Info
Raftar Formula Racing presents the RFR24, our latest electric car, embodying lessons from the RFR23. This data-driven machine sets new benchmarks for reliability and mechanical prowess. As a second-year FSAE Electric team, we focused on reliability, optimization, and design validation. We rigorously tested the car for 250 km, reduced its weight by 20 kg, and fine-tuned every subsystem targeting redundancies and enhancing performance. This effort lays a strong foundation for future cars.
Engineering Design Priorities:
Decoupled Suspension
Custom BMS
Drag Reduction System
