Do Good Cars Also Get Hot Inside in Summer?
4 Answers
Good cars are generally equipped with heat-insulating and UV-protective glass, which indeed makes the temperature inside not as hot. Solutions for high temperatures inside the car in summer: Use a cooling spray. The main component of cooling sprays is dry ice, and the cooling effect is excellent. Open the car door and spray it around; reducing the temperature by 20 degrees in 1 minute is no problem at all. Open the diagonal windows or open three windows for ventilation. When it comes to opening windows for ventilation, many people's first reaction is to open all the windows. However, this method is not very effective for heat dissipation. The correct way is to open the diagonal windows or close one side window while opening the others, which provides better heat dissipation. The role of car air conditioning: This is the main function of car air conditioning. In summer, the cooling system produces cold air to lower the temperature inside the car. In winter, except for large commercial vehicles that use independent combustion heaters for heating, other vehicles basically use the car's residual heat for heating.
In summer, my car is considered quite good, equipped with automatic air conditioning and insulated glass. However, I've noticed that even after parking it outdoors in the sun for just an hour or two, the interior becomes unbearably hot. Once, after a trip to the supermarket, the car's thermometer showed 45 degrees Celsius when I returned, and the steering wheel was too hot to touch. I think this is normal because sunlight coming through the windows heats up the interior objects, much like a greenhouse. While the air conditioning in a good car cools down quickly, it still takes a few minutes after starting to feel the coolness. So, I recommend finding a shaded spot to park or buying a high-quality sunshade to block the windshield. Additionally, if the car has been parked for a long time, open the windows for a few minutes before getting in to let the hot air escape before turning on the AC. Overall, no matter how good the car is, the heat inside during the hot summer months is unavoidable—the key lies in how you handle it.
From my perspective, even good cars can get quite hot in the summer, and this isn't related to their air conditioning systems but rather determined by physical principles. The car's glass absorbs a significant amount of solar heat, and materials inside like seats and dashboards also store thermal energy. Even with a powerful AC, it can't instantly remove all the heat. I usually pay attention to small details: for example, leaving a small gap in the window for ventilation when parked, or using a mobile app to remotely start the AC in advance, making it much more comfortable when getting in. Additionally, many new cars now come with smart cooling features that automatically adjust based on temperature, but any car parked in the sun on a hot day will take some time to cool down. The key is not to overlook this, as accumulated heat can potentially affect the longevity of seats and electronics. In short, with some simple tricks like using sunshades or opting for garage parking, you can better manage the interior temperature.
As a seasoned driver with years of experience, I can tell you that in summer, whether it's a good or bad car, parking outdoors can make it feel like a steamer. My experience is that darker interior colors absorb more heat, so choosing light-colored seats and windshield sunshades can help. After parking for half an hour and getting back in, you'll always feel a wave of heat hit you. Don't rush to turn on the AC—first, open all the windows to let the air circulate and dissipate the heat. Then, start the engine and wait a few minutes before turning on the cold air, which saves fuel and is more effective. Remember, regularly cleaning the AC filter can maintain cooling efficiency, but hot weather is unavoidable.
