Ferrari LaFerrari vs Mclaren P1 vs Porsche 918

Im actually saying this entire (pun intended) debate is meaningless since you can't really tell how different a tire is compared to the competition. Manufacturers have the option of creating a bespoke tire whenever they make their car, and if the competition doesn't do they same, then they can only rely on the car itself, and if that car isn't up to snuff, the oh well. So arguing against tires, is meaningless since the manufacturer didn't make a bespoke tire to bring out the best of the car, like its competition.

What would've happened if mclaren had decided to make a bespoke trofeo for the P1 since we've seen that infamous shot during the MT test, and porsche had decided to make an eco tire and then make a race version of the cup2, similar to how mercedes just did? This entire (pun intended again) debate would've never started, simply because you can't compare them as if they were normal tires. This would've just been simply on the cars, the engineering team, and which manu is the best.

 

Gt took tires out of equation when they ran all 3 on same tire (most likely corsa). The most amazing thing is that the 918 still won despite this type of track being more suited to higher hp opponents. Well done!

 

I for one would have been happy with whatever result since it proves nothing, except entertainment. Only one person seems to be getting aggro

 

Hmm no.

P1 has DRS mode AND a lowered Race mode, 918 has Hot Lap mode, different design philosophy. McLaren chases ultimate top speed on straights while Porsche goes the other direction, maximum speed out of corners. Getting fast lap times basically comes down to filling up area under the curve. Porsche traded top end acceleration for faster initial acceleration, it may ultimately hit a lower top speed, but it just fills up the area faster.

And Hot Lap mode doesn't just last one lap. That's some garbage spewed out by Mycroft. It is kicked in when one step past the detent in the throttle, same way the IPAS button works in a P1. Most people can't drain the battery on one lap simply because the car recharges so fast, from braking AND engine charging like the P1. Because of the small battery in the P1, the e-motor doesn't help much, only at wide open throttle and sometimes filling in torque output from the turbo lag between shifts. The engine also spend more time recharging the battery too because of the small capacity.

In Hot Lap mode, the driver controls the extra boost. In the 918 in Race mode the computer does the management as there is no detent in the throttle, but there is no extra boost, just regular output.

One little known fact, a 918 can recharge it's own battery from about 10%-90% in slightly more than 3 minutes.

 

It's amazing that you don't say anything about the P1 win at Silverstone, where it was running on Trofeos (and the LaF was on Corsas) and driven by a former P1 test driver. But when your car loses, even with a driver with no prior experience on those cars, all with the same tires, suddenly there are a number of factors (mostly conspiracy theories, but anyway), that contributed for it.

 

One fit his narrative, the other didn't.

 

1. I don't think you know what a straw man argument is.
2. I don't care about the HL mode in the 918 or that the P1 is faster on some tracks and the 918 on others because that's completely irrelevant to what you and I were talking about.
3. The only reason I brought up your 918 vs SV vs other cars saga was to show you how absurd your argument about the lap record at Fuji was, but it looks like that went straight over your head. You might as well tell me what you had for breakfast instead of bringing up the 675lt's lap record at Fuji, because those two things have exactly the same impact on the conversation about the Egg's lap record, i.e none whatsoever.

Also, I'm not bragging about anything, I'm trying to show why the Egg didn't go faster than it did at Spa (or Suzuka for that matter). I'm actually doing the exact same thing with the Egg that you're doing with the P1, but I'm using facts, real world observations and an objective viewpoint to present my arguments instead of conspiracy theories and grasping at straws that doesn't even exist.

I'm just amazed that someone who breaks down every single test, word and hearsay into tiny molecules in regards to lap times just completely ignores every single thing being brought up that doesn't favour your position.
I've called you a hypocrite two times already but every single post you make only confirms it more and more so it's difficult not to continue doing it.

 

How do you know? Are you an Apple Mac user?

 

Well fine, but many in this thread assume the result proves something. If you watched their drag races, that probably proves something, namely unpredictability. Now apply that to lap times.

 

Garbage that was proven beyond doubt by the Laguna data. 1s slower on lap 2.

 

They weren't all with the same tyres. The 918 had Cup 2s on and bespoke ones at that.

 

1. When a person makes out that you said something you didn't.

2. Perhaps if you've forgotten what we were talking about.

3. The One:1 at Spa had a factory test driver, so no excuses I'm afraid.

Incidentally Porsche also had Patrick Long (factory test driver) at COTA but they never released a lap time, or a full lap video. Obviously it failed to beat 2:17.

 

That's incorrect. They said that they ran the cars on similar tyres. Their definition of similar is the stock tyres that each came with.

 

Hearsay, non factual info from your fantasy land.

 

My favorite thing is when you educate well informed owners about their cars. It's amazing. I don't even know how many track miles Whoopsy has on his 918 but of course you know way more than he does.

 

I appreciate the technical detail. A lot. This information is hard to come by.

 

Unfortunately it isn't garbage though. Both treynor's graphs and MT's data release showed that the 918 was 1s slower on the second lap of Laguna, and that was down to reduced acceleration on the straights. That was all shown very clearly beyond reasonable doubt.



Furthermore the P1's battery isn't really much smaller than the 918's - 4.7kWh vs 6.8kWh. And the P1 is only running 1 e-motor off that and is only producing about half as much e-power as the 918 produces in HL mode. As well as filling in for lag, it also adds 179hp on the P1. And the P1 has plenty of opportunity to recharge that during traction control instances, which are more frequent for RWD and during non-WOT conditions. But because the kW discharge rate per kWh of charge is lower for the P1, the battery also drains far slower.

We see here how a P1 can complete 2 full hot laps of COTA with zero reduction in performance, driven by a pro.

Sadly the actual evidence does not support your claims. Good day.

Or 2 slow laps. So 1 quick lap at Laguna and 2 slow. Wow, I bet that's real useful on track days.

Hahahahaha. Go to 1:01.11 in the video. 'MICHELIN' is written in big letters on the side of the tyres.

I can't believe the 918-die-hards still refuse to accept this.

 

Evidence doesn't lie. MT provided data showing that the 2nd lap was nearly a whole second slower. And according to treynor who was actually there, it was 1.5s slower on lap 3. He also showed velocity traces of all 3 laps as shown above.

So it doesn't matter if Whoopsy has driven to Mars and back in a 918, the evidence is irrefutable.

 

Are those graphs available with labeled y-axis?

 

Both 918 and P1 did their quickest laps that day on the very first lap they ran. So that certainly doesn't prove that the P1 is any better at holding onto its battery power than the 918. You're only conclusion could be that they're both good in that regard or they both suck. Not that one is good and the other isn't. One fact you can't refute is that 918 was quicker by over a second. And with that, I'll end my arguing with you for the day and go enjoy the first light snow of the year with my pup.

 

What is your source for this? At about 1:07 of the video, Richard Hammond says "the exact same tires". That does not mean "similar".

 

Ok, so let's talk about the second lap then. How much slower was the P1's second lap in comparison to the 918's second lap? You magically "forgot" to reveal this info to the public huh?

Let me be absolutely clear. Based on the real data from the MT test, in a two lap race, the P1 falls further behind by a whopping 1.6-1.7s!!!

I think for your sake Lieven/Mycroft/LMFAO, let's just stick with 1 lap huh? You are just digging yourself a hole that you can't get out of.

 

The y-axis is speed but you'll need to ask Treynor. MT data posted by boyko earlier also showed the 918 1s slower on lap 2. You can see from the MT supplied graph what the peak y-axis values are though.

Incorrectomundo.

The P1 was fastest on the 2nd hot lap it did, when they were running them with breaks in between.

And Jason Hart ran two laps back-to-back at COTA with only 0.02s in the difference.

treynor's graph from earlier practices at Laguna also show no difference in peak speeds on straights in consecutive laps.

As regards speed, the P1's best sector times added up to a perfect lap of 1:29.70.
