Coquettish Rebirth

After asking Mr. Guo Konghui to find out, Jia Hongjian realized that the arc-shaped thing on the roof of the big truck was really a spoiler!It is really used to reduce the vacuum area behind the front of the car-wait, behind the front of the car?That's right, behind the front of the car!When the container is hung on the back of this kind of large truck, there is an obvious gap between the front of the truck and the container behind, and the gap is not small!If the spoiler is not installed, the airflow will sink directly after passing through the top of the front of the car, and then form a vacuum area behind the front of the car, which will greatly increase the resistance. At the same time, because there are containers behind, the airflow will hit The vertical surface at the front of the upper container causes the wind resistance to rise again!

Therefore, such a spoiler on the top of the big truck is actually used to raise the roof, so that the airflow can be further improved, and then when the airflow drops, it can just land on the top of the container, so that It is equivalent to minimizing the vacuum area behind the front of the car!Even similar to the spoiler on the top of the head, there are slightly bulging spoilers behind the doors on both sides of the front of the big truck. The role of the spoiler is to further squeeze the air so that the airflow can bypass the back of the front. The empty space of the car falls directly on the container behind.It can be said that the effect of having three spoilers on a large truck is obvious. The purpose is to integrate the front of the truck and the container behind it at the level of airflow, thereby reducing wind resistance and fuel consumption!

So in fact this spoiler is useful, but the role is not what Jia Hongjian thought, and it can't be used by Jia Hongjian!The practice of other people's trucks is actually not the same as our situation. In fact, they just made more "roofs"!So what about our suv?If our car was powered by another type, then Jia Hongjian would definitely not care about wind resistance.After all, the SUVs of other companies are also such a virtue, even Jeep’s SUVs have a lot of square fronts that look like bricks, and the wind resistance is even greater. Isn’t it loved by people?But the problem is.Our suv is the first all-electric and pure electric new energy suv!We are redefining a product!Such a product of ours is to have the advantage of flashing and blinding eyes compared with traditional gasoline engine and diesel engine suvs!

In Jia Hongjian's conception, what should be the highlight?It should be fast, it should have a large space, it should have a domineering sci-fi appearance, it should be high-tech and intelligent, and it should have a cruising range no worse than a traditional SUV!First of all, it's fast.Using 400 horsepower dual motors in the case of two-wheel drive can ensure that the unit power of the vehicle reaches 222 data, and in the case of four-wheel drive, if the four motors work to the limit, it can reach an exaggerated data of 444!That is to say, if we do not follow the usual two-wheel drive situation, but follow the most extreme four-wheel drive condition to accelerate from 2 kilometers to 4 kilometers, then the speed can be changed to more than 3 seconds, and it can reach [-] within [-] seconds. More than a second score, right?This result can definitely scare other suv manufacturers to death!This kind of data is something they can't achieve with a gasoline engine!

Come to think of it, with just four electric motors we can achieve a total of 800 horsepower! 800 horsepower, this is more powerful than the German tank engine during World War II!At the end of World War II.Germany's Maybach claimed to have developed a 1000-horsepower engine, but World War II ended before it could be produced.After World War II, France was fooled by the Germans and was eager to build its own tanks. France, which proved its strength as a great power, bought such an engine solution from Maybach, but it turned out that it couldn't do it by itself!Later, the engineers of Maybach were recruited, and it took a long time to find out that the so-called 1000 horsepower engine could only achieve 800 horsepower in the end!And like the epoch-making t-54\55 tank developed by the Soviet Union, it is said to be such a tank that inspired countries and thus opened the future era of main battle tanks. The engine with a weight of more than 30 tons is only more than 600 horsepower!

And like Cayenne suv, BMW suv, etc., the best engine is only more than 500 horsepower!And the engine horsepower of the suv that Lamborghini claims to build is only 600!And this 600-horsepower engine is already a 5.2-liter engine!But like 2012.Legend has it that the coming year is the 2013th anniversary of Lamborghini in 50. This Lamborghini will launch an extremely limited edition sports car - poison!Such a poison car is said to be limited to 3 units, painted in the three colors of the Italian flag, and priced at 310 million euros, excluding tax.But if there is a competitor, the price will increase—that is, just like an auction, 330 million is just a low price!And 330 million euros was already more than 2000 million yuan at that time!

For such a car, the engine used is only 6.5 liters of displacement, the horsepower is as high as 740 horsepower, and it only takes 2.8 seconds to accelerate to 355 kilometers!The top speed is as high as 1.5 kilometers per hour!And such a car weighs about 500 tons.The unit power is 444 horsepower per ton.And the unit power of our suv is 800, which is four electric motors with 1.8 horsepower driving a 3.8-ton suv. Even if our aerodynamic shape is more resistant than Lamborghini's poison sports car, how can we run to a running score of 1.8 seconds? ?This data is always scary, right?And unless other companies use their top sports car engines on suvs, there is no way to compete with us for points!And don't forget, the weight of 1.4 tons is the weight of our suv fully loaded!In fact, the empty weight should be around [-] tons!So when it comes to unit power, we are no worse than Lamborghini's poison!

And what is the most unfair point in this kind of competition is how much their top engine costs!Among other things, the 5L engine of the BMW x4.8 costs more than 13 units in China!Even if there are less tariffs in the United States, even if he is 10 yuan in the United States, but that is more than 500 horsepower!And an engine that is similar to Lamborghini's 750 horsepower, not to mention 20 yuan, how can it be at least 15 yuan?And what about our motor?The electric motor used in the previous Tesla Highway Star was 142 horsepower, and it cost 1 yuan each!As for the 200-horsepower engine, the price quoted by Tomita is only 1.5 yuan a piece!We use 4 in one car.It's only 6 RMB!

In terms of power source alone, Lamborghini wants to compete with Tesla, and the cost is at least 15, while we only need 6!And this is the cost difference!When it comes to high-end products, let's not talk about taking advantage of cost advantages to fight price wars, and the truly rich will not be so short of money.People are more interested in ability or appearance and a series of things!Then we saved 10 yuan in power source alone and used it in other aspects. Can we throw Lamborghini out of the street in terms of interior, appearance, and even safety?In 2012, the media predicted that the SUV made by Lamborghini would be priced at 17 euros, not to mention that the euro is worth more than the dollar. Jia Hongjian believes that his car will be sold for [-] euros, not to mention the performance Lamborghini's suv is overwhelmed, but at least it can fool the winner, right?Don't forget that Lamborghini's SUVs don't use their poisonous engines!At that time, our [-]-kilometer acceleration score will definitely be much better than Lamborghini's SUV!

At that time, we will achieve the performance of communicating with others at a price that is half as fast as that of others. What will consumers think of this?People who can afford a car of 10 euros or 17 euros.That's certainly not the poor.But being rich does not mean that they are the kind of people who are stupid and earn money quickly!People are willing to spend a lot of money to buy things with higher performance, but it doesn't mean they will spend an extra 7 euros to buy a Lamborghini suv with similar performance to a Tesla suv!At least the Lamborghini brand is not worth 7 euros!Besides, if you can make an SUV that is not inferior to Lamborghini at a cost of 7 euros, then Tesla's name will definitely become a hit all over the world!At that time, Tesla's brand will also be very powerful!Who will be afraid of whom?

On the other hand, things like a large space are beyond Jia Hongjian's decision-this is what the designers below have to do!Many of our designers are recruited from SAIC, FAW, South Korea, Japan, the United States, and the United Kingdom. They are very professional in how to excavate the interior space of cars, but Jia Hongjian is not such an expert.So let them do it!In other respects, it has a domineering sci-fi appearance, that's for sure.Can the appearance designed by Jia Hongjian not be domineering or sci-fi?Our car has a streamlined front, exaggerated bumper, and no air intake. The original air intake is a plowing metal plate like the knight's visor.Coupled with the specially designed domineering side leaking and fierce headlights, it definitely looks like the car is full of domineering.As for the sci-fi feel, in addition to the appearance, all kinds of intelligent devices such as head-up displays inside can certainly make the car look sci-fi!In such a situation.In terms of cruising range, if we can reduce the wind resistance, we can increase the mileage!

Let’s calculate that the traditional suv consumes 12 liters of fuel per 70 kilometers, and the fuel tank volume of many suvs is larger than that of cars. For example, the fuel tank volume of vehicles such as the Highlander is as high as 500 liters!In this case, basically a tank of fuel can drive about 60 kilometers!And something like the Jeep Compass also has a fuel tank volume close to 400 liters.How can you drive at least 1 kilometers?And when Mr. Guo and the others made a prototype of our suv for testing, even if 18650 350 batteries were used, the battery life was only 400 kilometers!And if we can continue to optimize the aerodynamic shape and get a battery life of about [-] kilometers, wouldn't it be perfect?Although it may not be as good as the Highlander and other cars, at least it is not much worse!Besides, if you drive on the highway for more than three hours, you should take a break, right?Even if people are not tired, the people in the car should get down and relax their legs, go to the toilet or something?Therefore, optimizing the shape to reduce wind resistance can be said to be the most important thing in Jia Hongjian's eyes, and it must be done!

So, how to modify it?If the wind resistance of a hatchback is definitely greater than that of a sedan... then can we make an suv into a sedan? (To be continued..)
