p1 is the better looking one for sure

 

With so much hype and money invested in the P1 and the LF, I bet in the future there will be much dirty PR coming up.

Both of them developed their cars to be on top for years. Nobody wants to "lose" when it comes to track times. So I think this War will produce some nasty news in the car industry.


Are there some informations about when McLaren think to drive at the Nordschleife and Top Gear?

I think on the Top gear track, the LF will be in front, because there are a lot of straights on the TG track.

But at the Nordschleife I can imagine the P1 will be faster, I dont know I'm not an engineer or something, but it's just an initial feeling that makes me think the McLaren produces more Downforce and will be faster around corners than the LF.

So as everybody know curb weight is with all liquids etc, but whats with the fuel tank? Is the McLaren 1400kg with full fuel tank or is there some playground about the definition of curb weight? And how much we can expect the LF's curb weight will be? Will it come close to 1400kg?

Just curious. In Europe when a car manufacturer reports his car is, for example, 1600kg curb weight, then it means with a average driver of ca. 75kg and the tank full up to 70%.
There was an EU standard which has every car manufacturer to follow when it comes to official specs about their car weights.

I red this some years ago, but I'm not sure if its up to date.

 

From my understanding the absolute minimum curb weight would include all necessary components/liquids for vehicle operation. As far as the 75kg for the driver, it should be added really, but isn't always included in the curb weight. Although every EU automaker is supposed to include it. I'm not sure how Ferrari or McLaren weigh their cars or whether it includes that 75kg, which is important, as that by itself cuts the weight difference in half.

 

 

They are wrong..

here are the real numbers :

Mclaren P1
DIN weight (kg / lbs)
1474 / 3249
Dry weight (kg / lbs)
1376 / 3033
Dry weight with lightweight options (kg / lbs)
1341 / 2956

LaFerrari:
Dry weight
1255kg


This means that its around 100kg lighter when Dry weights are compared.
The P1 adds about 100kg when it goes from DRY to DIN.
And i don't see why Ferrari should add more than 100kg in fluids.

It sure as hell wont go from 1255kg to 1474 in fluids...no way in hell!

Thats 219 kg

So my conclusion is that its a good 100kg lighter no matter how you cut it.

So like i said..Mclaren might want to reel in on the claims that nothing before the P1 and nothing after the P1 will be faster on a track

 

That is not a legit dry weight figure for the LaFerrari. Ferrari have not yet released the weight numbers so that is an estimate a few of the magazines have published.

Given how much heavier an Enzo weighed when it was put on the scales versus the figures Ferrari had released I would not put a lot of confidence in their numbers anyway. As someone else said, it seems like the data they release is dreamed up by the marketing department, not the compiled by engineers.

These are the dimensional specs released by Ferrari so far with the only mention of weight being its F/R distribution:

I still wager that in the real world the P1 will be the lighter car.

^ well that number must have come from Ferrari.

Now if you call it a lie..or that they usually lie..

That is nothing we can determine right now..

For now we have those numbers.

And IF its 1255kg vs 1376kg DRY ..there is no way in hell the Ferrari will weigh more when ready to drive.

 

 

Why MUST it have come from Ferrari?

The prevailing theory, and the one that I believe to be true at this time, is that the estimate of the LaFerrari's dry weight has been created by using the Dry Weight that Ferrari published for the Enzo back when it was introduced in 2002 - at the time the figure they provided was <drumroll> 1,255 kgs.

Link if you care: Ferrari Enzo

You may recall this slide released during the dealer presentation at Ferrari's Finali Mondiali event Valencia at the end of the 2012 Formula One season that referenced the F150:



Clearly there Ferrari is suggesting the new car will have a weight similar to the Enzo, or 0 kg increase. Then some resourceful journalist at Autocar who needs a weight figure for his LaFerrari article graphic has obviously looked back in the records and said, 'Well here is the number for the Enzo, lets just use that for now'. Almost brilliant, except for one thing which I'll get to in a second...

I'm not calling it a lie - I am saying it is a number that has been made up and that Ferrari have yet to release any official weight figure for the LaFerrari. That's the truth at the moment.

It isn't 1,255 kg dry - it isn't even close to 1,255 kg dry.

One very knowledgeable source in the Ferrari world made this statement yesterday:

"I can't get too specific but the curb weight is over 3,000lbs and under 3,300. No where near as low as 2,700lbs."

To keep the units similar, his range equates to 1,361 kgs to 1,497 kgs. Pulling out the figure dead in the middle of that range you get 1,429 kgs for a difference of 174 kgs or 384 lbs from this mythical dry weight of 1,255 kgs. No car has 384 lbs of ancillary weight - that's just unfathomable.

Lets get back to the Enzo though - the initial dry weight was listed as 1,255 kgs as noted above. By the time the car went into production the dry weight had magically been revised to 1,365 kg, or 3,010 lbs. That's a far more believable dry weight figure for the LaFerrari than 1,255 ever could be.

In the real world, an Enzo owner on Ferrari chat weighed his car on corner scales with a full tank of fuel and the Enzo was 3,265 lbs. Subtracting 29 gallons of fuel at 6.28 lbs per gallon gives a figure of 3,083 lbs which correlates very well with the production dry weight figure of 3,010. You still have several quarts of oil, coolant, and hydraulic fluids to make up the 73 lb difference.





And btw - 3,265 lbs is 1,480 kgs and when a LaFerrari owner finally goes to the trouble of weighing their car in the smae fashion, I fully expect its weight to be the same, or more.

I'm not sure how old you are but from your posts you seem young and very inclined to believe nearly everything you read. This is a mistake you will hopefully come to grips with sooner rather than later. In reality you should question everything as even official sources are known to get it wrong, stretch the truth, or just plain BS you. That's the unfortunate truth...

I am old enough to realize that you made a great post.

Which highlights the reality..

This time though ferrari has NOT said ( as you showed) that its 1255kg.

Meaning that they might get it right from the get go.

And it looks like it will end up weighing like the Enzo

Which is 1480kg in worst case ( according to you).. and the P1 is the same.

Which in turn probably makes all of them including the Huayra more or less the same weight as its 1350 dry.

PS
Rep for your post!
