GM Spends Ton in Tonawanda, Adds Spring to Spring Hill Engine Plants by Evan Williams January 17, 2020 Share Comments General Motors has just announced a pair of investments to two of it’s U.S. powertrain facilities in order to help make more V8 engines. The investments will help increase capacity and increase efficiencies at the Spring Hill and Tonawanda plants. The bigger of the two investments is $40 million for the Spring Hill Global Propulsion Systems plant in Tennessee. GM will spend $40 million to increase capacity at that plant to build more of its 5.3L V8 engines. That engine, combined with dynamic fuel management and a 10-speed automatic is bound for full-size pickups and SUVs like the all-new GMC Yukon revealed earlier this week. Spring Hill builds GM’s 6.2L V8 currently, so this engine would be an expansion of that line. The shop also builds 2.0L turbo engines for Cadillac and the GMC Acadia and the 2.7L four that powers the full-size pickups. The second investment is at GM’s Tonawanda Engine Plant in New York State. The plant will see $4.4 million in capital investments and $2.3 million as part of an effort to improve efficiencies at the facility. The efficiency project is to increase production of the same 5.3L V8 at that plant. Tonawanda also builds GM’s 4.3L V6, the 6.2L V8 including the version used in the Corvette, and the 6.6L HD gas engine.
