Comparison tests Porsche 918 vs McLaren P1 vs LaFerrari


Hopefully we will get Treynor's take on this because his story refutes this. Given that they used 2 sets of tyres, it's clear this isn't the full data in its entirety though.

Let me put it to you this way...

If the position was reversed and it was a 918 owner who kept on releasing his data before the article is published, starts making "certain claims and theories" about the P1. Then the Motor Trend's official data shows the result in a completely different light, wouldn't you become a little bit suspicious regarding the "fairness" of the 918 owner's data and claims?
 
The car had squirelling also when accelerating and this could be due to few factor. Waiting for MT Video. You tend to count your chickens before they're hatched.
The Top Gear test showed the P1 only 0.1s slower stopping from 100-0mph with PZCS tyres, that's about 3m. The MT traces show a braking delta of 2-4m/s. Over a 4s brake from 100mph, that >10m on stickier tyres.

You have serious problem to discuss about cars, now do you want to switch to
football ?
Do you always like to loose EMU ?
I hope laferrari EVO Anglesey video will be released soon and you will go hiding in Greenland because a customer LaF with use PZCS lapped faster than P1 press car. Lol
Still won't beat the Trofeo R time. You may remember the 458 also won on Bedford but we know who came out on top overall.

Having said the Pzero corsa is a streetable Track & Competition tires so superior on track to the MPSS you are mixing apples with bananas using old 458 lap times and in different days
Yeah you'd like to claim that wouldn't you. More like PZero is hugely inferior to MPSS. PZero was only really equivalent to the older PS2.

What else Emu ?

Or the variable track conditions are good only when they suit to you ?
Dry tracks. Strange how you start by quoting a LaFerrari lap from a different day and then use different days as an excuse. The non-one-on-ones don't use the Ferrari tweaked car.

The 918 tyres are the same of the 991 gt3. Deal with it.
Rubbish. GT3 tyre test was size for size not undersized like P1 Trofeos. MPSC2s on GT3 had wrong pressure hence why 4s slower than 458S.

keep tryng to lower the CoG of the P1 but take in count that CoG height of a F1 car is around 0,25 m to the ground.
Taking Treynor P1 kerb weight and a 70 kg driver alone you need 0,185 m CoG height to pull 2g and 600 kg of downforce. At max load you meed 0.145 m height.
McLaren BS is under the sun, RD is accustomed to lying.
See Alonso recent crash.
P1.webp
No you don't. I've already shown the calculation over on Fchat. Max g is calculated under optimal conditions.

Trofeo R - 235 1476lb, 305 1874lb

F+R Tyre Max Load = 3350lb = 1521kg

Vehicle Mass with driver and 5% gas = 1380 + 5 + 75 = 1460kg

Track = 1.658m

F+R Mass + Downforce (kg)/2 = (1460/2) + 600/2 = 730kg + 300 = 1030kg

1521 - 1030 = 491kg

Max Lateral Mass Transfer = 491kg = Mass * (Hcog*2)/Track

Hcog = (491/1460)*(1.658/2) = 0.278m


Not a problem since 918 has a CoG of 0.33Xm and everything on the P1 bar the battery sits lower. Actual CoG is infact about 3-4 inches lower than the 918. It has already demonstrated over 2g in tests anyway.

Not if the owner's data clearly showed 3 lap traces with the footprint of a 918 hit lap and the 'official' data only had two.
 
From McLaren life (Mycroft)

<< I'm not seeing how the lack of a mechanical LSD is a disadvantage under braking. That actually leaves you more free to control the rotation speed of each wheel in the optimal manner surely. It's certainly not a disadvantage under acceleration >>

LSD or better a locking differential distribuites torque both when it's accelerating torque than braking torque. That's means under heavy braking the excess of braking torque could be distribuited to the other wheel instead to have ABS intervention = less braking distance
Locking percentage could be different between accelaration and braking phase.
The E-diff Ferrari permits a 100%-0 / 0 - 100% distribuition both accelarting than braking
This doesn't actually help with braking though. Nobody has complained about the P1, 650S or 12C's traction. Randy in fact applauded the 650S's traction. When you're continually monitoring wheel speeds, braking torque can be adjusted on the spot for each wheel. Ultimately you match braking torque to grip continuously thousands of times per second.

The braking in the TG test only showed 0.1s difference 100-0mph with PZCS tyres vs Cup 2s, which is to be expected. With Trofeo Rs I would expect the gap to close, not grow hugely.

Essentially the P1 distributes left-right torque the same was as the 918 distributes front-rear torque.
 
You just don't get it do you DUDE? I extracted the Veyron vs M600 data as well to add in another important comparison for perspective purpose that the Veyron makes mince meat of the P1 and 918 above 150mph.

You personally have got some incredible childish obsession with the P1 that you so honorably defend all its weaknesses. It is a fantastic car for sure, I really do like the P1 alot, but so many people including myself have pointed out that the 918 has proved to be a much better opponent to the P1 than all of us and McLaren could have ever imagined. In track comparisons it has proved the equal of the P1 and as well as even better than the P1 in a few comparisons. In honesty the P1 has been a disappointment as its over hyped performance claims have never been matched and its boasting about its incredible downforce aiding its track ability has not been well proven when a car that doesn't have such downforce (918) as been just as quick and even quicker on any track the magazines will want to compare. In performance terms the 918 and P1 are an equal match. I honestly think Ferrari won't want to bring a LaFerrari for proper track and performance comparisons with both 918 and P1 cause they fear their car won't win and actually be beaten by both these wonderful hypercars.
Er no. You made a point about the 918 vs M600 and then posted Veyron SS data. That didn't make sense.

The Veyron SS acceleration from 100-200mph is actually very close to what the P1 made in the 918 vs P1 h2h. 17.2s vs 17.51s. Yet you claim the 918 can be close to the P1 after 165mph with only 756hp and 458hp/ton???? Nobody is being childish here. HP and PWR have very obvious affects on acceleration.

Yes you are right HP and PWR do have an affects on acceleration and so do torque output, gear ratios and at high speeds, aerodynamics. The P1 has more power for sure, but the 918 has much more torque. Well I am not claiming anything, it has been proven and tested that the 918 is close to the P1 after 165mph. One source that you keep referring to, Autocar has shown that exactly from 0 all the way up to 180mph. The 918 is actually faster from 0 up to 90mph, but from there on it trails the P1 all the way up to 180mph by only 0.2sec, which is really an eyeblink. This same test car was used in the head to head comparo as well as in the AMS/AS and AZ tests. 0.2sec is negligible really cause this can be also attributed even to a worse reaction time off the start. Topgear got identical 0-100mph acceleration for both cars.

Torque actually doesn't play a part at higher speeds, more at lower speeds. The P1 top end is broad enough to be around 900hp for >1000rpm. This is the same reason the 650S is faster than other cars in its class, broad top end.

Unfortunately you're using data from the same magazine that tested the two head-to-head and found the P1 to be decisively faster. As I've said the earlier P1 figures were badly affected by wind, which massively affected high speed acceleration, note also the damp - "mostly dry". On the same day test, this was the same for both parties. The quoted 1s reduction in 0-300kph time for the 918 WP is a joke. How does a sub-2% all-up weight reduction and increased drag give a 5% reduction in time?

As mentioned previously there is a reason the M600, CC8S and F1 all have 0-200mph figures, whereas the P1 doesn't, despite being faster. F1 - 19.2s 0-180mph. P1 - 18.0s, 1.2s different but in the 918vsP1 head-to-head the P1 record a 0-200mph time 5s faster than the F1 despite being tested on an inferior surface. Stop ignoring the obvious. And by the way, according to Ferrari the LaF would be as fast as the Ducati up to 150mph in that test.:ROFLMAO:

The 918 benefits off the line but the P1 is a full second faster from 60-150mph, being faster over every interval after 60mph.

Emu do you really believe Autocar's figures are 100% correct? Look at the P1 time and speed to the km mark (18.2sec at 178.5mph) and then compare this to its supposed acceleration to 180mph in 18.0sec, some obvious editing discrepancies. The 918 as per their road test is 0.1sec faster than the P1 from 150mph to 180mph! So where does this loss in power affect the 918 high speed acceleration above 165mph? And it has the same time to the km post (18.2sec but higher speed of 180.4mph), obviously there is something wrong here.

You mention wind ruined the high speed acceleration in the P1 test, where does that say that in the road test? No mention in the road test at all. Read the performance paragraph.

If you compare the rate of acceleration with this P1 road test car and the car used at the head to head with the 918 they are pretty consistent up to 150mph. 30-150mph in 9.2sec road test vs 9.43sec for the head to head shoot out on less than ideal surface. Interesting stat now in the road test the car does 21.4sec to 190mph which is a 3.4sec gap from 180mph to 190mph and achieved on a better surface than the H2H. How can it possibly gain on acceleration rate to close the gap to 1.89sec difference from 190mph to 200mph (23.29sec less 21.4sec)? That is impossible as the drag will increase as speeds increase. Not even the Veyron is that quick it requires 2.8sec between 190mph to 200mph and has 300hp more than the P1! Using the P1 test car as a reference again, the acceleration rate will decrease to at least a 3.6 to 3.8sec difference between 190mph to 200mph, so that test car would have achieved a time of about 25 to 25.2sec to 200mph. To 150mph the time at H2H was about 0.6sec slower than the road test car. It would be close to impossible for that car to match the test car acceleration to 200mph, it would be at least 0.6 to 0.8sec behind so looking at 26sec.

You cant honestly believe the Porsche 918 time of 29.7sec to 200mph is correct. It got to the mile at 25.82sec at 194.64mph (313.24km/h). Its acceleration rate between 30-150mph is about 0.4sec slower than the 918 road test (which is the identical car used), so to 180mph this H2H car would be about 0.6sec behind at 18.8sec compared to the road test car. How can its acceleration rate drop so much that it would take 7sec to go from 180 mph to 194.64mph (25.82 less 18.8) and 10.9sec from 180mph to 200mph (29.7 less 18.8)? That is impossible unless they backed off the throttle after 180mph.

After explaining all of the above do you understand now why i say those H2H 0-200mph times were total hogwash for both cars?

There are several explanations for this.

Firstly, this is also a common source of confusion in quarter mile drag racing. The time is done to the finish line, the speed is averaged across the last 66ft, not sure how it works in standing km.

Secondly, it is a direct result of speed averaging. The kilometer time is a 2 direction average and the speed and acceleration results are also an average. Hence there is no reason for them to align. The km time isn't as badly affected affected as the high speed acceleration, because you're still going fairly fast.

E.g. The km time may be and average of:

18.6s@165mph in one direction &
17.8s@192mph in the other
18.2s@178.5mph Average

The acceleration may be an average of:
0-180mph - 22.0s* in one direction &
0-180mph - 14.0s in the other
0-180mph - 18.0s Average

*clearly going to run out of room before 200mph on this run, hence no figure recorded for 0-200mph.


You mention wind ruined the high speed acceleration in the P1 test, where does that say that in the road test? No mention in the road test at all. Read the performance paragraph.
I think you've just inadvertently proved it yourself. The fact that km speed and acceleration times are misaligned is the proof.

If you compare the rate of acceleration with this P1 road test car and the car used at the head to head with the 918 they are pretty consistent up to 150mph. 30-150mph in 9.2sec road test vs 9.43sec for the head to head shoot out on less than ideal surface.

It would be close to impossible for that car to match the test car acceleration to 200mph, it would be at least 0.6 to 0.8sec behind so looking at 26sec.
Wind affects lower speed acceleration less because there's plenty of surplus power, e.g. 0-150mph. Traction is the dominant factor up to nearly 90mph in a P1. Again it is the inconsistencies between these results that demonstrate the different wind levels in the individual tests. This is why you can't take a time from the individual test and expect it to align with the head-to-head. Different wind speeds. You still can't explain why the F1, CC8S and M600 all recorded 0-200mph times in the individual tests on the same test track but the P1 didn't. Wind, wind and wind. See in bold above.

You cant honestly believe the Porsche 918 time of 29.7sec to 200mph is correct. It got to the mile at 25.82sec at 194.64mph (313.24km/h).

That is impossible unless they backed off the throttle after 180mph.

After explaining all of the above do you understand now why i say those H2H 0-200mph times were total hogwash for both cars?
No, it's still you that doesn't understand the affects of win on 2-way averages I'm afraid. How fast do you expect a car with only 756hp and 458hp/ton with a few hundred kg of downforce and side aero parts to get from 180-200mph anyway? I'd say probably about 10s. The F1 took 8s and it has 627hp and 560hp/ton and is very slippery - good for 240mph aerodynamically.

What likely happened is that the 918 ran its individual test on a very calm day and recorded 18.2s 0-180mph in both directions. On the head-to-head there was some wind but not as much as when the P1 did its individual run. Traction cost both cars about 0.5s up to 150mph with wind not really playing a part at these speeds.

918
26.4s@189.6mph in one direction &
25.2s@199.6mph in the other
25.8s@194.6mph Average


0-200mph - 33.7s in one direction &
0-200mph - 25.7s* in the other
0-200mph - 29.7s Average


*Probably how zee German's recorded their result.

P1
26.1s@200.8mph in one direction &
24.9s@208.8mph in the other
25.5s@204.8mph Average


0-200mph - 25.8s* in one direction &
0-200mph - 20.8s in the other
0-200mph - 23.3s Average

 
Just for you EMU.....

As my Porsche source was telling me regarding the Motor Trend comparison, they had a pretty easy afternoon after the 918 set the initial bench mark time. They kept waiting and waiting in the pit lane, wondering if they were going to go out again should the P1 bested the 918's time. They were also expecting 918's time can be improved with a few more additional tweak to the tire pressure.

But they were never under the pressure to go out again....

The data from MT just proves that both the P1 and 918 went through the proper battery charging lap and none of the 3 laps nonsense. The 918 never ran on the LS track in Race mode since the head to head comparison was about who is the absolutely fastest around a track, NOT who is the fastest in a 10 lap race. Even if 918 ran under Race mode, the delta difference at LS would be well under a second as indicated by my Porsche contact and this would be consistent performance lap after lap.

Another interesting thing that I learned from my Porsche contact is that if this was a 10 lap race, the fastest way, and have the most consistent lap times, is to alternate between Hot Lap and Race mode during the lap (Hot Lap between turn 11 to turn 1, turn 5 to turn 7, Race Mode in the rest). If one did that, the delta difference should be around 0.5s (from 918's fastest lap), but it would maintain the battery lap after lap and produce fast consistent lap times.

There goes the theory of the P1 being faster in a 10 lap race huh.....

I believe Treynor has already corrected your drivel and provided telemetry and we know what happened to the Lieb 918 on Dottinger. Enough said.

Heh. Both CL and Boyo have been on my ignore list for a while because of low S/N and trolling. The latest comments quoted simply illustrate once again why their posts are worth filtering.
 
just give up, everything you say have been contradicted by official data, the knowledge of users on this forum (and Fchat) and actual owners of the cars
Sadly my information comes from someone who was actually at the test, who owns a P1 and has all the test telemetry. It is interesting that owners say HL lasts longer and also interesting that this year's 918 was an average of 3-4mph faster on every straight. It'll be interesting to compare charge depletion rate between the 2014 918 and the 2015 918 if MT launch a video of the day.;)

As for Fchat, LOL, just LOL. Note how the Ducati 1199SL does 100-150mph in 4.5s in the Autocar test. According to Ferrari, the LaFerrari does 100-157mph in <5s - 9.6s@157mph quarter mile. So the LaFerrari is faster than a Ducati 1199SL.:ROFLMAO: Fchat are the sort of dummies who defend crap like that.... and the 1360kg kerb weight. They count 2 mechanics as 5 and 2 sets of tyres as 12, except for Porsche, where 2 mechanics were counted as zero by the Fchat le crunch bunch. Let's face it, you have to be really 'special' to believe Ferrari are honest.
 
That's what I've been saying. Tests and owner reports have shown that current gen ferraris perform the same as specs indicate. But after that chris Harris piece, everyone thinks ferrari still cheats.

while i can agree that they have improved after they were caught cheating, you also have to remember that this is their halo car and that they would want this to preform better than it's competitors more than anything

I do agree. But, if I pull an emu here and go in with science, judging by the weight that a few have posted around here and there and we say that the Laf is 1500 wet, and it supposedly has better front-end grip, and it has more power, it should be able to at least win against the P1.

Secondly, it is a direct result of speed averaging. The kilometer time is a 2 direction average and the speed and acceleration results are also an average. Hence there is no reason for them to align. The km time isn't as badly affected affected as the high speed acceleration, because you're still going fairly fast.

E.g. The km time may be and average of:

18.6s@165mph in one direction &
17.8s@192mph in the other
18.2s@178.5mph Average

The acceleration may be an average of:
0-180mph - 22.0s* in one direction &
0-180mph - 14.0s in the other
0-180mph - 18.0s Average

*clearly going to run out of room before 200mph on this run, hence no figure recorded for 0-200mph.



I think you've just inadvertently proved it yourself. The fact that km speed and acceleration times are misaligned is the proof.


Wind affects lower speed acceleration less because there's plenty of surplus power, e.g. 0-150mph. Traction is the dominant factor up to nearly 90mph in a P1. Again it is the inconsistencies between these results that demonstrate the different wind levels in the individual tests. This is why you can't take a time from the individual test and expect it to align with the head-to-head. Different wind speeds. You still can't explain why the F1, CC8S and M600 all recorded 0-200mph times in the individual tests on the same test track but the P1 didn't. Wind, wind and wind. See in bold above.


No, it's still you that doesn't understand the affects of win on 2-way averages I'm afraid. How fast do you expect a car with only 756hp and 458hp/ton with a few hundred kg of downforce and side aero parts to get from 180-200mph anyway? I'd say probably about 10s. The F1 took 8s and it has 627hp and 560hp/ton and is very slippery - good for 240mph aerodynamically.

What likely happened is that the 918 ran its individual test on a very calm day and recorded 18.2s 0-180mph in both directions. On the head-to-head there was some wind but not as much as when the P1 did its individual run. Traction cost both cars about 0.5s up to 150mph with wind not really playing a part at these speeds.

918
26.4s@189.6mph in one direction &
25.2s@199.6mph in the other
25.8s@194.6mph Average


0-200mph - 33.7s in one direction &
0-200mph - 25.7s* in the other
0-200mph - 29.7s Average


*Probably how zee German's recorded their result.

P1
26.1s@200.8mph in one direction &
24.9s@208.8mph in the other
25.5s@204.8mph Average


0-200mph - 25.8s* in one direction &
0-200mph - 20.8s in the other
0-200mph - 23.3s Average
What a load of absolute Bull Sh&t you write. There is no proof of any wind playing a negative part in the test results of the Autocar P1 test. In England the wind doesn't blow that hard to make a huge impact on acceleration and speed runs and if the wind was gusting like mad above 40km/h for example it would be stupid and unsafe to drive those cars at high speeds cause the wind wouldn't come in only one direction against the front but could blow against the side of the car as well!. And are you an expert to know exactly if the wind will blow against the runway in the opposite direction to what the car is travelling? Do you actually go and stand there and watch the wind sock all day to see which direction the wind is blowing and stand there with your wind meter and tell the test drivers, ok chaps the wind is gusting in opposite direction to track at 30km/h now we can get a great average time?

How can the speed and distance and time not align? That is what acceleration rate is and its mostly constant with the P1 and 918 as i explained to you, road tests figures compared to H2H. There won't be huge variance in 2 way averages for sure as then there will be something wrong with the car for sure in its power delivery. And you cant prove there was wind blowing on the track that day.

The standing km time as mentioned is started from standstill and is a full bore acceleration run to the 1km mark at which point the car will obtain a time at a certain speed. Some magazines do perform a 2 way average for this as well and include it in the road test performance data.

Its no use writing anything for you to understand, you are so ignorant and biased towards the P1 that you not willing to open your eyes to any faults in the road tests of both cars. You are the only one for sure that believes everything Autocar writes, which scientifically and proven by other magazine test results is not 100% correct.

I'm surprised that you haven't mentioned all the other tests that have managed to get the 918 to 180 in under 20secs
