You have had an Indian summer in the past, and you know how warm it is when you get out of the door when it is 45 degrees; it would feel like walking into an oven, opening the car door. Have you ever wondered what would happen to your car if you parked it in the sun? In this curious experiment, we determined to discover with our own eyes.
The Experiment: Parked at Noon, 45°C and Full Sunlight
Our experimental vehicle was a mid-sized sedan, which was parked in an uncovered area at around noon, with temperatures recorded at 45 degrees centigrade, which isn't uncommon in cities such as Delhi, Jaipur or Nagpur from May through June. The windows were closed, the engine was turned off, and no shades were provided.
Three thermometers were installed in the car's interior, one on the dashboard, one on the passenger side, and one in the backseat.
After 30 Minutes: The Oven Effect Begins
According to thermal studies from the National Weather Service and San Francisco State University, interior car temperatures can jump by 20–30°C within 15–30 minutes, even when it’s only 35°C outside. In our 45°C test, the dashboard shot up to well over 70°C within the first half hour. The steering wheel became almost untouchable, reaching around 65°C.
At this point, just sitting in the car felt suffocating. The air was dry and thick, and seat surfaces felt like hot metal plates. Imagine how hard your AC must work after such intense heat buildup!
After 1 Hour: The Cabin Turns Dangerous
At the one-hour mark, the air inside the car was above 80°C, almost twice the temperature outside. The dashboard and seats were even hotter. This happens due to the glass window trapping visible light from the sun, which gets converted to infrared energy, or heat, that cannot escape easily.
This level of heat can cause serious damage:
-
Dashboard cracking and fading
-
Leather seats are drying and peeling
-
Plastic parts warping or releasing toxic fumes
-
Electronics are malfunctioning, including touchscreens and dash cameras
And let’s not forget - leaving children, pets, or elderly people in a parked car, even for a few minutes, can be fatal. At just 50°C, a child’s body can overheat in 10–15 minutes.
After 3 Hours: A Full-Blown Furnace
The interiors of the car were like an open furnace that had absorbed the heat of the rays of the sun after three consecutive hours. The temperature gauge showed an internal temperature of 92°C, the air temperature was 83 °C, and even the heat radiated by the steering wheel could easily burn anyone coming into contact with it.
The car’s glossy black paint also absorbed heat, raising the roof temperature significantly. The difference between shaded and unshaded cars can be as much as 25–30°C, according to studies and real-world data shared by quiksnap.us.
Even after switching the engine on, it took nearly 12 full minutes of air conditioning to bring the cabin to bearable conditions.
How to Keep Your Car Cool in Indian Summers
Good news! Here are a couple of measures that you can adopt to avoid heat damage to your car:
-
Install sunshades correctly – Reflective shades will reduce the temperature on the dashboard to some degree, as much as 30°C.
-
Park in reverse – Park such that the sun hits the rear window instead of the dashboard and steering wheel.
-
Ventilate – Crack one window open and bang the other door two or three times to allow the hot air out.
-
Choose light colours – Lighter shades of leather seats, such as beige and tan, are better by about 10 to 15 degrees Celsius.
-
Avoid plastics – Avoid leaving any plastic things in your car, as they can either melt or emit fumes.
-
Cover your car – An important way to protect your car from overheating is through a car cover.
Articles from Neodrift’s summer guides also recommend using seat covers and sunshades to prevent overheating of both the vehicle and the engine.
Smart Car Accessories Built for Indian Heat
Before we conclude, let’s talk about a simple way to protect your car: investing in Neodrift’s car accessories. From water-resistant car covers and custom sunshades to dashboard and floor mats and car organisers, Neodrift designs everything specifically for Indian weather conditions.
These cover products protect your car from the harsh sun rays, dust, and even rain throughout the seasons. The sun shades, which work magnetically, will ensure that the UV rays are kept away as well. If you take your vehicle’s longevity seriously, Neodrift accessories are among the smartest investments you can make this summer.
Conclusion: Heat is Certain - Harm is an Option
One thing we learned in our experiment at 45 °C was that you should never underestimate the power of the sun. Within a few minutes, a parked car can transform into a death trap to anyone in the car, including humans, animals and even the car itself.
The only thing you can do to protect yourself is to be prepared. Find a shade to park, cover yourself against the sun and secure your interiors. It could be the dry weather of Delhi or the humid weather of Chennai, but reasonable manners and good products of Neodrift will rescue you.
