翻译: Front-wheel drive has advantages over rear-wheel drive.Because the engine and transmission components in a FWD vehicle are packaged compactly at the front of the car,the use of interior space is more efficient.Thus,a relatively small car can have a reasonable amount of room inside for passengers and luggage.In addition,the weight of the FWD powertrain (engine and transmission)is directly over the driving wheels.This positioning helps to increase traction on slippery surfaces.
