The MG Birmingham plant has resumed its first large scale car productions since cutting 6,000 jobs when MG Rover went into administration in April 2005.
The British designed five-seater, 1.8l engine MG6 is assembled in Longbridge from parts made in China. It is the first new MG model to be mass produced in the UK for 16 years.
MG itself is owned by China's largest car manufacturer, Shanghai Automotive Industry Corporation.
Local MP Richard Burden said that although it is impossible to "bring back the days when thousands were employed on Longbridge production lines", it was time to "build a future in the 21st century."
The MG6 is expected to cost from £16,000 to £19,000.
