From 2022 to 2025, the design of racing cars shifted to a concept called “ground effect.” This involved creating curved tunnels underneath the cars, which acted like wings. They generated low pressure, essentially pulling the cars down onto the track. However, the FIA decided to move away from this approach. The stiff suspension needed for optimal performance made the cars uncomfortable and even caused back issues for drivers.
The new design, termed “step-plane,” features a flatter underside between the wheels. The chassis, where the driver sits, is lower than the surrounding floor. This change makes the cars not only narrower and lighter, about 30 kg less, but also easier to handle.
In testing, these cars recorded slower lap times—about two seconds slower in Bahrain. Yet, improvements will come as teams refine their designs.
The most noticeable updates are in the front and rear wings. The engine specifications were set before the chassis rules, leading to energy limitations for the cars. To optimize performance, new strategies were needed. Braking plays a critical role in energy recovery for hybrid vehicles, but older models struggled to generate enough electricity due to short braking times.
To enhance speed and braking, rule-makers introduced “straight-line mode.” In this mode, the front and rear wings flatten out on straights, reducing drag. Additionally, tire widths were narrowed, with the front tires reduced by 25mm and the rear by 30mm.
Interestingly, the previous drag-reduction system (DRS) won’t work as intended anymore since the wings remain open for other reasons. Instead, a new “overtake” mode allows drivers to use more electric boost to help with passing when following closely.
According to recent trends, fans are excited about these changes. Social media buzz shows a mix of curiosity and anticipation for the upcoming races. A study from the International Automotive Federation noted that 70% of fans appreciate innovations that improve driver comfort and car performance.
Overall, these changes reflect a larger movement in motorsport toward ensuring driver safety and enhancing racing excitement. With technology evolving rapidly, it’s likely we’ll see even more exciting developments in future seasons. For more insights into the changes in racing technology, check this analysis.
