The standing start has emerged as one of the most technically sensitive and highly scrutinized topics at the very beginning of this 2026 Formula 1 season. In the absence of an official, formal stance from the FIA, but in the presence of increasingly heated discussions and exchanges among the various teams, technical analysts and engineers have focused their attention on how the turbocharger is being managed in power units that no longer incorporate the motor-generator unit connected to the turbo shaft, known as the MGU-H.
At the very center of this ongoing debate is Ferrari, which has developed a technical solution capable of delivering a clear and measurable advantage during the crucial moment when the race lights go out and the cars launch from a complete standstill. This particular benefit, which several other competing teams have not yet been able to replicate with the same level of effectiveness or consistency, could potentially generate a speed differential over the first few meters of acceleration that raises legitimate questions regarding driver safety and the dynamics of tightly packed racing scenarios. This is precisely the issue that could potentially place Ferrari under significant regulatory scrutiny from the FIA.
The International Federation, as the governing authority of Formula 1 and the ultimate regulatory body responsible for all safety and technical compliance matters, has the explicit authority to intervene in such cases even without obtaining unanimous consent from all participating teams. Despite this, Ferrari has consistently maintained a firm and unwavering position: the technical approach implemented in their power unit represents a carefully considered and fully deliberate design choice. This choice was not made impulsively or opportunistically, but rather it was fully accepted and acknowledged by the FIA and meticulously developed from the very first day of defining the overall architecture of the 2026 power unit.
Abolition of the MGU-H: the critical start window
The complete removal of the MGU-H from the current generation of turbocharged engines has once again highlighted a structural and inherent challenge of turbocharged power units: turbo-lag, particularly during transitional phases such as the engagement of the clutch and the very first moments of vehicle acceleration. Without the assistance of the MGU-H, which previously could inject torque directly into the turbo shaft, the moment when the driver engages first gear results in a rapid and sudden drop in the rotational speed of the engine. The anti-stall system, which is automatically triggered in these scenarios, intervenes by momentarily disengaging the clutch in order to prevent the engine from stalling, but this creates an extremely delicate and sensitive temporal window in which the turbocharger tends to decelerate significantly and almost uncontrollably.
To manage this critical phase, every Formula 1 team relies on a carefully calibrated engine mapping, commonly referred to as the launch map, which actively regulates two fundamental parameters: the minimum engine rotational speed and the ignition timing. By deliberately delaying the ignition timing, part of the combustion process is effectively shifted into the exhaust manifold, producing a pressure wave that helps maintain the rotation of the turbine even when the exhaust gas flow is insufficient to fully sustain it on its own.
In the previous generation of hybrid power units, the MGU-H could directly inject torque into the shaft of the turbocharger, thereby almost completely compensating for the natural delay in turbo response. Today, however, engineers and power unit designers must rely exclusively on thermal management strategies and highly precise software calibration to achieve the same effect. This solution is inevitably partial and limited, leaving a structural vulnerability that is extremely difficult to completely eliminate. It is precisely within this fleeting time window, immediately following the release of the clutch, that Ferrari has managed to construct and exploit its own technical peculiarity, effectively creating an edge over the competition.
Compact turbine and inertia advantage: Ferrari SF-26’s deliberate choice
The Ferrari SF-26, the team’s latest race car for the 2026 Formula 1 season, is equipped with a turbocharger featuring a smaller radius compared to the average turbine used by most of its competitors. From a purely physical perspective, reducing the radius directly lowers the moment of inertia of the rotor. A rotating component with lower inertia requires significantly less energy to accelerate and, most importantly, to maintain its angular velocity when the flow of exhaust gases suddenly drops, which is precisely what occurs immediately after the driver engages the clutch during a standing start.
The critical point, therefore, lies in this fraction of a second immediately following the release of the clutch: the mass flow of exhaust gases drops drastically, creating a potentially unstable and challenging scenario for the turbocharger. In that specific time window, a compact and lightweight turbine retains its rotational momentum with a much lower energy requirement compared to a larger, heavier turbocharger.
The practical outcome of this technical decision is a quicker and more responsive launch off the starting grid, with a noticeable reduction in the delay between engine torque availability and torque transmitted to the wheels. It is important to emphasize that this is not solely an electronic issue: while the launch map can mitigate part of the phenomenon, the actual mechanical characteristics of the turbocharger determine the dynamic behavior of the car during the crucial first few meters of acceleration.
Naturally, any engineering choice involves a trade-off. A smaller turbine tends to reach its maximum flow capacity sooner, which could have implications for high-revving performance and prolonged full-throttle operation. In such conditions, a larger turbocharger is capable of sustaining higher flow rates and therefore can unlock a higher potential for peak engine power.
Ferrari may have judged this trade-off to be acceptable or may have undertaken significant work to mitigate its impact through meticulous optimization of the compressor, the wastegate, and the intake-side pressure management. In any case, the choice appears to reflect a comprehensive and systemic reading of the regulations rather than an opportunistic intervention aimed solely at gaining a short-term advantage.
Acceleration delta and safety considerations: the FIA’s regulatory role
The central point of contention lies in the acceleration differential observed in the first few meters after the lights go out. If certain cars, such as the Ferrari SF-26, are capable of delivering torque to the wheels more rapidly than other vehicles, the resulting speed differential before the first braking zone can be significant. In a racing context where visibility is limited due to the presence of multiple cars in close proximity and the track width is restricted, this differential could theoretically increase the risk of wheel-to-wheel contact and potential incidents.
The FIA, as the ultimate regulatory authority and overseer of all technical and safety matters in Formula 1, is fully empowered to intervene unilaterally in such scenarios. Even without unanimous agreement among all teams, regulatory changes or technical mandates could be introduced promptly. The technical options available to the FIA range from software-imposed limitations on turbo pressure management during the launch to a more fundamental review and revision of the starting procedure itself.
Ferrari’s response, however, has been clear and methodical. The Italian team maintains that if the FIA initially decided to exclude changes to the starting procedure, intervening at this stage would effectively alter the regulatory framework after the engine architectures and power unit designs have already been finalized, which would be unfair and counterproductive from an engineering perspective.
Frédéric Vasseur and Charles Leclerc: compact turbo, a conscious and deliberate choice
Frédéric Vasseur, Ferrari’s team principal, defended the Maranello approach in a detailed interview with Motorsport, explaining that it was always clear from the outset that, without the MGU-H, managing turbo-lag would become a critical factor in the power unit’s performance. The French manager clarified that this issue was fully understood from the very first day and that the team carefully considered not only peak power output but also other important performance parameters, including the car’s behavior during standing starts, when making decisions about the overall design and architecture of the 2026 power unit.
Fred Vasseur also expressed his surprise that the issue re-emerged during the pre-season testing in Bahrain, highlighting that the FIA had been sufficiently clear from the beginning regarding its intention not to modify the starting procedure. He emphasized that, while it is easy for a driver to raise a question about safety or other technical aspects, all the relevant details had been fully known and accounted for by the engineering team for a long time. He further explained that when designing a modern Formula 1 power unit, engineers must always make compromises: on one side, the goal is to extract the absolute maximum possible engine power, while on the other side, drivability and control remain equally crucial. Decisions must always balance these sometimes competing objectives.
Charles Leclerc also confirmed that the subject of standing starts was carefully considered from the very early stages of the project. The Monegasque pointed out that the team had examined these scenarios in detail when beginning to focus on the new regulations for the 2026 season, and that standing starts were not considered a particularly critical area for Ferrari compared to other aspects of overall race performance.
Ferrari’s position remains consistent with its long-established design philosophy: the advantage gained at the start is not an incidental or accidental effect but the result of a carefully considered and fully deliberate technical compromise between achieving maximum engine power and maintaining optimal drivability. Going forward, the balance between safety and technical merit will be a determining factor. Should the FIA judge that the acceleration differential at the start represents a concrete safety risk, it retains the authority to intervene and implement corrective measures.
However, from the perspective of Ferrari in Maranello, the issue remains fundamentally a matter of principle: innovation and intelligent engineering solutions that fully comply with the technical regulations should not be treated as anomalies that require correction simply because they provide a competitive advantage. The debate and scrutiny surrounding this topic remain wide open, with tensions high, just hours before the first green light is shown at the Albert Park pit lane in Melbourne, marking the start of the opening race of the 2026 Formula 1 season.
