Re-engineering for Vanwall's Return in WEC 2025

In pursuit of returning to the forefront of the World Endurance Championship for 2025, Vanwall is redesigning its Vandervell 680 LMH with substantial upgrades. Although the team did not secure a spot in the 2024 season, dominated by the arrival of big names like Lamborghini and BMW, their efforts to compete next year have not ceased.

The German firm's Le Mans car will undergo a comprehensive overhaul, highlighting the replacement of its 4.5-liter Gibson engine with a more robust 3.5-liter twin-turbo V8 from Pipo Motors, previously powering the Glickenhaus SCG 007 LMH. This change is significant as the Gibson engine has shown power limitations, lacking up to 60kW or 80bhp to comply with the Balance of Performance system, directly affecting its straight-line performance.

Pipo's new engine, originally developed to achieve up to 850hp under Hypercar regulations, far exceeds the required 520kW, thus offering a superior performance margin. This change brings about a series of adaptations in the vehicle's design. The monocoque will be retained to avoid new impact tests, but peripheral systems will be extensively modified.

Adjustments include a new intercooler and an exhaust system with a modified angle, necessary due to the differences in the new engine. These modifications also require alterations to the bodywork that will influence the car's aerodynamics. Additionally, independent aerodynamic improvements are being made to optimize performance within the established limits.

Furthermore, the engine change entails the installation of a new seven-speed gearbox, replacing the previous six-speed. This implies a complete overhaul of the car's electronics, including an update to the latest specification of the Cosworth control system. A cable-operated brake system is also being introduced to improve stability during braking, along with discs and pads adapted to the vehicle's new thermal needs.

With these upgrades, Vanwall aims to substantially enhance the technical capability of the Vandervell 680 LMH. Anticipating the 2025 regulations, which require two vehicles per manufacturer, the team is preparing to meet these requirements and strengthen its competitive position. The approach encompasses both technical and strategic adjustments to ensure effective participation in accordance with the new WEC regulations, thus becoming part of the expanded grid of competitors.
