Undoubtedly the British press are protective of McLaren but at the same time no McLaren has ever won a significant test against a Ferrari in any of the British magazines. Both CAR and Top Gear picked the Laferrari over the P1 and Evo picked the 918 over the P1. Speaking of which it looks as though Road and Track have also picked the Laferrari over the P1 in their forthcoming test. Makes it 6-0 by my count.
Actually it doesn't work like that. More mass is always a hindrance as the centrifugal forces of the weight overcome the grip of the tyre. There are mathematical types that show how the grip level of a given tyre is reduced for every kilo of weight added to the mass of the vehicle. Downforce on the other hand puts pressure on the tyres without adding mass to the car!
Quoted acceleration figures for the One:1 are 'quite quick' 0-400 km/h (250 mph) in 20 seconds. Roughly the same as the 918 for 0-300 km/h (186 mph) From the article Koenigsegg are looking to put a ring time down.

It's not that simple. The location of the mass also makes a difference. Higher location means there will be a higher rolling force to rotate the tire outwards and peels off the contact patch, reducing the contact patch size, especially if that CG is higher than the centre line of the wheel. Conversely, if the CG, i.e. roll centre of the car is below the centreline of the wheel, which the 918 has, the outward rotational force is greatly reduced and preserving the contact patch. Tire grip only goes away with the addition of weight past a certain threshold, i.e. the tire's limitation. Before that, the more weight/downward force that can be apply to a wheel, the more grip it will have. Tires cannot tell whether a vertical load is from physical mass or aero load, it only knows it likes vertical pressure. But in simple terms, yes additional mass will be a hinderance, and the 918 has the electronics to help it over come or minimize that.

End of tire debate: http://youtu.be/rrLQpAt5Mes Standard Trofeo R is 2 seconds faster than a "bespoke" MPSC2 tire on the 991 GT3.
I did tell you all the trofeo r was much stickier than the cup 2 ( especially the 918 version ) but it can do less laps . Old Doomy doesn't lie , I call it like it is , 2 seconds on a two minute lap IS HUGE .
And extrapolate that results to the Anglessey test from EVO on the P1 vs 918 laps, that means the 918 can expect to gain 1.4 secs on a lap there too and that puts in ahead again by 0.2 seconds. Corsas and Cup2s are the same level tires, Trofeo R is on another level.
There was a lot more time to come off at anglesea anyway Boring don said that with time and adjusting pressures there was a load to come off anyway No it reflects the other tests we have seen Porsche guys laughed at the video " we can only win a test we are invited to " was the reply I got Hilarious
On another day with different tyres and Porsche weren't invited back . "The fastest car at any track at any time " Ron needs a wig I think lol
If anyone has watched Chris's new 42 min video, could anyone tell if he changed his opinion of the 918? Because it looked like he did to me and I'm not complaining.
Wonder why McLaren made up some excuse and chicken out on Chris Harris' video. If they are that confident with their P1, they should have no problem showcasing the car.
The Peleton myth. LOL The factory 2 piece roof is already super light, at most the one piece roof on the prototype would shave a couple lbs. Not enough to offset the timing equipments. Actually come to think of it, I think it's because McLaren can't do a best sector time combined for the Chris Harris video so they declined.
I think someone already said that the fixed roof is actually heavier than the two panels. I'm just not sure who though.
Somebody who went to the museum and saw the car told me that the whole cars panels seemed to be lighter than production spec. It makes sense i mean when you try and set a production car lap record extreme measures are taken. And hey, its the n-ring. The rules are no rules
So what was the P1's ring time again? 6.3x wasn't it? P1 owners/fanbois trying to undermine the 6.57 time just reek of desperation. If anything, the final production spec 918 would be quicker than the 6.57 car as you should well know.
