Is Audi's On-Demand Four-Wheel Drive Normally Front-Wheel Drive or Rear-Wheel Drive?
1 Answers
Audi's sedan lineup all adopts a longitudinal front-wheel drive platform, so the on-demand four-wheel drive system defaults to front-wheel drive under normal conditions. Below are the differences between front-wheel drive and rear-wheel drive vehicles: 1. Engine Configuration: Rear-wheel drive vehicles mostly use a longitudinal engine layout, while front-wheel drive vehicles employ a transverse engine layout, which saves considerable space. 2. Handling Characteristics: Front-wheel drive vehicles require the front wheels to handle both steering and driving, placing a greater burden on them. In contrast, rear-wheel drive vehicles, due to the heavier rear axle and greater inertia, are more prone to oversteer (tail sliding). 3. Fuel Consumption: Rear-wheel drive vehicles experience power loss through the driveshaft, making them less fuel-efficient compared to front-wheel drive vehicles.
