Will love to hear comments from you guys and especially fatboy on the cars and the driving since hes been a bit critical of Chris harris in the past.

 

here you have serious attempts at lap times.

 

Let me just talk out of my ass and say that LaFerrari seems so hard on the front in the fast lap. It just bounces.. And the 918 looks so smooth as a comparison but kinda slow at apex/midcorner compared to it during the rest.

 

Very impressive cars and performance i must say. All we need know is a Koenigsegg at the same track.

The Mclaren just looks so good , visually and on the track

Why wouldn't all three run the same tires??

They are designed for the tires they are delivered on.

When I was a kid, I also wanted a test to end with a winner. And everything should be fair and an even playing field. What this test show is that level playing field is unattainable and just enjoy and appreciate the cars for what they are.

But I'd still have the McLaren given the opportunity (as if...)

Because the Macca and the Ferrari come with Pirellis from the factory (Ferrari with a single spec of tire, Macca with the same one plus a track-focused one), while the Porsche is factory-shod on Michelins and switching to any other tires without suspension adjustments would probably affect its handling quite badly. Particularly since I guess the Pirellis on the P1 and the LaF are not designed to put power to the road through the front wheels, the Porsche being the only (temporary) 4WD car in the lineup.

That's absolutely true on the road, where the nuances of the steering and handling are more important than ultimate grip, but I suspect on the track you'd pretty much sacrifice all that stuff for more grip.

For a mug driver like me it would have to be the Porsche for a track day. The Ferrari for the sound.

For the first time, I could imagine the P1 as a descendent of the original F1 - you can see the styling cues particularly in the door cove/inset dealie ( <- technical term there). I like that.

I would imagine I might be "safest" in the Porsche but my couch-based desire is the P1. And a Koenigsegg. And a Pagani. And a Gumpert. Just so I can say "Gumpert".

Yes, but putting power through front tires that were never designed to handle it would screw with both handling and traction, even on a track. That's the main point: P1 and LaF are overpowered RWD cars with tires suited to that kind of power delivery, the 918 is variable 4WD with tires designed for that specific power delivery.

do tell me how the oarsum power through the front wheels is so hard to handle compared with the braking loads.

The pic looks like a drift event with all that tyre smoke, and tail out. They must be going slowly to do that.

Vid wont play for me, my internet has gone back to steam driven again. Too far from a capital city,, 6km!

Nice that he got straight to the point with the fast lap shootout at the start. Also enjoyed watching the Ferrari as it displayed a lot of body language when driven hard, making it look like it was really on a knife's edge. If it's as rewarding to drive as the video makes it seem, I might have to favour it over the McLaren, which was my favourite before watching.

 

But of course this is all armchair racer speculation on my part. I'll have to wait for my invitation to drive these cars to come in the mail before I can form any meaningful conclusions.

I wonder how much lap time the McLaren's race mode gives.

I wonder how much lap time the McLaren's race mode gives.

 

I've read online that the increase in downforce is huge, like 300-400kgs just from race mode.

 

From reading websites of owners that are very familiar with the P1, they have said that they think the car is severely tire limited when it comes to maintaining lateral grip, as the chassis and downforce configuration is capable of producing much higher loads than the tyres can handle, vs the LaFa and 918. This is even on Trofeos.

 

I'd guess that if all three were fitted and set upwith slicks, the % gain in lap time for the P1 on a track like Portimao would be greater than the other 2 cars, based solely on downforce.

But would it beat a Koenigsegg 1:1? The Swede is lighter and has stupid amounts of power. But the importance of power goes quickly down when you have enough to light up your wheels at all times. So im not so sure the Swedish car would be so much better. if at all. I sincerely hope someone gets to do a head to head comparison on a track one day.

"I've read online that the increase in downforce is huge, like 300-400kgs just from race mode."  Any particular speed, or just a number pulled from thin air?

The number given by McLaren is a maximum of 600kgs at 155mph. From then onwards the car starts to trim downforce as the suspension components can't handle the forces.

 

You're right, I should have mentioned the speed. Very sloppy. Of course no downforce (or only very little) is generated from thin air.  ;)

Hmm. I thought all downforce came from thin air?

No slight intended. Definition of "thin air" has always been:
