Is the cockpit separated from engine compartment

[AirdaleC7]

Curious how the cockpit environment is separated from the engine compartment. I haven't seen any mention of how this is done, but figure it must be to keep the heat and noise under control. Has anyone seen how this is accomplished?

Based on what I've seen in the pictures so far, there's a glass partition as well as firewall in place to separate the pilot cabin from the engine bay. In one of Chevrolet's videos, they explained that the intent is for the driver to hear only the exhaust and the intake sounds from the engine, therefore special attention was made to how they were to separate the engine bay from the cabin.

Due to Federal law there has to be a divider to protect people from
engine fire, smoke, fluids, fumes, exhaust, noise, engine bay high temps and most of all protect people from rear end crashes from engine moving forward
so there is a frame/bulkhead right behind the seats for those reasons

There's a firewall / bulkhead with a 9mm thick window in it. There are photos in several threads.

I figured as much, but since no one had mentioned the subject I felt I'd better ask. Like many of you all, I'm going to be faced with ordering a car that I not seen, sat in or let alone driven -- so I need as much detail as I can get before I sign in about three-weeks time.

It’s appears to be a slightly thicker piece of acoustic glass. I remember Tadge saying that they wanted to isolate allot of the engine noise from the cabin. I kinda wish there was a way to port some of that glorious sound into the cabin when you want to hear it! Here are a couple photos I took from the Bridgewater NJ Reveal.

Try and visit one of the dealership displays of the C8! https://www.midenginecorvetteforum.c...tour-locations

I remember reading somewhere that they do have a sound-tube type of thing to pipe in certain frequencies from engine compartment to the cockpit. Also, the audio system has noise cancellation to reduce apparent sound from other sources. Primarily tire noise I assume.

The acoustical glass is more than 1/3” thick to keep out all the above uglies.

This car will be quieter with less heat in the cabin than most FE sports cars. Had a viper in 06 and that car was awful when it came to noise and heat in the cabin, lasted two months.

I know this is such simple logic but most don't think about it, don't blast me.
95% of the time you are driving forward while the car is running. In a ME the engine and exhaust are behind you and the heat never crosses the driver since you sit in front of the engine. In a FE you have a big hot engine and exhaust in front of you, while moving forward that hot air has to pass by the cabin of the car, this is not the case for a ME. It's always behind you and the air is pushing away from you, unless at a stop.

Making the rear glass thicker probably helps with unwanted noise and possibly safty.

This is still a good topic since none of us have actually driven the car. Have any of the folks driving C8s on the tours and shows said anything about cabin noise or heat? Any reports on this topic?

Yes, I had read that as well. The sound tube funnels the more desirable engine noises into the cabin while the less desirable pulley and belt noises are insulated from the driver with the plexiglass.

Here is the quote from the article reference the divider and sound tubes

"An unfortunate aspect of the mid-engine placement is that the V-8’s accessory drive is located directly behind the passenger bulkhead. Corvette engineers prescribed a 9mm-thick window between the cabin and the engine compartment to filter out the undesirable noise and added a composite-material sound tube that routes appealing exhaust noise from the back of the engine into the cabin."

My Ferrari F430 is quiet until you open it up. But I am running aftermarket headers too along with the factory exhaust valves. Dont know the back glass thickness but no heat at all coming from the rear. My vipers I had before though with frt engine config and exhaust routing was hotter than hell!

Driving a C8 with a mid-engine V8 motor will come as a surprise to most Corvette owners. Despite the firewall and soundproofing, the V8 motor is in the passenger space with you, you are very aware of it, it is a constant thrill.
