Auto News - After 25 years, GM ditches NUMMI tie-up with Toyota

As part of its "New GM"/"Old GM" bankruptcy proceedings, General Motors has announced that it will abandon its ownership stake in the New United Motor Manufacturing Incorporated (NUMMI) joint venture with Toyota.

According to an official statement, GM and Toyota worked to find a future product that would work for both automakers, but they were apparently unable to do so. As a result, GM will assign its NUMMI stake to "Old GM," effectively ending a 25-year partnership with the Japanese automaker.

Over the last quarter-century, the Fremont, California plant has produced a number of vehicles for GM, including the current Pontiac Vibe, as well as the Geo/Chevrolet Prizm, and the Bowtie'd Nova that preceded it.

There is no word on what (if any) effect the deal's collapse will have on Toyota's NUMMI-made products which include the Tacoma pickup and Corolla sedan. According to NUMMI's official website, 5,440 workers are employed at the plant. Official press release after the jump
