How to Identify Front-Wheel Drive and Rear-Wheel Drive Cars?

[DiSamuel]

Distinguishing between front-wheel drive (FWD) and rear-wheel drive (RWD) vehicles is straightforward. Simply squat down and check if there is a differential on the rear axle. If the rear axle lacks a differential, it's a front-wheel drive car. If the rear axle has a differential, it could be either a rear-wheel drive or a four-wheel drive vehicle. If the front wheels have half-shafts, it's a four-wheel drive car; if not, it's a rear-wheel drive car. Below are related introductions: 1. Front-engine, Front-wheel Drive (FF): This configuration, where the engine is placed at the front and drives the front wheels (abbreviated as FF), is prevalent in sedans (including mini and economy cars) but is rarely used in trucks and buses. 2. Layout of FF Cars: FF cars typically feature a transversely mounted engine connected to a compact transaxle. This layout is widely used in passenger vehicles with engine displacements below 2.5 liters. 3. Rear-engine, Rear-wheel Drive (RR): In this setup, the engine is placed at the rear and drives the rear wheels (abbreviated as RR). It's a popular arrangement for large and medium-sized buses, and is also used in a few mini or economy cars, but is seldom seen in trucks.
