It has been announced that the latest 992.2 Porsche 911 one-make cup race car will finally debut in the summer of 2025.
This cup car is based on the current 911 (992.2) generation and is a model that has been thoroughly optimized for racing, with the development phase already nearly complete.
The new cup car, which will be unveiled this summer (which means soon!), will be used in the Porsche Mobil 1 Supercup and some Carrera Cup series from the start of the 2026 season.
Currently, one-make races using the 911 Cup car are held in more than 12 countries around the world, including Japan, and there are also 23 Porsche-approved sprint and endurance challenges and trophies in which the GT3 Cup car is also used.
For this reason, the 911-based one-make cup car, with 5,381 units built to date, is said to be one of the most produced racing cars in the world.
By the way, where will this GT3 Cup car be made? It will be produced at the Stuttgart factory, just like the regular 911 series, and 1,130 units of the current model that debuted in the 2021 season have already been produced.
What's even more surprising is that the production time for this 992.1 generation 911 GT3 Cup, I believe in assembly, is just under eight hours.
Indeed, when I ordered a 911, I tracked the production status of the car and it was completed in just a few days, so I thought, "That's faster than I expected, it's amazing," but the Cup Car is a race car, so it's "fast" after all (lol)? The production time is even faster, just under 8 hours!
Dynamic Development Phase
Development of the new GT3 Cup will begin at Porsche Motorsport in Weissach in January 2024.
Like its predecessor, the Cup Car will combine mass production technology with high-level motorsport characteristics to transform it into a more pure-bred racing car than ever before.
Particular focus during development was placed on improving the aerodynamics of the front end, which has a positive effect on drivability.
There are also numerous improvements to safety, electronics, brakes, power transmission, flat-six engine and handling.
The tire partner this time will once again be Michelin.
And in what feels like an even more cutting-edge development than ever before, the new 911 GT3 Cup has been powered exclusively with the eFuel blend used in the Porsche Mobil 1 Supercup (PMSC), including for all test bench runs.
Actual test runs were carried out on the Italian Grand Prix Circuit in Monza, the Lausitzring in Brandenburg, and on the in-car circuit at the Weissach Development Centre.
During development, the car was driven by two former Porsche junior drivers, Bastian Buus and Klaus Bachler.
Others present included racers Laurin Heinrich and Marco Seefried.
Testing program using Super Cup eFuel blend
The eFuel blend to be used in the 2025 Porsche Mobil 1 Supercup technically meets the International Automobile Federation's (FIA) new Appendix J requirements for renewable (“Advanced Sustainable”) fuels, with all combined CO2 reduction measures* representing a total CO2 equivalent savings of 661 TP1T compared to a fossil fuel equivalent.
This performance-specific racing fuel blend contains 79.71 TP1T renewable content by volume.
The majority of the blend will be made from a renewable synthetic feedstock known as MtG (methanol synthetic gasoline), with other blend components including renewable, waste-based or residue-based ethanol, which will be used to increase the fuel's oxygen content, octane rating and other properties.
The octane number is 100.5RON (Research Octane Number). I don't understand this, but it seems to be a little higher than the number of high-octane fuels in Japan.
This racing fuel blend has been specially developed for boxer engines used in motor racing, combining high performance with the highest possible proportion of renewable blend components.
So, the newly developed 992.2 Cup car is due to be unveiled this summer, but based on the information provided so far, does this mean that the next Cup car will only be able to use the same synthetic fuel blend that Porsche has been testing with?
Based on the published statement, it appears that development testing is being done with a racing fuel blend, so it doesn't seem like they're saying "No, high-octane fuel is OK," but what do you think?
If we could only use blended fuel, we would have to prepare that fuel (outside of the normal process) when we raced in the Carrera Cup in Japan, and I was worried that this would raise many hurdles.
I guess I'll just wait for the official announcement.
(※)HIF, the manufacturer of the raw fuel used for the racing fuel blend, is taking several measures at its Haru Oni pilot plant in Chile to keep CO₂ emissions from production as low as possible. Among other things, the electricity required for grid connection and control room stabilization is sourced exclusively from renewable wind energy. At the same time, CO₂ emissions from transport are offset by CO₂ certificates from South American renewable energy plants for the provision of biogenic CO₂ for eFuel synthesis. This means that, as far as possible, all elements in the supply chain can demonstrate a reduction in CO₂ emissions. HIF has set itself the goal of obtaining the CO₂ required for the synthesis process from a direct air capturing (DAC) plant in the future. Development is being driven forward in collaboration with partners. To minimize the need for grid stabilization, HIF is also integrating a dynamic battery storage system to act as an energy buffer. This will enable HIF to transfer important findings from the pilot plant to potential series production plants.
