A part of Birla Group, Hindustan Motors started its production in 1942. Its car Ambassador had great success with the Indian consumers and soon became an icon. Contessa is another product of the company. Later, due to lack of innovation and old designing, Ambassador lost its charm and the entry of Maruti Udyog saw Hindustan Motors losing its market share consistently. These days Hindustan Motors produces automobiles in collaboration with Mitsubishi of Japan.
