#111939 «Παράνομη στα πρώτα Γκραν Πρι η Ferrari»

Τα γερμανικά μέσα ενημέρωσης θέλουν τη Ferrari να χρησιμοποιεί ένα κρυφό πρόσθετο ρεζερβουάρ καυσίμου στα πρώτα Γκραν Πρι, κάτι που είναι παράνομο.

Παπαριές γράφει το άρθρο.

Αυτό που έγινε είναι ότι μια ομάδα (μάλλον η Ferrari) εκμεταλλευόταν την ελαστικότητα του σωλήνα* μεταξύ αισθητήρα παροχής καυσίμου και μπεκ, "αποθηκεύοντας" καύσιμο. Έτσι, ενώ από τον αισθητήρα περνούσε η σωστή παροχή, τα μπεκ είχαν στην διάθεσή τους περισσότερο καύσιμο ανά μονάδα χρόνου. Έβγαλε οδηγία η FIA μετά την Μαλαισία (χωρίς να κατονομάσει ομάδα) για να τους τραβήξει το αυτί και τέλος...

#112333 Η ελεύθερη πτώση της Sauber και η έλλειψη προόδου της Ferrari παρα το τεράστιο πακέτο αεροδυναμικής δίνουν μια υποψία στο σχετικό άρθρο. Υπάρχει και κάτι ακόμη που το Autosport γράφει οτι εκανε η Mercedes, φρόντισε να πιαστεί με μεγαλύτερη πίεση στα ελεύθερα της Παρασκευής στην Ισπανία για να σφίξουν οι έλεγχοι.

#120966 Η απόδοσή της Ferrari δεν ήταν καθόλου άσχημη σε ρυθμό. Δεν πιστεύω δε ότι υπήρχε θέμα με την ροή των καυσίμων και ότι υπολοιπόμαστε στον κινητήρα γενικότερα. Απλά ο Φέττελ ήταν από την αρχή καταδικασμένος και ο Κίμι το μάμησε (αν και λέει ότι μάλλον είχε ξεχάσει να αλλάξει την χαρτογράφηση του κινητήρα μετά το pit stop και για αυτό σβούριξε).

#194507 In the second of three features on Ferrari's 2015 season, ESPN looks at how the team unlocked a big improvement in performance from its engine.

In order to fully appreciate the progress Ferrari made with its power unit this year, it helps to understand the importance of efficiency under the current regulations. Formula One's V6 turbo hybrids have been criticised since they first started testing in 2014, yet they are remarkable pieces of engineering. After years of running high-revving, naturally-aspirated V8s and V10s, F1 took on the challenge of making something more frugal. What it ended up with was some of the most efficient engines ever made in terms of power per fuel consumption.

"Generally speaking, if you want to find efficiency in a combustion engine you tend to look at diesel engines on huge ships that go at 100rpm or something," Ferrari technical director James Allison explained to ESPN. "They are so slow that they have very little friction and they are so steady in the way that they operate that they can be set up to work on one cycle for optimum efficiency. They work like that for days on end without anyone touching them and they have great big heat recovery plants the size of a house.

"That's the sort benchmark for a thermally efficient internal combustion engine and we've got these little screaming V6s that don't just sit there at 100rpm, they zap up and down, go round laps and fight with one another on the track. Yet they are as efficient, in fact you could argue more, than this one-purpose, solely-designed-for-fuel-efficiency engine that has got, on the face of it, a lot more in its favour than what we do. It's very, very impressive that these little racing engines can achieve that level of fuel efficiency."

Of course, beating a ship engine for efficiency is not what Ferrari set out to do over the winter, its target was to close the 50 bhp gap to rivals Mercedes. Yet the strict fuel flow limit in F1's regulations means the only way to unlock more power is to get more energy from the fuel at your disposal.

"It's a really strange formula to get your head round," Allison adds. "I've often seen non-F1 engineers look at me like they don't believe me when I tell them this, but everyone thinks more power means more fuel consumption, but this set of rules is absolutely not set up that way. More power means less fuel consumption in this sport. The way you get more power is by making a power unit that has less fuel consumption.

"Everybody's fuel flow is limited to the same value and every single car on the grid is going down the straight with their fuel pump pumping at exactly the same number of kg per second, so with that fixed fuel flow, the more efficient the engine is the more horsepower you deliver to the wheels.

"The more horsepower you deliver to the wheels, the less time you spend on the straight because you get to the end of the straight quicker and that means the less time you spend at the full fuel flow on the straight and the less fuel you consume.

"So fuel efficiency delivers you lap time in two ways, it both gives you the normal thing of extra horsepower at the wheels but also you the added benefit that you use less fuel. That means at some of the races that are very tough on fuel consumption, you are not having to lift off at all.

"A less powerful engine, a less efficient engine, will have to lift off at the end of the straight to save fuel, whereas a car with an efficient engine can keep the foot planted until the end of the straight. This formula is all about efficiency and that is what it was designed to achieve."

Early in 2014 Ferrari already knew where its power unit's inefficiencies were. A decision to prioritise aerodynamic packaging at the rear of the car meant the team compromised some aspects of the engine, including the turbocharger and the MGU-H part of the energy recovery system. It had been a conscious decision in an attempt to maximise downforce, but it did not pay off and left the team a long way off the pace at most circuits.

A ban on in-season engine development in 2014 meant Ferrari was stuck with its decision all year, but it could start making sure it rectified the issues for 2015. Alongside improvements to the internal combustion engine, a larger turbocharger was fitted, which in turn produced more energy for the MGU-H to recover. More energy for the MGU-H meant more power to deploy on the straights, thus shortening the time spent on full throttle and saving more precious fuel. In short: Win, win, win.

But in order to maximise the advantage of its new, more efficient engine and energy recovery system, Ferrari needed improvements from fuel supplier Shell. Although fuel is at the very core of the upward spiral of efficiency explained above, Allison admits the team overlooked the importance of its partnership with Shell in 2014.

"The new leadership on the Ferrari side was very keen to bring the power of all their technical partners and the engineers inside Ferrari to try to make sure that we were competitive in 2015," Allison says. "I think Shell were always waiting for us to be involved in that way and the change was on our side to open our doors."

In total Ferrari and Shell claim the performance gain from fuel upgrades alone to be worth 0.5s a lap and an average of 30 seconds per race. In the fight against Mercedes those are big numbers and worth roughly 25% of the overall performance gain Ferrari has made with its power unit this year. Pinpointing exactly when Ferrari levelled up with Mercedes is harder. The opposition points to Maranello's big combustion upgrade at the Italian Grand Prix.

"Since they introduced the updated engine at Monza, I would say that they matched us in terms of power and efficiency," Mercedes' team chairman Niki Lauda said towards the end of the season. "The 20bhp advantage we had is now gone. Now we are at the same level of power. We know for certain because of the reference we have."

But Allison insists it was a gradual improvement from all sides of the engine programme rather than one single step.

"Monza wasn't the magic bullet in the season, it was several steps, all of which were very useful. We would have made a step forward without this, but Shell's input was very useful."

And that is the best way to look at Ferrari's progress this year. The realisation that it had got its priorities dramatically wrong at the start of the new engine formula in 2014 triggered the need for change that snowballed through the winter to deliver a big step change in performance for 2015. From there constant progress has been made with the efficiency of the power unit to level up with Mercedes by the end of the year. The next step, and undoubtedly the hardest yet, will be to move ahead in 2016.

The final part of ESPN's analysis of Ferrari will assess the team's chances of closing the gap to Mercedes next year.

#194814 In the final part of ESPN's look at Ferrari's 2015 season, we analyse the Italian team's chances of taking the fight to Mercedes in 2016.

Now the dust has settled on the final round of the season, Formula One's attention has shifted to 2016. In truth, the teams' factories have been focused on next season for several months, but with the on-track action over for another year, the news agenda is finally catching up. The main talking point is clear: will Ferrari be able to take the challenge to Mercedes in 2016?

It's rare that two rival teams will agree on anything in F1, but at the end of this season both Mercedes and Ferrari estimated they were level pegging on power. Both sides analyse GPS data and top speeds to measure each other's progress, so the fact they came to the same conclusion suggests their power outputs are as close as they have ever been since the start of the V6 turbo era in 2014.

"Sadly you never have the luxury of putting your power unit and their power unit on the same dyno and having a dyno-off to find out who's got the most and the way you judge the opposition's power is a little more imprecise than that," Ferrari technical director James Allison explained to ESPN. "You could see from space last year we were nowhere, but with the sort of methods you can use to analyse, you can see that in the battle of Mercedes versus Ferrari we are there or thereabouts this year.

"But it doesn't mean we are resting on our laurels they are not going to stay still and there is much more to be done. But the power unit team and technical partners of the power unit team have had a remarkable 12 months to drag Ferrari up by its bootstraps to get to where we are today."

Mercedes' power output has not stood still this year, so not only has Ferrari closed a gap of roughly 50 bhp that existed in 2014, it has also matched the moving target of Mercedes' own development. After two years of domination in 2014 and 2015, Mercedes team boss Toto Wolff admits his team is increasingly worried by the growing amount of red in its rear-view mirrors.

"Ferrari has made a big step from 2014 and considering the results we think that could well be the case for 2016. We take the Ferrari competition and threat very seriously. Competition is good and important for F1 for there to be more going on at the front. Ferrari is our best frenemy."

Many of the technical improvements Ferrari made this year were relatively low-hanging fruit. The mistakes of 2014 were easy to identify once testing got underway, but due to the FIA's freeze on engine development they could only be rectified for the start of 2015. Reproducing a similar step in performance over the coming winter will not be so easy.

What's more, the early signs suggest Mercedes will make a big step of its own in 2016. Rather than chase out-and-out horsepower in a season it had already sewn up, Mercedes' big in-season upgrade at the Italian Grand Prix was targeted at creating a prototype engine for 2016. The upgrade still brought performance, but its full force will not be felt until the opening round in Australia next March.

In order just to remain in touch next year, Ferrari must make sure the wave of development that carried it back to winning ways in 2015 continues to offer performance in 2016. Allison is confident there is still enough unlocked potential in the regulations to do that, but admits it will be tougher than last year.

"I think the regulations are still relatively young, the power units are already really impressive things, but the regulations are young and there is more to be had," he explained. "I think it was more straightforward last year because once we had figured out where the gain was at, it was easier for us to correct our error, but us, Mercedes, Renault and Honda are all working with a young set of regulations where there is opportunity.

"Our competition is certainly not going to be resting and I hope that we are not either. I hope that we can make steps next year, not only in our own absolute power -- that much is guaranteed -- but also in the hunger and skill of our people that will be enough to stick our noses in front."

Although the first test is still over two months away, Ferrari has made its targets for 2016 clear. Team principal Maurizio Arrivabene did not hold back in a recent press briefing, telling reporters "If you want my honest expectation, it is not to be closer to Mercedes but to be in front of them". Race driver Kimi Raikkonen says the early numbers from the factory look promising, but is not willing to read too much into them until the car hits the track.

"If you think what we have done from last year to this year, then we are going to make another step next year," he says. "I have 100% trust in everybody and we can see the numbers, but until we put the car on the circuit we will not really see where we are.

"And even if we are really happy and everything is like we expect, we don't know what the other side has done. Of course we are going to be stronger next year, but will it be good enough? Only time will tell."

But to focus too much on the engine would be a mistake. Ferrari may have matched Mercedes for power this year, but Raikkonen was still 0.814s off Nico Rosberg in the final qualifying session of the season in Abu Dhabi. Most of that gap appears to come from the chassis and aerodynamics. Allison says one of the biggest misconceptions around the current regulations is that Formula One has become an "engine formula".

"It's not an engine formula. You can say with absolute certainty it's more of an engine formula than it was at the end of the V8 era, because with frozen engines what could you do? But this formula that we enjoy today is much more like F1 used to be.

"Mercedes are not beating the other teams just because they have got some rocket ship engine, they have got a very good car. Ferrari has got the challenge of having to improve on all levels to beat them. The power unit is going to be a key part in that, but the chassis is also going to be a key part in that."

At this early stage Allison is not willing to give any more away about Ferrari's plans for 2016. Just like its rivals, the rest of us will have to wait until pre-season testing to see if all that hard work pays off.

Former Ferrari president Luca di Montezemolo has defended Fernando Alonso over claims from its current bosses that the Spaniard was never as big a team player as Sebastian Vettel.

Montezemolo's replacement Sergio Marchionne told Italian media during his regular Christmas press conference earlier this week that Vettel was more entrenched at Ferrari than Alonso ever was.

"At the beginning of his adventure in Maranello, Vettel was already more a 'Ferrarista' than Alonso was after five years with the team," said Marchionne.

"He is a great boost for us. At the Christmas dinner with the team, he spoke in Italian – after having prepared his speech and learned it almost by heart.

"He has joined Ferrari immediately with the right mindset."

Speaking at the Autosprint Golden Helmets Award on Tuesday night, di Montezemolo suggested that such comments were unfair, because they did not take into account the challenges that Alonso faced when at Maranello.

"Alonso would have been more [a Ferrarista] if Ferrari, in 2010, had won a world championship that was easier to win than to lose," said di Montezemolo.

"And if in the last race of the season you lose the world championship twice, these things need to be understood."

Despite remaining loyal to Alonso, di Montezemolo has also high praise for what Vettel has achieved at the team since his arrival.

"He is certainly a guy who has shown great ability to work for the team," he said. "I think it is crucial for the growth of the team, of its morale and its unity.

"But he needs to not do it with words, but with facts, like Michael [Schumacher]."
