What are the symptoms of high-altitude sickness in cars?

[Hunter]

The symptoms of high-altitude sickness in cars include the following: 1. Power reduction: Due to the low oxygen content at high altitudes, fuel combustion is incomplete, leading to a decrease in power. The extent of this reduction varies depending on the vehicle's condition and the road conditions. It is generally more noticeable when climbing slopes compared to driving on flat roads, and more pronounced in poorly maintained vehicles than in well-maintained ones. 2. Difficulty starting in some vehicles. 3. High-altitude vapor lock: Some pressurized fluids (such as brake fluid) containing trace amounts of air may not show issues at lower altitudes, but as the air pressure decreases at high altitudes, they can expand, directly affecting performance and even posing dangers. 4. Coolant overflow or boiling over. 5. Increased tire pressure: Normal tire pressure at lower altitudes will rise as altitude increases and air pressure decreases. If not adjusted in time, this increases the risk of tire blowouts. 6. Reduced fuel consumption in gasoline-powered cars: Air resistance at high altitudes is about 20% less than at lower altitudes.
