Note: GM doesn't do a RHD version of Camaro, like Ford does w/Mustang (as it relates to UK article/topic here).
Agreed, but that was part of my point....one can only wonder how the Camaro SS would have fared if they
DID. That ATS-V chassis is getting quite a reputation.
Back to the article, I have to agree with a couple of the previous posters that, for some things, at least, there's no replacement for displacement. Turbos and superchargers, of course, can add HP/torque to small-displacement engines, but introduce complexity and a number of (potential) problems and issues as well.
