In 2012, a team of 30 mechanical engineering students from IIT-Bombay became the first Indians to build an all-electric racing car to compete at the Silverstone Formula-1 racing track in the UK, as part of the IIT Racing competition — Urmil Shah, Pushkar Limaye, Rohan Vadgaonkar and Prathmesh Joshi. After graduating, the four friends went their separate ways, chasing a future in the corporate world. Auto, however, continued to remain a passion.
