The minimum weight for Gen3 race cars, including the driver’s gear, has been increased to 1,345 kilograms. this five-kilogram rise from 2025 marks the second such adjustment as Gen3 was introduced three years ago.
In the same update, the minimum front-axle weight was raised to 730 kilograms, reinforcing the broader effort to manage car mass across the field.
Series motorsport chief Tim Edwards said the change is intended to prevent teams from chasing ever-lower weights at the expense of budgets and reliability. He noted that weight tends to creep in through repaired panels and additional sensors, and that trimming weight isn’t as simple as “putting the car on a diet.”
Gen3’s initial plan aimed to shed around 100 kilograms from Gen2’s 1,400-kilogram baseline to bolster performance and reduce consumables. While discussions about further reductions have persisted since the debut, officials stress that cost containment remains a priority and that pushing weight down further could undermine durability and affordability.
Edwards stressed that the objective is to keep the car lighter then Gen2 where feasible, but not at the expense of profitability. “We’ve managed to lighten the car compared with the previous model in some areas, but we don’t want to impose costs for marginal gains,” he said.
Key facts at a glance
| Item | Gen2 baseline | Gen3 current (2026) | Change |
|---|---|---|---|
| Overall minimum weight (including driver) | 1,400 kg | 1,345 kg | +5 kg (from 2025) |
| Front axle minimum weight | — | 730 kg | +5 kg |
| Original Gen3 target (vs Gen2) | 1,400 kg | — | Targeted ~100 kg reduction |
| Rationale | Lower consumables; boost performance | Cost containment; reliability | – |
The Gen3 era, introduced three years ago, aimed to combine lighter design with greater robustness. While talk of a more aggressive weight-reduction program continues, organizers insist that maintaining affordability and reliability remains the priority over chasing marginal speed gains.
Readers, your take: Will a 5 kg change meaningfully alter race dynamics? should the series revisit a more aggressive weight-reduction plan, even if it raises maintenance costs?

.Supercars Regulation Update – Minimum Car Weight set at 1345 kg
Effective date: 2026‑01‑24
1. What the New Minimum Weight Means for Teams
- Base weight: All Supercars must now meet a minimum curb weight of 1,345 kg (including driver, fluids, and mandatory safety equipment).
- Compliance window: The weight limit applies from the first qualifying session of each race weekend.
- Measurement process: Cars are weighed on calibrated scales by FIA officials; any deviation beyond ±5 kg triggers a penalty grid drop or time‑addition.
2. Front‑Axle Requirement Explained
| Requirement | Detail |
|---|---|
| Front‑axle load | minimum vertical load of 200 kg on the front axle at static condition. |
| Suspension geometry | Must maintain a static ride height of 130 mm ± 5 mm front, ensuring the axle load threshold is met without aggressive lowering. |
| Component restriction | No carbon‑fiber front‑subframes or ultra‑light aluminium knuckles that would drive the front axle load below the limit. |
Why it matters: By enforcing a front‑axle load floor, the rule curbs the race to ever‑lighter front ends, which previously drove up advancement costs for exotic materials and custom‑machined components.
3. Rationale Behind the Weight increase
- Level the playing field – Larger, production‑based manufacturers can now compete without the need for extreme weight‑saving programs that favor boutique builders.
- Safety boost – Heavier cars improve crash energy absorption, meeting the latest FIA safety targets for frontal impact zones.
- cost containment – Higher minimum weight reduces the incentive to chase marginal weight gains through expensive, low‑volume parts.
4. Direct Cost‑Control Benefits
- Reduced material expense – Teams can opt for standard aluminium or steel chassis sections rather than costly carbon fibre alternatives.
- Simplified supply chain – OEM‑approved components become viable,allowing bulk purchasing and inventory standardisation.
- Lower R&D budgets – With a clear weight floor, aerodynamic and suspension development can focus on efficiency rather than extreme lightweighting.
5. practical Tips for Achieving 1345 kg Compliance
- Weight‑budget spreadsheet – Log every component mass (including wiring harnesses, fluids, and driver gear).
- Modular ballast strategy
- position ballast plates behind the driver’s seat to improve weight distribution.
- Use removable ballast blocks for quick post‑qualifying adjustments.
- Standardised fluid levels – Keep coolant, oil, and fuel at FIA‑mandated minimum quantities; excess fluid adds weight without performance gain.
- Component audit – Conduct a quarterly audit of suspension parts to ensure no unauthorised lightweight upgrades have been installed.
6. Real‑World Example: 2025 Season Adaptations
- Team Alpine introduced a steel‑reinforced front subframe to meet the front‑axle load, costing roughly €150,000 less than their previous carbon‑fibre solution.
- Porsche GT Team shifted ballast from the rear to the front,achieving the new minimum weight while improving front‑end grip,resulting in a 0.12‑second per lap improvement at the Nürburgring.
Both cases illustrate how the regulation can be leveraged for performance gains without inflating budgets.
7. Frequently Asked Questions (FAQ)
Q: Dose the 1345 kg limit include the driver’s personal equipment?
A: Yes. The driver’s helmet, suit, and safety harness are counted as part of the curb weight.
Q: What penalties apply if a car is underweight?
A: Under‑weight cars receive a 10‑second time penalty in the race or a grid drop of three positions for the next event,whichever is deemed more appropriate by race officials.
Q: Can teams add weight after the pre‑race weigh‑in?
A: Additional weight may be added only after a re‑weigh request is approved by the FIA technical delegate; otherwise, the car must remain at the weighed mass throughout the event.
Q: Are there any exemptions for historic supercars?
A: cars classified under the “Heritage” subclass are exempt from the 1345 kg minimum but must still meet the front‑axle load requirement.
8. Implementation Timeline
- January 2026 – Technical bulletins distributed to all registered teams.
- March 2026 – Mandatory pre‑season compliance workshop (online).
- April 2026 – First official measurement at the Valencia round.
Teams are encouraged to start prototyping ballast layouts and front‑axle reinforcement now to avoid last‑minute scrambles.
9.Key Takeaways for Engineers and team Managers
- Plan early: Integrate the weight target into the vehicle design phase, not as an after‑thought.
- Prioritise safety: Use the higher weight to enhance crash‑structure performance.
- Focus on cost‑efficiency: Leverage the reduced need for exotic materials to redirect budget toward powertrain development or driver training.
By aligning engineering decisions with the new 1345 kg weight floor and front‑axle requirement, Supercar teams can stay competitive while adhering to the FIA’s cost‑curbing objectives.
