Cadillac's F1 Car Has Like 10 Miles of Wiring Inside

That loom exists to feed a constant stream of data. Sensors placed across the machine watch engine performance, tire pressures, and how fast air moves around the bodywork, according to General Motors. They also log directional changes. Every reading is captured down to the millisecond.

Those readings do not stay with the car. Data flows to trackside engineers and to the team's operations hubs in Silverstone, England, and Charlotte, North Carolina. While the driver manages grip and defends position, personnel on another continent can study what is happening beneath the bodywork in real time.

GM says the data informs in-race calls and the groundwork laid for later rounds. The readings also feed the Charlotte driver-in-the-loop simulator, where the team gauges the car's sharpness, responsiveness, and predictability even when it is nowhere near a track.

The simulator turns the collected data into time and cost savings. Cadillac has described in earlier coverage how Valtteri Bottas jumps straight into the sim after a race, lining up what he felt in the real car with what the virtual version delivers. Aligning the two lets GM hone the actual car and give drivers meaningful practice in a safe virtual environment.

The approach has already produced results. Before the 2026 Miami Grand Prix, support driver Aiden Price tested a virtual suspension change on the rig. Once the team trusted the improvement, Greg Price, GM's design and manufacturing manager, arranged for the parts to be made and flown out to Miami by the next morning.
