In June 2010, new emissions regulations introduced meant that the iconic V8 engine had to be discontinued. Ford phased this out quietly; motoring magazines did not even report on it.

Prodrive specifically developed the engine in Australia to FPV's own standards (read below). A new FPV model, the GS, was released to "plug the hole" between the XR6 Turbo and the higher level (and price) FPV V8 models when the XR8 was phased out. The GS is an entry point to FPV, taking many of the sales that would have been destined for the former Ford XR8.
