A 2.0T medium-sized off-road SUV has a comprehensive fuel consumption of only 8.83L(WTCL comprehensive fuel consumption) per 100 kilometers, which was absolutely impossible in the past, but Jietu travelers did it.
As a comparison, the comprehensive fuel consumption of WTCL for tank 300 with the same level and size, but the price is one level higher than that of travelers, reaches 9.9L per 100 kilometers. Jetway travelers are larger in size, higher in power and lower in fuel consumption than tank 300, which is an interesting and core car cost issue.
Big body, high power and low fuel consumption, how do Jietu travelers do it?
After more than 20 years of grinding a sword, Kunpeng Power Sword refers to the whole world.
Some people may say that it doesn’t matter if the fuel consumption is 1 liter per 100 kilometers, it’s a matter of a few dollars. But if you look at it in a year, you can save thousands of dollars in gas money every year, which is not a small expense.
By way of digression, in Management Economics, we discussed such a question: Will the increase of oil price lead to the decrease of oil consumption? The answer is: in the short term, the oil consumption of car owners is basically the same, because the travel demand is fixed. However, if we put the time scale into five or ten years, we will find that the oil consumption is significantly decreasing.
In other words, fuel cost affects the long-term decision-making of car owners, and most car owners will become more and more sensitive to fuel consumption. So until today, one of the main research and development lines of major automobile manufacturers is still to reduce fuel consumption.
In order to reduce the fuel consumption by 0.1L per 100 kilometers, it even needs to invest hundreds of millions and billions of R&D costs-Chery Group, which is famous for its image as a technology emperor and a science and technology man, was originally famous for its dead engine technology.
Continuous R&D investment has brought rich returns to Chery Group. Kunpeng Power, which has been grinding a sword for more than 20 years, leads the world in energy consumption, stability and power.
Jietu Traveler is fully equipped with Kunpeng Power, which originated from the "global power architecture of Chery 4.0 era" and is the masterpiece of fuel power solutions. Traveler’s fuel version has three power options: 1.5TD-7DCT, 2.0TD-7DCT and 2.0TD-8AT.
Among them, 2.0TGDI Kunpeng Power adopts the third generation engine independently developed by Chery, with a maximum power of 187kW and a peak torque of 390N?m, which is the strongest 2.0T in China, and its power reserve is equivalent to a 3.5L V6 engine. In contrast, the 2.0T power of the tank 300 is only 167kW, which is 10% lower than that of the Voyager 2.0T model, but the fuel consumption is more than 10%. 85% of the travelers’ owners choose the 2.0T model.
This is the result of Chery’s continuous research and development of technology for ten years, and it has become an "engine expert" with absolute advantage today. This 2.0T engine won the "China Heart" Top Ten Engine Award. In order to drain the energy of every fuel, it adopts a special structural design and integrates the world-leading technologies such as I-HEC II intelligent combustion system, Miller cycle, fully integrated ultra-low friction technology and super transient response power system.
More importantly, it only needs to add 92 # gasoline, which can save a lot of fuel consumption.
"De-girder" not only reduces fuel consumption but also improves driving comfort.
It has been the consensus of research and development in the automobile industry for decades that the "dead knock" in technology and material research and development can often bring unexpected advantages.
Jietu travelers use high-strength materials to improve the torsional stiffness of the car body and replace the girders with the "de-girder" design, which not only ensures off-road performance, but also reduces the weight of the car body and fuel consumption.
In order to improve the rigidity of the body, conventional off-road vehicles generally adopt non-load-bearing body with girder structure, and even in rugged terrain, the door and body will not be deformed. Jietu also pursues the rigidity of the car body, and can also achieve the effect of car body invariance, but it removes the girder and adopts the way of using ultra-high strength materials.
Jietu Voyager adopts submarine-class body, with high-strength steel accounting for 80%, and adopts integrated laser tailor welding. The torsional stiffness of the whole car body reaches an astonishing 31 000 N m/deg, which is the same level as Land Rover Defender, and at the same time, the comfort is greatly improved.
Using high-strength materials to design girders brings two major benefits to Jietu travelers. One is to reduce the weight and fuel consumption as mentioned above. The other is that after removing the girders, the whole vehicle adopts a load-bearing body and is independently suspended in front and rear, which greatly improves the comfort of the whole vehicle and even gets the ride experience of urban SUVs. At the same time, after the isolation between the car body and the wheels is removed, the car body is more sensitive to the control of the wheels, more agile, and the sense of control is obviously improved.
Although the girder is removed, the off-road performance of Jietu travelers is still good. In terms of hardware, its body has 28 approach angle, 30 departure angle, 220mm minimum ground clearance and 700mm wading depth.
In addition, the car is equipped with XWD fully-automatic intelligent four-wheel drive system. Through the cooperative work of the central intelligent torque manager and the intelligent slip-limited differential lock at the rear axle, it can switch between 2-wheel drive and 4-wheel drive in 0.1 second according to different road conditions. Ordinary unpaved roads, sand, mud and snow can be easily handled, and U-shaped cross shafts and bullet holes can pass through, which has the advantages of the passability of off-road vehicles and the excellent comfort of SUVs.
In the current fierce market competition, you can’t go far without your own core technology. Backed by Chery Group, a "technology emperor" and "technology man", Jietu travelers are already ahead of friends in technology, and with the accurate travel positioning based on users’ needs, it is difficult to think about it. In fact, fuel consumption is only one of the advantages, and this car has more detailed advantages worth exploring.
