Ferrari LaFerrari vs Mclaren P1 vs Porsche 918

Easy, I don't think it could be slower. I should expect exactly the opposite. Especially from
60mph upwards. If they got fresh rubber (remember 950hp to the rear wheels only!:-D), we could have fine numbers then from the start. And I'm waiting
for that as well.

 

You do realize said engineer has spent years of his life developing this system? I don't find his statement vague at all and he is certainly in one of the best positions to know what he is talking about.

Perhaps not in your opinion. In the McLaren when you press on the brake pedal you actuate the brake calipers, not extra regeneration of the battery.

Again, these are assumptions based on what you think you know or your own interpretation of what has been said.

Yes, that happens too. Not disputing this.

From an article written by Steve Davies:

"We were anticipating some sort of KERS (Kinetic Energy Recovery System) to be fitted in the P1, and McLaren describe its function as operating off-throttle when the electric motor provides additional drag torque. Energy is then recovered to the battery which would otherwise be lost (as heat) to the brakes."

Is that clear enough?

Thank you for answering. None of the other Porsche cultists seem to want to join in at this point. Just to clarify, both of those time sheets you posted from top gear and autocar prove my point. The top gear test shows the porsche being 0.2 faster to 60mph and then they are both the same time to 100mph. In other words the mclaren is 0.2 seconds faster than the Porsche from 60mph to 100mph. It's a similar thing in autocar numbers. A tiny fraction I'll admit, but still faster from 60mph onwards.

 

In both tests you mentioned here, 918 was faster even in 0-100MPH, are you drunk?

Topgear test 0-100 5.0 for 918 and 5.0 for P1 , 0-100-0 9.4for 918, 9.5 for p1
This bull.... AutoCar test 5.7 for 918 and 5.78 for p1,

 

K79, you want to act in a way to confirm p1 is faster after 60mph, but I want to make it clear for you that the 918 even faster in 0-120MPH and 0-180MPH for sure, It was confirmed against my two eyes!

 

At least, you are trying to use facts, which is good. Unlike others here…

You are right about the front motor, now it switch offs at 165 mph. But revs much higher too… And have over boost function also… So, in this test it had to pull like “V12 turbo diesel” for another 15 mph making it even more difficult for the p1 to catch up (if the battery was OK or something) …

Now, let me explain one and for all the difference between Race Mode and Hot Lap mode. Because it’s very, very big:

Both modes use e-boost, but the main difference is how it’s OUTPUTED. In RM the ECU gives all the power, but in a controlled manner and never allows the battery to discharge completely. This is the mode, which you have to use on every race track most of the time, because you can turn fast laps all day long. And consistent ones.

The interesting part is HL mode – it has the so called in Porsche language “QUICK OUTPUT” of the electric power. So, the ECU gives all the battery power in the most aggressive manner until it’s completely depleted. And that power is mainly focused on the rear axle for obvious reasons. The implementation of this mode isn’t to switch it and forget about it… The idea is to use it mainly on the long straights and obviously in every drag race. In this way you will gain speed/advantage on the places where matters (straights) and then switch back to RM for the corners and gain batt recharge. Have you asked why it’s activated with a push of a button and not like the other modes?

In a 2 mile drag race even if you deplete the battery in the run, you will recharge it at your way back to the start/finish line for god’s sake

 

Did the 918 in the AC drag race run in Race or Hot Laps mode?

 

Race mode...

 

How do you know?

 

lol, 1mph? Your posts keep getting better and better

 

I'm only going by the published numbers in these 2 tests. It's simple maths. I'll use the top gear times as an example and try and make it simple for you. It shows the porsche being 0.2 seconds faster to 60mph. It then shows them both being the same time to 100mph. Therefore the P1 is 0.2 seconds faster from 60mph to 100mph. The autocar test shows a similar thing above 60mph. Which bit of this are you struggling with?

Is it this? It says hotlap under Race.

 

Watch the video - it's written on the central gauge...
Edit: yes, but not highlighted...

 

You just claimed that P1 was faster than 918 after 60MPH but it is not true for example if a car is 0.2s faster than another till 60 then the same car is 0.1s faster again till 100mph, we can say this car is faster in both 60 and 100mph it's easy to understand just simple!

 

Ahh okay thanks anyway!

 

In my driving experiences with 918 WS at YasMarina circuit there is a huge difference between Hot Lap mode and Race Mode, and it is very questionable for me why the 918 in autocar test was not in hot lap it is because for a drag race Hot lap is the best and most daring attacking mode for 918 in my own experience Hot lap mode was the most spectacular driving experience in my whole life (and as a Carrera GT owner I have had so many spectacular experiences)

 

Yes what you have written would be true if you are looking at 0-60 and 0-100. But I want to make it clear that I am talking about the time from 60-100. Or any speed above 60mph in either printed test.

 

Found the difference between race and hot laps.


For fast laps: “Race Hybrid"

“Race Hybrid" is the mode for maximum performance and an especially sporty driving style. The combustion engine is chiefly used under high load, and charges the battery when the driver is not utilizing its maximum output. Again, the electric motors provide additional support in the form of boosting. Furthermore, the gear-shifting program of the PDK is set up for even sportier driving. The electric motors are used up to the maximum power output limit to deliver the best possible performance for the race track. In this mode, the battery charge state is not kept constant, rather it fluctuates over the entire charge range. In contrast to Sport Hybrid mode, the electric motors run at their maximum power output limit for a short time for better boosting. This increased output is balanced by the combustion engine charging the battery more intensively. Electric power is thus available even with several very fast laps.

For pole position: “Hot Lap"

The “Hot Lap" button in the middle of the map switch releases the final reserves of the 918 Spyder and can only be activated in “Race Hybrid" mode. Similar to a qualification mode, this pushes the traction battery to its maximum power output limits for a few fast laps. This mode uses all of the available energy in the battery.

 

Do you really think that they should have bothered shipping a car that is already sold out from Italy to the UK just because Autocar felt like doing a drag race? Perhaps throw in a couple of supermodels as well?

 

Wasn't the SportAuto test done in Sport mode? So no, it was not because Autocar didn't use Hotlap mode, it was simply because their test results are always slower than expected. Look at P1's first and second tests from Autocar compared to MotorTrend and TG's tests, which were seconds quicker. lol

edited of course, boy...

 

Hahah "it's sold out" is always the best excuse from the Ferrari fan-boys. Why did they threaten Autocar not to use a customer's car then? :-D

 

Don't shoot the messenger. Whoopsy has one and told me it's 265kph for the front motor. He seems very knowledgable about it and is very active here, so I'm assuming he knows what he's talking about. If you can show me Porsche's statement on it decoupling later, I will agree with you. As of right now it's you-said, he-said, and he has one.

Fair point on HL toggling, but the results aren't quite so clear. Correct me if I'm wrong, but RM won't let you run the batteries beyond a certain point. What happens if you're near that threshold and you activate HL? Couldn't you run out of power? Also, what happens when you switch back to RM after having already broken the threshold or run the batteries out? Won't you get reduces output while the batteries get back above that threshold?

Rinse an repeat that a few times and you'll no doubt run into a lot of inconsistencies.

I'd like to point out one more things that is possibly quite telling about the HL theory for this standing mile test: I don't think any test yet has done the launch/drag test with a 918 in HL mode. Even Sport Auto and Auto Zeitung are doing the tests in RM and Sport. Surely they know, have tried, or would have been told by Porsche how to best do this. Why is no one using it if this is clearly the way to do it?

 

No. They shouldn't have and don't need to. But they also shouldn't of threatened autocar with repercussions if they dared to borrow a customer car

 

It's not really sold out everywhere. I'm almost certain you can still order one in China. It's like $4M and it's really not that easy to sell a $4M even in China. There are allocations available.

That's not the point though. The fact that they told AC not to get a 3rd party one "or else" is the problem.

I also find it hilarious that you think it's so much trouble to send a press car from Italy to UK. Stick it on a ****ing truck and it will be there the next day. Hell, plan a week or two in advance and stick it on a truck along with an F12 or whatever other car you're shipping to the UK that week. Where the hell do you think all the cars in the UK are coming from? Did Ferrari start making cars in the UK recently?
