Formu1a.uno - In Monza, McLaren took what Ferrari wasted in MonteCarlo.

Like every edition, Monza is able to offer various ideas of a technical nature, as well as give emotions on the track, and for this reason, it is one of the most interesting events on the Formula One calendar.

The temple of speed has always made it possible to see cars with the most atypical aerodynamic configurations on the entire calendar, precisely because of the characteristics of the Monza circuit.

The very long straights, separated by violent braking with slow chicanes, favor single-seaters with very low, almost neutral wings, which are practically not seen in any other races in the world championship.

The 2021 edition, if we want, was even more particular than the past race, since the current season we know is a transitional and conservative one for many teams, which are already technically and economically projected to the development of the 2022 wing-cars.

Focusing on the fight for third constructors place, Ferrari and McLaren expected a different Italian Grand Prix, almost the opposite, with the English team very convinced that the technical characteristics of the circuit matched well with the MCL35M, vice versa for Ferrari.

However, both teams performed above their expectations, with McLaren delivering a masterful overall performance, not just in the race, but throughout the weekend, and Ferrari finishing in second place as a team in terms of points collected.

ITALIAN GP FOR MCLAREN

The return to success after 9 seasons (with a brace for another) was by no means accidental. It is true that the contribution came from the retirement of the two championship leaders Max Verstappen and Lewis Hamilton, but both McLaren's were always close to the top positions.

The Orange team in Monza laid the foundations for a possible podium already in qualifying for the sprint race, showing a potential top. The final victory was the culmination of a perfect weekend, in which none of the drivers or mechanics made any mistakes.

At a technical level, the MCL35M of Ricciardo and Norris was equipped with a rather light set-up, one of the most aggressive among the various teams

The car designed by James Key is known to be a single-seater with great efficiency, as is the Alfa Romeo and is home on fast circuits. The trump card McLaren played right on the set-up, further exasperating its strength, adopting an extremely unloaded rear wing.

The mobile flap of the DRS in Monza had an extremely reduced chord, while the main profile was almost neutral. This made McLaren extremely fast on the straights, managing to be almost impregnable even for those following in the DRS zone.

In this regard, it is important to remember that the wake is all the more important when the wing of the car in front is large.

It should also be noted that the MCL35M is equipped with a Mercedes Power Unit, and the extra horsepower of the engine designed in Brixworth, first brought to the track between Silverstone and Hungary on the official car (Mercedes W12), by Spa also on customers, (McLaren, Williams, and Aston Martin) all met in Italy.

“The engine is a great engine and it helped us a lot,” an insider from McLaren told us.

The long-wheelbase also gives a certain stability in the fast corners, such as the Parabolica, where Ricciardo and Norris always managed to slightly open the gap from their pursuers.

Even on the front axle, James Key's car has adopted a very unloaded wing, with the last two flaps (the ones that allow you to adjust the incidence) substantially cut to reduce the resistance to advancement to the minimum possible.

With the double at Monza, McLaren returned to occupy third place in the constructor's championship with eight races to go, effectively managing to maximize the result in the only seasonal chance of victory.

ITALIAN GP FOR FERRARI

If it was a great celebration at McLaren in Monza, the same cannot be said for Ferrari.

However, the Maranello team was aware of the difficulties that would arise on the Monza track, the post-weekend statements by the two drivers, as well as those of Mattia Binotto, were clear.

The team arrived in Monza with the awareness of not being able to give great joy to the "fans", but with the certainty of not repeating last year's horrible performance with the SF1000.

The SF21 is a car that compared to last season is a clear step forward.

We have often emphasized that, despite the various limitations deriving from the freezing of the macro components, the work done by the Maranello technicians was excellent.

Since the SF21 was a close relative of the SF1000, there were many limits to be corrected: power unit, front axle, and rear instability. The latter was also chosen because that macro area of ​​the car was the most limited by the 2021 regulatory changes and where Ferrari thought and hoped to make the most profits.

The Monza track, on paper, did not go very well with the SF21 due to a matter mainly related to the Power Unit: the 065/6 Evo proved to be a clear step forward compared to 2020, however it still pays 25 HP from the most powerful Mercedes power unit, 15 HP from Honda.

Some problems in terms of reliability were seen on Friday in Charles Leclerc's car, with the Monegasque having to mount the old unit (the number one unit). Monza is a very demanding track for engines, where you are full throttle for almost 80% of the lap.

The updates regarding the hybrid part are eagerly awaited on the Ferrari, ready to be implemented in Turkey, if all goes well. In fact, some hybrid components from the past season are still present on the current 065/6.

Mattia Binotto spoke of "change in technology from the hybrid side" because the red will be increased so significantly, as anticipated by Michael Schmidt AMUS,  the voltage of the electrical unit, approaching the 1000 V threshold, a value with which, Mercedes has worked with for a couple of seasons already.

In general, the higher the voltage, the higher the efficiency of the entire system. This will also reduce the size of the components.

Hence the words of Binotto regarding “hazardous materials” for which “formal approvals and certifications are needed”. Also to be simply transported.

If it weren't for the Power Unit appearance, Ferrari at Monza could have had a better performance without a doubt. It remains to be stressed that overall the weekend was anything but a disaster.

The Monza circuit has characteristics that were not so detrimental to the Italian car, beyond the long straights. Ferrari has always behaved discreetly in rear limited circuits, that is, those tracks in which it is important to have great traction, and to generate grip mainly on the rear axle.

Compared to McLaren, in terms of set-up, the Ferrari did not present a car that was too light, on the contrary, the rear aerodynamic configuration chosen by Ferrari is practically identical to that used in Belgium and Azerbaijan.

Specifically, the rear wing of Monza featured a main plane with little wing angle, but with a movable flap with decent size. The only change with respect to Spa concerned the removal of the gurney flap, to reduce part of the drag.

An aerodynamic configuration like this allowed Ferrari to still be fast in the DRS zones. Other music obviously when it was necessary to defend oneself in the straights with the mobile flap closed.

The fact that we did not choose a set-up that was too light was to avoid penalizing too much the front axle which we know is and will remain the weak point of the SF21 at the end of the season. After the problems encountered in Belgium, a more conservative set-up was chosen to guarantee better tire management.

Due to a slightly heavier set-up, the SF21 showed excellent times in the central sector, where the two Lesmo curves are present. 

In terms of actual updates, a new front wing was used on the Ferrari.

The new wing specification features 'cut' flaps in the innermost part to balance the lower rear load while eliminating drag.

If it couldn't have been more than that at Monza, the bitterness of the occasions that vanished at Silverstone and above all in Monte Carlo remains in Ferrari's mouth. Ferrari has had its own chances of victory but has never managed to achieve anything concrete, unlike Alpine and McLaren.

In the fight for third place, with eight races remaining, the battle remains close. McLaren certainly took advantage of his own chance of victory, maximizing the result with a brace.

From now until the end of the season we should no longer see big changes on the cars and the values ​​on the field will be conditioned mainly by the adaptation that the cars will have in the various circuits. It will therefore be essential from now on not to waste opportunities, being ready if Mercedes and Red Bull should make any mistakes.

How Mercedes has (technically) overturned the World Championship in two Grand Prix.

There is a World Championship. Far from being taken for granted in this modern era of Formula 1. Hamilton versus Verstappen (195 to 187 points) and Mercedes against Red Bull (303 to 291 points). To the sound of reversals and changes of hierarchies. Beautiful!

After a start to the season that showed us Red Bull's superiority even though the first race went to Lewis Hamilton, thanks to a better understanding of the W12 and a few too many problems in making the updates brought to the track by Red Bull and the power unit work from Honda, the Mercedes car has returned to the level, if not ahead, of the RB16B between Portugal and especially Barcelona.

At Portimao, Red Bull brought a hefty aerodynamic update to the track that struggled to get to work properly.

However, in the following month of racing (or a little more), Red Bull managed to overturn the world championship, thanks to some aerodynamic updates brought to the track that also made it possible to fully exploit the potential of the Portimao package; not to be underestimated then, the recovery in terms of power thanks to the second Honda power unit introduced in the French Grand Prix.

More power and more reliability. Thanks also to the change of specification of one of the macro-components of the PU subject to quota, the turbocharger it's believed, approved by the FIA after the competitors, including Mercedes, had also given their approval.

Only with further updates between Monaco and Baku did the situation improve, with the RB16B taking off against the W12.

Steps forward that have allowed the Japanese engineers to compete on equal terms, and even slightly more, with the Mercedes PU.

Always focusing on Honda, after the Verstappen accident at Silverstone, there was a strong concern for the Power Unit.

After being sent to Japan, replacing some non-quota components, it had been checked at the counter with the "ok" for its use in the Hungarian Friday  Free Practice; in the event of a negative result on some component, plan B were already in place to use the first power unit with the replacement only in case of battery problems, the most 'worrying' element, and the control unit.

On the other hand, the Hungaroring track, although it has become more power-sensitive with the current cars than a few years ago, is not so stressful for the macro components of the power unit and above all the horsepower of difference between PU 1 and PU 2 would have much less impact than in Spa-Francorchamps or Monza, two of the next three circuits (Belgium, Holland, and Italy) on which it will race.

The good results obtained in Friday's Free Practice allowed Verstappen to keep the best performing second unit (that of Silverstone) in his RB16B.

However, after a disappointing qualifying (all Mercedes front row), a further cold shower arrived for the Dutchman: a 'worrying' crack was found on the engine. Keeping that ICE in the car for the race meant taking too much risk.

But so Plan B was blown. Blame parc ferme and the upgrade in terms of turbocharger specification. In fact, to avoid a penalty on the grid, it was necessary to mount elements of the same specifications used in qualifying.

Could Honda have just replaced the ICE, keeping the second turbocharger unit and MGU-H in the car? Surely. However, this choice is never made because the 'reserve' ICE engines arrive on the track already with the turbocharger and MGU-H motor-generator mounted and checked, this to allow a faster replacement and with fewer subsequent checks.

Updates in a key part of the car for Mercedes at Silverstone. The goal is to improve rear flows and consequently aerodynamic efficiency.

Moving on to Mercedes, after the Austrian double-header the mood was not the best. They knew they still had a few cartridges to fire, but they felt cornered as never happened in recent seasons; even more so than those fought against Ferrari. Red Bull seemed in full control of the world championship, both with Verstappen in the Drivers' and the team in the Constructors'.

But the Silverstone - Hungary brace has (again) changed the cards in this splendid world championship. 

"We have a number of things that will make our car faster in the next races. We hope that they prove to be enough," former Technical Director, James Allison from Austria, said.

They arrived in the next GP, at Silverstone, expanding a setup window that up until that Grand Prix was quite small. But the results had not yet been fully hoped for on the track. The first weekend of the Sprint Race is also in the way, with only one hour of free practice available before entering 'qualifying'.

For this reason, Mercedes considered what the novelty package showed as 'encouraging'. In Hungary, the missing potential was unlocked through better understanding.

Updates studied in the wind tunnel mainly between March and April, given that since May the world championship winning team has spent full time on the 2022 project.

But this was not the only novelty, as always anticipated by the English engineer: "We are also planning updates regarding the power unit, in terms of 'delivery'. The engineers are working to allow the power unit to express something more." 

In Hungary,  Mercedes brought an electronic upgrade to the track focusing on its power unit, as well noted by FUnoAnalisiTecnica in the onboard analysis. Nothing new from the hardware point of view but only a more 'unique' mapping that has allowed the world champion team to return to command on the engine side.

According to a competitor, this step forward was also possible due to a track that was not so stressful for the macro components of the drive unit. It will be interesting to see, and Spa-Francorchamps is already a good track for that if Mercedes is so aggressive on the 'unique mapping' even on more critical tracks for the engine; however, considering the allocation advantage Hamilton could have over Verstappen if the # 2 Honda power unit is inoperable.

According to the information, Formu1a.uno has collected, Mercedes could count on an advantage of 10 HP over Honda and 25 HP over Ferrari at the Hungaroring. 

The latter, as anticipated two months ago, will bring an update to its power unit on the track in the second half of the season which, according to what has been collected, should halve the current gap with Mercedes. This is the goal.

In conclusion, if the steps forward made by Mercedes on the engine side, we associate those made at Silverstone on the aerodynamic side plus the introduction of the new rear Pirelli tyres, one more variable and to be taken into account in such a sensitive F1, we can understand how this 2021 world championship is a real roller coaster. Not only of emotions but also of performance.

Formu1a.uno - Analysis: Mercedes W12, not lacking power but aerodynamic efficiency.

PHOTO CREDIT: Mercedes-AMG Petronas Motorsport

It has become a Verstappen show in this 2021 FIA F1 World Championship. At the 2020 'copy-paste' season we never really believed it because of the regulatory changes, once analyzed in detail, were much more important and radical than initially expected.

Being then tied to the 2020 cars, it is clear that those who carried a car with some endemic defects such as Ferrari, could not expect to fight to win the world championship this year; however, there was also the risk that those starting from a very competitive car could lose performance due to a bad adaptation to the regulatory changes. So it was, in the case of Mercedes and Racing Point, now Aston Martin.

In the case of Mercedes, that perfect combination of aerodynamics and mechanics found with the W11 has been broken also thanks to a forward movement of the engine and the pressure center. With further advancement of the latter (the greater aerodynamic load value generated by the single-seater), due to the 2021 regulatory changes, the rear has remained 'decompensated': the W12 thus works in a very small operating window. The setup changes have become rather limited to avoid problems on one or the other axle.

After a third of the world championship, we find ourselves with Verstappen and Red Bull at the top of the world championship. In the last five Grand Prix, the Dutchman recovered an impressive 46 points over Lewis Hamilton, 73 even Red Bull in a Mercedes.

The seven-time world champion entered the second Austrian weekend with good impressions. Unlike the RB16B, the W12 of the Austrian GP was in the same specification as the previous weekend and the improvements could only be found through an optimization of the setup.

Last week Hamilton spent many hours in the Brackley simulator finding 'promising' setups, but which once brought to the track did not give the desired results. For this reason, from FP2, the W12 of Hamilton took a step backward, using the 'basic' set-up of the previous weekend (Styrian GP) that Valtteri Bottas had used in the first hour of practice.

The low temperatures on Friday helped Mercedes get closer to Max Verstappen's RB16B but when the tarmac exceeded 50°C, both W12s failed to extract the maximum from the C5 compound, also paying duty from Lando Norris’ McLaren. They weren't expecting it at Mercedes.

Max Verstappen instead took to the track with a further updated RB16B: new front wing specification, the third in five races, new bargeboards, and the confirmation of the shark tooth diffuser, also available to Sergio Perez this weekend.

The Dutchman, together with his staff of technicians, opted for a slightly heavier set-up than the one used the previous week to get the C5 compound working at its best in qualifying.

This allowed the W12 to halve the gap on the straight (just over a tenth), however, the same gap opened up in the corners, thanks to not full exploitation of the C5 compound by Lewis Hamilton's W12. Also interesting is the comparison with the equal an equally powered MCL35M (Mercedes power unit): Hamilton lost almost 5 tenths to Lando Norris on the straight, recovering a couple of them in the corners, with an excellent W12 also in place against Red Bull.

There is no doubt that the car of the world championship team is the one, together with Aston Martin, to have suffered the most from the regulatory changes. In addition to no longer having that perfect combination of aerodynamics and mechanics found with the W11, its important aerodynamic efficiency has also been canceled.

An engineer from a competing team told Formu1a.uno that Mercedes has taken a two-year step back from that point of view, returning to the values ​​of the much 'resistant' (to progress) W10.

We tried to verify this with the imagery available, comparing the rear wings used in the last three seasons in Austria by Mercedes, given that that macro aerodynamic component is one of the heaviest in terms of drag.

Differences in rear wings between the Mercedes of the last three seasons.
PHOTO COMPARISON: Formu1a.uno

The result is a very charged Mercedes at the rear compared to last season. This penalizes the W12 in the straights not only in comparison with Red Bull but also and above all with the McLaren-powered peer.

It is therefore not a question of engine and horsepower as Hamilton would like to believe. An advantage that until the French Grand was in favor of Mercedes, due to the problems manifested by the Japanese PU (Honda) in Bahrain, now solved thanks to the second Honda power unit brought to the Paul Ricard track. According to what has been gathered, the PUs are now very close both in qualifying and in race conditions with a gap quantified by the competitors in the order of 5 HP. According to Ferrari, the advantage is with Mercedes, however, according to Renault, the advantage is with Honda. But little changes given in the very small gap.

Rear aerodynamic downforce further lost by Lewis Hamilton during the Austrian GP: for over half the race there were no less than 30 points missing (the teams measure the aerodynamic load in points), which in Austria are equivalent to 6 tenths per lap initially, to climb then gradually the tyres wear out prematurely. This problem destroyed the aerodynamic balance of his W12, which started to slip and put too much stress on the rear tyres.

The Low Rake setup used by Mercedes and Aston Martin were penalized more by the 2021 regulatory changes.

"I think it was around lap 30, at the exit of turn 10 [the last corner]," Toto Wolff said. "There is a rather aggressive curb there. We saw that it was not a driving error but a problem with the component that failed ”.

So Hamilton was not only slower, but he also had more tyre wear; this forced Mercedes to make a second pit stop where the mechanics, in addition to the tyre change, also removed 1 degree of front wing to balance the car as the pressure center had moved 'too far forward'.

However, even without this major problem, Verstappen's Red Bull was unstoppable for the seven-time world champion. “I think we would have been satisfied with a second and third place, which was realistically the best we could have gotten; Max's pace was in fact too strong for us." Shovlin said.

The Mercedes W12, as already labeled last week, as a car that is now at the end of its development in its performance and understanding. "We haven't been particularly strong here in general," said the British engineer. “It doesn't show that much towards Red Bull, but from how we were put under pressure by McLaren in the second round. We have not made any real progress here in either race ”.

This is why the upgrade package for Silverstone is highly anticipated as it should help unlock further potential, directly and indirectly, from a car at its peak of understanding and performance. Will it be enough? "We have some new updates for Silverstone, but I don't think they will help us bridge the gap," said a grim Lewis Hamilton in the post-Austria interviews.

At Mercedes, however, they do not give up on defeat, hoping that even the characteristics of the latest tracks on which they raced have shifted the balance of power in the world championships. This is why Silverstone, which has always been a great Mercedes stronghold, does not become an exam only for Ferrari but also and above all for the world champions.

Formu1a.uno - Analysis: this is how Red Bull turned the World Championship upside down.

PHOTO CREDIT: Red Bull Content Pool

May 9, 2021: Spanish GP was the last Mercedes win with Lewis Hamilton. From then on, four consecutive victories for Red Bull: Monaco, Baku, Paul Ricard, and Austria 1.

The latter is “the most dominant of the year”, according to Red Bull Team Principal Christian Horner. Verstappen's advantage in the drivers' championship does not say everything because it is true but up to a certain point: in fact, it could have been higher. The Dutchman could have won in Bahrain and very calmly finished ahead in Baku.

Lewis apparently seems to be extracting maximum performance from what he has. A little. And while it is a merit, at the same time it is worrying because it doesn't seem enough. 

The Red Bull Ring is always an important benchmark. On a track like this, with three DRS zones, if you can keep your competitor out of these, it means you have more. And the RB16B actually had more all weekend. When Hamilton came into the pits for his second stop, which is useful to take the fastest lap and the extra point, his delay was nearly 18 seconds, a gap/space of two and a half tenths per lap. Real.

In just over a month, Red Bull overturned the world championships, with what is to be considered in all respects a decisive 'world' acceleration.

How? Thanks to some aerodynamic updates brought to the track in the last GPs, which also made it possible to fully exploit the potential of the Portimao package, and to the recovery in terms of power, thanks to the PU number 2 introduced in the French GP by Honda.  

But let's take a step back, analyzing how Spielberg's domination came about for a world championship that is to be divided so far into two parts. The first, of continuous growth for the Mercedes team coupled with too many difficulties for Red Bull. The second, after the Spanish GP, with the decisive increase in performance (especially in the race) of the RB16B associated with a W12 instead of more 'development'.

We started in Bahrain with the belief that Red Bull could finally oust Mercedes from the role of the undisputed queen of F1, dictated by dominated pre-season tests. At least partially, so it was, even if the victory of the Grand Prix went to Lewis Hamilton.

However, in Sahkir some critical issues had emerged with the Honda power unit, which we had already talked about. Vibration problems had in fact resulted in the replacement of some electronic components (battery and control unit) on the cars of Perez, Gasly, and Tsunoda as well as requiring a less aggressive use of the hybrid part of the Japanese unit, which caused the RB16B to lose performance.

This, coupled with the small leap forward made by Mercedes with its power unit at Imola, had opened a slight gap in engine performance between the German power unit and Honda. Well compensated in qualifying by better use of the tyres by the Anglo-Austrian car, unlike the W12.

Thanks to a more efficient diffuser, Red Bull are able to use the spoon wing already brought to the track in Baku (V2) at the Paul Ricard.

In Portimao, Red Bull arrives with an important package of updates, which sees the implementation of new flow diverters and adjustments to the bottom and to the diffuser; the desired results are not seen. The same goes for the following weekend, in Barcelona.

The performance of the W12, on the other hand,  continues to grow so much that in the Spanish GP we witness what was to be considered as a real performance overtaking.

The steps of the world champion team went through an intrinsic improvement of the car. An attempt was made to better understand the car and to find that correct balance between the front and rear axles, undermined by the 2021 regulatory innovations and, not least, by the abolition of the DAS which allowed the W11 to quickly have the front wheels up to temperature.

While Red Bull, more in place right from the start, was trying to get performance through updates that were not giving the expected performance improvements on the track.

In Spain, Red Bull Racing enters with a high-downforce rear wing to protect the rear tyres. However, the lack of horsepower of the Honda power unit does not allow him to keep it for qualifying and race. Too much time lost on the forehand against the W12s due to an underperforming PU compared to the Mercedes one and a high-rake set-up that intrinsically increases the aerodynamic resistance of the car.

From the FP3s, the engineers, therefore, decided to use a lighter, spoon-shaped wing on both RB16Bs, however, causing a crisis in the management of temperatures on the rear axle. Mercedes dominates.

Between Monte Carlo and Baku, Red Bull has worked hard on updating its front wing. In the illustration, the specification at the beginning of the year (Old Spec) was compared with the one brought to the track in Azerbaijan (New Spec).

However, in the following GPs, the turning point arrives: two updates to the front wings, brought between Monaco and Baku, coupled with a novelty to the diffuser (only partial in Monaco, complete only in Styria), allow Red Bull to find a lot of 'efficient' downforce at the rear, opening that window of operation and setup that was the real weakness of the RB16B compared to the W12.

The novelties to the diffuser brought to the track by Red Bull between Monte Carlo and the Styrian GP concern the outter profile. First only partially, then along the entire length, having a sawtooth profile, according to the engineers of the Anglo-Austrian team, allows increasing the efficiency of use of the rake set-up.

News used immediately by Max Verstappen while Checo Perez is granted only in subsequent GPs if evaluated positively in terms of costs/benefits since the budget cap issue is anything but simple to manage.

Thus, while Mercedes is forced to use the rears more, adding drag to the W12, Red Bull manages to enter the French GP weekend with a rather minimal spoon wing, finding an optimal 'balance' for minimizing tyre problems on a very complicated track, especially on race day.

Over the weekend were Honda, thanks to the introduction of its second power unit, solved those annoying problems that had limited its performance for 5 Grand Prix.

From the GPS data, the engine performance of the RB16B returned to that of Bahrain, slightly ahead of Mercedes. Ferrari followed, with Renault closing the engine performance ranking to date. All grouped in 25 horsepower, no more, according to what was collected.

The (small) advantage of PU alone does not justify the important advantage in the straights of the RB16B. In between there is also the greater aerodynamic efficiency, which allows Red Bull to be able to use much less 'draggy' rear wings.

Returning to the horsepower increase of Honda power unit 2, according to Red Bull the step forward is to be found in the new oil specification that ExxonMobil has brought to the track: “We have new oil, so I think Exxon should take all the credit for the steps forward Lewis indicated. From the point of view of the engines, they are homologated, and the second unit is the same specification as the first ”.

We remind you that engineers are allowed to make changes to their power units to solve reliability problems.

All this while Mercedes is reaching its 'maximum' understanding of the W12, a car that has now been praised in terms of performance.

Lewis Hamilton understood this too. Hence his important outburst in the post-Styrian Grand Prix: "Red Bull continues to make improvements and it is clear that it has made many in recent races. It is currently impossible for us to keep up with them. Even in the long runs, they are better. They continue to make fast laps one after the other and on the straight, we lose a lot." claimed the seven-time world champion.

The Low Rake set-up used by Mercedes and Aston Martin was penalized the most by the 2021 regulatory changes.

He then continued, getting to the point: "We need updates of some kind, I don't know where, rear wing, engine or any other component, but we certainly have to make up for the ground we have lost".

An appeal to the 'wind' as Mercedes are already fully oriented towards 2022 and no major update is expected in the next Grand Prix, but only minor aerodynamic updates and in terms of exploitation of the power unit.

We await a few more GPs, but the road seems to be drawn. Tyres permitting.
