For the 2023 F1 season, aerodynamic rules underwent major changes, reintroducing the ground-effect technique, absent since the '80s. This transition aimed to reduce "dirty air" caused by wing-based downforce. The modifications focused on the car's underside, notably venturi tunnels, for downforce.

Additionally, 18-inch tyres were introduced, bodywork was adjusted, and bargeboard devices were eliminated. Although these cars showed slightly reduced speed than in 2021, they excelled in high-speed corners. A challenge was "porpoising" on straights, affecting drivers. To tackle this, the FIA introduced the Aerodynamic Oscillation Metric (AOM) in 2022 and 2023 to ensure safety.

Conclusion

Tracing the trajectory of F1 cars from the 1950s to the present, it's evident that they embody the spirit of relentless innovation and adaptability. Each era, from the raw power of the Alfetta to the sophisticated hybrids of today, demonstrates the motorsport's commitment to pushing the boundaries of what's possible on the racetrack.

Moreover, as the world grapples with concerns about sustainability and environmental impact, F1's shift towards more eco-friendly technologies like hybrids showcases the sport's willingness to be a part of the solution, while still maintaining its essence of high-octane racing. The reintroduction of features like the over-wheel winglets and the continuous advancements in aerodynamics, tire technology, and fuel efficiency point towards a better future.
