What does AWD mean on a car?

AWD on a car refers to All-Wheel Drive, which is the abbreviation for All-Wheel Drive. It means that the engine distributes power evenly to all four wheels through the transmission mechanism. This power distribution method is commonly used in SUVs, off-road vehicles, racing cars, and high-end sedans. In particular, AWD offers strong handling capabilities and excellent traction, reducing the likelihood of understeer and wheel slippage. FWD stands for Front-Wheel Drive, where the engine primarily distributes power to the front wheels to propel the car forward. The advantages of front-wheel drive include improved steering dynamics, better front-to-rear weight distribution, and superior acceleration performance.
AWD stands for All-Wheel Drive. This system distributes engine power to all four wheels simultaneously, providing driving force to each wheel. Compared to regular vehicles that only have front-wheel or rear-wheel drive, AWD is particularly useful in rainy or snowy conditions, as it reduces the likelihood of skidding when cornering. Last time I drove my friend's AWD SUV in the mountains, the wheels didn't spin at all when going uphill on icy roads. However, fuel consumption is slightly higher for daily city driving since all four wheels require power. If you frequently drive on snowy roads or engage in outdoor activities, it's important to check for this feature when choosing a car.
Simply put, AWD is a system where all four wheels drive together. When I was buying a car, the salesperson explained that this system includes a transfer case and a center differential, allowing power to be distributed between the front and rear wheels in varying proportions. For example, during rapid acceleration, more power is sent to the rear wheels to prevent front-wheel slip; during high-speed cornering, the outer wheels rotate faster. Nowadays, many urban SUVs with AWD are quite fuel-efficient because they primarily use the front wheels for driving, and the rear-wheel power only engages when sensors detect slippage. However, for serious off-roading, you’d need a rugged 4WD system with differential locks—ordinary AWD can’t handle deeper mud. When choosing a car, it’s important to distinguish between part-time and full-time four-wheel drive.
