What does the abbreviation 'RWD' stand for in automotive terms?

In automotive terminology, RWD stands for rear-wheel drive. In an RWD vehicle, the engine’s power is transmitted to the rear wheels, while the front wheels primarily steer the car.

The classic arrangement places the engine at the front and mounts it longitudinally, with a driveshaft carrying power to a rear differential. This layout was once standard for many cars because it works well with larger engines, balanced weight distribution and performance-oriented handling. Rear-wheel drive also remains common in sports cars, luxury sedans, pickup trucks and many larger vehicles.

Front-wheel drive sends power to the front wheels, while all-wheel drive can deliver power to all four wheels. Four-wheel drive is related but usually refers to a system designed for greater traction in off-road or demanding conditions.

The first front-engine, rear-wheel-drive car is often identified as an 1895 Panhard, whose layout became known as the “Système Panhard.” Modern electric vehicles have also helped renew interest in rear-wheel drive.
