Laboratory test: WEY tank 300, which can rotate around the tank, is not a "three locks" at all.

The test model we got this time is WEY? Tank 300? 202 1 off-road version of 2.0T conqueror is also the top version of tank 300 for the simple reason that the passenger seat of this car is electrically adjustable-this is the only feature of the top version. The official pre-sale price of this configuration version is 2,654.38+0.38 million yuan. Although it has not been listed yet, the dealers are already selling at this pre-sale price. To tell you the truth, I think this car is worth the price.

Before this, the hard-core off-road vehicles in China market were actually divided into three factions. The first is the independent "low-end faction". In China, as long as you are in your early 80s, you can own a four-wheel drive SUV with your own brand. The part-time four-wheel drive system has many advantages, one of which is "low cost".

Second, Land Rover Range Rover, a high-end group composed of Mercedes-Benz G, is characterized by high price. It's better to pretend to be a B than a person-because after so many years, no one in the cross-country circle is willing to drive a big G or a Range Rover.

The third is the "wild school" represented by Suzuki Jimny and Jeep Shepherd. This school was built for cross-country, but on the paved road, its overall driving quality is extremely poor.

If there is a hard-core SUV, it has 90% off-road performance of Jeep Shepherd, and the road driving quality is comparable to that of urban SUV. At the same time, the technology is not inferior to Land Rover and the luxury is not inferior to Mercedes-Benz. In terms of car networking, it also has the world's advanced level, and the final price cannot be too expensive ... At present, only WEY tank 300 can meet the above conditions at the same time.

What's more, some off-road capabilities of the tank 300, such as "tank turning around", don't even have "field warriors" like Jimny or shepherd. In cross-country circles, this thing is called "one-sided braking". The first time I came into contact with this thing was when I ran a rainforest cross-country race with a group of Malaysian boys on 20 10. Its function is to shorten the turning radius and facilitate the racing car to shuttle through the rainforest.

The Malay unilateral brake control handle is designed under the steering wheel, which is more like a turn signal. At any speed, the steering wheel can be turned on at any position, which is very dangerous and has high technical requirements for drivers. The principle of unilateral braking of tank 300 is actually to implement separate electronic control of parking braking, and there is no way to achieve constant saturation; On the other hand, a set of brake calipers is added to the rear wheel of the competitor's pneumatic mechanical single-sided brake, which can realize the constant locking of 100%, that is, as shown in the following figure, two sets of brake calipers can be seen on the rear wheel.

There is also a more powerful one, which can lock the front and rear wheels on the same side, so as to realize a small lateral movement on the wet road surface-emphasizing lateral movement rather than steering! However, this kind of front and rear single brake system is not common even in cross-country circles.

Besides, there is a rumor here. Some media said that the "tank turning" unilateral brake was invented by the Japanese. In fact, Toyota has applied this technology for no more than 65,438+00 years. Volvo applied this technology to RAPTGB in 1950s. On the 9 15 military vehicle, this military vehicle is called TP2 1 in Volvo. However, at that time, Volvo developed this technology not to "turn the tank around", but a low-cost solution to get rid of difficulties-if one side of the driving wheel slips or idles, as long as this wheel is locked, it can deceive the open differential to transmit power to the other side of the wheel.

RAPTGB? 9 15 looks like the body of the old four-door beetle will be installed behind the hood of the Jiefang truck. Because it's ugly, RAPTGB? 9 15 got a cross-country sow (Terr? Ng-sugar)”。 However, the off-road performance of this car is really strong, so it has also circled a lot of die-hard powder in Europe-there is even a proper term "Suggan (sow man? ) "to refer to this group of diehard fans.

In addition, many media said that the tank 300 is "three differential locks in the front, middle and rear", and these media don't understand cars at all-sorry, Bogo is so straightforward.

Differential lock, to put it bluntly, is "differential lock". For example, Mercedes-Benz 4MATIC full-time four-wheel drive, front, middle and rear three groups of differentials, naturally need to install three differential locks. However, WEY Tank 300 is a part-time 4wd model. When switching to the four-wheel drive gear, the front and rear torque distribution is fixed at 50:50, and the front and rear axles are completely hard connected. Without a central differential, there is naturally no central differential lock. Part-time four-wheel drive models around the world, even Magic Change and Shepherd, have "two locks" in front and back.

Theoretically, two-lock part-time four-wheel drive has better off-road capability than three-lock full-time four-wheel drive-after all, full-time four-wheel drive has no advantage over part-time four-wheel drive in simplicity, reliability and torque load limit.

Because there is no central differential, the part-time 4wd four-wheel drive high-speed gear, that is, the "4H" gear, will be dangerous if it is used on the expressway. Full-time four-wheel drive like Mercedes-Benz 4MATIC has no hidden danger of high-speed four-wheel drive because of its own central differential. As for how to use the "4H" of part-time 4wd, I will talk about it later.

For Tank 300, part-time 4wd is of course the best choice. However, I still hope that WEY official website will delete the words "central differential lock" and "three locks"-I understand what WEY officials want to say is that after the part-time four-wheel drive is switched to the four-wheel drive mode, the front and rear axles are hard connected, which is equivalent to a differential lock, just like having a differential lock. However, in any case, not all media are professional, and consumers' understanding will be biased if the media is misunderstood.

Tank 300 is a good car, but official website's news is still a bit inaccurate.
