Comparison tests Porsche 918 vs McLaren P1 vs LaFerrari

[Monster]

For which market are these stripes on this STANDARD car?

Just to clarify, when you say strips, you mean those tapes covering the panel gaps between the top of the door panel and the roof panel?

 

[boyko23]

yes

It's clear, you have almost zero knowledge about the 918...
Nevertheless, the 918 doesn't need any excuses. It IS the Ring record holder, verified by reputable observers. It IS the record holder on all the tracks, it visited in 2014. Enough said...
If you are interested, read the SA remarks from HVS, I don't have time to loose...

Regarding the picture - sorry, I will have to drink the whole bottle.
Look at the next one. Am I the only one, who see a nice lightweight piece of carbon cover, instead of navigation system? Very Lightweight...

I think you'll find it's far from the fastest modified road-legal car. It isn't even the fastest production road car, that title belongs to the Radical SR8 LM.

I think you have already drank most of it anyway. Non-cost option. A 'lightweight bit of carbon' that weighs more than just leaving a tinted acrylic screen over the same spot.

Keep trying.

Yeah right!? They did it for a 0.000001% reduction in Cd, instead of just using race gas and upping boost.

Funny how no one mentioned that the fixed roof on the 918 covered 2 larger panel gaps where the removable roof attaches.

 

[Monster]

yes

And Emu thinks they are strain gauges or static pressure gauges...really? Not something as simple as using tape to cover up the panel gaps to further minimize turbulent air flow?

Turbulent surface air in the at the rear of an object is less likely to separate and cause drag because it causes more efficient velocity mixing across the boundary layer. Why do they put dimples in golf balls again? Look at the size of the gaps further down on the rear. This is getting a bit silly.

Emu,
don't distract yourself. Look at the navy system some posts above...

This is getting a bit silly? Really now? I don't have time to correct all your flawed assumptions from your previous posts but I will get to it after I deal with real life first.

So what do you think is the exact purpose of placing these "strain gauges" at these specific section of the car?

 

[ajjers]

Heh, well it's marvelous that Boyko mentions strip gauges as cheating on the P1 but you don't think a more aerodynamic, lightweight roof that lowers CoG and slightly reduces height is cheating.

The 918 probably will be faster on the road round bends if anyone is prepared to really push, except if it's wet. But mostly people will just do highway pulls on the street and the P1 will win.

What are you on about. Nobody is accusing McLaren of cheating because they haven't even posted a time. And yes all of the performance data collected on the P1 has been on prototypes, which aren't the same as customer cars either.

As for the roof, do you know how much a carbon roof panel in a 918 weighs? It's a few kilos. Putting a fixed roof in will have no effect on performance. Any weight savings (which I doubt there would have been) would have been more than offset by all the recording equipment Porsche installed in the car.

 

[ajjers]

Tech trouble? Don't tell me the Ferrari mechanics turned up again?

So ignorant. This was a customer Enzo tested by Black Falcon (independent racing team). It had problems with its hydraulic suspension which makes the time even more impressive.

 

[ajjers]

I doubt Sutcliffe has the skill to push the F1 car to the absolute limit.

He's a very skillful driver but he can't resist ludicrous hyperbole with regards to the P1.

 

[Emu]

Emu,

Already replied to that. Customer asks McLaren:

"Hey can I have my P1 with no navigation system?"

"Sure, it'll cost us less anyway."

"Can you also not install the gigantic box with the E-stop next to it?"

"We don't do that anyway."

So desperate to overcome the non-standard roof issue. Now you know why McLaren don't release 'ring lap times.

Measure either strain of static pressure for test purposes. I've already mentioned why this claim is ridiculous:

1) Given that the edited video clip doesn't show the timed lap, why wouldn't they simply remove the strips and do the video without them?

2) It would be a really dumb cheat. Given that it's a turbocharged car, the easier, less observable and more effective cheat is race gas and/or nudging up boost a few psi.

I hope you're aware that that test was one of the more valid independent test ever made.

-A bunch of a supercars from one owner.
-Fresh stock tires in every car.
-A successful racing pilot that knows the ring inside out...
-The pilot had an habituation time and gave a fair shot to every car.

In that test the enzo shocked many fanboys that believed that the ferrari was a mere showroom car that wouldn't stand a chance against its competitors.

And the enzo was running on a bridgestones that really weren't that grippy at all. Clearly inferior to the p zero corsa that some of its competitors were using...

Right.... keep telling yourself that.

The recording equipment is the same for all cars and disadvantages heavier cars less. Why is the light console not there either, or the upholstery on the roof? How thick is the roof? Next cars will be turning up with non-standard roofs and doors, then other non-standard body parts. Whole different ball game.

There's always an excuse with Ferraris. Makes the time more impressive or makes FIAT's reliability figures less impressive?

The following year it was beaten by a Viper. It was also beaten by a Zonda F CS on the same day, hence the excuses.

Think about this, the 956 record was set in 1983, the 918 has already gone 10s faster than the Formula 1 lap record set in 1976. Progress!

What time did a Zonda R run relative to a Zonda F CS? Think about it, the Zonda R is only 24s off 956 race lap pace and there's a faster version of that now. P1 road cars on Trofeos are probably putting down 6:4X. Add full racing slicks on a wider body and a race aero package and suspension and diff pus extra power and that will lop off serious time.

The qualifying F1 lap record (6.58) was set in 1975 and was on 22.8km version of the ring not the 20.6km that the 918 ran on. So no the 918 wasn't quicker, it was significantly slower in fact.

Similarly the qualifying lap record for the 956 is 6.11 which is over 36s faster than a Zonda R. Like I say, if the P1 gtr can get below 6.20 I'll get a Ron Dennis tattoo on my face.

The only person in denial here is you I'm afraid. It's not just a river in Africa.

Excuses? Ferrari weren't even there. The 'excuses' came from the people who did the test. 7.25 is an awesome time on those tyres, just made more impressive by the fact it could have gone even faster.
