Ova analiza od J.Allena je malo nezahvalna jer se uspoređuju Hamiltonove simulacije sa početka testova u prvom tjednu, sa onim od Ferrarije u drugom tjednu..

sad par citata iz talijanskih izvora:
The Horse team is building its strength on the new engine 062, much more efficient than in 2016. Most progress power unit can be seen especially on turbo and on the ' ERS that gives a charge of electricity more effectively with' MGU- H , having lowered to 3.5 bar, the maximum pressure value.
With the latest engine predisposition, Vettel and Raikkonen are able to unleash on the track the electrical power (max 160 horses) for a lap time by almost 50 seconds , a time span much longer than what was happening in the past few seasons. To make the engine even more powerful we also think the new Shell petrol, characterized by reasonable anti-detonating elements that offer the reliability that Ferrari has always sought. These elements, which have allowed the Maranello team to complete both sessions of tests with the same engine, no change ever .
Signal, which feeds the smiles among men in red, forced in the past to struggle with both the weaknesses of the power unit and with the usual problems with the gearbox, this year finally (apparently) resolved. Any situation that increase optimism ahead of the new season during which Ferrari will have to demonstrate that they have learned the lessons of the past: forbidden to turn a World other with zero victories, Marchionne has already spoken out.

Analysis of the test in Barcelona: Ferrari is really the fastest? -izvor
Surely the situation in Maranello is much more positive than we expected after very reassuring rumors before the tests. The SF70H proved immediately a very reliable car and in 8 days accused only small teething problems. E 'managed to run quite regularly encountering no special setup problems. The car designed by Allison and then developed by Remember with Byrne's supervision is a car that has proven to be quite simple to take to the limit and remember, vaguely, the characteristics of the "old" Lotus of the 2012-2013 vintages.
Compared to 2016, the first thing we noticed is the improved traction thanks to the excellent work done both mechanically and on the Power Unit . Power Unit that has improved a lot both at the level of maximum power both in delivery . Only on rare occasions, when the tires were very worn, the SF70H, it was nervous when pilots put your foot on the gas. Compared to 2016 is not much improvement in the inclusion of the car curve that seems to accuse of a slight understeer which manifested itself mainly when the car was driven by Raikkonen. We know that the Finnish driver prefers the cars with a very precise front and in this area the engineers at Ferrari will have to work again. Understeer is clearly manifested in the third sector, characterized by medium slow corners. The SF70H could not walk the same narrow lines, however, were able to have both Mercedes Red Bull.
Another weakness of this SF70H seem to be the curbs. The car seems to "absorb" much worse than the Mercedes thanks to the suspensions can not turn around to attack them.
In fast corners the SF70H has performed well , proving very stable and fast, especially in challenging curve as the 3 and 9, although the lines were not as tight as those that could do the drivers of Mercedes and Red Bull.
To demonstrate the understeer problems of Ferrari SF70H we analyze the best lap Raikkonen compared with that of Bottas.
Turn 1 after the long main straight. Pilots arriving at speeds of 330 km / h and off very close to the first corner. Is known as the Mercedes of Bottas manages to be very close by putting the right front wheel over the curb. Raikkonen, however, fails to make such a tight line as the countryman of Mercedes.

Curve 3, in this season, we deal in full and even here we see that the lines that manage to keep the Mercedes W08, compared to SF70H, are much narrower.

Treći zavoj
In curve 5 is known, once again, the difficulties of Raikkonen to stay tight in this corner while Bottas managed to pass very close to the curb.

In curve 10, the Ferrari turns quite wide from the curb while the Mercedes manages to make a line that only the W08 can travel. Same thing in Turn 12 where the Mercedes passes very close to the curb while Ferrari is forced to greatly widen the path.

The Red Bull , according to the pre-season indiscretions, had to be as close to Mercedes team in Barcelona but this is not seen. The main reason for the failure of performance of the RB13 is definitely in the Power Unit that during the eight days of testing has accused several problem to the MGU-K as well as the turbine that, according to our information, it should have been splitted compared to the compressor following the philosophy Mercedes has undertaken since 2014.
These problems have forced the Power Unit Milton Keynes engineers to use very quiet mappings . This you could also hear "by ear" as were those who went lower speed and not exploiting the full potential of MGU-K. S ccording to estimates made by the team Red Bull, the French Power Unit would pay even 25-30 hp compared with that of Mercedes and Ferrari in this beginning of 2017 seems to be able to match the performance of German unity. The conditional is necessary because, during these tests, has never been able to enjoy a ride at full power of the Mercedes W08.
In aerodynamics, the RB13, continues to be a car rather simple and, if we exclude the nose pierced, they are not given the technical "imaginative" solutions we expected from Adrian Newey. It should be said that the Red Bull team has planned a day filming right in Barcelona on Sunday and is not at all impossible that only at this juncture we will see the true RB13 who will race in Melbourne.
Home- Mercedes , even in this 2017, they did a similar job to what we had seen in 2016. Unlike last year have focused to turn a lot with the soft compound , while in 2017, they were mainly concentrated in the media. This is because the soft rubber which will be the more you will use this season , as, provides excellent performance and little degradation.
Mercedes has shot for all eight days of testing with lots of petrol in the tanks , and despite Hamilton and Lauda statements, the team are not at all worried about Ferrari's performance. According to their projections on low fuel and ultrasoft tires could run in 1: 17alto . The work in Mercedes home was mostly trickle in r esearch of the ideal of the car setup .
Unlike everyone else on the track team were the only ones to take to the track a great evolutionary package , and therefore, they had to test it, and change some of the machine settings. In addition to this they have had problems especially with the new fund that due to vibration has accused some damage. Damage that was repaired reinforcing it with "carbon skins" in the offending areas. These issues have lost valuable time for engineers in that, because of these problems, they could not see the track the same data that riscontravano from the wind tunnel and CFD. Data which are then returned to mate after the reinforcing interventions made during the night between Tuesday and Wednesday.
For Australia is still expected changes on the W08 and the Ferrari there will be no big changes compared to the car we've seen in the last two days of testing.
After we focused on the work of the first three forces on the track let's look to the work of the other team. Tests for Williams were quite positive. The car, although very simple, has proved competitive and reliable. Seeing performance on the track Williams seems far from Mercedes, Ferrari and Red Bull, but seems to have a good margin on other cars.
The other team, Toro Rosso, Renault, Force India and Haas seem to be roughly on the same level and therefore it is difficult to give more precise figures.
On the bottom of the standings, Sauber and McLaren Honda. See Sauber in the queue is definitely not a novelty, because, one might well expect little from a team equipped the Ferrari 2016 Power Unit.
The real surprise in the negative, is definitely the McLaren which seems to be back into the abyss of 2016. The Power Unit Japan continues to be unreliable and, when it turns, s t seems not even have power . When Alonso and Vandoorne turned the maximum speed was less than 20 km / h than the other. In all these days of the Power Unit tests used by McLaren were well 6.
In 2017 this was expected a big leap from Honda two years of experience. Leap in quality that, at least for now, has not been seen. The car remains a great question because it is not possible to evaluate it with a power unit of this level. On a positive note on MCL32 is the behavior when changing direction that seemed to be pretty good.
