2015 Pre-season Testing

[godlameroso]

Remember that part of the lap is spent harvesting energy, you can't really determine much from these times, they might have been checking the way the batteries harvest energy, someone could have made a mistake, or maybe they're seeing if they can go x amount of laps on x amount of fuel and have to adjust lap times. You really never know.

Apologies if this has been posted already but here is PW / Craig Scarbs breakdown of the First Barcelona test:



F1 test update 3rd test, Barcelona Day 1:

[WaikeCU]

Williams-Lotus-Ferrari stints on medium compound. Ofcourse we dont know the fuel.
The lap times for Romain Grosjean's latest stint on the medium compound: 1:28.4, 1:27.5, 1:27.9, 1:27.9, 1:28.5, 1:31.1, 1:28.8, 1:30.0 and 1:30.8.

Kimi Raikkonen is on a longer stint on the medium compound, setting these times: 1:27.4, 1:27.4, 1:27.7, 1:27.6, 1:27.6, 1:27.7, 1:27.8, 1:28.2, 1:28.2 and 1:28.3.

Felipe Massa has returned from a longer stint on the medium tyres, setting these lap times: 1:28.1, 1:27.8, 1:27.7, 1:28.3, 1:28.4, 1:28.7, 1:29.1, 1:28.9, 1:29.1 and 1:28.8.

I recall Hamilton doing this in the morning yesterday on medium tyres:

Hamilton is pushing on, on the medium rubber. Since posting his 1m25.192s, he's completed a 1m26.040s, 1m25.947s, 1m26.224s, 1m26.063s and 1m26.480s.

What does that tell us...

I think no body is comparing Kimi run with Merc one. Merc is fastest its sealed. What every one looking for is where do the Ferrari stands against Williams and Others

What does that tell us...

A half tank run over a shorter distance vs. ¾ tank runs over a slightly longer distance.
Why, what does it tell you?

It's still a guess on how much fuel they got onboard and I don't even know how many laps Hamilton has put in on that set of medium's, but it would be hard to think they are on low fuel. I think what matters most for Mercedes is a full fuel tank performance. Q3 times are set with a full fuel tank and that's probably the hardest part on Saturday qualifying for them. For Mercedes it's the most important thing to find their optimal performance on full fuel range. I believe that's where they got competition with Williams, since Williams have the best fuel usage throughout the race when we look back in 2014. If Mercedes can leave their competitors behind as early in the race, it would be easier for them to manage the race, the car in the latter stages. That's why I think they are practicing on their full fuel range pace.

[Vasconia]

It's funny how people keep mentioning Force India, they haven't even run their car.

True haha, we dont know what they can do but perhaps some people think that can have a good car taking into account that they have a Mercedes engine. Plus Force India usually starts the season in a good shape before the development war starts.

By the way, the long runs of Ferrari look good.

Just to inform you: Q3 times are not done with full tanks, what would give you that Idea?
Secondly, full tank times around here is 1:31 to 1:29, 3/4 tanks 1:29 to 1:27, Half tank; high 1:27to 1:26 and1/4 is 1:26 to high 1:24...

I thought it's prohibited to fuel by the end of Q3 and the start of the race.

Furthermore, no refuelling is allowed during Q3 - hence drivers participating in that session must start the race with whatever fuel was left in their car at the end of Q3. If a driver makes it through to Q3, but is then unable to compete in the session, his team must inform the FIA immediately of how much fuel they wish to add to the car.

Refuelling when a race has been suspended is forbidden unless a car is already in the pit entry or pit lane.

Sorry what , From what i hear and see Q3 is done with almost minimal Fuel on the tank and to get out and out fast time from the car since 2010

Thanks for lighten this up. Guess I was reading the wrong regulations of probably the wrong season somehow.

Nvm my few posts then. I think Mercedes could be fueled a bit lighter than other then. We'll see...

[f1316]

I think you must be looking at an old regulation. Current regs have them on the smallest amount of fuel possible to finish Q3 and get back to the pits.

We obviously don't know who's running what fuel loads, but "Chene_Mostert" is likely pointing to the fact that the run of Hamilton's you're looking at is a 6 lap run as opposed to Kimi's 12 lap run; again, we can't tell for certain what amount of fuel each car has, but it does point to Lewis being lighter.

And no, Merc being fastest car is not 'sealed'. I think it's fair to say that it's very likely they'll still be ahead - possibly far ahead - but there's absolutely no hard evidence that *confirms* this.

[Chene_Mostert]

You need to get an updated version of the regulations.

[WaikeCU]

Yeah I know, but I entered 'F1 Q3 fuel' and ended up on the F1 site, probably and older version of the regulation. I wonder why that page is still available.
