What is it?
There wasn’t a great deal Ford Performance could do about the Mustang’s size, but to give the Shelby GT350R a fighting chance on track, it ditched the rear seats, stereo, sat-nav and air conditioning (although the latter three items can be added back in optionally). The wheels are exotic carbon fibre items, too, saving 6kg at each corner. The total weight loss over the 5.0 GT is 60kg, which is useful if not exactly transformative.
The entire chassis has been overhauled with uprated components and a much more track-focussed set-up, while a comprehensive aerodynamic package promises much more downforce than the regular car.
Most unusually, though, the warbling V8 engine that powers the conventional Mustang has been ditched for a high-revving 5.2-litre flat-plane crank V8. That’s something of a departure for an American muscle car; flat-plane cranks and high-revving V8s have been the preserve of European sports cars until now.
