The Beijing BJ80 employs a part-time four-wheel drive system. Part-time four-wheel drive allows the driver to manually switch between two-wheel drive and four-wheel drive modes by engaging or disengaging the transfer case. Taking the 2020 Beijing BJ80 as an example, it is a mid-to-large-sized SUV with the following dimensions: length 4765mm, width 1955mm, height 1985mm, and a wheelbase of 2800mm. The 2020 Beijing BJ80 is equipped with a 2.3T turbocharged engine, delivering a maximum horsepower of 231PS, a peak torque of 345Nm, and a maximum power output of 170kW. It is paired with a 6-speed automatic transmission.

As an automotive repair technician, I frequently work on the Beijing BJ80. This vehicle employs a part-time four-wheel drive system rather than a full-time setup. This means it operates in rear-wheel drive mode during normal city driving, helping owners save on fuel and costs. However, when encountering rugged mountain roads, snowy surfaces, or muddy terrain, simply manually switching the control lever or button engages four-wheel drive mode, distributing power to all wheels for improved traction and off-road capability. The BJ80's system is robustly designed, featuring a transfer case for torque distribution, while the optional differential lock adds extra capability in extreme off-road conditions by locking wheels to minimize slippage. For maintenance, I recommend checking the transfer case fluid every 10,000 kilometers to prevent leaks and ensure system longevity. Overall, this four-wheel drive system is practical for those who enjoy occasional adventures or live in areas with variable climates, offering both economy and reliability.

As an owner of the Beijing BJ80 for nearly two years, I find its part-time 4WD system particularly suitable for daily use. During weekday commutes, I use the rear-wheel drive mode which is fuel-efficient and quiet, making the vehicle perform similarly to a regular sedan with fuel consumption around 10L/100km. However, when taking family trips to the countryside on weekends or encountering slippery roads during rainy days, I manually switch to 4WD mode. The vehicle instantly feels much more stable, eliminating concerns about wheel spin during acceleration or struggling on inclines. The system operation is straightforward with a switch conveniently located near the steering wheel, requiring no technical expertise. For maintenance, I simply follow the manual for routine servicing – the system has been trouble-free after fluid changes. This vehicle performs excellently both in urban and off-road conditions, offering noticeably enhanced safety, especially for families with young children.

Hey, all off-road enthusiasts know that the Beijing BJ80 uses a part-time 4WD system, which is super cool! When I take it to the desert or mountains, I manually switch to 4WD mode, and the tire grip is incredibly stable. Climbing up or down slopes feels like walking on flat ground, and I never have to worry about getting stuck. The smart design lies in its default rear-wheel drive for fuel efficiency, avoiding unnecessary waste. After switching to 4WD, the transfer case balances power output between the front and rear axles, and the optional differential lock is a lifesaver in muddy conditions, enabling hardcore escapes. I’ve tested it in rain and snow, and it performed flawlessly. The vehicle is rugged and durable, with easy maintenance—I just check it every six months. For thrill-seeking drivers, the BJ80’s 4WD opens up endless adventure possibilities.
