Porsche Penske Motorsport ends its factory WEC programme after three seasons, confirmed last Saturday. The withdrawal triggers immediate questions about Porsche’s presence at Le Mans and how Roger Penske returns.
The programme delivers three wins, a pole, a Le Mans runner-up, and a drivers’ title. The finale underscores the downturn, with the cars finishing 13th and 14th.
Regulations complicate Penske’s route back. The IMSA champion only gets an automatic Le Mans entry if two Porsche 963s contest the full WEC season under a compliant banner.

Discussions focus on a partnership with Proton Competition. The privateer shares the setback from the factory exit and offers a pathway to a two-car commitment.
Under the proposal, Proton fields a second 963 and covers the manufacturer entry fee. The combined team runs with Porsche branding to satisfy WEC naming requirements.
Ferdi Porsche, via FAT Turbo, signals support for the alliance. That backing strengthens the customer-led route while preserving distance from a full factory return.
If approved, Penske can claim the IMSA-earned Le Mans invitation. A request for an additional Le Mans slot remains possible but depends on capacity and competitor demand.

Scheduling is tight. IMSA rounds sit close to the Le Mans Test Day and the race itself, increasing logistics risk. Penske appears prepared to absorb that complexity.
Porsche approval remains decisive. Vice-president Thomas Laudenbach stresses the factory exit does not change customer racing support, keeping technical and operational assistance available.
Internally, opinions differ. Some question a swift re-engagement in the manufacturers’ championship, while others prioritise repairing relationships with the ACO and FIA for long-term positioning.
Porsche’s Le Mans heritage, often driven by customer teams like Kremer and Joest, supports this approach. Multiple 963s under varied banners would fit that tradition.
WEC entries close November 27, with confirmations to follow. Whether Penske and Proton field two 963s in 2026 remains unresolved, but the pathway clearly stays open.
