A Training Program on Automobiles by Bosch Training Centre, BOSCH Automotive, and the world's largest supplier of advanced electronic automotive systems was held from 18th-21st March, 2013 at Dronacharya Group of Institutions, Greater Noida. The program was meant for III year students of Mechanical Engineering.

Vehicle manufacturers from around the world rely on Bosch for innovation and technical expertise. Bosch is market leader in developing new vehicle systems, which provides direct access to the valuable information required for training courses and market leading range of diagnostic equipment. This training course followed a vehicle systems based approach as opposed to a vehicle specific approach so that the skills learnt can be applied across all makes of vehicles.

The training program was inaugurated by Prof. (Dr.) M. S. Murali, Director DGI. Mr. Parag Kavthekar, Regional Trainer, Bosch Automotive and Mr. Gaurav Dixit, Local Trainer Bosch Automotive were the resource person for the inaugural day.
