Ferrari LaFerrari vs Mclaren P1 vs Porsche 918

The tires were screeching even though it wasn't a hot lap. They likely were gone at that point.

Keeping the batteries cool and shutting them down when they reach a set point is very important as Tesla found our yesterday.

Of course it would be relatively easy for Ferrari build a totally track optimized version of La Ferrari, different suspension settings, set a quick lap and then be done with it. Its highly unlikely most customers are ever going to drive their cars at the Ring anyway and few if any would risk their cars going for ultimate lap times.

 

another Porsche video showing Lieb's first lap at a 7'00 shows the battery charge meter as well and on the last long straight it was down to nearly zero charge...hence the lower top speed

 

Correct.

 

Imagine how slow a second lap straight after would have been. That's a LaF strength, more consistent laps.

 

Always nice having a human V Box amongst us.

 

Yeah but it's not a Ferrari

 

Underground Racing's TT Gallardo is quicker than that...Just look at Youtube videos. Making mega horsepower is so easy these days. Making the car entertaining to drive is quite another

 

Love the Pagani. Koenigsegg is not a bad alternative, but it is still not a Pagani.

 

Twas a joke.

 

If Ferrari do smart marketing they should release a new "2 timed lap nurburgring record category challenge" challenge!

 

None of these will be able to run as fast a second lap.

We ran 6:51's lap after lap for 24 Hours.

The point remains we recaptured 50 HP for 50 seconds a lap from KERS not using the Petrol engine to create charge which takes away total available HP. So far none of these can maintain Total Maximum HP for one lap much less two. So far all are one lap wonders and P1 isn't even that yet and La Ferrari's Ring time remains unknown to date and as Michael said
Ferrari has issues to overcome at The Ring before we will.

 

then you win!

P1 and LaFerrari are road cars.

this obsession with driving around in circles should be directed towards track cars.

 

Do you get up in the morning and go to work?

Then do you come back home at the end of the day and park your car where it started the day?

Then, you drive around in circles all day, too.

 

The Ring is a bit different than driving in circles and that's why Ferrari, Porsche, and McLaren all Market what they have done or will do at The Ring.

If it doesn't matter for road cars, which 918/P1/La Ferrari all are, why mention it in their marketing?

 

You sound like a knowledgable dude. Among the three who do you think would win over two laps? IMO and with good reasons, Ferrari.

 

It's hard to say until we see how fast it can run one lap and what the recharging times are and the effect that the charging has on total output.

So far we know 918 6:57 on street tires 6:48 on non street tires and running out of charge at end of the lap.

P1 7:04 B2G timing and "charged/recharged twice during lap" the effect of "charge recharge" on total output is unknown yet. P1 only charges from petrol. They claim that this occurs when there is "unneeded Torque". Personally I think that isn't present enough on a Hot Ring Lap.

918 charges both by Petrol and recapturing kinetic during braking. Even so it ran out of charge on hot lap. Total available output is unknown for second lap.

La Ferrari. Time yet to be known. Recharges both from Petrol and recapturing kinetic during braking. Total output for entire hot lap unknown and total available output for a second lap unknown.

So far 918 is much faster than I thought, P1 much slower than I though and La Ferrari unknown.

We shall see but I still feel a second lap would be much slower. In F1 systems are KERS only. (Kinetic Energy Recapture) No Petrol is used to create charge. This is a huge difference to these three as whatever F1 Cars get from recapturing energy that would otherwise be lost/turned into heat by braking is "Free" and additive to total output without the need for reducing total available output to charge. P 4/5 C has an F1 system. On the track it operates this way. On the road where there is not enough braking to recharge the driver can select petrol charging. Ferrari and McLaren claim that they use "unneeded" torque and on the road sitting at a stop light that exists at the cost of MPG but on a hot lap I'm not convinced that situation occurs enough to fully recharge without effecting the time you need total output for a hot lap.

 

Ironically the McLaren's greater downforce/grip level may actually hurt it's overall power output over such a long lap on a track with long straights. By recharging its batteries only with "excess torque" I presume it is engaging the charging system almost a form of traction control when the car's systems sense incipient wheelspin exiting corners. More downforce/grip means less chance for wheelspin, and few opportunities to recharge. Which has to kill it toward the end of the lap (or sooner) given that it has much smaller batteries than the 918.

LaF has more power and torque from its big V12, which suggests more opportunities to direct excess power and torque into re-charging that otherwise would simply be controlled/wasted by a regular T/C system.

 

That's the bit I don't understand. Likely these laps are done with TC off. If my guesses are right, the LaF recovers from the electric differential's inside wheel when turning, rather than TC, or on top of it. Also it will do when the throttle is lifted or maybe not at 100%. It could still be enough to keep it charged during pretty much the whole time. 918 and especially P1 with its turbo lag and petrol only recharging, not a chance.

Still I bet you could completely discharge the LaF too if it was possible to start it in top gear for example and flattening the throttle.

 

Another P1 mystery is it's "DRS" on a long straight it should make a huge difference but so far it hasn't.

I think all of these would be faster and a lot less complex if they removed the Hybrid systems, their weight and were simply petrol powered and lighter.
