In a move which General Motors (GM) claims is aimed at trimming its excess inventory, the automaker has decided to stall the production of its Chevrolet Volt battery-powered cars for 26 days --- most likely from September 17 to October 12.

With a GM spokeswoman confirming the four-week temporary suspension of the production of Chevrolet Volt at the Hamtramck, Michigan, plant, it is for the second time this year that the manufacturing of the plug-in sedan has been idled by the automaker.

The four-week halt in production of Volt at the Hamtramck plant will affect nearly 1,200 hourly workers, who will - according to the information shared by a union source - receive unemployment compensation during shutdown period. The compensation will amount to approximately 90 percent of their normal salary.

In a confirmation that the Hamtramck plant is being idled for nearly four weeks in September and October - though not officially confirming the dates -, GM said that it will continue to "match supply with demand" for the Volt as well as the Chevrolet Malibu sedan which is also manufactured at the same plant.

Asserting that the Volt is "doing great" and gaining sales each month, and would likely report robust sales for August as well, GM said that the shutdown of production at the Hamtramck plant will give the company some time for retooling and other work, in preparation for early-next-year production of the redesigned 2014 Chevrolet Impala sedan.
