In the second episode of Grove Insider, Williams Racing takes fans inside one of the most vital yet rarely seen aspects of Formula 1 preparation: the simulator. With F1 driver Carlos Sainz behind the virtual wheel, the episode explores how the team uses cutting-edge simulation technology at the Williams Racing Experience Centre in Grove, to prepare for race weekends with precision.
This simulator is something special and goes well beyond what even pro-sumers can purchase. It’s a high-fidelity replica of the car and circuit environment, complete with feedback systems, realistic controls, and adaptable conditions that mimic everything from tyre wear to track temperature. As Sainz puts it, “It feels almost real—but then I realise I'm still at Grove.” That realism is the point. Every lap driven in the simulator is a crucial part of race strategy and driver readiness.
The Race Engineer Gaetan Jego gives a behind-the-scenes look at the simulator control room, where real-time data is collected and compared to past race telemetry. His role is to ensure that every detail—from steering sensitivity to tyre performance—is monitored and fed back to the engineers. For example, the team runs multiple race simulations with different tyre compounds to assess degradation and performance. This data shapes race strategy decisions before the car ever hits the actual track.
Sainz explains how he uses the simulator to memorize braking zones, test cornering techniques, and adapt to evolving track conditions. Simulated weather changes—even a few degrees—can alter grip and brake feel, helping drivers prepare for a range of scenarios they might face on race day.
One of the most powerful aspects of the simulator is its ability to model “what if” situations. Whether it's rain hitting mid-race or a sudden drop in temperature, the simulator allows the team to rehearse their responses in advance. These preparations become even more essential with modern F1's limited on-track testing.
By the time the team arrives at the circuit, they’ve already driven hundreds of virtual laps, tested strategies, and fine-tuned the setup—all from inside the simulator suite. It’s a reminder that performance in Formula 1 doesn’t just begin on the grid; it starts weeks before, deep in the heart of Grove.
