Ferrari FXX K, Aston Vulcan, Mc Laren P1 GTR, Pagani Zonda R vs GT3 cars

[hondafan37]

I do not get information about the lap times of these super extreme cars and I'm intrigued to know how good they are with respect to GT3 race versions.
This super extreme cars have much more power of the GT3 and Less weight in some cases, but I guess the GT3 have a much more optimized design in terms of aerodynamics, chassis and suspensions.
I have the sensation that the GT3 are much faster in areas of many curves and these super extreme cars are much faster in straight lines.
I would be very grateful if anyone knows about the lap times of these cars in different circuits.

Ok I'm going to do some pretty wide comparisons here, so they won't be accurate but might give us ball park numbers.

The Aston Martin DBR9 lapped Mid Ohio in 2006 with a pole time of 1:18.857.

The K-Pax McLaren lapped Mid Ohio in 2016 with a pole time of 1:19.397

This basically puts the current GT3 cars within half a second of an old GT1 car, on a mixed, short-mid length circuit.

The Ferrari FXX lapped the Top Gear Test Track in 1:10.7

The Aston Martin DBR9 (equivalent to a GT3 car), lapped the Top Gear Test Track in 1:08.6

So if you go by this very very rough comparison, it puts the current GT3 cars around 2 seconds a lap faster than the hypercars. Gap might be smaller given it was an FXX, not an FXX K that lapped the circuit.

BAE Sea Harrier lapped the circuit in 0:32.2

Can we have a Sea Harrier GT3?

Sure, just as long as you're prepared for it to run BoP'ed down to 7.0 m wingspan, 7000 kg dry weight and 70 kN of thrust!

Only if it is BoP'd with a 2006 Ford Fiesta. I want to be able to compete with my car, and it's just not fair if someone else if faster. I also have no reverse gear, so nobody else is allowed to go backwards.

The Koenigsegg One:1 did Spa in 2:32. It might have more in it, but that's easily 10-15 seconds slower than GT3's are capable of, 2:18's and 2:17's for qualifying.

Supercars are much more powerful than GT3 cars, but they have much less downforce.

Would've been on street tires too not slicks which would account for some time but still would be slower then the GT3.

Thank you all for the answers.
Here I found something in the Ferrari chat.
http://www.ferrarichat.com/forum/288...s-fiorano.html
ChalStrad in the forum said:
"An XX is a laboratory. It is an experimental car that is also designed for the gentleman driver to exploit. It is no mean feat to put almost 1100 horsepower into the hands of a non professional and put a smile of the driver.
The 488 GT3 is a pure racing car where no concessions are given to anything other than performance.
Power is not everything. Aerodynamics are crucial and the 488 GT3 is an aerodynamic masterpiece"
A 488 is quicker around Vallelunga than a FXXK by about 1 to 1,5 seconds (depending on the BoP the 488 has and, of course, the driver).
It is fair to say that the FXX K (and even the older FXX) annihilates a GT3 racer on the straights and then gets spanked in the twisties.
For example at the end of the straight at mugello I brake 100m earlier in the K than in the F1 and yet at that point I am 8km/h faster in the K notwithstanding the slower exit from the parabolica. Yet, I am 24 seconds / lap faster in the F1 car.
What is important is to compare the comparable."

According With Top Gear, the Aston Vulcan was three seconds per lap faster than Aston’s GT3 racer in Snetterton and is nine seconds faster than a McLaren P1 road car in Nardo.

I've read somewhere some time ago that mclaren p1 ran in 2.38 at spa.
Is clear that street hypercar have a huge amount of brute power, but basically lack of anything else. Are heavier, have a worse mass distribution and generate much less downforce (that helps more to keep the car stable at insane high speeds on straight than increase corner speed). That's explained the 20s difference in a fast track like spa.

Not to mention that GT3 cars have racing slick, street cars not (or at least is not the prime compound)

[TF110]

Aston should be running the Vulcan in gte. Too bad we don't get to see these types of cars run races. True beasts.

Very good contribution, but you have to consider that the P1 road car is very different from the P1 GTR

[canaglia]

Actually, never liked P1 GTR, but at example I know that laferrari fxx k has an improved kers that gives more power to the car, a different suspensions geometry and has a revised aero that let the car have a lower cx even if developing a little more downforce. Guess is lighter too.

Anyway not enough to achieve the same corner speed of GTLM and GT3 cars... just to say, GTLM and GT3 can run through eau rouge almost flat out at 200km/h, these kind of hyper cars won't never be able.

Yes of course, the Vulcan should be the GTE, it is a more extreme car than the DB11 or the new Vantage, more at the lever of the mid-engine opponents cars

Well, the first season of "The Grand Tour" is out and they tested the Porsche 918, the McLaren P1 and the LaFerrari at Portimao. They got Jerome D'Ambrosio to do the timed laps and hist times were around 1.54 - 1.55.

GT3s were 10 seconds faster than that at last year's Blancpain Sprint round.

[Starfish Primer]

How those times compare to GT4 cars?

Hard time finding anything for that - don't think the official GT4 series ever went to Portimao, but Portuguese GT (RIP) did and there was an Aston GT4 running in 2013. Now we don't know how close to full GT4 spec that one was (it ran in a class with a Porsche 997 Cup and a Ferrari 430), but that did a 1.58 in qualifying. So slightly slower than the hypercars.

Edit: With TCR slightly faster than GT4, that one should be right in the mix. Would be a hoot if one of the three Grand Tour hosts showed up with a Seat Leon TCR to one of those supercar comparos.

And another note on the Grand Tour laps. They ran all cars on the same (road legal) tire, with Clarkson claiming that the McLaren could have gone a lot faster on its original tires. So it's reasonable to asume that fitting proper racing slicks probably would have closed the gap by a considerable degree as well,.

Ver good information, but sure there is some difference between Laferrari and the P1 road car with their respective extreme versions the FXXK and the P1 GTR

The P1 is almost 2 seconds faster on the Pirelli Trofeo R tire around Portimao than it is on the Pirelli Corsa tire.

One thing to note is that the TGT laps were standing start laps, while racing/qualifying laps in GT3, GT4 and the Harris laps have flying starts.

Who's to say aston won't be running a Vulcan GTE in 2018?

I was in the Aston Martin pits this year at Silverstone and i asked one of the team about the new car. He smiled and didn't comment when I said is it based around the Vulcan platform.

Great, I love the Vulcan.
It's good to see more extreme cars in GTE.
What will happen to the engine?
The V12 7.0 is out of rules but the Viper was allowed by the ACO in the past.

[TF110]

I thought the sub 5.5L engine size rule was abolished?
