After months of speculation... here it is... the sound of the 812 GTS (with GPF fitted) revving! Sent to me by a dealer in Australia that has a demonstrator. I spoke to the salesman and mentioned I’d already ordered one so no need for a sales pitch; what does it honestly sound like? He said the GTS is not quieter than the 812, although it does have more of a deep, baritone sound. He mentioned that most people couldn’t tell the difference between the two, unless they really listened for it. I guess this is good news!! Will be great to hear it in person, but it puts my mind at ease somewhat.
