How to Distinguish Between Front-Wheel Drive and Rear-Wheel Drive in Cars?

The differences between front-wheel drive and rear-wheel drive lie in space, sharp turning conditions, center of gravity angle, and appearance. The specific differences are as follows: 1. Front-wheel drive uses a transversely mounted engine positioned more forward, providing more interior space; rear-wheel drive uses a longitudinally mounted engine, which can encroach on interior space. 2. Front-wheel drive cars have a heavier front and lighter rear, making them prone to understeer during sharp turns; rear-wheel drive cars have a lighter front and heavier rear, making them prone to oversteer during sharp turns. 3. When encountering steep slopes, front-wheel drive cars have their center of gravity angle at the front, making them more likely to slip when climbing; rear-wheel drive cars perform much better in this regard. 4. Front-wheel drive models have a longer front overhang and are more commonly seen in sedans (including micro and economy cars); rear-wheel drive models have a relatively shorter front overhang and are commonly used in large and medium-sized buses.
The most intuitive way to distinguish between front-wheel drive (FWD) and rear-wheel drive (RWD) is by looking at the engine layout. Open the hood—if the engine is mounted transversely (sideways), it's most likely a FWD vehicle where power is directly transmitted to the front wheels. This design saves space and is more cost-effective, which is why most family sedans are FWD. If the engine is mounted longitudinally (lengthwise), extending from the front toward the cabin, it's probably a RWD car that sends power to the rear wheels via a driveshaft. Also, check the interior space: RWD cars have a significantly higher center hump in the rear floor due to the driveshaft running underneath, while FWD cars have a much flatter middle section. Another clue is weight distribution—RWD cars handle corners more stably because the weight is more evenly balanced between the front and rear.
The driving feel is the most noticeable difference! With front-wheel drive, you can feel the steering wheel tug during acceleration, especially prone to understeer in rainy conditions. Rear-wheel drive gives an exhilarating push at launch, but be cautious of oversteer in snowy weather. Engine sounds differ too - rear-wheel drives have a distinct driveshaft whine. Tire wear patterns also tell them apart: front-wheel drives chew through front tires faster since they handle both steering and driving forces, while rear-wheel drives wear out rear tires more aggressively. My previous Civic was front-wheel drive, and now I drive an older 3-series with rear-wheel drive - the handling difference is massive, with rear-drive offering far more precise cornering.
The simplest way to distinguish is by brand positioning. Daily commuter cars are mostly front-wheel drive, such as the Corolla and Sylphy, which have simple structures and lower costs. Rear-wheel drive is commonly found in luxury cars and sports cars, like the BMW 3 Series and Mustang. In terms of space layout, front-wheel drive cars have more foot space in the rear seats, while rear-wheel drive cars often have trunk space occupied by the drive shaft. The drive method affects the center of gravity; front-wheel drive cars have about 60% of their weight on the front, making them prone to understeer, whereas rear-wheel drive cars have a more balanced front-to-rear weight distribution. Additionally, there's the turning radius—front-wheel drive cars are more agile when making U-turns, while rear-wheel drive cars require more space.
