The Endurance World Championship is preparing to return to action after a very long winter break, extended further by the rescheduling of the season-opening Qatar race. With so many variables in play, anticipation is extremely high ahead of the first Prologue sessions at Imola, scheduled for mid-April.
WEC, Ferrari: how the regulations are changing
The Imola circuit is considered one of the most technically interesting tracks on the calendar. The Emilia-Romagna layout highlights a car’s chassis strengths, demanding strong kerb stability and an optimal compromise between traction performance and front-end precision through fast direction changes.
From this perspective, the first major change comes into play: the aerodynamic window. Due to the relocation of the wind tunnel to Windshear in the United States, manufacturers have been forced to reposition their cars within the correct performance window defined by the regulations, revising key aerodynamic parameters.
It is worth remembering that the WEC rules impose maximum limits on drag and aerodynamic load, making it essential to reach an optimal compromise while also considering the effectiveness of the design department.
As reported by Ferdinando Cannizzo, the 499P demonstrated a highly effective operating window throughout last season. At Imola, a crucial part of the work will be mechanical grip: the Gresini and Acque Minerali variants highlight excellent suspension kinematics, ensuring—approximately—stronger traction phases.
This is particularly important out of Rivazza 2 and also at Tosa, where strong rear rotation reduces understeer and therefore tyre sliding. These traction characteristics remain essential for overall performance and tyre management.
The adjustments presented by Cannizzo during the launch of the 2026-liveried prototype have justified, at least on paper, the concerns shared by the engineers in Maranello. Clearly, significant setup work will be required to explore the most effective directions with the revised 499P.
To this must be added the changes in the technical regulations, which now include stricter flex tests. The Hypercar team was already on track at Imola on Tuesday, March 31, laying the groundwork for the upcoming Prologue test session.
WEC, Ferrari: how much will the tyres matter?
Ferrari remains confident in the potential of the 499P, which according to internal assessments is still only partially unlocked. However, these regulatory and technical changes could have an impact during the early part of the season, even though the Italian engineers are believed to have taken the most effective approach possible given the package available.
The new Michelin tyres, developed with reduced environmental impact, are designed to improve warm-up performance—a known weak point for Ferrari during race stints—alongside better consistency over longer runs.
The Italian team reportedly tested the new tyres only in limited quantities, focusing primarily on the medium compound. Nielsen, one of the few drivers able to try the new Michelin Pilot Sport Endurance 2026 tyres, expressed optimism, while Giovinazzi noted a change in car balance.
Last year, the 499P’s strength in tyre management represented a major advantage, even though it still showed weaknesses in the early phases of stints. This area is theoretically expected to improve.
The inability to test at circuits like Sakhir or Lusail limits detailed tyre development work, as teams cannot fully evaluate behaviour under extreme conditions like high asphalt abrasiveness and lateral energy load.
Rivals like BMW, Cadillac, and Aston Martin have already completed significant mileage on the new tyres thanks to the recent IMSA endurance campaign in Florida.
Heinrich, winner of the recent 12 Hours of Sebring in the Porsche #7, highlighted how even in the intense Florida heat, double-stint tyre runs were possible on a very demanding circuit. He also emphasized that from the beginning to the end of each stint, the tyres remained within their optimal operating window.
This suggests a potential levelling of performance in this area, making it harder for cars like the 499P to maintain a late-stint advantage. It is also worth noting that Porsche currently remains the benchmark in the American series, benefiting from a highly effective platform that optimizes tyre performance.
Only Cadillac appears close to matching Penske’s dominance, with Aitken confirming the strong performance of the new Michelin tyres, also in terms of degradation control.
WEC, Ferrari: will the updated PPU also appear in WEC?
One of the IMSA BoP innovations is the new management system for power unit output limits. Previously, if a limit was exceeded, power would take a long time to return to full deployment. Now, the system theoretically allows a more flexible use beyond the threshold, albeit in a highly controlled manner.
In IMSA, the PPU limit integrator allows for improved power recovery. Teams that are strong in software management—an area where Ferrari is considered ahead, could potentially benefit from this system in more effective energy deployment strategies.
If such a system were also introduced into WEC, it could significantly amplify these advantages, especially when combined with the expected BoP adjustments.
The next key milestone will be the Prologue on April 14, ahead of the first race weekend of the season.
