What does the approach angle of a car mean?

The approach angle of a car refers to the angle between the tangent line drawn from the frontmost protruding point of the car to the front wheels and the ground when the car is fully loaded and stationary. In other words, it is the maximum angle between the horizontal plane and the plane tangent to the outer edge of the front wheel tires (under static load). Any rigid component fixed to the vehicle in front of the front axle must not be below this plane. The approach angle of a car is one of the indicators used to measure its off-road capability. A larger approach angle reduces the likelihood of the front end scraping the ground. However, the approach angle parameter alone does not entirely determine a vehicle's off-road capability or passing performance; other parameters and actual conditions must also be considered. The approach angle is not only important for SUVs; sedans also require a certain level of passing performance. Situations such as driving onto curbs, small steep slopes, or ferries can be encountered in daily use, and a larger approach angle helps prevent the front end from scraping the ground.
As a novice driver who doesn't drive much, I recently heard about the term 'approach angle' for cars. Simply put, it's the maximum angle at which the front of your car can safely climb a steep slope. On overly steep slopes, the front bumper may scrape the ground. The higher this number, the better the vehicle's off-road capability. For example, when my friend took his SUV on mountain trails, vehicles with larger angles could easily handle rocky slopes, while regular sedans would often scrape their undercarriage. It's measured by the angle between the center of the front wheel and the lowest point of the front bumper, with 20 to 30 degrees generally considered good. When parking near steep curbs, you should pay attention to this - don't risk damage by carelessly driving up slopes. Understanding this can save you from repair headaches. I'm even considering checking this parameter before buying a used car.
As an avid off-road driver, I often ponder how the approach angle is a crucial indicator of a vehicle's off-road capability. It refers to the maximum slope angle a car's front end can handle without scraping the undercarriage—essential for climbing hills or fording rivers. A larger angle is generally better; SUVs typically have over 30 degrees, allowing the front wheels to lift earlier and avoid getting stuck on rough terrain. I once tried driving a low-angle sedan up a steep slope, only to damage the bumper. Later, I switched to a modified vehicle with an improved approach angle, and it handled rough roads effortlessly. Practical driving requires balancing ground conditions—too large an angle isn't always ideal, as it may overstress the suspension. This experience taught me to regularly check tire size and ground clearance during maintenance to protect the approach angle.
