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