What is the difference between four-wheel drive and two-wheel drive in cars?

[Leslie]

The differences between four-wheel drive and two-wheel drive in cars are as follows: 1. Different driving methods: Two-wheel drive refers to the front or rear wheels of the car acting as the driving wheels, while the other two wheels remain as passive wheels. Two-wheel drive can be further divided into front-engine rear-wheel drive, front-engine front-wheel drive, rear-engine rear-wheel drive, and mid-engine rear-wheel drive. Four-wheel drive means all four wheels are driving wheels. Four-wheel drive is generally categorized into: on-demand four-wheel drive, part-time four-wheel drive, and full-time four-wheel drive. 2. Different fuel consumption: Four-wheel drive systems consume more fuel than two-wheel drive systems. On-demand four-wheel drive consumes one or two more liters per hundred kilometers compared to two-wheel drive. 3. Different stability: Four-wheel drive can distribute the engine power to all four wheels, providing stronger handling, better passability, and greater stability compared to two-wheel drive. It is suitable for complex road conditions such as off-roading, while two-wheel drive is more suitable for simpler urban road conditions.
