Camaro will continue to 2026?
This is based on the likelihood that an Australian based unit has been given permission to continue a 2nd stage manufacture operation through 2026. Second stage manufacture is where a car company ships vehicles to a separate unit or company that then makes significant modifications before selling the car into commerce. Callaway is an example of a second stage manufacturer. GMSV is sort of an "in-house" second stage manufacturer. Since GMSV expects to sell about 500/yr right hand drive Camaro SS vehicles, the most likely scenario is that GM will simply build out 1,500 - 2,000 vehicles at the end of Camaro's run in 2023 to be set aside for GMSV to modify and supply the cars to the Australian market through 2026. Absolutely no need to keep an assembly plant open to fulfill GMSV product needs. That would be a serious example of tail wags dog. And GM is also not gonna decide "well, since Australia wants 500 cars a year, maybe we'll keep LGR cranking out low numbers of Camaro for North America to make it possible for Australia to sell their 500/year". Again, tail wags dog. Keep in mind that in about this same time, Cadillac will be replacing CT4 and CT5 with BEVs, so Camaro will be the only product on an Alpha platform. That won't float.
