Automotive industry in Chennai

Chennai is nicknamed the "Detroit of Asia" due to the presence of major automobile manufacturing units and allied industries around the city.

A number of big motor companies, including BMW, Royal Enfield, Hyundai, Renault-Nissan, Citroen, Caparo Group, Komatsu, Caterpillar, Ashok Leyland, and TVS, have presence along the 60 km Automotive Corridor. Oragadam is regarded as the epicenter of this corridor, which contains the National Automobile Testing and R&D Infrastructure Project (NATRIP). This corridor is served by three major ports, Chennai Port, Kattupalli Shipyard and Kamarajar Port.

The 4-wheeler vehicles in Chennai is the base of 30% of India's automobile industry and 35% of its automobile component industry. Besides the commercial industry, the Heavy Vehicles Factory (HVF) has been established in Avadi to produce military related vehicles. Avadi also has the Combat Vehicles Research and Development Establishment (CVRDE), with an engine-testing facility.
