Using my own formula, here's my calculated or projected top speed of the fastest car, Koenigsegg Jesko Absolut, based on these parameters and conditions. Not knowing the actual powertrain loss, I can only work in reverse, like reverse engineering it, tie and match the horsepower loss to the other parameters. Solving S directly is not possible since it's not possible to isolate S or speed in the equation. One work around is to rearrange the formula and iterate to solve for S.

Air density or rho = 1.225 kg/m^3; 0.076474 lb/ft^3; 0.0023769 slug/ft^3 -> 59 F; 29.92 inHg; dry air or 0% humidity

S = Top speed (calculated) in mph
H = Horsepower (crank or Bhp)
Wt = Weight (Total) of car, driver and downforce, if any, in lbs (Wc + Wd + Df)
Wc = Weight of car in lbs
Wd = Weight of driver in lbs
Df = Downforce in lbs
Pl = Powertrain loss in decimal form -> 09% = 0.09; 10% = 0.10; 11% = 0.11; 12% = 0.12
Af = Frontal area in sq ft
Cd = Coefficient of drag
Cr = Coefficient of rolling resistance

H = [0.0025565AfCdS^3 + CrS(Wc + Wd + Df)]/[375(1 - pl)]

H = 1,600
S = 331.65 @9% Pl; 330.40 @10% Pl; 329.14 @11% Pl; 327,87 @12% Pl
Wt = 3,561 -> Wc = 3,065; Wd = 165; Df = 331
Pl = 9%, 10%, 11%, 12%
Af = 20.24 sq ft
Cd = 0.278
Cr = 0.018

Here’s the math and equations explained and done:

Apparently the Jesko Absolut has a drag coefficient of 0.278 and only 40 kgs of downforce at 150 mph so in theory it has the potential to do 330 mph? I'll believe it when i see it but all that it would take is a sudden gust of wind and you're history...

Bugatti and Koenigsegg aim 300mph like Ferrari and Ruf aimed 200.. hehe

Ferrari aim for driving pleasure more than anything. Top speed is not as sought for as ‘ring records

First of all, Ferrari’s aim is to make as much profit as possible, it’s aim is to satisfy its shareholders.
Top speed isn’t as sought after as ring records? What ring record has Ferrari gone after? And I don’t know if anyone who would prefer a new Ferrari over a new koenigsegg.

If driving pleasure was so important to Ferrari, they should have kept a gated shifter in at least one of their cars.

Don’t get me wrong, they are still the most exciting main stream brand. But even they classify themselves as a luxury goods maker and not a car manufacturer anymore.

This is the streamlined top speed version. Koenigsegg is claiming 330 MPH. Specs are based off running on E85, feel free to change to gas.
