Ferrari LaFerrari vs Mclaren P1 vs Porsche 918

This is exactly what I was going to say. Cheers.

 

Why, does LaFerrari's battery last longer? P1's battery lasts for more than a minute and a half at full throttle.

 

After about 100 miles The MC 12, Ferrari 4/5 by Pininfarina, and The Monza Lisa Pagani we're still closely matched...

Jim please post some pics of that pagani! Im dying to see some good shots

 

That is very impressive. I wonder how long the 918's battery last under full throttle? It has a bigger battery pack, but the engine capacity is smaller, hence, relies more on the battery boost. These two cars just fascinating!

 

That's why I'm enjoying this thread.

Not to take everyone seriously is the key and enjoy the nonsense.

Only on one run , they both hit same speed when you look at the fastest time of the day

The beams were at 1.35 miles this time , usually they are at 1.6

 

That name is even cheesier than Laferrari.

 

So on a 0.3 miles (1/2 kilometer) shorter run than when P1 did 209, LaF gets to 207. That indicates LaF would be ahead of P1 in a mile or even a mile and a half drag race.

EDIT: From your edit, make that 0.25 miles (0.4 km). Still enough to overhaul 2-mph deficit I think but given different days, different ambient temp etc., could still go either way. It's close between the 2.

 

Here you go.

KS will be racing our Ben in this who will bring his P1 at Leguna.

KS has also challenged any La Ferrari to show up and race but so far no takers.

KS and Ben are going to work our details.

Maybe I'll pace in P 4/5...

Whoooaaa......that is nice. Love carbon and red leather look

 

Can't believe you still can't see something that's plain and simple.

P1 is normally a 727hp car until the pedal is to the metal, then it's a 903hp car.

918 operates the 4wd system all the way up to 265km/hr, both the electric and gasoline part of the drivetrain contribute even at part throttle. In other words, it car is operating at 887hp mode.

 

Jim, is that the same Pagani press car that's been going around North America? I have seen that exact car not a month ago.

 

Hmm, having just looked at the R&T & C&D articles and the tables within, I cannot find any 60-130 mph times having been measured and that these should be identical at that. I may have missed them but why would both publications conceal them...

 

I want to see your cars in person! What events are you attending anytime soon near nyc?

 

On the road yes.

In my garage no, it's KS's Monza Lisa.

 

Nice chart here. Thanks for sharing. It pretty much shows the battery stays charged when accelerating at a VERY SPECIAL periodic rate between 50 and 240 km/h.

The car's speed variations were obviously optimized and probably computer controlled for max battery life. Notice how they follow every burst with a nicely matched decel to charge. Very sneaky those McLaren folks!

I bet I can wear out the battery.

Whoopsy, that doesn't make any sense. Horsepower is calculated as a function of torque x RPM.

Without looking at the power curves anything else is just speculation of how power is applied.

 

I am monitoring this thread for a long time so maybe it is my time to speak.
I am currently using a well know automotive simulation tool and perform hybridization modelling for the industry. These figures are seem quite familiar.

The figure posted show you do not have E-motor input (full 916hp) during full throttle application

Take a closer look at operation point 50 sec. E-motor initially operates as torque filling (sec 50-53) and then (54 sec and afterwards) while still on full throttle, combined torque equals engine torque and battery charge does not drop. This indicates that you do not get extra torque from the e-motor..

That seems to make sense... the e-motor, as shown in the chart, is not providing torque fill at the higher vehicle speeds. As I do recall, their design goal wasn't highest top speed (where max HP is required).

Can one infer peak horsepower is not 916HP? Perhaps based on that chart. I won't make excuses for McLaren, but I would actually want to see an engineering chart and not a marketing chart of "How KERs works" to really understand, as the latter may be a simplification for "educational" purposes.

Let me see if I can get an answer from the factory and I will post.

 

goplay, I've seen that page, as you may have suspected it comes from a very old concept document that looks like it was for investors or management long before the p1 was developed. Long before engineering.

 

If you watch MT's acceleration run at 5:25, you can see the battery's state of charge on the right and you'll notice that it's being depleted. Only suggests that all 903 hp are being used at full throttle.

NO, not all of the info in the chart is correct. At least one important figure is incorrect and I suspect there are others as well(although I haven't taken the time to fact check the entire spreadsheet).

The 1/4 mile time achieved by MT for the P1 was 9.8 seconds and not the 9.5 sec. time listed in the chart. This error is very significant as a 0.3 sec gap would equal many car lengths difference at the line in a 1/4 mile run.

 

I could post a pic here of some random supermodel; however, that would not prove that I am married to said supermodel...

 

Yes typo but irrelevant.
