2014
Info
Having participated in FSUK 2012 and FSG 2013, Raftar Formula Racing embarked on its third season. Fitted with a single-cylinder Honda CBR250R engine, we targeted excellent drivability and a competitive fuel economy. We worked to further enhance vehicle dynamics through a smaller wheelbase and a shift to 10” rims. Composite technology allowed us to use carbon fibre for an extremely ergonomic cockpit and a lighter streamlined bodyworks. A team of 30 highly motivated students bring you RFR-14.

2013
Info
FSG13 brought with it a new challenge to Team Raftar, as we redefined our goals & objectives, while retaining our passion and commitment. We began our Formula Student journey last year at the Silverstone and this year continue it at the Hockenheimring with a team of 30 enthusiastic and hardworking young minds. Our aims include large scale weight reduction, greater serviceability, and a balance between performance efficiency and driver convenience. We spent a large part of the year in detailed design and analysis leading to major changes in almost every subsystem. These included a changeover to the Honda CBR250R Engine, a new aerodynamics package comprising of wings designed to ensure better cornering, an optimized space frame chassis, an extremely lightweight and trustworthy suspension setup, streamlined FRP bodyworks and a careful study of ergonomics and driver comfort. We hope to outdo our expectations and lay a solid foundation for the evolution of the team over the year's to come.
