Michigan could soon receive a major economic push from General Motors. The automotive company is expected to announce on Tuesday the addition of 1,400 jobs and a $450 million investment plan for its Detroit-Hamtramck and Brownstown Township production facilities.

This announcement is predicted to take place during the Automotive Press Association luncheon this afternoon in Detroit. Although a spokesperson for GM failed to comment, it has been confirmed that both Detroit Mayor Mike Duggan and Governor Rick Snyder have been invited to the event to discuss “ongoing investment to maintain its technology leadership.”

The company is anticipated to invest further in electric car research in an attempt to redesign the Volt for 2016. Last year, GM announced an investment of $121 million to improve logistics for Volt production in Detroit. However, the company reported nearly a 60% decline in Volt sales in 2013.
