I don't understand either. The formula you copied uses Kilowatts, not HP, and includes an artificial increase with CO2 output (obviously to punish cars with bad emissions). They can't be using CV as calculated using that formula, because by plugging in the 789 hp published (converting it to 588.357 kW), the CV calculates out to 73.8 + the C02 term. In order for that to equal 800, the car would have to be putting out over 79 pounds of CO2 per kilometer!

But, let's go the other way. Average CO2 per kilometer in Italy is 118 (thanks, Google!). Let's say the Ferrari is a bit higher, at, I don't know, 140. Plugging that in and working forward gives us a CV of 76.9. Hmm, wait, that seems awful close to 80. Let's work the equation assuming a CV if 80... CO2/km calculates out at 279g. More Google. Ok, looks like Ferrari is averaging 250-300 CO2/km for 2017 models. That checks out.

So... I think we have our answer. The CV is 80, not 800. Still works for the explanation of where the 8 came from.
