Rumors circling of them not being able to fully crack a Sub-7 laptime on Nords.
7:04 is what is being rumored right now. Maybe this is why it´s not official yet.

If they break a sub 7 time it will be as quick as Ferrari´s own prototype racing machine 599XX.
And that´s with no slicks. Quite impressive machine the P1.

Has the P1 just clocked the ring in 6.47?

God I hope so!

If true, 10 seconds quicker then the Porsche around there.
I think the relative gap will be even larger on flat GP-style circuits.

Reminds me to the 6:47 Pagani Zonda R lap, on slicks... that´s pretty remarkable.

Maybe also a new rubber mix from Pirelli?

Hopefully McLaren will publish it officially

Apparently Chris Goodwin will be unveiling the P1 at the Dubai motor show next week, seems like the perfect time for a special announcement me thinks ;-)

If you read the article you´ll know that it´s not a real time. Mclaren have responded to that.
The image in question was included on a slide which was part of a mood board to inspire the design team for the McLaren P1™, and not the engineers, who are working to a target time of ‘merely’ sub-7 minutes.
Image
People who were at the track recorded first a 7:04, then days later some claimed it pulled a 6:47.
We´ll have to wait on an official quote to know for sure how fast it really went.

-
This is quite impressive, 903 horsepower, performance like something out of this world and yet, about the same fuel economy as my ex 320i E46 lol.
Despite these impressive figures, the McLaren P1™ still returns 34.0 mpg (8.3 l/100km) on the EU combined cycle, with CO2 emissions of 194 g/km.

P1 is P1 in Jeremy Clarkson's personal car chart. This month at TopGear he drives it around Spa. I think this is a world-wide feature.

Here is an interesting article on all this Nürburgring talk. And I agree its all pointless and mean squat because of all the variable etc. "Captain Slow approves this message" :D

Sad to read the rumor McLaren don´t like to join the game. I would absolutely respect this if it would be a convincing attitude, but then warping a 6:33 on a wall is just silly! More then ever after so much testing at this track and talking about the P1s incredible track performance. Maybe they got the time out of the simulator?

I usually like McLaren because they talking about engineering, not emotions. I think engineering has enough emotions by itself. But with the P1 they start to confuse me. Another thing that irritates me and is well in the line with this 6:33, is the 2.8 seconds from 0-62 mph. Where should that come from? It is rear wheel drive and has a pretty low center of gravity. From the engineering point of view, it would be a miracle if the P1 would beat a GTR in that task, and if so, we can applaud the tire manufacture. With such numbers they just can loose. Don´t starting with the 600 kg downforce just from the rear spoiler. Not worth the paper it is written on.

Anyhow I like the P1 more than porsches 918 spyder by several reasons. But the politics from McLaren I don´t like. They really barking a lot about performance, so if they don´t deliver some convincing numbers I get bored.

I think they use the electric motor to help the initial movement in launch. The electric motor is relatively weak (compared to the IC engine, at least) so the tyres can take all it has to give before the IC gets up to speed. This means they get moving with minimal wheelspin and thus they maximise traction. The result is the same as a heavy 4WD system and thus why they can get such a quick 0-60 time.

A number of reports of how responsive the car is to the throttle, even though it's a high performance turbo-charged engine, suggest that the elctric motor is used to "fill in" for any gaps in the IC's output. That's why I think they use it during launch too.

So it doesn´t matter if they are true or not, they just need to be convincing...to you?

There´s plenty of cars (RWD cars) that can hit 100km/h below 3 seconds.
From Agera R to Ariel Atom V8 (which has the record)

It´s like you don´t believe it, but if you do, the tire company should be applauded but ultimately you say they lose anyways.
What?

Okay, I have to admit my criticism is also a bit emotional

But If you look your wiki link closely it defends my statement. To get a nice 0-62 time you need AWD or in case of the Atom RW combined with a CG near the powered wheels. Like a drag racer is designed.

In direct comparison you can see my criticism this way. With the GTR you get the factory number pretty easy. Getting a car with RW drive under 3 seconds is a challenge and mostly a theoretical value.

And explaining my harsh rear wing comment: Estimating the size and lift coefficient by comparing it with known performances of such wings, you can be pretty sure the 600 kg (kg isn´t a force by the way) value will just be reached close of the cars top speed. And the top speed can´t get reached with a raised wing. But this also is based on assumption, so I shut up.

Don´t understand me wrong, I really like the P1 and I´m looking forward to see it at top gear etc. When Mr. Clarkson is so much in love with it, it must be awesome. But especially when Porsche just published a real 6:57 and McLaren showing a 6:33, they gambling credits. Just my 2 cents.

A last note on the NS record time.
To me this record is one of last holy grails in motorsport in terms of engineering and design. Racing cars nowadays are highly limited and politics are a big issue. The NS record is a bit of wild west mentality. The rules are wide open when you are a manufacture, but you also have to face all the risks. If a driver gets killed, you can´t point at the FIA asking for help. This makes it more complex and thats because I respect this record so much. And thats probably why I´m in charge when McLaren don´t respect this record by putting such a time on a wall ;)
