries a driver's name as part of the livery.

Verdict

The Porsche 911 GT3 Cup (type 992) is a 503 bhp, 470 Nm, rear-engine, rear-wheel drive track car of about 1,260 kg, built in a run of 1,130 and sold new at about 225,000 euros plus taxes. The figures that Porsche itself publishes are solid. Porsche gives no 0-100 km/h or top speed value, so we show none. If you are shopping for one, confirm which version it is, ask for the full competition history, and have it inspected by a Cup specialist. We have not driven it, so use the sources and a proper inspection to decide.
