well, these (686hp) are based on the assumption that the "turbo S" will keep the exact same engine as the turbo (550hp), and thinking that the Turbo S will be an hybrid, i.e.: by adding the exact same 136hp electric engine of the current model.
Frankly, ..this looks like "old tech", or IMO, not really what could happen !
About these V8, let's also remember that the Audi 4 liter of the 2017 S8 Plus, without any electric help, provide 605hp.
And about ?plugin? hybrid, lets keep in mind that Porsche (I should really say Alexander Hitzinger) invented a new way to permanently load batteries, ..i.e.: with secondary turbos, transforming the residual pressure of the exhaust, (after the primary turbos,) to run generator that loads the batteries. This has been used on the 919 (since the beginning of this "model") ..with quite good successes already.
I can only suppose that this very innovative technology, that enable even better engine efficiency (and lower CO2 emissions), will be used quite soon in production on high end models.
