In "Ford v Ferrari," the difference in mileage between the two teams during the 1966 24 Hours of Le Mans race can be attributed primarily to the different racing strategies and car reliability.
Ford developed the GT40 with a focus on speed and power, aiming to achieve superior performance over the entire 24-hour duration. The Ford team worked to optimize the car's aerodynamics and engine performance, while also implementing a rigorous pit stop and maintenance strategy to ensure that the car was always operating at peak efficiency.
On the other hand, Ferrari faced challenges such as mechanical issues and reliability problems during the race. The Ferrari team had originally been favored to win but struggled with car performance and pit stop inefficiencies, which ultimately resulted in less distance covered compared to Ford's GT40.
In the end, the combination of Ford's strategic planning, engineering excellence, and the endurance of the GT40 contributed to their ability to cover more miles than Ferrari in the grueling race.
