It rained heavily, and deep water accumulated in the depressions on the road. A colleague at work said that there were at least a dozen cars parked at the intersection next to the workplace.
what Mercedes-Benz , BMW , Audi , small sports car have all failed here. However, some economical family cars can pass without hindrance.
Of course, economical cars cannot compare with those luxury cars in terms of performance, but there is one problem that cannot be ignored.
refers to the height of the car chassis, because the chassis of most luxury cars is much lower than that of family economy cars.
Because the car chassis is low, the drag coefficient is low.
The low chassis makes it easier to reflect the streamlined shape of the car, making it more aesthetically pleasing and luxurious.
The wind resistance coefficient is low, which can achieve the purpose of saving fuel. Reducing the drag coefficient places high demands on the overall design of the car. Therefore, the reserve of factory technology and the reserve of high-end talents are the key to determining the performance of the car.
The lower the chassis of a luxury car, the lower the exhaust pipe, and the shallower the wading depth. In this regard, family economy cars have advantages.
This is a problem with the car itself. The key is still a human problem.
luxury cars all have automatic transmissions or manual transmissions. When a car wades into water, the resistance of the water will cause the car to have an obvious sense of lag. The rising water will flood the front hood and exhaust pipe. You cannot release the accelerator at this time, because the exhaust gas will prevent rainwater from entering the exhaust pipe. Once the rainwater enters the exhaust pipe, it will enter the body and cause the car to stall.
Economic cars generally have high chassis and high exhaust pipes, so in the same deep water, economic cars will have more advantages.
In fact, whether it is a luxury car or an economy car, as long as the rainwater overflows the chassis, there is a certain degree of danger.
If you encounter deep water on the road, it is best not to take risks.
If you have no choice but to pass, you must pay attention to a few points.
First of all, you must keep a large enough distance from the car in front to prevent the car in front of you from suddenly lying down, causing a rear-end collision and causing a traffic accident.
If it is an automatic transmission model or an manual-automatic model, it is best to upgrade the automatic transmission to the S gear (that is, the sports gear mode). Automated transmission models should be shifted into manual transmission mode and drive forward in first gear. Don't change gears while driving, don't let go of the accelerator, control the direction well, don't be afraid because the car has obvious lag, keep your foot on the accelerator, keep applying the accelerator, and push the accelerator to the bottom when necessary, and don't delay.
If the car has an automatic start-stop function, turn it off to prevent it from automatically igniting after a sudden shutdown.
The same is true for manual transmission models. Put the accelerator in first gear and continue to apply the accelerator without releasing the accelerator. If necessary, increase the accelerator to the maximum.
After all wading cars stall in the water, be sure not to spark it again, because the wading car is only insured for one spark. If it sparks twice,
or multiple times, the insurance company may not cover it. .
There is too much rain in summer. Friends should pay more attention to the weather forecast. If it rains heavily, try not to go out. If you go out, you should pay attention to safety or choose other ways to travel.
