What is the plastic panel at the front of a car called?
2 Answers
The plastic panel at the front of a car is called a spoiler, primarily designed to reduce the lift generated when the car is traveling at high speeds, thereby preventing the rear wheels from lifting off the ground. If a car lacks a spoiler, during high-speed driving, the difference in air pressure between the upper and lower surfaces naturally creates an upward lifting force. This not only consumes the car's power but also directly affects driving safety. When a car reaches a certain speed, the lift force can overcome the car's weight, lifting it up and reducing the adhesion between the wheels and the ground, making the car feel unstable and decreasing driving stability. To minimize the lift generated at high speeds and reduce the air pressure beneath the car, it is necessary to install a spoiler.
The plastic panel at the front of a car is commonly referred to as the bumper cover. In automotive design, its primary function is to protect both the vehicle and pedestrians, such as absorbing impact during low-speed collisions. Did you know? Most modern cars use plastic materials like polypropylene for this part because it's lightweight, helps reduce overall vehicle weight (improving fuel efficiency), and lowers production costs. However, plastic panels are prone to scratches or cracks, especially during parking scrapes. I recommend regularly inspecting its condition – if damaged, repair it promptly to prevent rainwater ingress that could cause internal rust. When washing your car, use a soft cloth and pH-neutral cleaner, avoiding stiff brushes to prevent surface scratches. Maintenance costs are generally low, with replacement parts typically ranging from a few hundred to a thousand yuan depending on the model. This component is integral to the bumper system and crucial for road safety – never overlook it!
