450 hp in the base C7 is pretty expected. The current C6 has 430, the Z06 has 505, and the ZR1 has 650 hp. Going by current trends the C7 Z06 will probably have 550 hp (same as a 458 Italia), and the ZR1 will probably have over 700 hp, stealing the American hp title back from Ford, until Dodge builds an 800 hp ACR.
Agreed.
I'm going to spitball a thought though.
The more important question is going to be what kind of mid-model update will the C7 get when the new Mustang launches. I'm not a Ford fan, but objectively, Ford really took the gloves off with the 2011 update to the Mustang. The next-generation Mustang is rumored to get an IRS, a substantial reduction in curb weight (100+lb at least), and possibly a DI update to the Coyote. For the first time since pretty much ever, it looks like the next-gen GT
might become a legitimate threat to the Corvette. That's speculation of course, and it probably won't actually
beat the Corvette, but it could become close enough to make buyers question the price/performance difference between the two cars. And something like the Boss could actually step on toes.
The next-gen Alpha platform Camaro will see similar improvements, so I think the "pony" cars are going to be in a very interesting position vis-a-vis the Vette in a few years. The fact that both GM and Ford are considering optional twin-turbo V6's for the next Camaro/Mustang will make things even more interesting to the warranty-indifferent tuner market. Indeed, I think GM could be thrust into an uncomfortable place with the next Camaro. If Ford
really delivers on the Mustang, the Camaro that can match it will be perilously close to cannibalizing Corvette marketshare; even to the point where differentiating the Camaro SS and base Corvette motor may become a necessity.
It's going to be interesting to watch, that's for sure.
