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

[JuneRose]

Front-wheel drive vehicles typically have the front wheels positioned farther from the front bumper (due to the transverse engine layout, which prevents the engine from being installed too far forward), while rear-wheel drive vehicles have the front wheels closer to the bumper. Rear-wheel drive vehicles feature a longitudinal engine layout, which doesn't interfere with the front wheel arrangement. To achieve better handling, the front wheels are positioned as far forward as possible. Below are key differences between front-wheel drive and rear-wheel drive vehicles: 1. Front-wheel drive vehicles generally have lower manufacturing costs and a more affordable entry price, which is why most compact cars (A-segment) and mid-to-low-priced midsize cars (B-segment) are front-wheel drive. 2. Compared to rear-wheel drive vehicles, front-wheel drive models integrate the main reducer, differential, and other transmission components into the gearbox, eliminating the need for a driveshaft to the rear wheels. This results in higher power transmission efficiency, lighter body weight, and better fuel economy. 3. In front-wheel drive vehicles, major components like the engine and drivetrain are concentrated at the front, leading to lighter rear weight distribution. The front wheels handle both steering and driving functions, causing more severe wear. Additionally, front-wheel drive cars exhibit more noticeable body lift during acceleration and nose-dive during braking, making them more prone to understeer issues.
