Ferrari LaFerrari vs Mclaren P1 vs Porsche 918

Here's a fresh batch, the last one is kind of stale.

It looks like the 918 basically has a full 900+hp for the first part of the straight after recharging via braking into T6, but then at ~105mph, battery is dead. As you can see, it's still more effective to use full HL power in first part of straight to gain the speed jump. In RH mode, you would lose less at the top end, but more at the start of straight, so it may even be slower than running HL when battery is depleted.

 

Here is the corrected one.

P1 154 mph scaled down to 918's 144 mph, x axis scaled down to. Graph shifted & overlaid.

Another election rigged.

Nope, you've still done it wrong. You can't simply overlay one graph on the other and ignore the Y-axis values. You've just repeated the last mistake but moving the P1 graph. Now all the peaks are in the same place relative to 144mph as they were relative to 154mph.

You have to actually resize the graph vertically. This means reducing the vertical size of the 918 graph to 93.5% and then overlaying it. It's not going to be a 1:1 size fit afterwards because the scales were different to start with.

You see where 77mph is on the P1 graph? Well if a line is just below that, it needs to be above the 72mph mark when you transfer it to the 918 graph. JFC!

^When its put like that, the P1 looks slower than the 918. Does anyone know if treynor did a dyno with the LS test?

 

mkay, LMFAO, I thought about it a bit more and you were right. Here is what the final thing looks like.




this time I mean it: bye

Which is which?

 

Don't bother yourself, it's still wrong. He's dumped one plot on top of the other without adjusting for the different scales.

Hence why, in his graph the 918 is 10mph faster on the straight up to the corkscrew that it was last time they tested it. See at 1:02:00 in video linked below. Lap starts at 1:01:10. You can see all the peak straight and corner speeds match up with my calculations from Treynor's graphs to within 1mph. P1 is 5-6mph faster on the straights but 2-3mph slower in the corners apart from T6, where it's 1mph faster. It's obvious there's a lot more to come from the P1 when the driver gets used to it in the corners.

Mugabe,
If you haven't understand LMFAO, just make P1 looks faster and everything will be OK for him

 

I analized the two graphs very accurately and I have come to the conclusion than the LaFerrari is better and Top Gear don't deserve to test it

 

Does anyone know if there has been any confirmation of the LaFerrari's wet weight? Last I heard is that it's about 1600kg+.

 

Circa 150 Kg (600/4) ???
Explain to us please ....

Pop-corn also for me thanks.

 

best is he has no idea of the aero on the 918, as for P1.........well imv its a bit like the ring time....

 

I rescind that statement, he has it right now, see below.

 

600kg at 156mph.

78 = 156/2

Df = 0.5*Cd*A*Density*v^2

Half speed -> v^2 is quartered as is downforce. Y'understand?

Didn't you claim to be an automotive engineer on another forum?

 

It is actually embarrassing, what I did. My posts before, with graphs were wrong, as pointed out by LMFAO. This post discards all previous posts.

Now that I thought the steps through, I see where I was mistaken. It was one extra scaling. I was probably mistaken by my intuition that the centerline was the line of symmetry. Instead, that line was at the bottom. Oh, well.


Here is the correct, last graph from me. Sorry for misrepresenting the stuff.

Looks good now.

 

thread has mutated, blown up, reincarnated, warped beyond ridiculous... all because P1 lost another H2H. Staggering 'explanations'. it has become stupid beyond stupid beyond dumb.

 

Only to people who can't and/or don't want to understand telemetry. The P1 likely lost it on T2, T8 and T11, like I said. The three 40mph corners.

Wow.....I just discovered MugabeRobert is LMFAO!

On other forums, EMU (Germancarforum) and MYCROFT (Mclarenlife) posted the same graph saying he did it. So now we have EMU=MICROFT=LMFAO=MugabeRobert? And we see LMFAO going back and forth with himself (MugabeRobert) on the same forum?!

How many personalities do you have dude????!!!!!!

 

Oh. I'm amazed
You know Centripetal force and aerodynamic forces increase formulae. really astonishing.
So I have learnt today the P1 have 600 Kg@161 mph of downforce (142,6 kg @ 78 mph)
Let see
Putting together all datas it seems that the sizing to the vertical load is almost identical for both the 918 spyder that for p1. All tires have about 300 Kg of safety margin
What a pity that the P1, following the statements of the McLaren should manage 150 kg per tires e more load due to higher g he can pull (2,5 g).
Is there anyone who still believes in what McLaren state about its cars ?
LMFAO / Mycroft / Sloser still resists.

More Popcorn please.

Why do we discuss about a test of a P1 running not legal due to rear size not maching registration document and with after market TROFEO R tires ?

Don't argue with him, it's pointless.

He will change parameters in whichever way he likes just so he can appear to win an argument.

Lately he has been saying testings should only be valid if done on the same day and same tires and same etc.

But when cars are tested on the same day at Anglesey he doesn't acknowledge that's as a valid lost. He then claimed the next run by the P1 on a completely different day with different tires and who knows what else McLaren modified just so they can post a faster time mods that that time is a valid time to be compared to the other times recorded earlier.

Basically he is on both sides of the argument, depends on the results, same day do or do not matter.

 

Armchair racing... at its finest!

Means a lot to the website owners with all this click through. To most (but not all) of the rest of us: zzzzzzz!

Personally, I am most excited by the incoming 991 GT3RS. Should have outstanding performance at a fraction of the cost of these hyper-cars. Heck, about 8% of the cost of my P1 + 918! Probably close in track performance too but without the worry. In many ways, these hyper-cars don't make a lot of sense.

Sorry, OT.
