All five red lights went out and the Malaysian Grand Prix officially started.
Zhang Guan didn't make any mistakes in his departure. He successfully defended his first position and entered Turn 1.
Turn 1 in Malaysia is a hairpin turn, as long as the route is taken, it is difficult to overtake at turn 1. But immediately after turn 1, it was turn 2. Turn 2 is a reverse turn, which is a good overtaking point on this track. If the route becomes larger when turning out of turn 1, it is easy to be overtaken by the opponents who occupy favorable terrain in turn 2. The short straight after turn 2 will allow the transcendental to stabilize his advantage.
The fourth behind Rosberg started very well. He surpassed two Toyotas and came to Zhang Guan's side, and wanted to grab the inside line of Turn 2 to surpass Zhang Guan, but Zhang Guan's exit speed was faster than Rose Borg is faster, even if Rosberg grabbed the line, but lost the speed of the corner, Zhang Guan took the lead to run out of the second corner and used the short straight ahead to secure his first place.
In the back of the car, Barrichello, Raikkonen and Alonso started very well. They all caught up to different degrees. The third Toyota team, Glock, started poorly and was squeezed into the first place. Six locations.
After the start, the first corner is often bloody, not to mention the Sepang track is still a continuous play, but fortunately the Sepang track is wide enough, so no vehicle has an accident on the first lap.
Some sections of the track are dry, while others are slightly slippery, which is the last thing drivers want to encounter. Old drivers know that heavy rain is not terrible. The most terrible thing is that when the light rain started, the road was semi-dry, and the drive was particularly easy to slip. Now it is the same on the track.
There is no shortage of bad luck in Formula One cars. Today’s first bad luck was born on the first lap. McLaren’s Kovalainen suffered a side slip on a slippery corner and directly rushed into the buffer zone. As a result, he became the first driver to retire. And they retired for two consecutive matches, which is a rainy day for McLaren who is troubled.
As the race progressed slowly, the distance between the cars also opened, the advantages brought by the double diffuser gradually manifested, Zhang Guan steadily occupied the first, and the gap with the second place is getting bigger and bigger, And Barrichello also surpassed the connection of world champion Alonso and came to the fourth position.
On the fourteenth lap, Red Bull Racing Vettel led the advanced station, which opened the prelude to the drivers' first pit stop. Then Rosberg, second, also chose to pit and refuel, followed by two Toyota drivers.
As for Zhang Guan, the amount of fuel added is more, and the degree of tire wear is expected to be much lighter before the game, so Zhang Guan can hold a few laps, he began to use the advantage of lighter oil, brushed up the fastest lap .
The high-temperature Sepang track has always worn tires, but the rain this morning made the track temperature only 36 degrees Celsius, which made the tire granules much less. Even soft tires can stick to three times more than usual. Four laps.
The dark clouds in the sky are getting thicker and thicker, and the fans in the open-air auditorium have pulled out their umbrellas and are ready to deal with heavy rain. The narrator kept mentioning the rain, but there was no drop of rain so far.
"The weather forecast before the game said that it will start to rain half an hour after the game, and now it's half an hour, but the rain hasn't rained yet!"
"I think it should be fast. Look at the sky. It looks like this. There will be ghosts if it doesn't rain!"
"Look, look, Ferrari's Raikkonen is coming in. He changed the rain tires!"
On the eighteenth lap, Ferrari driver Räikkönen pitted into the station, and he changed into a set of full-tires.
"It hasn't rained yet. Why did Ferrari change to a rain tire?"
"Does Ferrari already know that the heavy rain is coming soon?"
"Perhaps Ferrari is simply betting that they are changing to full-tires instead of half-tires, which is obviously betting on the coming of a heavy rain!"
The only difference between a full rain tire and a half rain tire is the grain on the tire. There are more lines on the full rain tire, the tire drainage ability is stronger, and the car is less likely to slip. Of course, the resulting friction is increased and the downforce is reduced, which will seriously affect the speed of the car.
Under normal circumstances, there is water on the track or there is not much rain. The driver will choose a semi-rain tire. Only when the road surface is very exposed and the rain is very heavy, the driver will choose the full rain tire. Nowadays Ferrari chooses all-rain tires, obviously it is like telling everyone that there will be a heavy rain.
Ferrari's change to a full-rain tire also surprised many teams, especially the few teams that just entered the station to change their tires. It’s important to know that this year’s Formula 1 dry land tires are all bald tires, that is, tires with no grain on the surface. With this tire, running the rain and fighting with a little rain, you can stick to it a little bit, but if it’s really raining, The bald tires must be slippery, and they will have to enter the station again to change to the rain tires, which is equivalent to entering the station one more time, wasting more time.
Ross Brown picked up the intercom: "Zhang Guan, you have a very good pit stop window on the next lap. But what I want to tell you is that Ferrari changed to a full rain tire when he pitted just now!"
"It's not raining yet, why is Ferrari eager to change the rain tire?" Zhang Guan asked.
"Ferrari is different from other teams. They rented meteorological satellites and hired special climate analysts. They should predict that it will rain soon! They are now changing to rain tires. If it rains immediately, they can use The time for someone to get in and change the rain tires is beyond the front." Ross Brown said.
"But it has not rained yet. Rain tires will lose a lot of speed." Zhang Guan said.
"Indeed, the road is still very dry. Compared with the soft tire, a lap is more than a second apart. If there is no rain within four to five laps, Ferrari will lose its strategy." Ross Brown said.
"Do you have any good suggestions? What tires do we change?" Zhang Guan asked.
"My suggestion is that you insist on two more laps." Rose Brown continued: "You can slow down the car properly and protect the tires. We have already checked the latest weather forecast.
Ross Brown's voice had just fallen. A drop of water suddenly appeared in the position of Zhang Guan's helmet eyepiece. The water drop quickly disappeared on the goggles with the speed of the car.
"I probably don't have to insist on two laps." Zhang Guan continued: "It's raining now!" (~^~)
