Latest Q&A
Q
What is the advantage of 4 wheel steering?
The main advantage of four-wheel steering systems is that they enhance a vehicle's maneuverability and high-speed stability. Especially on narrow roads or tight turns, the rear wheels can pivot slightly in the same or opposite direction as the front wheels based on the steering angle. This reduces the turning radius, making parking, U-turns, and similar maneuvers much easier—you’ll really notice the difference in city alleys or crowded parking lots. At highway speeds, the rear wheels turning in phase with the front wheels boosts lane-change stability, minimizes body roll, and gives drivers more confidence. Plus, these systems optimize tire grip distribution, delaying understeer or oversteer to adapt to different driving scenarios. Right now, some high-performance and luxury models come with this tech, but as electronic control systems advance, four-wheel steering could become more widespread, even trickling down to more mainstream family cars. It’s worth noting that these systems usually work hand-in-hand with electronic stability programs, so during regular maintenance, make sure the sensors and wiring are in good shape to keep everything performing at its best.
Q
Is a 4x2 the same as a 4x4?
4x2 and 4x4 are two distinct drivetrain systems, with key differences in power distribution and vehicle usage. 4x2 means two-wheel drive, usually front or rear-wheel drive, ideal for daily city driving—it offers better fuel economy and more affordable maintenance costs. On the other hand, 4x4 stands for four-wheel drive, where power can be sent to all four wheels, delivering superior traction and off-road capability. It’s great for rough terrain or rainy, slippery roads, though it tends to have higher fuel consumption and a steeper purchase price. Among common local models, pickups and SUVs often come with 4x4 options, while sedans are mostly 4x2. When choosing, think about your actual needs: if you frequently drive in rural areas or mountains, 4x4 is more practical; but if you mainly commute in the city, 4x2 is a better value. Plus, some 4x4 models feature part-time or full-time four-wheel drive systems, allowing you to manually or automatically switch drive modes based on road conditions, further boosting driving flexibility.
Q
Why did they change 10 and 2 to 9 and 3?
Drivers used to be taught to keep their hands at the 10 o'clock and 2 o'clock positions on the steering wheel. That setup was based on the design of older vehicles without power steering, where those positions provided more leverage to turn the wheel. But with advancements in steering technology, especially the widespread adoption of power steering, turning the wheel no longer requires that much effort, so driving posture has changed. These days, it's more recommended to place your hands at the 9 o'clock and 3 o'clock positions. There are a few benefits to this: first, this posture reduces fatigue during long drives because your arms can rest more naturally on the wheel; second, in the event of a collision, if the airbag deploys, this position helps prevent your arms from getting injured by the airbag; additionally, it offers better steering precision, especially at high speeds or in emergency situations. It's worth noting that modern steering wheel designs have adapted to this change—many models feature ergonomic grooves or protrusions at the 9 and 3 o'clock positions for more comfortable grip, and some performance cars even add paddle shifters there, further highlighting the importance of the 9 and 3 o'clock positions. This shift is an optimization based on safety research and real-world driving experience, and drivers are advised to adapt to this new, correct posture as soon as possible.
Q
What does 4 * 2 mean in cars?
In automotive terminology, 4×2 refers to a vehicle's drive type, where the "4" stands for four wheels and the "2" means two of those wheels are driven. This setup is commonly called rear-wheel drive (RWD) or front-wheel drive (FWD), depending on which wheels are powered. Rear-wheel drive is typical in performance-focused cars or commercial vehicles because it offers better power distribution and traction, especially when hauling loads or climbing hills. Front-wheel drive, on the other hand, is more common in economy cars—its simpler design and space-saving layout boost fuel efficiency and make daily driving more convenient.
By comparison, 4×4 (four-wheel drive) is better for tough terrain like mud or slippery roads, but 4×2 is totally sufficient for regular roads and city driving, plus it’s cheaper to maintain. When choosing a drive type, think about how you’ll really use the vehicle. If you mostly commute in the city, 4×2 is more than enough. But if you frequently tackle rough terrain, you might want to consider a 4×4 model. Also, the drive type affects fuel economy and handling—front-wheel drive cars steer more nimbly, while rear-wheel drive is better for drivers who want a more engaging, fun-to-drive experience.
Q
When should I use 4WD high or low?
The high gear (4H) and low gear (4L) of the four-wheel drive system need to be selected according to the road conditions. 4H is suitable for wet and slippery roads or mild off-road conditions, such as rainy roads, gravel roads or muddy terrain, which can enhance traction and allow high-speed driving, while 4L is used for extreme terrain, such as steep slopes, deep sand or rock climbing, to enhance the ability to escape by amplifying torque, but low-speed driving is required to avoid overloading the transmission system. When switching, the vehicle needs to be parked in neutral, and some models also require manual locking of the differential. It is worth noting that long-term use of 4H on paved roads may increase fuel consumption and component wear, while misuse of 4L for high-speed driving can lead to mechanical damage. Therefore, it is important to understand the recommendations in the vehicle manual. In addition, modern four-wheel drive technologies such as full-time four-wheel drive or on-demand four-wheel drive can automatically distribute power, but traditional part-time four-wheel drive still requires manual switching. It is recommended to operate flexibly according to actual needs, and regularly check the transmission system and tire condition to ensure performance.
