Based on the presentation, Ferrari isn't holding anything back. The 488 GTO (or "Sport Special Series") will be lighter, faster and more powerful than the GTB. But let's compare what we think it'll be like to, say, the 812 Superfast, which has around 790 hp. The 488 GTO presentation clearly says over 700 hp and, when combined with various weight reductions (the engine alone is 10% lighter than the V8 in the GTB), we're looking at a supercar that could very well have a greater power-to-weight ratio than Ferrari's current front-engined V12 flagship. Even the 458 Speciale will seem rather tame all of a sudden. The 488 GTO will also be very slippery - a whole 20% increase in aero efficiency over the 488 GTB.
