Chrysler has said they are having trouble coming up with a v6 Challenger that can be priced within $5K of the V6 Mustang. Chevrolet has the same issue and is considering not even offering a V6 Camaro.
You may be wondering why that matters, since most of us would only consider the R/T or Z28 version anyhow. But the fact of the matter is that the Camaro/Firebird were cancelled because they could not sell enough V6s to make the V8s profitable. Ford sells 5+ V6 mustangs for every V8. Some say they barely break even on a V8 sale, so without the volume and profit from the V6 versions these cars (pony cars, where big V8s are stuffed into cheap 2-door bodies) are doomed, at least for the long term.
I do like that Challenger, but I wonder how much different the production Camaro will be from the prototype. I know it wont look like that though, hopefully they wont detune the design too much, becuase it does look nice if perhaps a little "busy".
