Haval H9 four-wheel drive system is similar to the all-terrain system found in Land Rover models, featuring six terrain modes: Sand, Snow, Mud, AUTO, Sport, and 4L. The system can automatically control driving force and braking force to achieve optimal driving and braking performance. Among these, the 4L low-range four-wheel drive mode can amplify torque by 2.48 times during off-road driving. Taking the 2020 Haval H9 2.0T Gasoline 4WD Elite 5-seater as an example: this vehicle is manufactured by Great Wall Motors, classified as a mid-to-large SUV, with a gasoline energy type, equipped with an 8-speed automatic transmission, and configured as a 5-door, 5-seat SUV.

I've been driving the Haval H9 SUV for three years, and its four-wheel drive system is what gives me the most peace of mind while driving. Simply put, the engine can distribute power to all four wheels, unlike regular front-wheel or rear-wheel drive vehicles. When driving on regular roads, I switch to 2H mode for better fuel efficiency. But if I encounter rainy weather or icy roads, I switch to 4H, and the vehicle's grip immediately improves, reducing the risk of skidding or slipping. On weekends, when taking my family on trips to the suburbs and encountering muddy terrain or steep slopes, I engage the 4L low-range four-wheel drive mode, where the high torque helps the vehicle climb easily. The Haval H9 uses a TOD intelligent four-wheel drive system, which automatically detects wheel slippage and distributes more power to the rear or other wheels as needed. For routine maintenance, I regularly check the drive shafts and fluids to ensure the system operates smoothly. Although driving in four-wheel drive mode consumes slightly more fuel, the added safety and reliability are absolutely worth it. Remember, avoid using four-wheel drive on dry, flat roads for extended periods, as it may accelerate wear on components.

From a technical perspective, the four-wheel drive system of the Haval H9 is essentially a mechanism that distributes power to all wheels, and I'm quite fascinated by this type of design. It features a part-time four-wheel drive system with multiple modes: 2H is the two-wheel drive mode, ideal for daily city driving, offering fuel efficiency and environmental friendliness; 4H, or high-speed four-wheel drive, is suitable for rainy, snowy, or slippery roads, automatically adjusting torque; 4L, or low-speed four-wheel drive, provides maximum traction during off-road driving. The system primarily relies on a central differential and sensors—if the front wheels slip, power is immediately redirected to the rear wheels. Compared to full-time four-wheel drive, Haval's system is more intelligent and energy-efficient. I've personally tested mode switching on snowy terrain, and the response was impressively quick. A downside is that if the sensors malfunction, such as inaccurate wheel speed data, it could affect performance, so it's important to regularly check electrical connection points. Regular maintenance of the drive axle can help avoid major repairs.

After years of teaching driving lessons, I've found that four-wheel drive systems are crucial for driving safety. The 4WD system in the Haval H9 distributes engine power to all four wheels, enhancing vehicle stability. When instructing students, I always remind them to activate 4H mode during rain, snow, or mountain driving - the improved tire grip reduces the risk of losing control during sharp turns or sudden braking. However, this system doesn't completely eliminate dangers; it must be combined with proper tires and reduced speed. Regular maintenance checks are essential as the dustproof and waterproof components are prone to damage. Developing good driving habits significantly improves safety.
