Ferrari LaFerrari vs Mclaren P1 vs Porsche 918

Then you must purchase Veyron Super sport with +410Km/h top speed it is because of your real world is filled with straight lines you will lost your way with P1

 

Oh OK. So that explains if, if true?

 

As always you are right, In my opinion here at this forum you and Napolis = 2 gentlemen with always very fair and accurate posts and opinions, Many Thanks, and I appreciate you very much!
As you said many times here and in another forums 918 was designed to be the fastest on tracks and real world, and till now it is 100% confirmed to all, the 918 is the king and always it is ready to beat P1 , I was a participant of a private h2h at yas Marina and it was again 918 to win and P1 as always a looser

 

Strong words, though I myself began to have doubts that SS was impartial when it came to comparing these two vehicles and checked his facts. Back in March he wrote in his blog (note the term 'generates'):

"They, McLaren, reckon the P1 generates as much as 5G of cornering force around corners like Blanchimont (at Spa) and Copse (at Silverstone), and having driven it around Bahrain, I believe them. The 918, on the other hand, doesn't even get close to that sort of grip."

McLaren P1 versus Porsche 918 Spyder - which is best? | Autocar

When readers began to question this statement, he did eventually post a correction in the comments section when having checked this claim with McLaren and it transpired that this 5G figure was referring to their F1 car. McLaren's statement read (note the term 'withstand'):

"the P1 can withstand lateral forces of up to 2g when cornering and braking."

This section has to this day not been corrected on their website. It makes one wonder whether a few seconds here or there and their accuracy are really checked thoroughly or are just cited to be able to use the term "blitzed"...

 

Ss's best mate from autocar now works at mclaren. Nuff said!

 

Yeah. You hate to say it, and would love to give them the benefit of the doubt. However/Unfortunately, the recent history doesn't show this with SS concerning this subject matter. No biggie. It is what it is (or appears to be).

 

Interesting. It's that finally a P1 graph?

Seems consistent with the batteries discharging in a little over a minute at full throttle. You can also tell that up to half throttle the batteries get charged and at anything more than half they discharge. So no way the P1 can keep batteries charged on a race track without loosing performance after a few laps.

 

Thank you matey that's very kind of you .

I've always said these cars are so fast and specialised it would literally come down to which car and which track , it's that close .

It's the cultists that insisted one was the word of God and one an "overweight pig" not even "in the same class" , it's an odd view for sure .

 

All I said is for real you can not compare a small company such as mclaren versus giants like Porsche (Lemans record holder) and Ferrari(F1 record holder) and P1 engine is based on a Nissan engine, and do you realize how dumb you look when post false data and lies

 

Thank you so lot, %100 agree you, I hope you will use all your special goodies in great health especially your Carrera GT ( A great car for the greatest drivers!! )

 

Didn't really study the chart. However, not surprising, if true; based off what we've seen (and haven't seen) over the course of the past year.

Hopefully, we'll learn more?

We'll just leave it at that,for now.

 

The Autocar article is a dissapointment, absoloutely no measurements.

Sutcliffe is not above rigging a test to prove his point, take a look at Alpina D3 vs BMW M3 video to see how he had Alpina in a Sport mode with launch control and the M3 was in Eco mode - so he could claim it was a close call 0-100 mph between the two.

 

And yet the brilliant powertrain engineers at McLaren have found ways to avoid the perils you predict. They must be smarter than the average Igor.

The word is 'losing' btw -- given your track record here I really though you would be more familiar.

Not sure if your question was answered so apologizes if this was already explained..

The 918's electric motor max RPM is something like 16,000; the P1's is something like 17,000; so not a big difference but the placement of the motors is quite different. Porsche put their motors on the drive line, whereas McLaren put their e-motor on the crankshaft (not directly of course, probably some small clutch or gearing involved). But that allows the P1's e-motor to work through the gearbox so you get a multiplier effect. Something like that.

 

Believe the max RPM on the P1's eMachine is 17,400 RPM. It may have some additional buffer beyond that - one source cites 18,000 RPM. It connects to the drivetrain through a 1:2 gear fixed to the crankshaft, separate of the transmission.

It's the opposite, Mclaren's E-motor torque isn't multiplied through the gearbox, its transmitted to the wheels through fixed ratio.

Porsche' s rear e-motor torque does go through the gearbox. The front does not, they chose to decouple it at max rpm instead of adding a second gearbox in the front axle. Their reasoning is that the extra weight is not worth the extra performance in speeds above 270 km/h.

Higher e-motor rpm limit does not necessary mean better or more efficient. As Peloton says the e-motor maximum output is 270 hp. The reason Mclaren restricted it to 176hp is not because they did not want the extra ~90 hp but because:
a)They did not want to risk reliability issues
b)I assume that 176 bhp is the best compromise between max power/battery capacity. There is a trade off between e-motor power and battery capacity. High motor output would require higher battery capacity in order to not deplete very fast. This would lead to bigger battery and increased weight etc., in other words the vicious circle of added weight that Gordon Murrey often refers to.

More over the e-motor power does not come for free but it is "drained" as extra load from the engine. I think that Mclaren has done some very clever mapping in order to have the battery constantly charged during no load and part load engine opertion. However in some situations, for example in a very fast circuit where you are in full throttle >50% of the time, you will eventually get out of battery (or you will not have the full 916 hp). Its a simple energy balance equation after all.

Its effective and i believe none of the owners have reported emptying the battery so Mclaren has done a fine job, but i wouldn't call it the most efficient nor the greener way to get extra performance. Then again, its target is to have the maximum performance and electric power does works very good with the P1 turbocharged engine so no arguments here...

mmeng, we know the p1's e-motor is where the starter motor goes, so how is the torque not going through the gearbox?

 

No you are WAY WRONG but why let engineering and physics facts cloud a good argument.............. the 11 mph above 175 mph will not be made up with momentum, far from it when you are accelerating


BTW has anyone seen the La Ferrari at the vmax200 event, it takes over 18 seconds 100-200 mph dashboard time... I think they will not want to show up at a track to take on a P1 or 918 if that is the case

If Ferrari chose the 4wd electric way, could 2 slipping clutches and a small gearbox at the front a la FF plus the 1 e-motor at the crank, have saved some weight compared to the front and rear electric motors of the 918?

 

I hope you will join Le Mans one day

 

We do too!

in what class? LMP1?

 

In 2016 we are hoping to drive our road legal SCG 003 from our factory shown in the latest teaser from our Factory in Turino to Le Mans, convert in the box to Race version, run the 24, convert back and drive to Paris for Dinner, (Garage 56).

We are developing an LMP1 and if we sell enough SCG 003's we're going to build it and race at Le Mans in 2017.

We are continuing on the Road to Le Mans.

 

Don't feed the troll!

Just kidding, Jim

Looks like an Fxx
