Tata Motors entered the passenger car market in 1991 with the launch of Tata Sierra, making it the first Indian producer to produce its own cars. In 1998 Tata launched a "truly Indian" passenger car, Tata Indica. In 2004 Tata purchased the Daewoo truck unit which is now called the Tata Daewoo Commercial Vehicle. In January 2008, Tata introduced the Tata Nano, which is the cheapest car in the world. In March 2008, Tata Motors acquired Jaguar and Land Rover.
