GM Readies Tennessee Plant to Make V-8 Engines

General Motors Co. says it is spending $148 million to prepare its plant in Spring Hill, Tenn., to make 6.2-liter V-8 engines for its large trucks and SUVs.

GM already produces the same small-block engine at factories in Tonawanda, N.Y., and St. Catherines, Ontario. The company says it needs more capacity to meet consumer demand for the powerplant, which is used in such vehicles as the Chevrolet Silverado fullsize pickup and Cadillac Escalade luxury SUV.

V-8 production at Spring Hill is slated to begin late this year. The Tennessee facility, originally erected to make Saturn cars, currently builds 4-cylinder engines and the Cadillac XT5 and GMC Acadia midsize crossover vehicles.
