More "purosangue" news!
- The car may only be offered with the V12 for its entire production run
- The car will go electric only after 2-3 years of production
- The car may have rear hinged suicide doors
- As stated before, the car will most likely not carry the name Purosangue

Can someone tell me since when has the Ferrari 812 Comptizione became a "$1 million DOLLAR" supercar? Atleast accordingly to Topaz UK?

Note: Transmission gear ratios are borrowed from Ferrari 458 series. Yes, the F12 and 812 all share the same ratios as the 458; the final drive ratio is claimed to be "shorter" in the 812, so I used 5.14 as claimed for the 458 instead of 4.38 as claimed for the F12.
Unlike its Lamborghini and Pagani competitors, I used a rolling coefficient figure of 0.080 (instead of 0.050 in the Aventador SVJ Coupe and Huayra Roadster BC) because the initial top speed figure was far too high. Even at 0.080 it was still going slightly faster than the claimed top speed of 340km/h.
I really wanted to add a secret: Ferrari's claimed curb weights are race weight figures, meaning that while it's not technically a dry weight figure, those 1592 kilograms are mythical because they alone do not take any gallons of gas into account. 92 liters of petrol = 24.304 gallons of gas! Ferrari does not lie about curb weight or acceleration numbers, but they are very optimistic with those figures.
https://www.thecalculatorsite.com/conversions/common/gallons-pounds.php
149.528 pounds is needed in the US, but only that number multiplied by 0.90 is needed in Europe in order to compensate for the actual curb weight figure. 134.5752 pounds, or roughly 61 kilograms for the European market; 1592+61 = 1653/1728kg (DIN/EEC standards).
Downforce adds 290kg, so 1653+290 = 1943.
As far as acceleration figures go, the simulation is off by roughly 0.2-0.3s for 0-100km/h and a whopping 0.6s off for 0-200km/h. But it's not the simulator's fault. If you're an American (or whatever) and you take rollout into account (like most Americans do), you might see something like 2.8s to 100km/h and 7.8s to 200km/h. That's about it.
A manufacturer's press car is still going to have a hard time bettering 3.1s to 100km/h because it's a front-engine, rear-drive car and not a mid- or rear-engine, and/or an all-wheel-drive one. Still, with the quarter-second rollout one could expect 2.84s to 100km/h and 7.57s to 200km/h; that's actually very close to the press car's claims of 2.85 and 7.5. That car will need 22.2s to reach 300km/h, and the top speed is 359.9770km/h (or 223.6793mph). That is almost significantly faster than the private customer owned variants.

@FastestLaps: Please add curb weight:
812C: 1487 kg = 3278 lb
812SF: 1525 kg = 3362 lb
Ferrari also published curb weight for 812SF which is 1630 kg (3594 lb).
812 Competizione curb weight:
3362-3278 = 3594-84 = 3510 lb curb weight
1525-1487 = 1630-38 = 1592 kg kerb weight
Compare these two:

Another source is saying 1592 kg:
https://www.guideautoweb.com/en/makes/ferrari/812/2022/specifications/competizione/
Ferrari even mentioned on their own site that the 812C overall weighs 38kg less than the 812SF: https://corporate.ferrari.com/en/812-competizione-and-812-competizione-two-interpretations-ferraris-racing-soul
