It's just that these guys can naturally realize the importance of the buddies in their dorms to themselves and their families. Although we don't see each other much, we do not have a lot of phone contact, on the one hand, to strengthen the relationship between brothers, and on the other hand, to pave the way for their future.

Just like Zhang Lan now, this kid has now appeared at the military vehicle test site dedicated to Alice Group.

In this test site with a variety of simulated terrain and environments, a quirky off-road vehicle is undergoing some of the toughest tests in the world, and the body is already covered in mud, so you can't tell what the original color of the car is.

With the development and growth of Alice Group, every year Alice Group has to launch several new models, waiting for the idle model testing work Zhang Lan naturally will not come here, this car can let Zhang Lan run here from the capital, obviously it is not simple. It's not simple, and in terms of appearance alone, this car is very eccentric.

It is said that this off-road vehicle is strange because although this car also maintains the typical characteristics of off-road vehicle hatchback shape, ultra-high chassis, large approach angle and large departure angle, in terms of appearance, the most significant feature is that there are two more wheels in front of the two wheels in the back, or that the single rear axle that was originally two wheels is now a structure of two rear axles, forming a strange structure of six wheels in a car. It looks a lot like a scaled-down version of a three-axle truck.

And from the appearance, the salient feature of this car is not only two more wheels, compared with the traditional off-road vehicle with only four wheels, the shape of this car is undoubtedly much taller and more powerful, and the mighty shape makes people involuntarily afraid of the steel beast in front of them.

Standing in front of this car, people can't help but feel a little small. Just by visual inspection, it feels like the body length of this car should reach about 5.3 meters, which is 80 centimeters longer than the current off-road vehicle body of about 4.5 meters. It is also 2.2 meters wide, which is not only larger than the Hummer, which is the most iconic off-road vehicle of today, but even larger than the full-size off-road vehicles represented by the most popular in the United States, such as the Ford Diplomat and Lincoln Navigator.

Don't underestimate the extra two wheels, the extra two wheels are definitely not good-looking and showy, the ability of the four-wheel-driven car to pass in the harsh terrain is worse than the six-wheel-driven off-road vehicle; Don't underestimate the 80 cm body, for field workers who need to drive for a long time in the harsh conditions of the field, and need to bring more materials and fuel, a larger body means that they can carry more fuel and more equipment, so that they can work longer and go farther in the field, that is, the task that originally required them to run five times to complete the task is likely to be completed only four times with the support of sufficient materials and equipment.

Zhang Lan is sure that from the perspective of styling alone, there is no doubt that the return rate of this car on the road is more than 100%, and the Ferrari, Porsche, Lamborghini and even Rolls-Royce cars on the road are all killed! It is estimated that many people will wonder if someone drove the armored car here.

The world's six-wheeled vehicles, except for wheeled armored vehicles and wheeled trucks, are basically all military vehicles, the more famous six-wheeled military off-road vehicles are the Israeli desert raiders and the United States has just been built, has not yet been officially put into service SmarTruck super military vehicles. In the civilian market, the six-wheeled off-road vehicle with six-wheel drive is directly absent, and the Alice Group has launched its own six-wheeled off-road vehicle to the civilian market this time, which can be described as ambitious.

"Of course, installing 6 wheels is not only for the sake of good looks, the reason for installing two more wheels is more for the need to strengthen the off-road performance of the vehicle, because if necessary, all six wheels can be used as driving wheels, and the power provided by six wheels is of course much more balanced than four wheels." Xiao Chenxi said to Zhang Lan,...,

"And the six wheels, each wheel with independent suspension, and equipped with a locking system, when any wheel is suspended, the locking system will automatically distribute the power of the suspended wheel to the other wheels that land, even in the worst terrain conditions, as long as one wheel can hit the ground, the car can continue to move forward."

In addition, the car can also quickly switch between the three drive modes of 6X2, 6X4 and 6X6 according to the actual needs, and the conversion process can be easily done by pressing a few buttons on the center console. This setup scheme not only ensures the fuel economy of the vehicle in good road conditions, but also ensures the amazing off-road ability and passability of the vehicle. ”

In addition, the car is equipped with auxiliary systems such as hydraulic winch, central tire inflation and deflation system, powerful towing system, high-strength roof rack, multi-functional combined roof lighting system and so on. I can even say with certainty that there will be no car in the world that is more suitable for working in the field than our car, which is a car born for off-roading. ”

"But with such a heavy body, and six huge off-road tires when necessary, can the car's powertrain provide enough power? If I'm not mistaken, the weight of this car has reached 3 tons," Zhang Lan asked with some concern, "With such a heavy body, if the power used is insufficient, it is a big problem." ”

"Don't worry, I thought about this problem at the beginning, so we equipped this car with a 4.8-liter V-shaped eight-cylinder TDI turbocharged diesel engine," Xiao Chenxi was obviously confident about this question, and when she heard Zhang Lan ask about this question, the little girl seemed full of confidence, "This engine can provide 600 horsepower power output capacity and 1000 Nm after being improved by Brother Zhuzi. m of torque output capacity, it can be said unceremoniously that there is currently no civilian off-road vehicle in the world power system can be more powerful than the power system of this car. ”

"And the average fuel consumption of about 16 liters per 100 kilometers is enough to ensure that this car is the most fuel-efficient car among the current off-road vehicles." After finishing speaking, after thinking about it, Xiao Chenxi added another sentence.

Zhang Lan nodded, this is not bad, compared with the fuel consumption of 16-18 oil per 100 kilometers of Mitsubishi Pajero and 22-25 oil per 100 kilometers of Toyota Land Cruiser, this car can definitely be called a well-deserved fuel-saving pioneer. As for the American-made off-road vehicles? Ahem, forget it, for Americans who have always had deep pockets, they don't know what fuel economy is at all. For the cars produced by Lao Mei, drinking oil is basically equivalent to drinking water, and the only thing you have to do is to keep an eye on the huge fuel gauge on your car at all times, and always remind yourself not to forget to refuel.

Finally, don't forget that whether it is an American off-road vehicle or a Japanese off-road vehicle, the performance of their powertrain is much worse than that of this car.

The power and torque output capacity of this 4.8-liter V-shaped eight-cylinder TDI engine has reached the power and torque output level of the 6.0-liter V-shaped 12-cylinder TDI diesel engine that Volkswagen has just equipped on the Audi A8 car they have just participated in the German Touring Car Masters this year.

Many people may wonder why the performance of a small displacement engine is better than that of a larger displacement engine, in fact, it is not surprising at all, think about the Gas-67 military off-road vehicle equipped by the Soviet army during World War II, The use of a displacement of 3.25 liters of engine, but the power is only a pitiful 54 horsepower, which seems absolutely incredible now, but this is indeed the truth, now a displacement of 3.2 liters of engine, the power can hit more than 180 horsepower anyway, maybe 20 years later, the current displacement of 4.8 liters of engine power can hit an astonishing 1000 horsepower? Who can guarantee this? The reason for all this is nothing more than the degree of technological sophistication. …,

Although Alice Group's ceramic engine and high-power gasoline engine can provide more power to the car, the high cost of the ceramic engine limits the possibility of using the car in the extremely harsh environment in the field, compared to the traditional metal engine is more suitable for harsh field conditions.

Most importantly. The most basic requirement in the use of off-road vehicles is that the leather is durable, and the other meaning of the durability of the leather is that the technical indicators can be poor, but it must be resistant to tossing, and obviously, some delicate all-ceramic engines and gasoline engines are still not able to meet these requirements, relatively speaking, this TDI turbocharged diesel engine is just able to meet the needs, although in the high-end engine sequence of Alice Group, the TDI engine can be called the most mediocre performance of the engine, But compared to Volkswagen's delicate, uneasy and picky TDI engine, this engine is extremely durable:

The vehicle can travel up to 200 kilometers with all the engine oil leaking – and of course the price after that 200 kilometers is the complete scrapping of the engine. However, compared to the complete scrapping of the engine. Obviously, this distance of 200 kilometers represents infinite hope for the staff working in the wild and uninhabited areas;

In the case of engine lubricating oil leakage and oil leakage failure is repaired, you can use any lubricating oil you can find to lubricate the engine, if you really can't find it, peanut oil, rapeseed oil, soybean oil and other edible oils can also be used, not picky at all. This is a supreme artifact for those who work in the field! Countless off-road vehicles have been damaged in the field after the oil pan has been repaired, but the engine refuses to work because of the pickiness of the lubricating oil, which makes people want to go crazy: although there are people living nearby, but the nearest town is hundreds of kilometers away, even if the town may not be able to buy lubricating oil, how to repair this broken car? But now, just go to an inhabited place and buy some cooking oil and pour it in;

You can use the worst quality produced by the small earth refinery like a tractor, and there are many impurities in it, so that people can wonder if this is diesel after all, and there is no need to worry that the engine will protest with a strike like the delicate Volkswagen TDI engine, and the good appetite will make you wonder if you are feeding pigs, because pigs have always been known for not being picky eaters.

But to be honest, Zhang Lan feels that it is a bit of a waste to equip this car with such an excellent engine, but it is a pity that it seems that among the engines suitable for Alice Group, only this engine is the most suitable to be equipped in a harsh environment that works for a long time, and it is very likely to be so bad that it can no longer be harsh in the environment, there are only two engines. The engine was a 3.6-litre V-six TDI engine that only made 280 hp and 590 Nm.

Thinking of the 3.6-liter TDI engine, Zhang Lan couldn't help but move, "By the way, list the 3.6-liter engine as another choice for the power system." ”

"Huh?" Xiao Chenxi was stunned for a moment, then a hint of clarity flashed in her eyes, and she nodded, "Okay." ”

It is foreseeable that when this car is officially launched on the market, for many people, they will not really choose this car to go off-road, but to the extreme personality of this car, for these guys, the 4.8-liter engine is obviously a waste. For this type of potential customer, the 3.6-liter engine will provide enough power for their idle tossing and turning, and for those who do need to toss in the wild. Naturally, they will also understand which engine is best for them.

"How's that, it's not bad, right? Not far away, the off-road vehicle that is being tested is undergoing a difficult off-road performance test, and Xiao Chenxi, who is standing next to Zhang Lan, obviously has the taste of showing off, because this car is designed by this girl, for her own work, the little girl naturally wants to hear praise from Zhang Lan's mouth. …,

"Well, it's tough, although this is only a civilian off-road vehicle for use in extreme environments, even many military vehicles can't reach the level of off-road ability of this car." Zhang Lan nodded, and gave a proper evaluation of the six-wheeled monster in front of him, especially the scene of crossing the river beach road just now, which impressed Zhang Lan: people have to be careful when they walk over, and even the modified snow leopard off-road vehicle does not pass through the steep river beach full of boulders, this off-road vehicle with 6-wheel drive actually passed easily, in addition to being tough, it seems that there is no other suitable adjective to evaluate this car, "If you simply calculate the off-road ability of the wheeled production vehicle, This car should be able to deservedly be called the king of off-roading. ”

Xiao Chenxi couldn't help but feel a little proud. can be praised by Zhang Lan so much, the little girl no longer feels hard about the work she has done before.

"By the way, since the engine air intake is located on the roof of the car," Zhang Lan looked at the car that had just rushed down a big slope and rushed into a pond for wading tests, and couldn't help but be a little curious, "Then the wading depth of this car should be more than 1 meter, right?" A lot of words "Even the U.S. military Humvee, which is known for its strong off-road ability, has a wading ability of less than 1 meter, and the size of this car is much more powerful than the Humvee, whether it is the body height, engine height or chassis height is higher than the Humvee, so in any case, the wading depth of this car must be more than 1 meter, right?" Not a lot of words

"Well, if you don't consider the water temperature, the wading depth can reach 1.5 meters, but in late autumn or winter and other low water temperature conditions will not work, wading and traveling, the water will definitely not pass the floor of the cab, probably not many people are willing to put their bodies into such a low temperature of minus a few degrees in winter," looking at the car not far away, Xiao Chenxi smiled, "But this problem is not too big a problem, we also equip this car with a water travel system, With a little preparation, this car can move quickly on the water like an amphibious vehicle such as an armored car, and although the load in the car will definitely be soaked in water on the floor, the depth of immersion on the floor is only about 20 centimeters at most, and it is not a big problem to lift your feet. ”

"Damn!" Zhang Lan only has one sentence to express her feelings:

A car that can travel on water? Wouldn't that be called an amphibious vehicle? It seems that there are no such mass-produced cars in the world at present, and the few that occasionally appear are just tossed by those crazy car enthusiasts themselves, and the price is still too high.

As for the military armored vehicles that can travel on water, in addition to the fact that they can provide greater buoyancy and better control of the center of gravity by sealing themselves, the most important reason is that the vehicle is also equipped with a drainage system to ensure that the dead weight and buoyancy of the vehicle are always maintained at a sufficient level. If this car is reliable for water travel, this alone will be able to occupy a considerable special off-road vehicle market at home and abroad.

"Master Wang, please test our water travel system." Seeing that Zhang Lan seemed to be very interested in this, Xiao Chenxi called out to the tester who was testing the vehicle through the walkie-talkie.

"Understood." After a pause, a slightly hoarse voice sounded on the walkie-talkie in Xiao Chenxi's hand.

Zhang Lan stared at the car that had just climbed up to the pond not far away, and was a little curious: how did this car move on the water? At present, the more mainstream method is to reduce the weight of the body, increase the seal in the car to increase the buoyancy of the car body, but the weight of the car itself has reached 3 tons, from the action of the body when wading just now, the water seal of the car is basically equal to zero, so how does the car do it on the water? Could it be that it takes a long time to prepare like a tank dive? …,

It turned out that Zhang Lan, this kid, was completely overthinking, and overcomplicated the simple question, and the car that was about to travel on the water stopped on the shore, turned around, and the driver of the car got out of the car and quickly opened a small door similar to a small toolbox, about 15 centimeters high and 25 centimeters long, from the small door, pulled out a shriveled plastic object from the small door, and at the same time took out a one-quarter trachea from the toolbox carried by the car. Four gas distributors are attached to the plastic objects located in the four doors, and the other is connected to the car's own air pump that inflates the tires.

What is it? Zhang Lan was a little curious: inflatable air bag? Using airbags to provide buoyancy to the car? That's a good idea, but it seems that there are still a lot of problems to be solved in this thing, and this girl has been solved together?

At the same time as the inflat, the tester was not idle, first took out the power of the external paddle wheel structure used on the steam-powered ship before the appearance of the six marine propellers from the toolbox and stuck it on it through the card holders reserved on the six wheels, so that without any modification of the car's power system or adding any additional mechanisms, the car has a propulsion system similar to that of a marine paddle wheel, which is much more efficient than paddling by wheels alone.

"Clever!" Seeing this paddle wheel instead of a propeller, Zhang Lan couldn't help but exclaim, "It's so handsome!" ”

Although the paddle wheel is inferior to the propeller in terms of propulsion efficiency, the role that six paddle wheels can play is not much different from that of two small speedboat propellers. And if the propeller is used, there is an additional set of transmission system, there are many parts, and there are many possibilities for failure. Comparatively, this method of directly attaching the paddle wheel to the wheel hub is more reliable.

"Thank you." Xiao Chenxi nodded with a smile, obviously very useful for Zhang Lan's praise.

After finishing the work of fixing the paddle wheel, the tester was not idle, and then opened the rear tailgate and came out of it a small bundle of more than 1 meter long, probably stainless steel pipe, squatting on the ground and tinkering, not knowing what to do.

After the four plastic products slowly swelled to a certain extent, Zhang Lan saw clearly that the four plastic items taken out of the four doors turned out to be very good folded air bags. The inflator pump on board was obviously very strong, and it didn't take long for the four airbags to be filled with bulging sacs, and the overall appearance was flat and oval. The four airbags were so large that even the window glass on the four doors was blocked, and it was obviously not a problem to float on the water with the three-ton car......
