Bowling Green is about to take three long coffee breaks, and Corvette fans will feel every one of them. Chevrolet’s Corvette assembly plant in Kentucky is scheduled to stop production for three separate weeks because of supplier-related parts issues. The shutdowns are set for April 27 to May 1, May 4 to May 8, and June 1 to June 5. GM sources had already pegged May 29 as the end of 2026 Corvette production, but the company had not formally locked in June 1 as the start of regular 2027 production. That left a gap, and now the gap has a name: three shutdown weeks. Bowling Green Is GM’s Performance Cathedral ChevroletBowling Green turns out the Stingray, Z06, E-Ray, and ZR1, while its in-house Performance Build Center hand-builds low-volume high-performance engines. On top of that, GM’s Brownstown facility supplies the battery packs and electric drive hardware for the E-Ray. One missing part can now trip up a much more complicated Corvette lineup than the factory had to manage a few years ago.Overall, 2025 model-year production totaled 25,835 cars, but just 180 of those were ZR1s, including pre-production units. U.S. Corvette sales also dropped to 24,533 in 2025 from 33,330 in 2024. First-quarter 2026 deliveries slipped again to 6,235, down 8.2 percent from the same period a year earlier. When rare trims already arrive in tiny numbers, three lost weeks do not look small.The Corvette production has been running a little less like a Swiss watch and a little more like a weekend project car. Last summer, we warned that some 2025 Corvette ZR1 orders could slide into the 2026 model year because of production delays. Bowling Green already faced an unusual production calendar in 2025, when reports pointed to four shutdown weeks spread across late winter and spring. Corvette buyers have had to live with more stop-and-go scheduling than they would like. Nobody orders a mid-engine sports car for the thrill of waiting. When Are 2027 Corvettes Coming? ChevroletEarly June usually looks like fresh model-year territory, yet that is one of the weeks the plant now plans to sit still. CorvetteBlogger also noted that Chevrolet had not formally told dealers that June 1 would mark 2027 start of regular production. That leaves room for a later launch, a staggered rollout, or both. High-volume trims may get priority first, while the exotic stuff waits its turn. On a side note, National Corvette Museum plant tours are currently paused, with additional 2026 dates still unannounced. So even the usual crowd of curious Corvette diehards cannot peek behind the curtain right now.
