  • F1 Sprint format changed

    F1 Sprint will return for a fourth season this year and a format tweak is set to make the spectacle more engaging than ever.

    As confirmed in December, Brazil will host its fourth consecutive Sprint weekend, with Austria to stage its third, Austin and Qatar return for a second year, and China and Miami joining the line-up for the very first time.

    The F1 Commission met to discuss a range of matters and, shorting after the gathering concluded, the Sprint format update was communicated.

    For this year, the Sprint Shootout will move from Saturday to Friday, following an initial free practice session for track acclimatisation and set-up work.

    The 100km Sprint will then take place on Saturday, ahead of qualifying for the Grand Prix later that day. With the Grand Prix itself sticking to Sunday.

    The regulatory refinements for these changes will be presented to the World Motor Sport Council (WMSC) on February 28th.

    Away from the Sprint, a proposal to increase the power unit allocation to four per driver for the 2024 and 2025 season was agreed.
    Additionally, DRS activation for the race will be anticipated to one lap as opposed to two laps after the start of the race, or the re-start following a Safety Car.

  • Audi to join F1 in 2026

    German manufacturer, Audi will be joining the Formula 1 World Championship from the 2026 season as a power unit supplier.

    The announcement comes after new power unit regulations, designed specifically to make it possible and attractive for newcomers to join the sport at a competitive level, were published earlier this month.

    The 2026 power units, will maintain the current V6 internal combustion engine architecture but they feature increased electrical power and 100% sustainable fuels, which are the two factors Audi say were key to joining the sport.

    Audi – who are part of the Volkswagen Group – added that it also supports F1’s future plans to be more sustainable and cost efficient, with a cost cap for power unit manufacturers introduced in 2023 as well as F1 setting a target of being Net Zero Carbon by 2030.

    Audi Sport’s facility in Neuburg will be where the power unit is developed, marking the first time in more than a decade that F1 powertrain will be built in Germany.

    Audi say there are already test benches for F1 engine testing as well as for electric motor and batter testing in their Neuburg base. They are now currently working on getting personnel, buildings and technical infrastructure in place by the end of the year.

    Adam Baker, who has held several senior positions for manufacturers and teams in motorsport whilst also spending three years with the FIA, he will now run the Formula 1 project as CEO.

    I am delighted to welcome Audi to Formula 1, an iconic automotive brand, pioneer and technological innovator. This is a major moment for our sport that highlights the huge strength we have as a global platform that continues to grow. It is also a big recognition that our move to sustainably fuelled hybrid engines in 2026 is a future solution for the automotive sector. We are all looking forward to seeing the Audi logo on the grid and will be hearing further details from them on their plans in due course.

    F1 President and CEO, Stefano Domenicali.

    Motorsport is an integral part of Audi’s DNA. Formula 1 is both a global stage for our brand and a highly challenging development laboratory. The combination of high performance and competition is always a driver of innovation and technology transfer in our industry. With the new rules, now is the right time for us to get involved. After all, Formula 1 and Audi both pursue clear sustainability goals.

  • FIA approve PU regulations for 2026

    The FIA World Motorsport Council has approved power unit regulations set to come into effect for the 2026 season with increased electrical power and 100% sustainable fuels two of the key aspects of the newly-approved rules.

    The 2026 power units will maintain the current V6 internal combustion engine architecture, with the FIA setting out four key pillars of the new regulations, which are:

    • Maintaining the spectacle – the 2026 power unit will have similar performance to current designs, utilising high-power, high-revving V6 internal combustion engines and avoiding excessive performance differentiation to allow for improved raceability.
    • Environmental sustainability – the power unit will include an increase in the development of electrical power to up to 50% and utilise a 100% sustainable fuel.
    • Financial sustainability – financial regulations regarding the power units will reduce the overall costs for competitors whilst retaining the cutting edge technological of Formula 1.
    • Attractive to new power unit manufacturers – the new regulations are intended to make it possible and attractive for newcomers to join the sport at a competitive level.

    The regulations will see the current Motor Generator Unit Heat or MGU-H element removed whilst the power output on the power units’ Energy Recovery Systems will be increased to 350 kilowatts.

    The FIA continues to push forward on innovation and sustainability – across our entire motor sport portfolio – the 2026 Formula 1 Power Unit Regulations are the most high-profile example of that mission. The introduction of advanced PU technology along with synthetic sustainable fuels aligns with our objective of delivering benefits for road car users and meeting our objective of net zero carbon by 2030. Formula 1 is currently enjoying immense growth and we are confident these regulations will build on the excitement our 2022 changes have produced. I want to thank all of the FIA management and technical staff involved in this process for their diligence and commitment in working together with all of our Formula 1 stakeholders to deliver this. I also want to thank our WMSC members for their consideration and approval of these regulations.

    FIA President, Mohammed Ben Sulayem.

    2022 & 2023 porpoising and roll hoop regulations approved-

    The WMSC also approved changes to the 2022 and 2023 Technical Regulations, designed to address both the issue of aerodynamic porpoising and of safety standards for roll hoops.

    With regards to porpoising, it has now been approved that from this months Belgian Grand Prix until the end of the season, there will be changes to re-define the stiffness requirements of the plank and skids around the thickness measurement holes on the cars.

    From 2023, meanwhile the following changes will be made:

    • The floor edges will be raised by 15mm
    • The diffuser throat height will be raised
    • The diffuser edge stiffness will be increased
    • An additional sensor will be mandated to monitor the porpoising phenomenon more effectively.

    Additionally, follow Zhou Guanyu’s crash at the 2022 British Grand Prix, the following changes surrounding safety standards for the roll hoops on F1 cars were also approved to become of the 2023 Technical Regulations:

    • A rounded top will now be required on the roll hoop, which will reduce the chance of it digging into the ground during an incident.
    • A change will be made to ensure a minimum height for the point of application of the homologation test.
    • There will be a new physical homologation test where the load pushes the roll hoop in the forward direction.
    • There will be a definition of new tests, to be carried out by calculation.
