Team Profile:
We are a group of students from IIT Bombay who are united by our passion for engineering, and our desire to fulfill this dream. Being from one of the most prestigious universities in the country, we share a common goal of putting India on the world map of race-car engineering.
IIT Bombay Racing has a three tier team structure under three verticals. The Mechanical and Electrical subsystems are respectively headed by a Chief Engineer and compose of Design Engineers and Junior Engineers. The third vertical, Administration headed by the Chief Operations Officer comprises of Project Managers and Junior Executives. Our structure has been designed to promote better co-ordination, enhance work culture and ethics and ensure sustainability by smooth passing on of knowledge.
EVo 3.0 has been designed with 3 goals in mind- Weight Reduction, Reliability and Tunability. Our target has been to design a reliable car while staying under the 250 kg mark. The vision of our electrical division has been to improve system integration and incorporate wireless high-speed Data Acquisition for tunability.
We would like to thank our institute as well as our sponsors NRB, TCS, Bosch, LEMO, MathWorks, Eternus, Lynch Motors and Imaginarium for their immense support.
Additional information
We probably are one of the largest teams in the event with around 70 team members (including 3 female members)!
We cooperated closely with Warwick’s IC team, experts in power electronics and battery technology at Warwick Manufacturing Group (WMG) and key sponsors such as Catapult, National Instruments, Enerdel and Infineon. The team believes passionately in the potential of electric vehicles, and is proud to contribute towards this sustainable vision.
