F1 Movie Team Builds Electric Car: The Story Behind It
Fictional Racing’s Secret: Why Electric Cars saved the Day on the Apex Grand Prix Set
The high-octane world of fictional racing frequently enough demands more than just skilled drivers and dramatic crashes.For the creators of the Apex Grand Prix (APXGP), a groundbreaking fictional racing series, the challenge was to capture the raw intensity of motorsport on screen.However, the very technology meant to simulate this reality – the Formula 2 car’s ECU (Engine Control Unit) - presented an unexpected hurdle, leading to an ingenious solution: building an electric version of the car.
The ECU Conundrum: A Locked Box of Secrets
According to Kelly, a key figure involved in the production, the limitations imposed by the real-world Formula 2 car’s ECU were notable.”We were not allowed to go anywhere near [the ECU]… all the teams would have loved to have got some details out of that ECU, but no, the ECU was sealed,” he explained.This meant the production team could only make superficial modifications, like altering gear ratios, but had no access to the engine mapping.
This lack of control over the engine mapping had a direct impact on managing crucial engine temperatures during filming.”The engine – in our process of doing a run, coming back in, talking about it, going back out again – we were playing with temperature all the time,” Kelly elaborated. “And with the brakes as well, not just with the engines.” The constant need to manage heat meant that prolonged filming sessions with the actual F2 car were impractical and risky.
The Electric Revelation: A Simpler, More Reliable Solution
Faced with these technical constraints and the impracticality of managing a high-performance combustion engine for repeated filming sequences, the team arrived at a simple yet effective solution: build an electric version of the APXGP car.
Kelly’s background in the film industry proved invaluable. He understood the demanding nature of capturing dynamic shots, especially those involving pit stops. “Because of the experience I’ve had in the film industry, knowing the process that we go through to have a Formula 2 car with a Mecachrome engine come into the pitstop with us, doing a pitstop, filming it, stopping it, pushing it back, doing it again,” he recalled. “That would have lasted 10 minutes before it would have gone catastrophically wrong.” The constant starting, stopping, and repositioning required for filming would have quickly overwhelmed the cooling systems of a real F2 car.
“So I decided pretty early in this process that we should build an electric car,” Kelly stated, highlighting the pivotal decision that steered the production towards a more sustainable and practical approach for on-set operations.
The Electric APXGP: Power, torque, and endless takes
The all-electric APXGP car was a marvel of engineering designed specifically for the rigors of filmmaking. It featured a 400-volt Helix motor directly connected to the gearbox, with the batteries cleverly housed beneath the engine cover. This setup offered distinct advantages for the production.”In first gear, it would do 70mph… and it would do 70mph backwards. And we would do that probably for two hours. And it was great,” kelly enthused. The electric powertrain provided instant torque, allowing the actors to execute dramatic wheelspins and maneuvers with ease.Crucially, the team no longer had to worry about the car overheating or “exploding because it had got hot.” This meant they could perform takes repeatedly,ensuring the perfect shot without the constant threat of mechanical failure due to heat.
Kelly offered a interesting insight into the visual deception employed in the film: “So when you see the film, you’ll see a car boiling out of the pitlane with a screaming engine, but actually what you could be watching was actually the electric car. But I guess you can’t tell.” This highlights the seamless integration of the electric car into the narrative, masking its true nature and delivering the authentic racing spectacle audiences expect. the electric APXGP car not only solved the technical challenges but also proved to be a more reliable and versatile tool for bringing the fictional racing world to life.
