During the fall and winter Maybe but in a Normal August in Mid-Atlantic and lower Outside temperatures can get up to 100-105º or hotter. Now couple that with the trunk of a say a Black Car, your talking about upward of 135-150º. I imagine unless the camera is put in sealed bag surround by ice in a Cooler, the camera electronics would be toast in about 15 minutes to 1/2 hour. Plus most modern camera now are either made with or covered with some forms of Plastic. And while temps may not be high enough completely melt the plastic, could soften it enough to deform it. I would not recommend it. And would The front or back seat be any better. No. Because with a combination hot paint and all the window glass acting like a heat magnify, unless window left open could get even higher.
I wouldn't recommend keeping any modern camera in a Hot car, Van or truck for any length of time. And if in front or Back seat without the windows down for any length of time. Although this Summer has been unusually cold with some 70º degree days and 58º nights in July and August. There have been some days when I got in our Tan colored Impala and for a few seconds until the Air Conditioner came on I could feel my lungs burning from the inside.
This is what I have done for many years: Place the camera in a ziplock bag, thoroughly dampen a bath towel and cover the bagged camera. As the water in the towel evaporates it keeps the camera cool. This has worked for my film and digital cameras up to +100 degree temperatures from the Carolinas, Florida and all across the western US.

The website I linked to above says it is OK to put in an insulated bag inside a cooler. I'm getting an insulated bag and will measure the temperature. Perhaps I won't be able to do it in the summer.
The idea is to leave my old D40 with the 18-55 in my car so I'll have one available. Ask my family how many times I've said "I wish I had my camera"!
My daughter spent most of July with her grandparents and took a lot of photos. At first she was using her telephone, but I think she finally realized how bad they are. Then she took over my wife's compact camera, which is more acceptable. I thought she might be interested in having my old D40, but not at this point. So that's why I think I'll try to keep it in my car.

After the glove compartment, the trunk of a car is the hottest place in a vehicle. When I know I want to leave a camera in my car, I use a foam cooler in the floor of the back seats area, covered with a towel or cloth of the same color of the upholstery, to avoid calling too much attention when parked.
According to tests reported on the link I gave, the trunk is about 10F cooler than inside. This agrees with what I've heard before. A greenhouse effect is caused inside the car because light comes in through the glass, but the infrared re-radiated can't get out as well, so it gets hotter.
Yikes, NO! In fact the user manual specifically mentiones avoiding heat; ditto for nearly all electronics. And if anyone breaks into your car and your car trunk you are out of luck. Never leave anything valuable, or that you can't afford to replace, locked in a car. It might as well be out in the open.
If you took a cooler and placed a thermometer with the minimum/maximum feature you could leave it a day and see the maximum reading. If the reading was high you could try the cool towel or leaving a frozen water bottle in it.
I would never place a frozen water bottle in a cooler together with a DSLR or any other electronic devise for that matter. The likelyhood of water damege due to condensation or leakage is just too great.
No matter the insulating aerial used over time the inside equilibrates to the outside temps, the insulating device used will determine how long that takes so if you left it in all the time after a day or two of hot weather you might as well leave it out of the cooler. Also once it equilibrates even if outside temps drop you have the same scenario. Inside the cooler will take as long as the insulating material allows to cool back off.
Instead find the thermal blanket material instrument owners use around their acoustic instruments. Keep it in a small camera bag and when you leave take ti to the car when you get home bring it in. I do this daily. I found at first I would forget to take it with me so I started leaving my keys with the bag in the house or leaving the bag by the keys, now it is second nature to bring my camera gear whenever I go.
I will also use a remote starter to cool the car off mid afternoon.

Coloradocase.com is the company the musicians will use for thermal protective cases. I could not find the material but an email to them just might answer some of your thermal material questions.
Conversely you could just try one of the space blankets, role an electronic thermometer up in it and see how high it gets in your car. If it works well you could modify it and insulate a small bag with it.

The answer you're looking for is 122 F, with a battery installed. It's right in the manual. Without a battery installed, they're shipped in containers across the Pacific and experience temperatures in excess of 170 degrees with no ill effects - indeed, under heavy shooting, the interior of the camera can reach up to about 180 degrees without ill effects to any of the parts.
The plastic is PC, the screen is glass, the boards are glass and metal, and so on. There ARE issues when power is applied and they start generating their own heat, and you can get electron leakage, which is why you shouldn't power it up until it's been cooled down.
However, if you allow it to cool before installing the battery, you don't have that issue. Also, with the D40's batteries, ensure that it's stored with a plastic cap on them so you avoid short circuits.
Also, it's a D40, so even if it does get hurt, it's not like the body owes you anything.

I threw the plastic caps away.

Yes, it is my old D40 with an 18-55, so I won't be heartbroken if something happens to it. Just about a week ago I missed a shot of a light pillar because I didn't have a camera. Since then I've had the D40 in my car.
And I did some experiments. Since it is cooler now, it doesn't get hot in the trunk, even if it is in the sun (well, low-90s F). I got one of those insulated bags. I took two identical thermometers and put one in the bag (in the trunk) and one just in the trunk. Temps were in the low 90s in the trunk, with a degree difference.
To get a better test, I put them inside the car, out of direct sunlight, but let the greenhouse effect heat up the car. The one outside the bag reached 105F but the one in the bag was 87F at that time. Later in the day, the inside had cooled off to 94 and the one in the bag was 92, but in the hotest part of the day the bag kept it 18F cooler.
Of course, I will have to test again in a few months when it gets hotter.
I would expect the trunk to be significantly cooler than the cabin. If you have a Styrofoam cooler put your camera bag in there. If there are closed water bottles or other thermal mass in there, so much the better. Just no direct exposure to moisture. An empty ice chest works fine. That should delay heating by many many hours. I've never had a problem doing this. A warm sensor will be noisier, however.
I've had my spare DSLR in the trunk for quite a while, but, of course, it hasn't been hot since I put it there. I bought a Coleman insulated cooler bag, and that is the "bag" for the body and one lens. In the spring I'll check the temperature inside the bag to see how hot it is getting.
And I'm not really worried about noise, because this is so that I will have a camera with me when I'm out driving and see something I want to photograph.
I have a friend who kept a camera in the trunk wrapped in a blanket--had to buy a new camera.
I have another friend who got a good quality cooler and some big gel packs. Every day another gel pack was put in the cooler . The camera itself was kept in a waterproof wrapping to prevent moisture from forming around the camera. This set-up was rather elaborate but enabled them to carry the camera in the trunk. If you don't want to do these elaborate precautions, I would just get a small camera that I could carry in a pocket, or a cell phone that has a decent camera.
