Camaro has been more
Camaro has been more expensive than Mustang for much of its existence, so why anyone would expect it will be less with the release of the best Camaro ever(by very, very far)... beyond me.
The 6th gen is more expensive to create and more expensive to build, according to many "online accolades" about how great it is. We know for sure, the engine costs more in the SS, thanks to DI. It's also some 37-47 lb heavier, which leads some to wonder if the "200 lb less" weight will be seen on real scales. Updates to the V6 didn't likely affect pricing noticeably. The turbo 4 is a base engine in other cars too, so it's likely not a big drain in terms of cost and that makes it rather smart to use it as base, even though the V6 is also base or otherwise used in other cars(many, many others). As mentioned, placing the 4 at base can allow for a price bump in the others, but that should be fully expected anyway, considering just the hype GM has been laying on the 6th gen.
Anyway, the car costs the most ever to produce. I expect increases of about $2,000 for the base V6 and V8 models. That could allow the 4cyl turbo car to sell at the current pricing. Barring a price increase though, GM is almost certain to lose money on Camaro and that's not acceptable.
Since it's fully expected(in V8 at least) to out-perform Mustang GT, I don't see any concern in a 2k increase. I don't think it will sell like the Mustang, regardless.
