Ferrari LaFerrari vs Mclaren P1 vs Porsche 918

the old one speaks about KERS, this should be the latest one (which speaks about IPAS)

EDIT: ignore what I said above: they are the same & the latest charts from mclaren.

What I don't understand from these graphs is that from 41-46s, while on full throttle, the battery goes down by around 20-30%. But if you look at the interval 51-59s, the battery gets depleted 100% in only 8secs burst?! It doesn't seem to me that P1's battery would last half as much on tracks like Big Willow compared to the 918.

 

Simple, because Launch mode was engaged. That tells the ECU to give it everything it has. The P1 will be in 903 mode for the duration of the the run until the pedal is lifted or battery depleted.

 

GoPlay,

Actually that makes perfect sense if one is not a blind fanboy of McLaren but one that want to dig down to the bottom of stuff regardless of brand allegiance.

The graph tells the story that the e-motor in the P1 is not an active component, it is only called on as needed. Which means the P1 is a 727hp car but has a 176hp shot of nitrous on standby.

As you have found out from another site, I was an early depositor of the P1 and the 918, and somehow down the road I canceled my P1 order due to a variety of reasons. One of those is that I found out about the truth on the P1's drivetrain and the whole car's origin. let's just say I met an engineer from a unnamed company during a layover and had a VERY VERY long chat. I was asked to agreed to a informal NDA, gentleman's word in British terms, which I had kept to this day, I won't actively disclose stuff but I will only echo if someone else disclosed first.

I do not diss the P1's performance, I think it performed fantastically, the aero tech is especially trick. But just that in my eyes it's not worth the price McLaren is asking and the tech is lagging behind what Porsche put into the 918.

I have since had a go in a P1 and couple of my friends had also taken delivery. Inside the car, the sensory overload is unreal, if i hadn't done my research, I swear I would be singing the same tune as Chris Harris & Co. The P1's driving position is very in your face, the sense of speed is very enhanced.

Despite what I have said about the P1, I am still very much a fan of McLaren and the F1 is still the holy grail of sports car which I still dream of owning and I still miss my 12C which I dearly loved, that platform is just about the best in our generation, or ever.

All cars are designed with compromises, Walliser designed the 918 with the compromised on the highest end of the performance envelope, he forgo high end hp for more low to mid range 'punch', hence the disconnect of the front motor above 265km/hr. McLaren forgo a full time hybrid system in exchange for a lighter package, relying on the mother of all monster V8 to provide most of the grunt and the trick aero to provide the performance, that strategy clearly works as the P1 is a fantastic and agile machine to drive. Even me as a 918 owner in waiting have to agreed that the P1 has more sensory overload than the 918 in full furry with the top off.

Ferrari also had their trade-offs, I never really bothered to investigate as initially the LaFerrari was out of reach for me. Now that I am on their radar it will be a completely different story for another time.

 

It's very simple, not sure why you're complicating it like that. Car has 903 hp whenever the driver is asking for it (except when the battery is depleted of course), but I don't understand why you would need full power if you're not at full throttle.

 

Ture !

We better ask them to delete the rpm red line and the word "combained"

Mbn

 

I come from a background of drag racing, for that, it's either all motor or juiced. And if juiced, how big the tank is. That tells the tale of whether one car will run 9s all day or 9s for a couple of runs and then 11s.

For some, it doesn't matters, for myself, it does matter if a car can last a longer time. i would take a car that will do 7:02 all day at the Ring than a car than will do 1 lap of sub 6:57 then revert to 7:15 the rest of the day. Absolute speed is worth nothing if it can't be repeated for verification.

 

correct, anyway based on Fastestlap P1 speed at the end was 152mph, this is akward! (for 918 its 145Mph)

and if the other informations are correct, then we should take an another look to P1^

 

So whoops are you going to the ring with your car? I'm planning to go next year again as a spectator, would love to see you run the 918.

 

FWIW: Motor Trend test; if you didn't know already, wasn't a proper test.

How many times does this need to be mentioned. Even Motor Trend points this out, says this.

You don't hear people bringing up the old, beat up Texas drag strip run for the 918?....So try again.

Maybe you would want to go with the Autocar example? They're aren't many regarding the P1 to choose from.

 

Precisely. I also noted that 60-130 mph times cited on the spreadsheet for the 918 against the R&T & C&D tests were (as far as I could see) not recorded, odd also that these should be identical at that.

 

As you know I am getting both so I have 2 dogs in this hunt!

At the end of the day, all these cars come at it from different starting points and with different compromises. I won't defend any of them but will point out erroneous info for fanboys and detractors alike.

 

BTW, I haven't forgotten your earlier post comparing yourself to a journalist. You just reminded me that that is very amusing on so many dimensions.

 

It was with a full tank of fuel, coming from a respected journalist and V-box recorded. Autocar's tests are always way too slow. Look at the Veyron results.

650S managed to hit 300 kph in slightly over 24s in Autosport's test which is slightly slower than Autocar's P1 test. I'll leave it here.

 

In both runs though the Ferrari finished in front.

 

I think we are missing something important or maybe its the wording.

Engines don't produce their max hp throughout the rpms. Even if the electric motor adds full power it won't be a 903 car throughout the rpms. Same thing goes for the lf and 918.

If your running a purpose built big juiced motor wouldn't you need to lower the compression? Which in itself is a compromise as it would run terrible without nos.

What I have heard from the p1s testing is that you will run out of fuel before running out of juice in the nurburgring if you decide to run continuous laps.

 

Are you implying that the electric motor is not active at anything less than full throttle? Otherwise, I don't at all follow what you're saying.

 

But, but, but when a poster seriously states a fact and then repeats that fact, they must be stating I believe such. Its a little odd when they then alter that fact to suit the newly proven state of affairs. Posters were stating it produces 903 bhp in all modes, at all times. Now they are stating that it doesn't matter because it has been pointed out that it doesn't and nor should it....... Its a bit of a pointless argument.

 

Which mode doesn't the P1 produce 903 bhp other than E-mode?

 

Thanks for the info bill. Would you be aware of what mclaren is claiming the p1s weight to be? In the owners manual laf is mentioned as 1490

 

P1 has been weighed at the Pagani factory and is reported to be at 1,570 kg with a 70kg driver.

 

Hi Doom
The owner of the laf is on pistonheads he said this year he beat the veyron in both races and had a higher trap speed

 

About the same for them then. Wish some owners would put some vbox's on their cars and go for it. No magazine is going to give us a proper factual comparison. Simply won't get permission

 

Only when 'Boost' is activated, that's where the IPAS button on the steering wheel comes into play.

 

Charge, neutral, park, valet and reverse. We have been cheated how dare they
