I have a 2022 HTC. Last month I drove on a trip that was over 3 1/2 hrs straight. Got home and removed my suitcase with clothes and dopp kit immediately and tossed my clothes in the laundry. Everything was completely the same as if it was in the trunk of my BMW. Absolutely none of it was warmer than room temperature.

I think it was the Car & Driver test where they were complaining about the hot trunk on the C8 seeing that it is next to the engine and above the exhaust. How bad is it? How hot does it get? I'm surprised the corvette engineers couldn't find a way to get an A/C duct to it. Any solutions?
TKOPerforamce has a heat shield they say will cut the heat rise by 30 degrees.
installed in my Coupe and my temp rise tends to stay under 30 degrees; using a TempStix to measure heat rise

Did you put the pizza in standing on end? That would make a calzone with sauce
Wait I forget the rest of the world doesnt have real pizza like NY- Probably one of those gluten free non gmo vegan personal pies might fit- but who would want to eat it

Trunk temps aren't really a problem while you're moving. It's when you park, and the trunk gets heat soaked from the engine and exhaust. Trunk insulation will only slow heat transfer into the trunk, it won't eliminate it.

I have the fitted luggage for the C8 and I think as long as you have good leather bags, you don't have to worry that your stick deodorant is going be a melted mess after a road trip, though it doesn't hurt to keep toiletries in the frunk as opposed the trunk.

I would say it's quite warm. Took my new C8 to the golf course this past week. About a 45 minute drive. I keep a bottle of whisky in my bag for birdie celebrations. Birdied number 2 and the high temp ruined my drink.

You can remove the cover to access the air filter and place a heat shield on the inside of it. I put a reflective barrier, but it only helped a little. I’d recommend a thin insulation pad with a reflective barrier on it.
The trunk isn’t extremely hot, but I wouldn’t keep the milk or ice cream back there.

I experimented with a thermal barrier, but it did not do much. I ended up pulling it out. See the following thread for my results and speculations based on those results.

i've found by using a TempStix to monitor trunk heat that once installed it limits trunk temperature increase to sbout 30 degrees over the outside temp. A reduction of about 30 degrees from what it would hit
HTC is an easy install. Couple requires the removal of the storage brackets so takes a little longer

Here’s a great interview with Tadge wherein he acknowledges around the 2:15 mark that airflow and thermal were the biggest challenge in engineering the C8 since they wanted room for luggage and the roof in the back. After watching this I’m grateful that the C8 has a trunk at all and I will quit complaining that it gets a little hot especially since it has a frunk too.

i installed some Thero-tec (
) and I also keep a soft sided cooler in the trunk for those unexpected trips to the grocery store on the way home from (insert location). It's worked out well and I have no complaints.

You can (and should) either order through your dealership or using the MyChevy app. Be forewarned that these bags are pricey, about $700 a piece, but are quality. Two bags fit in the rear trunk and one in the front trunk. You only really need two for the rear trunk.

This made my trunk very close to the normal temp of a normal trunk. This material is like the bubbled windshield sun protectors.

I bought from Amazon one roll of Brand: US Energy Products Double Bubble Reflective Foil Insulation (24 inch X 10 Ft Roll). Cut roll into two 10ft pieces. Then ,when I changed the engine air filter I installed one layer along the front part of trunk and along the base of trunk. Then I tapped the second piece about half way down the front of the trunk. Making two layers on half the front of trunk and bottom. Cut 3 inch holes for reattaching the cargo net hangers that hold the trunk liner in place.
This made my trunk very close to the normal temp of a normal trunk. This material is like the bubbled windshield sun protectors.

We stored a bottle of red wine in the trunk on a 3 hour trip, got to destination and the cork was half way out because of the heat. Now we store in the frunk. Always something new to learn in life.LOL
