Thank you so much for posting this!!!
Now.....if the doubters get it.... I'm good! lol.
(we used to build up to 5 different models....on the same line / at the same time. They still do about 3 or 4 in oakville).
Bowling Green Assembly is a specialized plant. There have been rumours of (a new) Caddilac sharing the space....but rumours are just that, and for now, it's a 1 horse town.
Currently there are 4 different models being built at the Ford plant in Oakville: Ford Edge, Ford Flex, Lincoln MKX, Lincoln MKT.
The Ford Edge and Lincoln MKX is the same vehicle, so super easy to build on the same line.
The Ford Flex and Lincoln MKT are also the same vehicle.
Oshawa (RIP) also built the Camaro alongside the Impala, but they were actually on different lines in the same facility. There's a fixed line where they churned out high volumes of one vehicle and a flex line that ran slower but could build multiple vehicles that weren't in such high demand.
It's not uncommon for one plant to build multiple similar vehicles at once, but it's uncommon to build two completely different vehicles on one line. The entire system is custom-made for one specific vehicle and every small change can make a drastic impact on overall productivity. The automotive industry is all about JIT and Lean/SixSigma. That's why you usually see one vehicle from one plant.
Yes, it does happen in the rare occurence with the C8 mixed in with the C7, but that was a test and wasn't a production run. It likely would have slowed the line way down as everything for the C8 was bespoke while the C7 was in production.
IMO, the argument isn't really whether or not it has happened, or could happen, but that the photo was clearly a fake, so why are we having this debate?
