Ferrari LaFerrari vs Mclaren P1 vs Porsche 918

One thing lithium ion batteries (and turbos) don't like is heat. The P1 has a cooling system just for the battery and its up front to get as much cool air as possible. Same for the turbo charge coolers. It can get quite hot at thermal in which case if the batteries get too hot the car will shut them down to protect them. I've not had that happen to me but I know its possible (probably with any car).

I have a 675 too, track it as well and its a very fun car but I'd be surprised if it could beat a p1 or a 918. The 675 is quick in the turns and can brake later but the P1 pulls so much harder on the straights I don't think you'd ever catch it. On one straight I'm 25MPH faster in the P1, thats a lot.

 

That's a ton, I remember when the 675 came out the internet "experts" were claiming it was close to as quick as a P1. Laughable! The P1 is an absolutely monster. An investor of mine (who has a P1 and 918) has hit 180 in the half mile in his P1, 176 in his 918. 675's are about 160-162 in the half. That's a huge difference.

 

Yes the 918 has better regen but it uses about twice as much electric power in HL mode.

The battery didn't go flat in Salomondrin's test, it died completely and had to go to the garage. In the Nordschleife record lap it goes completely flat and speed drops off leaving it unable to break 180mph on Dottinger Hohe.

Don't confuse terminal speed with time to distance. There are LT's making 10.1s quarters and probably even 9s eventually. Even over a standing km, with AWD greatly benefiting the 918 in a standing start, there is only 0.9s in it. Now on a track, the higher your speed, the sooner you have to brake, so even on long straights, there is only tenths in it.

 

It certainly can't catch the P1 on the same tyres but Trofeo R vs Corsa it's close and I'm yet to see a 918 driver get the better of a good LT driver on a track day. It has several things running against it, which you don't see in magazine comparisons.

1. Can't use HL mode indefinitely.
2. Weight, extra wear on tyres and brakes. Even the Weissach version is >300kg heavier than the LT. Over many laps, that adds up.
3. AWD scrubs front tyres quicker.

Corsa tires on the P1 are a bit of a joke IMO. There is just no grip. The car literally doesn't stop spinning the tires until 85 MPH. I suppose they are Ok for going to Cars & Coffee but if you're going to use full throttle in 3rd gear you might as well be on ice. I took mine off with less than 500 miles on them (rears were shot anyway).

One thing the LT has over the P1 is much better traction control. Its quicker out of the turns for sure.

 

I think the other video from cota with the 675 lt's and 918 was pretty good.

Following vid just demonstrates straight line speed while tracking (i was in the 675. I'll take it from Lieven that I'm not considered a good driver - ). Back and front straight of thunder hill raceway. Doesn't have anything to do with how good it is on track. Note: 918 and laferrari drivers are extremely talented and were right on me (the top left hand corner video isn't to scale (sort of "objects in mirror are closer then they appear).

P1 doesn't drain its batteries completely because it automatically goes into power saving modes before that, which has the same result of slowing it down considerably. It does that because contrary to the other two it always needs some battery power to fill in the massive turbo lag or it would suddenly feel worse than a Renault 4. Clearly remember Mclaren test driver saying the battery was down after a lap at the ring.

 

lieven, who was this driver in the P1? https://www.youtube.com/watch?v=4Vv02WLr3qE&t=156s

Any idea what drive mode they were in? Reason I ask is I don't hear any wheel spin so I'm thinking they weren't in race mode, which would make a pretty big difference.

 

Remember this clearly from myself and frefan who both have p1's and have tracked it quite a bit along with other owners that we know:

There has been no issue with the battery running out on track or otherwise. Typical track day you might do 125 miles.

Another p1 owner did 50 high speed runs down a half mile airport strip the same day and didn't have any issue with the hybrid/battery.

 

50?! That wouldn't be possibly unless it was a private air strip and even then it be so boring by run 10. Good for that owner. Any idea what his best trap was?

 

Check out p1youngin on Instagram . He's a friend of mine and it was at omega airport attack. He posted he did 189 but after getting some more info I found out that it was a little bit longer then half a mile (I did 179 I half a mile which is what I expect a p1 to do)

You're right about the boring part doing it more then 6 to 7 times.

He just got sucked in to giving rides to spectators/friends -

 

What's your point? As soon as you slow down or stop the batteries have time to recharge but claiming that the P1 can do the same record times lap after lap contrary to the 918 is BS. The only one that has a chance to be able to do that is the LaF.

 

I see there is a lot misinformation and opinions, so as a 918 owner and have friends who owns a few P1, let me chime in:

1. P1's battery will never run out. The battery system in the P1 is designed to never run out. It will, however, run low and when that happens, P1 will go into "battery charging" mode and the performance drop off is huge. The car has only engine regen and no brake regen, so the engine is working very hard to charge up the batteries.

2. 918's battery will never run out in Race mode. In Race mode, the 918's battery will ever be depleted, just like the P1. On a track, the 918 will keep on doing laps after laps because the battery is charged up by both its brakes and the engine.

3. 918's "Hot Lap" mode is a bonus that the car has due to its brake regen. In this mode, the engine is taken off the battery charging duty and as such, the engine is allowed to give 100% power as requested. A lot of misconception here from the Mclaren camp. P1 owners think their car gives them 100% juice at all times, this is not true. When the engine needs to double its duty (eg. providing power and charging up the battery), it can never really provide 100% power at all times. This is why Porsche has the Hot Lap mode, which takes the battery charging duty off of the engine.

In Hot Lap mode, 918 will last 3 laps in Big Willow and Laguna Seca (with Randy Pobst driving) before it needs to go back to Race mode. With me driving, it will last 6 laps.

However, the best way to sustain the battery performance on the 918 is alternate between Hot Lap and Race mode during the same lap (Hot Lap during the long straights and Race mode in the slower corners to speed up the battery charging process). With this strategy, I can literally go on lap after lap at Big Willow but come within 0.3s of my best lap time in Hot Lap mode only.

Unfortunately, from an engineering perspective, it's very clear to people in the industry as to which car is the better car overall and which car is fastest in 90% of the tracks around the world. The P1 is a car that is based on the 12C underpinning with the hybrid system added on as an after thought. Don't believe me? Then answer this, why would anyone want to position the heavy ass battery up high in the monocoque in the P1? Look at the 918 and the LaF battery location. They are both positioned on the bottom of the car.

Another thing regarding the Trofeo R tires. Why would anyone slap on tires without the proper "MC" manufacturer certified marking? Because they were never certified from the beginning from Mclaren and they needed to a quick answer to the LaF and the 918. More importantly, why didn't the Trofeo R for the P1 come in the right sizing on the rear?

 

Really funny when someone who doesn't own any of the cars is telling someone who does own the car.


I'll tell you this...get all 3 on the track at the same time among friends, do some laps, joke around between sessions and admire the cars...PRICELESS

 

^^^ And I see the misinformation continues...

 

YES!! They are all basically equal and go about it in different ways. But like I said before, they are just cars, ultimately. To be collected or enjoyed but not argued about over tenths of a second on a race track.

 

Thread should end right here -...but it won't.

 

Really? Which part? The part regarding the Trofeo R being an off the shelf tire without the "MC" marking and in the wrong size on the rear tire? Or the part regarding the placement of the P1's battery high up in the body because the 12C monocoque was never designed to be fitted with a hybrid system?

Both facts were told to me by Frank, when we had a few too many drinks over dinner with Luc in LA.

 

Do you need to own a pig to be able to tell it won't fly? If you bought one thinking it would, on the other hand...

 

I think it's because the LT has tyre widths that are better matched to its power and weight too. The P1 would benefit immensely from 20mm more tyre front and rear.

 

Well we know the P1 can do two 2:17.5 laps of COTA back-to-back and we also know the 918 can't do two 1:29 laps of Laguna Seca back-to-back.

 

I think it's the guy whose name is on the account. There's another video of him on and around Dottinger Hohe here, which is interesting to compare point-to-point with 918 record lap.

Sorry but that's provably false. Go to Dottinger Hohe part. Also ask Ben Sloss for his Laguna Seca data. In fact, why bother, you were there when he posted it first time, yet you still persist with this. It clearly showed the straight line acceleration tailing off in lap 2 and 3.

A quick image search.

Since when did tyres have to be bespoke to be OEM? They are a different size at the rear because of deformation characteristics under load.

Pretty much all of it. All of what you wrote is not only false but provably false. Try again.

 

It's a cast iron fact with video evidence and data log evidence, see jpg above.
