Yea what exactly is the difference between the 510 bhp GT S and the 462 bhp GT?
Yea, BOOST, that's all... (in terms of motor)
The turbo V8 might only be four litres, but it's immensely charismatic, and makes 510bhp in the S model. (The 'basic' GT, on sale six months later, is 462bhp, only because of lower boost.)
Sure, there's noticeable lag below about 3500rpm, and the revs run out at a disappointingly moderate (but par for a turbo) 7000rpm. In between those two, though, you've got an engine that answers the accelerator with quick and epic force.
