2011 Chevrolet Cruze & 2011 Chevrolet Volt

General Motors Co. said Tuesday it will invest more than $230 million in four plants around Flint, Mich., to help build the 2011 Chevrolet Cruze compact and the Chevrolet Volt plug-in hybrid sedan.

The move will restore about 500 jobs, GM said in a statement.

The four GM plants that will be updated and retooled include Flint Engine South, Flint Metal Center, Flint Tool and Die and Grand Blanc Weld Tool Center.

“These four GM manufacturing plants have a key role in GM’s production of the next generation of fuel-efficient vehicles, the Chevrolet Volt and Cruze,”
