(Michelin pilot sport 4 suv)
Why is the cover image of this article a formula 4 and the headline of the article is a tire..... Don't rush to hammer me, in fact, I am not selling dog meat with sheep's head, because all the models of this event are equipped with Michelin ps4 series tires (the sponsor dad is Michelin).
If you're interested in the Michelin PS4, you should know that it's a tire that combines performance with comfort, a twin-tread formulation design, dry wet grip and braking performance. It is a street tire that is not too expensive (less than 1000) and can greatly improve the performance of the vehicle, and the ats-l of our editorial department Zhihao and the 316i of Liudi have replaced this tire.
In the past, the ps4 tire was still considered to be the "exclusive" of the car, and now the SUV special edition has also come, those drivers who drive the SUV but love to control, change the tire! PS: At present, Michelin has signed contracts with luxury brands such as Mercedes-Benz (glc), BMW (x3), Volvo (xc40), etc., and the above models will be originally matched with PS4.
Well, the previous advertising time is over. Before the test drive experience begins, we remember these data: "185 horsepower", "470kg weight", "full carbon fiber body", "1:1 without power steering", "sequential transmission".
The combination of the above series of famous words becomes a formula 4 car. F4 is a popular Formula race between kart and f3, filling the gap between kart and f3, and is designed for young drivers to build a promotion path from go-kart to f4 to f3 and finally to f1. That said, this may be the vehicle closest to f1 that the average person can access at the moment.
And this formula 4 car, still equipped with Michelin tires, but not ps4, but Michelin racing slick tires, commonly known as bald tires. This bald hot melt tire has almost no grip before preheating, and can work up to 100 °C after preheating.
Formula 4 racing cars, like the manual transmission model, actually have three pedals, from left to right, clutch, brake, and accelerator. However, the clutch only works in the starting and initial stages, and when the vehicle is started, the whole process relies on the paddle shifters to shift gears. Formula 4 starts with a clutch, then ignition, left and right paddles pulled back at the same time to lift the safety device, followed by two seconds to dial the gear levers to hang into a gear.
When all the previous steps are completed, you need to cooperate with oil separation, but unlike ordinary family cars, you need to at least blast the throttle to reach the amplitude of about 4000 revolutions to slowly release the clutch, if you do not use this similar ejection method to start, you are easy to turn off.
When you successfully start, you can fully step on the throttle to pull up gears, at this time formula 4 is exactly the same as a civilian car with a paddle shifter, but the frustration of shifting gears will be much stronger, and the high-speed roar of the engine is deafening.
Driving the formula 4 out of the p-room into the track, the first thing I sensed was not how fast the car was, but how heavy the steering was. Due to the lack of steering power, even a 13-inch bald tire is enough for you to twist the steering wheel as hard as you would lift a dumbbell. But fortunately, the steering is a "1:1" ratio, so when the vehicle is driving, you only need to move a little, and the tires have already begun to react, which is the real "precision steering". The highest state of the so-called "where to fight" is no more than that.
"185 horsepower" if put on a civilian car, may be just a small pediatric. But when this "185 horsepower" is placed on the weight of the "479kg", it is another matter. There is a saying in the automobile modification industry called "prefer to lighten one pound, do not increase ten horses", which can be seen how important lightweight is to the improvement of performance. So drive the formula 4 inside the track and you'll find that at 100km/h, speeding up is almost in the blink of an eye. The huge thrust-to-weight ratio makes Formula 4 look like an off-string arrow, and this arrow is still a rocket. And this rocket-like speed, supported by racing brakes, basically brakes and stops, and thermal decay doesn't occur at all in the few laps I experienced.
If you don't have a reference next to you, when you accelerate fast enough, you will even have a sense of stillness of the objects around you. As the first text d says, "Lately he's been looking slower and slower", it's actually because he's driving faster and faster.
So for safety, each formula 4 has a Porsche 718 pilot in front of it. Formula 4 can run as much as you want, but only if you can't go beyond the 718 in front of you. So I couldn't experience the limits of formula 4.
That being said, during the race, the Pilot 718 will also constantly test the skills of the rear driver. The closer you drive to the 718, the faster the 718 will drive, and formula 4 is like a puppy, constantly running faster and faster with the 718 in front of you. In this case, the gap between civilian cars and racing cars comes out. Because I had been forcing the 718 to drive faster, the 718 in front of me also realized that I was not here to swim in the river, so I also began to run with all my strength.
However, in many high-speed bends, the 718 has begun to appear obvious tires, and when the body posture of the body is unstable during the sharp braking, I think the vehicle is still as stable as Tarzan when driving formula 4. I even feel that in some high-speed corners, if I use a lower speed, there is no help from downforce, but I can't get by. So sometimes watching f1 racing, don't think that others are driving so fast to cross the corner is playing for their lives, to some extent they drive so fast is actually saving their lives.....
As I drove faster and faster, I had already discovered that the limit of formula 4 might not have arrived, and my own limit had arrived first. After only two laps, my unicorn arm was already a bit overwhelmed by maintaining a "1:1" turn. Coupled with the lateral g-value generated by the continuous high-speed cornering, I swung left and right, and my body was a little uncomfortable. I was going to take the last lap to see if I could push the car to the limit. The pilot car 718, which I have been driving, turned on the double flash, announcing that now that the game is over, I will follow back to the p room.
When I got off the formula 4, my first thought was "How physical and mental are the F1 racers?!" ”
After getting down from the f4 car, exhausted, and then let me drive a civilian car, in fact, I couldn't turn around for a while. Because even though the speed is not very fast, the driving feeling of the f4 is too strong. Like "1:1 steering" and "horizontal large g-value", these are primitive driving pleasures, and it is easy to make people who love driving feel good.
So driving these civilian performance cars, even if it is a Porsche 718 or 911, I will have a feeling of being bored. After all, the f4 car just now has allowed me to say "I'm all right, what about you guys?" ”
And good people are generally very tough, so driving 911 these "low-end cars", relatively easy. But racing cars and civilian cars are two dimensions, and many things are different. First, the driving methods are different, and the second is the different levels of technical reserves. But without exception, they will all change the driving quality of the whole vehicle due to the change of tires.
Unlike racing cars that pursue extreme speed, civilian performance cars must also consider affinity while pursuing speed. Therefore, if you want to perfectly control the civilian performance car, you should consider the patience of the driver more than the perseverance. Like this kind of slippery road surface that simulates ice, if you want to use non-snow tires to achieve drift, you need to grasp the communication between tires and road surfaces with extreme delicacy, the throttle is large and slippery, and the throttle is small and cannot be floated.
Although the vehicle has been equipped with a Michelin PS4 with good grip, you can feel that the tires have struggled to find grip on the "ice surface", but the driver who is helplessly thinking about drifting always kicks the balance off the throttle. In many cases, drift does not become anti-spin, you can only love the magic circle.
If the car equipped with ps4 returns to the normal road and does emergency line changes, acceleration brakes and other projects, it will be different. The grip of the Michelin PS4 is a real response to the actual driving, coupled with a flexible Porsche 911, the combination of people and cars is no more than that. There is only one way for a civilian car to get the highest lift at the lowest cost - to change the tire.
Netizens who pay attention to our performance test can find that if the same car uses different tires, there are certain differences in accelerated braking, pile winding, line change, fuel consumption, noise and other items. This is why we often suggest that to improve sound insulation and improve vehicle performance, tire change is the simplest and most rude way.
As the saying goes, "a good horse is paired with a good saddle", and a good car should also be paired with good shoes. A performance car with a good foundation must be matched with a set of tires with excellent performance. Even an excellent car company like Porsche is inseparable from cooperation with tire manufacturers.
The Porsche 911 is indeed a perfectly tuned and easy to drive precision, and the ps4 with good grip is like a finely crafted rein, with the help of which you can better control this "horse" 911.
After all, no matter how good your bottom is, it is impossible not to wear shoes? "Barefoot can't run but wear shoes" is such a truth. However, for the matter of tire replacement, it can not be too impulsive, or specific problems are analyzed, and the most suitable tires for their cars can be selected according to the model positioning to achieve the best results.
After all, if you like to play basketball, go buy aj; if you insist on wearing vans, are you afraid that you are going to hurt yourself?
Some people say that car racing is a polluting and meaningless activity. That's because they don't look at the contribution behind the car – many of the technologies on civilian cars: such as abs, turbocharging, four-wheel drive, ventilated disc brakes, aerodynamic design, etc. are all explored by the car and then sent down to the civilian car step by step.
The marketing profits of civilian vehicles can be invested in the research and development of racing cars, and the technical experience accumulated by racing cars can be mass-produced on civilian vehicles. Civilian cars feed racing cars, and racing cars feed back civilian cars, which is a virtuous circle. Perhaps the impact of racing on everyday life may be invisible, but you can't deny that it does exist, and the biggest beneficiary of racing will always be civilian cars.
Civilian carsborn for driving, racing carsborn for racing.
