Perusahaan Otomobil Nasional Bhd., better known as PROTON, is Malaysia's largest manufacturer of automobiles, commanding as much as 65 percent of the domestic market. The company produces a full range of vehicle styles, from its popular Wira sedan to its own mini-van and sport utility models. While most of the company's car designs were previously based on re-branded models from its long-standing technical partner, Mitsubishi, in the 2000s Proton has begun developing its own technology in partnership with its 80 percent-controlled subsidiary Lotus, of U.K. sports and racing car fame.
