The challenging plateau extreme environment is the most rigorous testing ground for off-road vehicles. As a representative of off-road field, Toyota Land Cruiser is famous for its long history and strong off-road ability, and is deeply loved by senior off-road players. As a new cross-country species, Dongfeng Warrior 917 not only inherits the cross-country genes of military warriors, but also incorporates intelligent electric technology, successfully opening the luxury road of hard-line cross-country. On the plateau, who is better between the two? Only after the comparison will we know!
Power system competition, whose performance is stronger?
In the off-road field, Toyota Land Cruiser has always been known for its powerful performance and reliability. It is equipped with a 4.0L V6 naturally aspirated engine with a torque of 385 Nm. However, in the plateau area, this car has encountered obvious challenges. Due to the high altitude, thin air and low air pressure in the plateau area, the engine intake of Land Cruiser is significantly reduced and the fuel combustion is insufficient. This directly led to a sharp decline in its dynamic performance, and the original strong power became soft and weak on the plateau.
In contrast, Dongfeng Warrior 917 provides more diversified power options, including pure electric version and extended range version. The pure electric version adopts a four-motor four-wheel drive system, with a horsepower reserve of up to 1088Ps, and the acceleration time of zero hundred is only 4.2 seconds, which can maintain strong power output even in the plateau environment. The extended-range model is equipped with three motors and a 1.5T range extender, with a horsepower of 816 horsepower and a CLTC comprehensive cruising range of 1,026 kilometers. Because the range extender is not directly involved in driving, the power is slightly affected by the altitude change, providing stable and sufficient power in the plateau area.
Who can provide more comfortable driving experience in suspension system competition?
Suspension system plays an important role in vehicle performance, comfort and passability. The rear axle of Toyota Land Cruiser adopts dependent suspension (integral bridge type). Although this structure can provide better bearing capacity and passability under complex road conditions, when driving at high speed under continuous potholes, the overall bumpiness of the vehicle is relatively strong, which affects the ride comfort.
Dongfeng Warrior 917 is equipped with AeroRide multi-stage intelligent adjustable air suspension from BWI Jingxi, equipped with 5-speed adjustment, supporting 150mm long-stroke suspension height adjustment, supporting 45mm downward adjustment and 105mm upward adjustment, which can realize multi-body attitude adjustment, support body height adjustment, body height maintenance, easy loading, suspension welcome function, and take into account multiple requirements of off-road, fuel economy and convenience of boarding and descending. The maximum ground clearance of 335mm can be reached in the extrication mode, which brings strong road trafficability.
Steering system competition, who can bring better handling?
Today, with the continuous innovation of automobile technology, the performance of steering system directly affects the driving experience of vehicles. The R-EPS electric power steering system adopted by Dongfeng Warrior 917 has higher steering efficiency than the common EPS system of ordinary off-road vehicles. At the same time, the R-EPS electric power steering system has stronger axial load capacity. This makes the steering system of Dongfeng Warrior 917 work stably and maintain good handling performance when it bears a large load and impact, which provides a strong guarantee for the reliability and safety of the vehicle.
In sharp contrast, the traditional hydraulic power steering system adopted by Toyota Land Cruiser. Due to the characteristics of its mechanical structure, it may increase the driver’s driving fatigue when driving for a long time or needing frequent steering operations. More crucially, in the plateau environment, the hydraulic power steering system is facing severe challenges, and hydraulic oil pipes and other components are prone to air resistance, which will directly affect the working performance of the system, resulting in slow and inaccurate steering response, and may even endanger driving safety in severe cases.
Brake system competition, braking can only play wild.
Toyota Land Cruiser is equipped with mechanical hydraulic braking system, which is famous for its stable and reliable braking torque. However, in this special environment of plateau area, due to high altitude and large temperature difference between day and night, these extreme conditions put forward a severe test for the performance of hydraulic oil. In low temperature environment, the fluidity of hydraulic oil becomes worse, which may lead to the slow response speed of the braking system, thus affecting the braking effect; However, at high temperature, the hydraulic oil pipe is prone to air resistance, which further reduces the braking efficiency. These problems not only affect the driving comfort, but also affect the driving safety to some extent.
Facing the challenge of plateau environment, Dongfeng Warrior 917 adopted a more advanced IBC hydraulic brake-by-wire system. This innovative technology directly controls the braking system through electronic signals, and accurately controls the flow and pressure of hydraulic oil, thus achieving accurate control of braking force, which significantly improves the braking effect and safety. Compared with the mechanical hydraulic braking system, the brake-by-wire system has faster response speed and higher sensitivity, and can respond to the driver’s braking instructions more timely.
Who is the more reliable travel companion in the security competition?
In the automotive field, safety has always been one of the core elements that consumers are most concerned about. Toyota Land Cruiser adopts TNGA architecture, the body is welded by laser, and the frame is mainly made of high-strength steel. This kind of steel has excellent tensile strength and yield strength, which can effectively absorb and disperse energy during collision and protect the safety of occupants in the car. In addition, the key parts of the car body, such as A-pillar, front pillar and roof beam, are reinforced with multi-layer structure and high-strength steel plate to further improve the rigidity and anti-collision ability of the car body.
Dongfeng Warrior 917, as a luxury electric off-road vehicle, adopts the technology of ultra-high-strength internal high-pressure integrated molding of longitudinal beam pioneered by non-loaded off-road vehicle in China, and uses high-pressure water medium to close the cavity for expansion, which can make the longitudinal beam stable in size, without weld, welding scale and welding slag, and welding thermal deformation. Due to the cold work hardening effect of expansion, the strength of parts is improved by 10% compared with the strength of materials. The frame structure is made of high-strength materials, and the coverage rate of high-strength materials from 600~800Mpa to 800 MPa is more than or equal to 85%. The high coverage rate ensures the strong and durable performance of the car body and ensures superior passive safety protection.
Four-wheel drive system competition, who has stronger ability to get rid of difficulties?
As we all know, the ability to get out of trouble is one of the core indexes for verifying off-road vehicles. As an evergreen tree in off-road field, Toyota Land Cruiser’s full-time four-wheel drive system has always been its proud capital, and it has won the favor of many consumers with its excellent comfort, stability and long-distance crossing ability. However, the domestic version of the Land Patrol lacks the front and rear differential locks in the four-wheel drive configuration, which makes it slightly inadequate in the face of extreme off-road conditions.
In contrast, Dongfeng Warrior 917 is equipped with electronically controlled mechanical differential lock and central virtual differential lock, which can achieve 100% mechanical locking, which not only improves the efficiency of torque transfer, but also ensures the stability and passability of the vehicle under extreme conditions. This configuration allows the Warrior 917 to face all kinds of complex terrain with ease and easily challenge extreme off-road conditions.
At the same time, Dongfeng Warrior 917 is the only vehicle in China that has passed the durability test of "National Military Standard" (GJB). After four rounds of military standard durability test, the total mileage exceeds 1 million kilometers, and the actual mileage of equivalent users is nearly 6 million kilometers, covering 99.5% of user usage scenarios. Among them, off-road working conditions, mountainous areas, mining areas and other extreme working conditions account for as much as 50%, ensuring that vehicles can maintain reliable operation under any circumstances, showing excellent reliability and durability.
With the continuous progress of science and technology, the automobile industry is undergoing changes. Dongfeng Warrior 917 has become a new dark horse in the off-road field with its advanced technology configuration and excellent performance, and has also set a new benchmark for domestic off-road vehicles. Traditional fuel off-road vehicles, such as Toyota Land Cruiser, may also need continuous innovation in technology to cope with the ever-changing market demand and environmental challenges.
