Which is More Fuel-Efficient: Front-Wheel Drive or Rear-Wheel Drive?

[Enid]

Front-wheel drive vehicles are more fuel-efficient compared to rear-wheel drive vehicles. Detailed information is as follows: 1. Front-wheel drive vehicles have fewer mechanical components, resulting in reduced weight, which naturally leads to better fuel efficiency; the engine in front-wheel drive vehicles is closer to the drive wheels, providing higher power transmission efficiency and better fuel economy; therefore, front-wheel drive vehicles are more fuel-efficient than rear-wheel drive. 2. Rear-wheel drive vehicles experience reduced front-wheel load during startup, acceleration, or climbing, leading to decreased traction; the power transmission in rear-wheel drive vehicles requires going through a driveshaft, which consumes more power and thus makes them less fuel-efficient than front-wheel drive vehicles.
