Bitauto Original In the previous test drive experience, Fangbao Automobile Leopard 5 demonstrated its super off-road capabilities, whether it was climbing, shell craters or cross-axles, it seemed to be able to do so with ease. There is no need to open the differential lock additionally, so why does the Leopard 5 have such strong off-road capabilities?
The DMO super hybrid off-road platform is the core, which integrates a hybrid-specific non-load-bearing body structure, front and rear double-wishbone independent suspension, off-road-specific longitudinal 1.5T high-power engine, and front and rear dual motors with electronic differential Powerful off-road equipment such as speed locks, energy center locks, and CTC battery-chassis integration, what sparks have come out of the collision after their integration?
"Leopard Power" overcomes all obstacles
Leopard 5 is equipped with an off-road-specific longitudinal 1.5T high-power generator and front and rear dual motors, with a maximum power of 505kW and a maximum torque of 760N·m. The power is comparable to a 5.0T engine. It also has a traction force of 32000N. This power level has been subverted. It sets a new peak for mainstream hardcore off-road vehicles.
The entire power system is mainly electric drive. In the new energy era, the engine is no longer the only criterion for measuring power level. The DMO super hybrid off-road platform, a combination of engine + generator with front and rear dual motors, is different from previous power The architecture is completely different.
At the same time, since the motor directly drives the wheels, the vehicle computerThe torque distribution between the front and rear wheels can be adjusted at any time to achieve fineness and sensitivity. For example, when climbing, traditional hardcore fuel-powered off-road vehicles need to continuously control the throttle to maintain traction in order to pass, which also tests the driver's experience and skills, but the Leopard 5 electric drive The way is easier, just step on the accelerator lightly, and the vehicle can pass easily.
And on the plateau, the electric-driven Leopard 5 has better power output stability. The motor will not cause obvious power decline due to lack of oxygen or temperature, while traditional fuel vehicles will have more obvious "high reaction". ".
Not only that, electric drive has another major advantage, which is that it has more playability. For example, the front and rear wheels can run in different directions, which also creates a new "leopard-style U-turn".
New car experience, high horsepower and low fuel consumption
What everyone is most concerned about is whether such a powerful Leopard 5 will consume a lot of energy? In our understanding, when compared with traditional off-road vehicles, such as Prado or Tank 300, the fuel consumption of 100 kilometers in urban areas can easily exceed 10L/100km.
But Leopard 5 can bring a new car experience. Leopard 5 can be used as a pure electric SUV. The 31.8kWh battery can support it to travel 125km on pure electricity. Even if it is running low on electricity, the fuel consumption per 100 kilometers is as low as 7.8L/100km, and the comprehensive endurance can easily exceed 1200km, which is already a very strong performance for a hardcore off-road vehicle with such strong power.
In off-road conditions, the engine of traditional fuel-powered off-road vehicles will continue to maintain high speed and low speed during off-road conditions, which means the engine is always working in the most uneconomical condition, and the fuel consumption can easily exceed 20L/100km.
At this time, the advantages of electric drive of Leopard 5 can be more reflected. When the power output is at low load, the engine will not start at all, soTherefore, there is no additional energy consumption. Only when the battery power is low during long-distance travel or long-term off-roading, the engine will start. At this time, the off-road-specific 1.5T high-power engine paired with a 150kW generator can fully guarantee the power. It will not decay, and fuel consumption will not increase significantly at this time.
Powerful power naturally requires a good platform to fully exert its capabilities, and at this time, we have to mention the non-bearer architecture brought by DMO.
Two benefits from one "plate", taking into account safety and off-roading
The chassis of Leopard 5 is based on a new hybrid non-load-bearing architecture. It is also equipped with CTC battery-chassis integration technology, which integrates the battery and the chassis, allowing the blade battery to provide stronger rigidity to the chassis, and the torsional stiffness of the chassis is comparable. It is 38% higher than the traditional girder structure.
And because the battery is in the chassis, the center of gravity of the vehicle is lower, and the front and rear axle load ratio is also 50:50. The benefits of the golden axle load ratio are also obvious, the center of mass is more stable, whether in daily driving Or off-road, the vehicle has better stability.
In terms of suspension structure, Leopard 5 also adopts a double wishbone structure that is more suitable for off-roading, which can provide more sensitive dynamic response and a larger up and down swing stroke.
In order to provide stronger passing ability, Leopard 5 is equipped with three intelligent differential locks, of which the front and rear locks are electronic differential locks, which are intelligently controlled through the wheel speed difference, locking and exiting in real time, and the response speed is faster.
Energy lock can be understood as a set of driving logic, which can fix the output power of the front and rear motors to achieve the effect of synchronous torque output. When it recognizes tire slippage on the front and rear axles, it can complete the front and rear axle control in 10ms. Energy distribution is 30 times faster than a mechanical differential lock, and in extreme working conditions, it can distribute energy more accurately, reduce slipping, and improve passing capacity.
Yunnan-P standard version intelligent hydraulic body control system empowerment
Only having the above-mentioned hardware foundation is not enough. Leopard 5 offers Yunnan-P version as an option. Leopard 5 equipped with Yunnan-P standard version of intelligent hydraulic body control system has stronger passing ability.
First of all, it gives the vehicle the ability to lift. The maximum ground clearance can be increased from 220mm to 310mm, and the wading height can be increased from 700mm to 790mm. Secondly, it gives the chassis the ability to adjust the softness and hardness. By controlling the flow rate of the oil, it can be adjusted The softness and hardness of the suspension make off-road travel more comfortable.
Then there is the four-wheel linkage leveling capability. When encountering situations such as shell craters and cross axles where the wheels cross the ground, the suspension can actively extend, allowing the wheels to actively get closer to the ground to increase adhesion and help the vehicle escape.
This is not the same as the Wrangler's disconnectable connecting rod. Although the Wrangler can also disconnect the connecting rod when encountering a cross axle to achieve the purpose of the wheel sticking to the ground, the wheel load is small when disconnected and the road grip is The ability is limited, but the active extension of the Leopard 5 can synchronize the load and provide stronger grip.
Finally, there is the camping leveling capability. When parking on uneven ground, the vehicle will calculate the horizontal position and automatically extend the suspension in the depression to level the vehicle automatically. At this time, sitting in the car will be more comfortable.
Summary
The Fang Baobao 5 uses electric drive to reach a new level in off-road SUVs. The electric drive-based DMO technology can make consumers more relaxed and burden-free whether in daily use or off-road. Pure electric vehicles can be used for daily driving. mode, low cost, strong power, and quieter. When going off-road, feel free to be wild and leave all the difficulties to the car. It also brings longer battery life. It can be said that the Leopard 5 is really a hardcore off-roader. disruptor, is also a new species in the hardcore SUV market!
