It was back on January 31st that we ran a video from our friend Rick Corvette Conti who suggested that there will be some sort of changes coming to the Corvette Assembly Plant. Rick believes that with the addition of the upcoming ZR1 and the rumored Grand Sport that the plant will undergo some changes that would help prioritize widebody production over the current base Stingray which is still the most produced model in the line-up.
Here something that Rick stated in that video that makes a whole lot of sense:
I’ve heard from several different sources so we’re getting it on a very good strong rumor that internally at Bowling Green Assembly right now they’re working on reconfiguring the line. So, what do I mean by that? Right now, and I don’t know the exact mix, so I don’t want to say a number and be off, but before it used to be like every seven cars there was a widebody car. And they told us up front that widebody cars…Z06s at the time only were being made that they slow up the line for overall production. A convertible slows the line, a car with front lift slows the line, but they’re trying to reconfigure this line. There may or may not be a plant shutdown so they can actually put more of those stations together to make more widebody cars.”
Rick has been talking about the rumored Grand Sport for a couple of years now, and he believes that such a car would be the C8’s sweet spot and would replace the Stingray as the most produced model of the C8s moving forward.

Now, just three weeks later after the video, we have it on very good authority that the Corvette Assembly Plant in Bowling Green is scheduling four weeks of shutdowns that will begin as soon as next week. This news has been confirmed by our friends at the MidEngineCorvetteForum.com so it looks like this is going to happen.
The dates for the shutdowns are as follows:
• February 24 – February 28
• March 17 – March 21
• March 24 – March 28
• May 19 – May 23
John at MECF was able to verify those dates, and when asked if this was simply for Inventory Control (ie, letting the market absorb those additional units), he says that’s a great first reason, but there is actually more to it:
Second: There are many BGA employees retiring (buy-outs from the 15 month ago UAW contract), and GM will be reducing the line hourly production rate but not replacing most of them, instead adding additional work station time for each employee to do more tasks. EXTENSIVE re-training will take place. After each retraining for every new/additional tasks, employees, as is SOP, will be given testing to confirm “level four” (top) competence. No one will do any new task until they have completely mastered it.
Thirdly, there are some 2026 Plant physical changes occurring — but not too many nor too big;
Fourth: New 2026 C8 model component changes (other than the ZR1 of course).
Chevrolet has stated that ZR1 production starts in 2nd Quarter so it appears that most of these closure dates are seeming to align with the rumor. We’ve also been hearing that the first retail ZR1s could start as soon as mid-April which would be great news as well. As for the rumored Grand Sport, some are saying the 2026 model year would be the time to do it so that it coincides to the rumored changes to the interior. We’ll wait and see, but so far everything is aligning as it should.
