Team Description

Raftar Formula Racing is the Formula Student team of IIT Madras. Founded in 2012 as a combustion team, we have competed in Formula Bharat, India's official Formula Student competition, as well as several prestigious international events, including Formula Student Germany, Formula Student UK, and Formula Student Italy.

The name "Raftar" translates to "speed" or "pace" in Hindi, reflecting the team's commitment to engineering excellence and continuous performance improvement.

Now in our 15th year of Formula Student participation and fourth year as an electric team, we are proud to present RFR26, our latest electric race car. Developed with a strong emphasis on data-driven design, reliability, optimization, and rigorous design validation, RFR26 represents a significant step forward for the team. Following over 400 km of testing and a mass reduction of more than 50 kg compared to RFR25 - made possible in part by the development of India's most energy-dense and power-dense battery pack - RFR26 stands as our lightest, fastest, and most refined electric car to date.

RFR26 also marks a major milestone in the team's journey, as it becomes the team's first vehicle to feature autonomous capabilities.

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
