No. It isn't ever going to be done because it would be hyper expensive.
Corvette's carbon fiber is used to make some body panels. Unlike the Corvette, Camaro is constructed as a steel unibody. Then there's the durability and crash issue (unlike steel and aluminum, carbon fiber shatters and splinters instead of bends and crushes to adsorb inpact).
There's a good reason why there isn't a car manufacturer that uses a 100% carbon fiber construction.

On top of that ditch the seat warmers and whatever else they determine is "unimportant" without going overboard by getting rid of what the MAJORITY of the public expect in cars nowadays (A/C, Pwr Window & Locks, etc).
They could take it even further the same they did on the C5 Z06 "relatively" cheaply by using: titanium exhaust, thinner windshield, and on the '04 Comm. Ed. Z06 a carbon fiber hood (do the same to Camaro's trunk)."
Between the Titanium exhaust and Magnesium engine cradle to it's Aluminum frame, and all the other expensive weight saving items, the Z06 weighs..... drum roll please..... an amazing....47 pounds
less than the standard run of the mill Corvette.
We need to take the time to actually check things out before using them as an example.
The Z06's weight savings was primarily to avoid weight gain related to a more powerful engine and higher performance capabilities If you are going to charge a $25-30,000 premium for this car, you can afford magnesium engine cradles and roof supports, carbon fiber front fender, front wheelhouses, and floor panels (the only carbon fiber parts of the Z06 body
), and pop in aluminum piece instead of steel into the hydroforming machine for the frame. Subtract about 10 grand due to added costs that went to the engine, and there's still a healthy profit.
.....as far as making significantly more power (50hp+) without being blown? Come on guys, get real
.....if it was really that easy to make a "cheap LS7", don't you think GM would have done it already? Do you really think that adding an extra 53hp to the current LS3 is just a matter of throwing a bigger cam in it? The EPA would love that
You hit the nail on the head here.
I suppose you could replace the magnesium parts on the LS7, the sodium filled valves, the extensive use of titanium, loose the dry sump lube system. You'd still have an expensive block (it isn't the same block as any other LS engine), and you'd spend alot of time and money re-engineering pretty much the entire engine since you'd have to replace, test, and certify all those exotic parts (even the pistons are completely different (shorter as well as smaller) than that on the regular LS engines.
A non starter for use on such a relatively small number of vehicles.
That's why GM created the supercharged LSa engine.
Many people have a hard time accepting the notion that if something could be done it would be. That covers everything from a "lightweight" Camaro to "budget" LS7s. GM may be overly conservative, but if there was a way GM could make ANY
car lighter and pass the same rigourous guidelines, of all things GM screws up on, that is one thing they would do 100% religiously. GM will
spend money to take off weight & make things lighter duty to take off weight. But that has to be balenced with current and future safety requirements as well as product liability and being durable enough to stand up to the abuse a performance Camaro owner will or might likely subject their car to.
If you want the Camaro to lose weight, then the only practical and realistic way to do that is to start thinking about the next Camaro with less power & without a V8 engine option
. That way, the body and driveline components can be made lighter and they in turn will make the car substantially lighter.
Thinking you're going to get a 475-500+ horsepower rear drive, IRS, safety standard passing Chevrolet Camaro that isn't the size of a Solstice or doesn't have a top end governed to 155 at a weight notably less than what we ended up in the price ballpark that we ended up with with isn't realistic.
.... and there are people who still have issue with the price increase.
