Tata Cummins Pvt. Ltd. is a 50:50 joint venture between Tata Motors Limited, India's largest automobile manufacturer and Cummins Inc., USA, world leaders in design and manufacture of diesel engines. The entity manufactures high performance, reliable and durable mid-range (B&L) engines in the 75 to 400 HP range that not only comply with current and future emission norms, but are also serviceable globally.

Established in the year 1994, the company started its operations with its state-of-the-art facility at the steel city of Jamshedpur. Aligning itself with the world class manufacturing standards, Tata Cummins Jamshedpur has consistently exceeded customer expectations which resulted in increased annual sales and demands for further capacity. Expansion plans were finally put in place with the setting up of the second and third manufacturing facilities at the Cummins Megasite in Phaltan, Maharashtra.
