The GM Tonawanda Engine Plant located in upstate New York is responsible for the production of a quite a few GM powerplants, including the renown LT1 V8 found under the hood of the Chevrolet C7 Corvette Stingray and 2016 Chevrolet Camaro SS.
The Tonawanda plant puts out around 1,500 LT1 units per day. It also produces the 2.0 and 2.5 Ecotec four cylinder motors for the Buick Regal, Cadillac ATS and CTS, Chevrolet Malibu and Chevrolet Impala. The metal casting goodness doesn’t stop there, the plant also creates and assembles the components of the 4.3L V6, 5.3L V8, and 6.2L V8 EcoTec3 engines, which eventually end up under the hoods of the Chevrolet Silverado, Chevrolet Tahoe, Chevrolet Suburban, Cadillac Escalade, GMC Sierra, and GMC Yukon and Yukon Denali.
Last, and certainly not least, is the LT4 V8 which powers the Cadillac CTS-V and Chevrolet Corvette Z06. While the LT1 made Ward’s Automotive 10 Best Engine List for the past two years, the supercharged LT4 has been getting grief from unsatisfied owners. That said, it would still be our first choice if we were to have our pick at test driving any of these powertrains.
