Strong motivation and light weight： Interpretation of Land Cruiser LC300
Analysis of product characteristics;Silicone oil fan engine produced in 2021!
On the new generation LC300, Toyota has prepared three powertrains for it, all of which use silicone oil fans as the cooling scheme. ! This may be the only mass-produced new car with silicone oil fan in the 21st century! You know, even the brand-new fourth-generation Jimny gave up the silicone oil fan …
Two newly developed V6 twin-turbo engines (3.5L gasoline and 3.3L diesel) based on TNGA platform can surpass the traditional V8 engine in performance. The 3.5T V6 version of gasoline (code V35A-FTS) has a power of 415 HP, a torque of 650 Nm, and an acceleration of 0-100km/h of 6.7 seconds! (Another Mammoth) The other is a diesel 3.3T V6 engine (code F33A-FTV) with a maximum power of 309 HP and a torque of 700 Nm. Both power systems will be equipped with 10AT automatic transmission.
In addition, in some areas with low emission requirements.(Say goodbye to us completely)LC300 continues to provide the 1GR-FE 4.0L V6 engine that is "classic and super-resistant and not picky about food", with a maximum power of 275 HP and a maximum torque of 385 nm, matching the 6AT gearbox.
Tips: silicone oil fan
In fact, many people are very, very unfamiliar with silicone oil fan, because it really only appears on some traditional and old-fashioned off-road vehicles. Unlike today’s electronic fans, it doesn’t have so many sensors, and it can’t adjust and open the fan in time according to the water temperature. It is more primitive! It determines whether to enter the working state and stage according to the characteristics of engine speed.Generally speaking, it belongs to the type of "turning more and more", just like the red-headed machine adopted by Honda S2000, but you can’t always turn up the speed to get cool instead of commuting, can you?The silicone oil fan is similar. In congested cities and some low-speed environments, its heat dissipation performance is difficult to guarantee, but it can provide strong heat dissipation performance and high reliability in some high-speed crossing environments or desert environments.
Many people think that the silicone oil cooling fan is a product of the last century, and it is rarely used in gasoline engines now, and it is hard to see it in today’s new generation of hardliners. It originally belongs to a mechanical temperature control fan, powered by the crankshaft pulley of the engine, and driven by a belt to rotate the silicone oil cooling fan. When it is started, it can hear a loud noise. It is this silicone oil fan that makes people look askance, as if it is a large displacement. The off-road vehicle uses a silicone oil fan, but the focus is on its reliability.
Analysis of product characteristics;Introducing transparent chassis /MTS all-terrain system
Transparent chassis is nothing new. From the propaganda of Land Rover in the early days, people can understand the concept of transparent chassis. Through the intervention of cameras, vehicles can have more observation dimensions when traveling off-road. Through the screen, we can get the road conditions in real time, which can play a great auxiliary role in judging the route and avoiding danger. The familiar Toyota MTS all-terrain system can automatically choose the best driving mode according to the transmission of road conditions.Adaptive Variable Suspension (AVS) can calmly face all kinds of complicated road conditions.The all-terrain selection system also adds Zita Law and automatic mode,The crawling system has also been re-optimized, and the speed can be controlled in the off-road process. Combined with the transparent chassis, the land patrol LC300 has realized the intelligent off-road experience in line with the current mainstream trend.
Analysis of product characteristics;Welding technology of non-load-bearing body/brand-new frame
From the chief engineer’s mouth, we can see that they have a lot of pride in the land patrol with TNGA-F platform. The land patrol LC300 is the first mass-produced vehicle with non-load-bearing body under TNGA framework, and its frame has undergone a brand-new welding process, and a lot of weight reduction work has been done on the premise of ensuring strength. The welding of the body frame is no longer connected by traditional overlapping welding, but is approximately "seamless fusion" on a plane.
In addition, in order to change the heavy front of the previous generation Land Patrol, the engineer adjusted the position of its engine gearbox, and the height dropped by 28mm, while the whole body moved back by 70mm, and the front and rear weight reached 53.5:46.5, which is undoubtedly a very positive and important change for a large hard-core SUV model. The change of center of gravity and overall weight will greatly affect its driving performance in various road conditions.
Analysis of product characteristics;E-KDSS system/second generation TSS system
What is KDSS?KDSS is not magical, but it is indeed a unique martial art of Toyota. It is a hydraulic self-adaptive adjustable balance bar system, which can be regarded as a kind of active suspension. The sensor will predict your driving environment and road conditions according to a series of dimensions such as vehicle speed and left and right compression of the car body, and adjust the hardness of the balance bar in real time, thus affecting the car body roll and suspension stroke.
Once the system senses that the vehicle speed is high, the KDSS hydraulic shock absorber will become hard, and the support of the original vehicle suspension will be improved by changing the hardness of the balance bar. If you feel that the vehicle speed is low, for example, if you cross the road and the left and right wheels expand and contract, the pressure difference of KDSS oil shock absorber will become softer, and it will be easier to release the stroke, so that the four wheels can touch the ground as much as possible, increase the friction and reduce the appearance of cross shafts.
But in fact, for those professional players who really use land patrol to play cross-country, the biggest drawback of KDSS is that it affects the vehicle’s elevation. If the elevation does not exceed 2 inches, the operating range of KDSS will be stretched to the limit, and then it will fail. The alarm light will always be on, and the after-sales maintenance and replacement cost of KDSS is not low, just tens of thousands of pieces. Even if you want to tear it down, you need a series of matching and re-purchasing new balance bars, and the price is also very expensive. so~ Unless you are a targeted professional group, there is absolutely no need to have too many ideas about KDSS. It is a way to have both, not to pursue the extreme in a certain direction, and it is enough for most people.
On the new generation of land patrol LC300, this system has become an electric control system. Obviously, its sensitivity, response speed and accuracy will be significantly improved, and its sensitivity to road changes will be better, which is worth looking forward to.
The land patrol LC300 is also equipped with the second generation Toyota Safety Sense, which enables it to have better safety early warning performance in urban environment and pavement environment.Compared with the previous pre-collision system, two new functions have been added;Help avoid collisions or reduce injuries by detecting pedestrians and cyclists during the day and night.
The first realization scenario is to detect oncoming vehicles and pedestrians crossing the road when the vehicles turn in any direction. The second realization scenario is: the active lane keeping and collision prevention system is not sophisticated, but for a hard-core model with classic heritage, the increase of these auxiliary configurations will undoubtedly make it have better active safety performance in paving environment and highway. In addition, the land patrol LC300 is also equipped with a parking assistance system, which can identify obstacles or pedestrians in the rear during parking, which is very necessary for "it is so huge".
Analysis of product characteristics;Driving assistance/comfort adaptation
In addition to the above parts, the land patrol LC300 has been improved in many details, such as changing the inclination angle of the shock absorber again. After being tested and adjusted by Dakar drivers,Combined with these changes and optimizations, the new model will have more comfortable and faster steering performance and handling, and its directivity and vibration filtering performance will also be improved.In terms of comfort in the car, the land patrol LC300 also has pursuits, such as; With the adjustment of the seat position, the steering wheel will also be adjusted to bring more comfortable driving experience and reduce the driver’s fatigue.
On the brand-new land patrol LC300, NVH performance is highlighted. Take the 3.3T diesel as an example. Even when driving fast in a non-paved environment, people in the front and rear rows of the car can easily talk at a normal volume. Just as Toyota said, they hope that this car can not only take you anywhere, but also drive and use it more easily in a paved environment, and minimize fatigue.
Editor’s Summary: Inheriting the Initial Heart & Trying to Break the Circle
TNGA-F, non-load-bearing, new welding technology, silicone oil fan … These actions are not just about paying tribute to classics or selling feelings. I believe Toyota is well aware of the significance of land cruisers to Toyota brands. It can be seen that Toyota has tried its best to retain the characteristics and soul of land cruisers in research and development, so that it can continue to gallop anywhere in the world.
The blessings such as E-KDSS, MTS and TSS make it more in line with the comprehensive needs of the new era. Even if you are a tough guy, you will not forget your tenderness. Let more people have and like it is something Toyota must do, not just land patrol, but what every "off-road vehicle" wants to do and is doing today. After all, who doesn’t want it to be sold to more and wider people? Look at Big G, look at herdsman, look at Tank 300 … Which one doesn’t think so?
Next, let’s have a static real car. Although we really don’t know the exact situation of the version of the Bank of China and parallel imports at present, I suggest you can look forward to it. (Text/car home Ren Bo)
