How Hot Can a Car Get?

Justin Lee | 5 months ago | Featured|Newest|Remote Start

Summer is here – which means summer vacation, sunny weather, long days, and ice cream! However, all of these things also mean HOT, HOT, HOT weather.

Hot weather is not only uncomfortable, but it can also be dangerous – especially inside of a vehicle. Did you know that the inside of a car can get 30º hotter than the outside within 30 minutes?!

Why does this happen? When sun rays enter a vehicle, it not only heats up the air inside of your vehicle, but it also heats up your seats, your steering wheel, and that piece of chocolate you are saving for later. 🙁 As these things are heated, they radiate additional heat that gets trapped inside of your vehicle, raising the inside temperature of the vehicle significantly.

Because of this, it is CRUCIAL that you do NOT leave any child or pet inside of a vehicle on a day that is 65ºF or hotter under ANY circumstance. While the outside temperature may be comfortable, the inside of your vehicle will quickly turn into an oven and a hazard to any passengers who may not be able to easily exit the vehicle.

What if I Keep My Windows Cracked Open?

While cracking the windows may release some of the air pressure inside of your vehicle, the hottest air inside your vehicle is rising towards the roof. Unless there is a strong breeze, there is nothing pushing or pulling that hot air outside. Thus, cracking open your windows will only make a small difference in temperature.
