After the Fédération Internationale de l'Automobile (FIA) announced compliance with the double-layer diffuser, teams reacted quickly. Pen, fun, pavilion www. biquge。 The fastest responders were McLaren and Renault, who used the double-layer diffuser directly in this race. Scuderia Ferrari announced a more exact date, and several other teams also said that their own double-layer diffusers were under development, and even Red Bull Racing's legendary design master Nuvey also expressed his submission and was ready to install a double-layer diffuser on the Red Bull car.

As it stands, Ferrari has said it will use a double-layer diffuser for the next race, BMW Sauber Racing has tentatively used a double-layer diffuser for Spain, Red Bull Racing expects Monaco to come up with its own double-layer diffuser, and Toro Rosso will be slightly stricter than Toro 1.

The various teams have expressed their positions, but the Indian Force is indifferent, and the Indian Force team has not released any information about the double-layer diffuser, which has caused many media people to have various speculations. And the most reliable guess is that India's power has no money, so it can't develop a double-layer diffuser for a while.

The media didn't know that the Indian forces had been pitted by other convoys.

Due to aerodynamics, any bit of alteration to the diffuser is mounted at the rear of the car's chassis, so the biggest impact of the diffuser change is the chassis and suspension. Not every car's chassis and suspension are suitable for diffuser modifications, and some cars have chassis suitable for diffuser modifications, so they will have much less work; And if the chassis of the car is not suitable for modifying the diffuser, then the team engineer has almost the equivalent of redesigning a race car.

The double-layer diffuser was planned by Ross Brown for a long time, and it will take a while for other teams to re-develop it, and even for giants like Ferrari and McLaren, who are super research-capable, all they can come up with now is a transitional double-layer diffuser, and this is the result of more than a month of research.

The Force India team did not plan to study the double-layer diffuser from the beginning, and Omi thought that the other teams were supporting him, so he was keen to go to the FIA lawsuit, but now the lawsuit has been lost, and the Force India team has become cannon fodder.

In terms of double-layer diffusers, the start of the Indian Power team is already playful, and their research and development capabilities are not as good as the big teams, which is equivalent to a race, and the slowest person who starts is much later than others, and the final result can be imagined. What's more, for the sake of his own face, Omi didn't want to study the double-layer diffuser at all, and the fate of the Indian Power team this season was also doomed......

The Shanghai International Circuit is a very troublesome track, and it can even be said to be the most troublesome track.

As a track that has only been built in recent years, the hardware facilities of the Shanghai Circuit are first-class, but the design of this track is a big challenge for the drivers and the team's engineers.

Each track has different characteristics, such as the Monza circuit in Italy, the Monte Carlo circuit in Monaco with its most famous slow corners and tunnels, the Circuit de Spa-Francorchamps in Belgium is the steepest track, the Circuit de Catalunya in Spain has the title of perfection, and the changeable weather and rain battles at the Sepang circuit in Malaysia, to name a few.

Cars race on different tracks, which require different tuning, for example, Monza uses relatively low downforce, while Monte Carlo is the opposite; The Sepang circuit takes into account the occasional rain, while the slope of the spa circuit requires precise adjustments to the suspension of the cars.

Only the Shanghai track has almost all the above characteristics!

The two large straights at the Shanghai Circuit are typical high-speed track configurations, and the cars can reach speeds of up to 330 kilometers per hour at the end of the straights; The successive hairpin turns of Turns 2 and 3, as well as Turns 6 and 14, are low-speed corners and require 2nd gear to pass, which is again equipped with low-speed tracks; Turns 7 to 10, as well as Turns 12 and 13, are high-speed corners, which conflict with the low-speed corners ahead; Another point is that the track has a lot of gradients, with uphill and downhill corners, and the driver has to carefully control the angle of the slope in and out of the corner.

Some drivers will like this kind of track very much, they find it very challenging, while some drivers will not like this kind of track very much, because the fast and slow times combined with the downhill slope have a great impact on the rhythm of the drivers, and some drivers will lose their sense of rhythm here, they feel that the track is difficult and tiring.

Some riders love and some hate, but in the eyes of the team engineers, there is only one word to describe this track, and that is "trouble"!

Other tracks, high-speed tracks with high-speed tuning, low-speed tracks to low-speed racing car tuning, various configurations of the car, such as the height of the suspension, downforce adjustment, etc., can also have a relatively unified tuning method, only the Chinese track, there are high-speed, low-speed, steep slopes, at this time it will test the comprehensive performance of the car. The team's engineers needed to find the right balance to be able to perform at their best on all sections of the road without being behind the cars on other sections.

On this track, the double-layer diffuser still has an advantage, but not as much as the other tracks, and whether it is suitable for high-speed tracks or corners, there is a place for it here. Cars that rely more on aerodynamics, for example, perform better here.

"It's a troublesome track, and it's on my home turf." Zhang Guan sighed a little helplessly, he had just gone out for two laps, and he had already felt the difficulty of this track.

It's Friday practice, but the stands around it are already full of spectators, and the tickets for Friday practice are the cheapest in comparison, and for some residents in the surrounding urban areas, it is also good to come and see the practice because they can't buy tickets for the main game.

McLaren Racing fitted the transitional version of the two-layer diffuser and had a strong Friday morning, with both cars finishing first and fourth respectively. On Friday afternoon, Zhang Guan gradually adapted to the running style of this track, and finally won the first place in practice.

After 90 minutes of practice in the afternoon, Zhang Guan returned to his accommodation after dealing with the swarm of reporters and enthusiastic fans.

"How does it feel? Are you still adapting? Barrichello asked.

"This track is really tiring to run, especially the corners with ramps, you have to carefully control the direction, and after more than 50 laps, it is a test of concentration." Zhang Guan replied.

"And that's not all!" Ross Brown stared at a document in his hand, and continued: "This is the information that the weather service team just transmitted, and there are satellite cloud images, I'm afraid it will rain during the race the day after tomorrow!" ”

"Another rain war? High-speed tracks, low-speed corners, slopes, and now even God is here to join in the fun! Zhang Guan smiled bitterly: "Is this still my home field?" (To be continued.) )
