I was timing F80's last Goodwood run from today, and it did about 0:49s with huge burnout off the line.
I think if Ferrari wanted, they could have broken Koenigsegg's fresh production car record quite easily.
Yeah, I do agree with your statement.
As a further proof, I roughly timed another run of the F80 at mid-to-low 48 seconds,
with a passenger.
Here below I report a link for direct visual comparison between the F80 run with passenger and the record run of the Sadair's Spear.
Videos are buffered to start at the same time once both cars launch.
F80 vs Sadair's Spear
The Sadair's Spear run was mighty impressive, car is fantastic and I have huge lot of respect for Koenigsegg being able - as a relatively small team - to build such performance machine all in-house, while still retaining all creature conforts.
Also, the most impressive feature of the Spear is its capability to put that huge power down just on its rear wheels, and not for mere (and I would say also useless) straight line speed, but for real handling and track performance. Given its aero, that car requires a very rigid platform (between chassis and suspensions) to cope with the loads at high speeds, yet it demonstrated excellent low-speed mechanical grip in its Goodwood run.
It is not easy at all to combine these two requirements, so this is a proof how good latest iterations of Koenigsegg Triplex suspensions have become.
Being said that, it appears to me that the F80 is still a step ahead.
The Koenigsegg platform still slightly squats and dives during acceleration and braking, while the F80 is running completely race car-like flat, like a magic carpet.
Those active suspensions are simply a game changer and they are just ahead of anything employed on road legal cars until now.
They can instantaneously imprint active forces into the system at each wheel corner, cancelling out effects due to body mass transfer and inertia.
Already on the Purosangue, they make the car behave like it is 300+ kg lighter, imagine them evolved and applied to a 499P-inspired carbon chassis with already an absurdly low center of mass (just look how low the engine in the F80 sits, for example).
More in general, the whole package (chassis + active suspensions + active aero + E-turbos + MGU-H/K + Challenge race car brakes) is just really, really good.
And what appears to be most impressive to me it's performance repeatability on track, which is quite often not a given for road legal hypercars.
I wouldn't even say that it sounds bad. It's just quieter than 296 because of senseless bureaucrats.
Not only because of that, but this is also due to the employment in the F80 of MGU-H units, which (coupled with the E-turbos) generate active power by harvesting the kinetic energy in excess released by the expansion process in the turbines.
So, exhaust gases do possess less energy upon their release in atmosphere, fact which contributes to the overall muffled effect.
Clearly the 296, with conventional turbos, is not affected by this phenomenon.
This is the same which happens with modern 1.6 L, V6 turbo F1 units which are quieter than turbo engines from the 80s, for example.
BTW, let me just tell you that I agree with everything you wrote in these last 2-3 pages. The F80 is just a monster, top tier technical stuff.
