Tesla Roadster could be 5 s faster than F1 at COTA. I simulated a lap with the revealed specs: 1:27.9 vs Verstappen's 2025 pole at 1:32.5. Where it wins: acceleration. All-wheel drive, 2 g of fan suction keeping the tyres planted on exits, and cold-gas thrusters. Top speed on the back straight: 374 km/h vs 324. At the end of the lap the temperature in the tank is -150 Deg C. Where F1 wins: braking and the fast corners. An 800 kg car with downforce that grows with speed beats a 2-tonne one. As @elonmusk said the tires are the biggest limiting factor, I assumed quite conservative values taking into account the massive vertical forces that they would have to endure.
