Ferrari LaFerrari vs Mclaren P1 vs Porsche 918

Fast, really fast!

Right okay but someone else on this forum recently said there wasn't as an excuse for the Laguna car running out of steam. So difficult to keep track of all the bull****. Fairly sad that your stories change so many times. Don't suppose they'll own up now anyway.

 

That's OK, there is even re-gen in e mode from the brakes, To be fair it all depends on just how much you have in the batts to start with, I had about 80% and after 6 laps of Silverstone it was down to about 40%, using HL mode......I then switched to sport mode for less than a lap and it was back up to well over 60%,

Next time I go round I will take a pass, and vId the batt re-gen so you can see....

 

The problem is that charge level isn't necessarily indicative of horsepower and continuous delivery thereof because of voltage and engine management. It's very likely that the ECU will manage delivery to ensure HL is always at lest as fast as RH or faster, therefore charge use and continuous HL use will be reigned in.

When you think about it, HL mode is likely pushing 230-260kW (308-349hp) from a 6.8kWh battery running 385V nominal (606A), wheras a P1 is pushing only 176hp from a 4.7kWh battery running at 535V (~245A). So the 918 battery is actually undersized relative to its power consumption.

4.7kWhx3600s/131kW = 129s (P1)

6.8kWhx3600s/230kW = 106s (918 HL)

6.8kWhx3600s/208kW = 117s (918 RH)

However this only looks at power consumption, not charge consumption, which is actually dependent on current and the 918 is drawing more than twice as much current - probably a result of needing more torque since the front e-motor has no gearing, whereas the P1 e-motor has a 2:1 reduction ratio (130Nm -> 260Nm) before it even goes through the gearbox.

Exclusive: McLaren P1 Review

4.1Ahx3600s / 245A = 60s (P1)

5.9Ahx3600s / 606A = 35s (918 HL)

So the 918 is using battery charge almost twice as fast relative to the size of its battery. That brake re-gen is not a bonus, it's a necessity.

This is all incredible.

Just absolutely Fookin Incredible!

It simply takes your breath away, really.

I'm/we're almost at a loss for words here.

It/He never stops (regardless of the legitimacy of the previous statement he's responding to, and the idiocy, lack of knowledge, or filibustering-semantics of his current one).

Oh My (mouth agasp, aghast, agape, etc.)!! True McLaren Energizer Bunny indeed.

Nonetheless, more Popcorn please (at least for the entertainment factor)!!

Truly incredible indeed!

 

We've seen it all before. How was it? "Mclaren: there is no finish line"

 

Yes, there's no finish line with him truly.

However, to do what he's doing, the way he's doing it. He must be getting paid, or at least be a pimply faced, hormonally imbalanced, impish 13 year old with McLaren posters painting his bedroom walls.

This is not even trolling anymore. It's just plain scary, and/or embarrassing.

Nonetheless, more popcorn/don't stop. I can use the laughs (whenever I can suspend my common sense, glazed over-teary eyes, and logic while reading his post, of course). LOL

SMH

 

Same thing I use to think about all other non owners/McTrolls who have been alternating on this thread. It must be working out well for some, in which case kudos. But I suspect it's all just smoke and mirrors as McLaren is not really the healthiest of companies ATM and for the love of god I cannot see any appeal in their products, but that might be personal. I have them all on ignore btw. It helps.

 

Yeah, there's something going on indeed.

You notice, every time there's a McLaren loss somewhere, the internet team comes out in full force, seemingly to drown it out, change the subject?

Funny: I was thinking this before you wrote your response. But you notice, McLaren loses another H2H with the 918 with Motor Trend, then bails out with Top Gear (again), but all we hear is what the 918 supposedly can't do ad nauseum/Rinse and Repeat from McLaren Trolls? That is truly rich, isn't it?

Gotta be synchronized PR/Propaganda thing indeed?

Ironically, who really cares about all the track times if it's a truly good car, and/or if Ron Dennis (and subsequent web trolls) didn't open up their big, loud, incessant mouths stating it would slay all comers anywhere, anytime to begin with? It's a Hyper Car and should be enjoyed, admired as such. However, they put their foot (and the spotlight) in their big, collective mouths, and continue to do so.

Weird!

 

It reminds of the Apple fanatics, of which I am one, but with the substantial difference that Apple products are often proven better than the competition

 

Hey! Who says Apple always beats the competition!?

Haha. LOL.

Well, at least Apple has a great track record, and years to fall back upon in the consumer arena.

McLaren had one major success years ago (the F1), then came out with a great car years later in the MP4-12C. And now the P1 and 650 follow, and so forth. Good for them. But certainly not Apple territory.

Oh. Apples in Superlative financial health BTW. McLaren; maybe not so much. LOL

So one company (or it's fans) has a reason to scream in general. And the other, should be holding their collective breath really (at least in the financial realm), while rightfully admiring it's successes up to date.

 

As I said, Jason here is the mole in Whack-A-Mole game. It keep popping back up.

You guys have to admire his resolve. He spent all night on the internet to find some big numbers and then do a bunch of calculations before posting them. Doesn't matter it make sense or not, in his mind it does.

While he is doing all that, I took my 918 out to set another timed record, beat the P1's time by 30 seconds but I didn't invite the P1 so it loses, AND I purposefully drove on morning dew just so I can claim my tires didn't provide optimal grip.

In another news, my buddy's P1 won the most important contest though, he stuffed 3 bottles of water in the P1 while he can only mange a single bottle in the 918. Humiliating defeat for the 918 I would say. But in the spirit of Jason here, I told him me in the 918 will win over a 10 lap race, cause if he drink all 3 bottles he will have to stop and take a piss but I can hold it till the end drinking only 1 bottle.

 

^^Iirc the f1 wasn't such a succes either at the time it was released and I still don't like it. Since then they basically just did one more car, although in different guises, which isn't a resounding success either. I would really like to understand where all the appeal is, although I have a new theory. Maybe these people are trying to impress some of the most famous customers besides the factory itself.

 

Sure it wasn't a success commercially at time of production, but you can't knock Gordon Murray and the team for ambition or final result. However £627k on the street mid deep recession isn't easy for anyone. Hey Apple mid 90's weren't too rosy either, if I recall they were knocking on heavens door at the time. ( yes I do have multiple Apple products and v happy with them )

 

However having an unplanned Le Mans outright win is priceless to many...

 

All makes sense above.

And I was thinking the same regarding Apple in the mid 1990's and Jobs eventual ouster.

However, you can't deny the number of successes, breakthroughs and consistency Apple had (and I'm not a fanboy in the least) since he went back to the company, compared to McLaren entire consumer existence/track record for example (mind you, the two companies financial health extremes).

And yes, that Lemans win was/is priceless too many indeed. LOL

 

If I had to liken Apple to a car manufacturer, though, it would have to be Porsche. There's a long documented story of the two companies being associated in a way or another and the 918 is definitely the most "i" product among these three.

 

So in English, the reason the HL mode is only good for one lap is due to battery.

So that means when battery tech improves HL mode would last longer, or could possibly never run out.

That also means more power for the mac. Should both companies release upgraded batteries of course.

Interesting times we live in. This thread will probably last another 10 years.

 

There already is a battery producing more power (200ps) in the P1 GTR.

It's interesting that the rate of charge use actually depends on the torque you require from your e-motor rather than the power. By using gearing and a higher voltage (higher motor speed), you can reduce the torque and rate of charge use (current (A) = Coulombs (Q)/time (s)). This must be how McLaren was able to do away with brake re-gen.

In 5 - 10 years god knows how light and efficient bats will get.
I wont be surprised if they were half the size and double the output. For those that will say "yeah but that's gonna mess up the balance and weight distribution"...

Fine

Same weight and quadruple the power

 

Battery tech is the one area we still havent had that "AH-HA!" moment with. There is a chance they are getting close to it with some of the new ideas surrounding elements to be used in batts.

 

If your leaving all other components and settings the same it would be same weight four times the duration (capacity).

 

I can just see LMFAO replying with some sort of statistic for exactly how much water you would need to drink along with proof that the P1's water carrying ability has been proven to be better than any other cars................. Beside's which surely you could just pee in one of the empty bottles.

Either way that is a hilarious post.

 

What a respectful member of another board have to tell us about 918's high speed performace... :

"We discussed before about the 918 having a relatively slow (for 887PS) 200-300kph time of ~12.7s.

I can report that the 918's horse power seems in quite good health at very high speed.

We raced the runway on Saturday at Dunsfold (where Top Gear is filmed) and in around 1200m the 918 managed 309kph.

My GT2 reached 303kph with ~840PS, OK I had the time consuming gear changes hampering acceleration but the 918 was very impressive"
