Us Aussies know how to design a car
Its called a Monaro over here (long history as an Aussie sports car), they're the talk of the industry since they came out.
If anyone wants to see/read about the Aussie version, have a look at
www.hsv.com.au or
www.holden.com.au. I think they'll have a 300kw engine in them....not sure what that is in hp. The Australian Monaro GTS has that engine, so I think the American GTO is also getting it. If not, you'll probably get the 255kw LS1.
