What is the function of a car spoiler?

The functions of a car spoiler are: 1. During high-speed driving, it generates downforce, providing the car with greater grip, effectively reducing air resistance generated at high speeds; 2. It offsets part of the lift, controls the car's tendency to rise, reduces the impact of wind resistance, allowing the car to adhere closely to the road, thereby improving driving stability; 3. It enhances the aesthetic appearance of the car. The car spoiler is located on the trunk lid and is part of the car's aerodynamic kit. Structurally, it is divided into single-layer and double-layer types, made from materials like aluminum alloy and carbon fiber. Additionally, they can be manually adjusted or hydraulically auto-adjusted, with the latter featuring hydraulic columns that automatically adjust the angle based on the car's speed.
When driving on the highway, I noticed how effective the rear spoiler is. It's like giving the car small wings—at high speeds, it generates downforce, pressing the car firmly onto the road and reducing lift or skidding, especially noticeable during cornering and lane changes. I once experienced this while speeding on a mountain road; the spoiler made a huge difference, keeping the car stable with strong grip and lowering the risk of accidents. It also helps in windy or rainy conditions by preventing mud from splashing onto the rear window and obstructing visibility. While it slightly increases drag and affects fuel efficiency, it's indispensable for performance or modified cars focused on speed. Overall, a spoiler isn't just for looks—it enhances safety and performance, making me feel much more secure on the highway.
