Spring Hill, Tennessee – General Motors will invest US$483 million and add 483 jobs building current- and next-generation Ecotec four-cylinder engines at its powertrain complex in Spring Hill, Tennessee. The company said the investment is dependent on successful incentive negotiations with local and state officials.

Employees for the new positions will be recalled from layoff in accordance with a labour agreement between GM and the United Auto Workers.

“The engines made in Spring Hill will drive the success of GM to meet our customer demands for advanced powertrains which offer high fuel economy without sacrificing performance,” said Mark Reuss, president of GM North America. “This new commitment to the Spring Hill team will help GM almost triple its North American production volume of four-cylinder engines with direct injection by 2012.”

Currently, Spring Hill produces three engines: a 2.4-litre direct-injection four-cylinder used in the Equinox, Terrain, LaCrosse and Buick Regal, as well as the Chevrolet Captiva in Mexico and Daewoo Alpheon in Korea; a 2.0-litre diesel used in the Opel Insignia in Europe and Buick LaCrosse in China; and a 2.4-litre multiport fuel-injection engine that is shipped to Korea for the Captive and Antara.

The bulk of the investment is planned for the next-generation Ecotec engines. The investment does not involve the Spring Hill Assembly Plant, which is currently idle and remains on standby status should more vehicle production capacity be needed.
