No. It would go cold overnight with the engine.
It only damps sound, its not there to keep the engine warm.

That is there to help the engine from getting to cold over night , i dont mean cold as in arrr porr thing but when its -2c etc it will help keep the cold out from the under skin of the bonnet , it will all so help the engine heat up quicker in a colder time as well , all so it will protect your paint work as that extream heat on the under skin could over the years fade or damge the paint , and it all so will make the engine sound that bit more quite.
what ever you do DO NOT put on the mirror things under your bonnet , it will cook your engine mate , i know this as it has happed to 2 peope i know of !!!!

My LX didnt have any.... ever. How come the paint on the turrets survives?
Mirror doesnt reflect heat, only light.
Now if your engine is glowing, you may have a small problem. Id suggest a new thermostat.

I think you'll find Mirror does reflect heat, thats how a thermos flask works, and some people have silver foil behind there central heating radiators, to reflect the heat back into the room.

A thermos works by keeping a vacuum between the liquid and the rest of the world. Vacuums dont pass heat. Therefore the liquid retains its heat.
The only way a mirror would reflect heat is to be hard (dense) - A piece of hardwood will reflect more heat than balsa wood because it is denser. And as the bonnet is made of steel, its pretty dense already. A piece of film wont make any difference.
The foamy layer under the bonnet wont even help during warm up, because (with any luck) there will be moving air in the engine bay which is there to cool the radiator. The moving air will insulate the foam from the engine.

If vacums don't pass heat, we would all be dead, and the world would be covered in snow and ice, the heat from the sun travels through space, which is a vacum, and heats the planet up. Those old electric fires used to have a mirrored curved back on them to reflect the heat into the room. Having said that, have a look at this,

It sugests heat doesn't travel through vacum, so I don't know why we are not all frozen, but it does say mirror does reflect heat, I think a thermos flask was a bad example to use.

The earth is warmed by the light which travels through the vacuum of space, not heat. This is why its cold in winter (less sunshine due to tilt of the earth and all that.......).
You may also notice that old electric fires glow red - the mirror is there to reflect that particular wavelength of energy (which happens to be visible). Is the inside of your oven mirrored? No.

You beat me with your reply, after a bit of research, I realise I may be out of my depth a bit hear, I was quoting facts I thought I knew from school, many years ago. It looks like you could be right, Its all about wavelenghts and types of energy, all a bit beyond me,lol, I bow to your superior knowledge. Have you noticed how they spell vacum, VACUUM

My Mondeo was an LX - it didnt have any.
But my brothers was a GLX which did. His car was always quieter than mine (until the bonnet was opened)

The light itself has no heating effect, its the infared radiation given out by the sun that warms the air, this is a similar type of electrmagnetic radiation as light but is a different wave length and also invisible. Thats why mirrors are used round electric fires and radiators to reflect this back out to the room rather than the wall.
