Although the air won't reach 80C in a car, objects in it could ( 80 degrees Celsius is 175 degrees Fahrenheit):
According to the National Weather Service, the atmosphere within the car is "
warmed little" compared to that of the objects within the car. A dark dashboard or a seat, for example, "can easily reach temperatures in the range of 180 to more than 200 degrees Fahrenheit," the agency says.
"These objects (e.g., dashboard, steering wheel, childseat) heat the adjacent air by conduction and convection and also give off longwave radiation (red) which is very efficient at warming the air trapped inside a vehicle," the agency added.
In Phoenix, which has seen weeks on end with triple-digit temperatures, Dr. Kevin Foster of the Arizona Burn Center told
NPR that seat belt buckles can also get so hot that they lead to burns.
"The interior of an automobile, particularly one with dark upholstery, can get to be 160 or 170 degrees," Foster said. "The worst thing to do is to touch something that's metal inside the car that's been exposed to direct sunlight like a seat belt buckle."

Artificial Intelligence blurb that raw carbon fiber is very heat resistant but composites less so:
While raw carbon fiber is highly heat-resistant, carbon fiber composites are more vulnerable to degradation from heat due to the resin matrix. Understanding the specific properties of the composite material and its intended application is crucial for determining its suitability for use in different temperature conditions.
