  • C8 Rear Hatch Venting System Patent

    Here is a detail that is very interesting. A couple of us had heard of something like this a couple of month ago on the condition it not be shared, but noW that Road and Track has fully outed it, here it is, with one additional note that the little birdie who told us that info shared that “it looks really special when you are standing next to it.”Thanks and credit to Road and Track.

    The Mid-Engine Corvette's Hatch Has a Unique Design to Aid Cooling

    Chevrolet's patent application for the new supercar's engine cover is worth analyzing.

    R&T

    Most spy shots of the upcoming mid-engined Corvette show a mesh cover over the center of the rear hatch. Now, a recently uncovered GM patent application might explain why. Titled “Venting Module for Vehicle Compartment Cover Assembly,” it shows a center piece for the rear hatch of a vehicle that is described as “vented engine hood assemblies for motor vehicles with a rear-engine or a mid-engine layout.“

    The hatch cover is described as a glass module surrounded by a carrier frame that is perforated to allow the engine to vent. This would explain why the prototypes we’ve seen have had a mesh cover over that area or even left it completely open: so the engine wouldn't overheat.

    The application explains that that this hatch cover–described as an engine hood–can combine a back glass panel with a supportive frame that can enable improved radiative and convective cooling of the engine bay. It states that in some configurations, the venting assembly could be composed of magnesium mesh. The current generation Corvette employs magnesium for strength and weight savings, so it's not surprising that Chevy would use it on the next generation car.

    According to the operational description of the hatch, the design described in the patent can provide more than a 200 percent increase in venting over some traditional designs. It also states that there are other advantages to it, such as the ability to eliminate the bridge structure used in other glass rear hatches which reduces weight and aids in manufacturing.

    PATENT IMAGE

    Included drawings and diagrams show a mid-engined vehicle but it is only used to show the location of the hatch for the purpose of this patent application. The drawing of the actual hatch itself is likely similar to what we could see in a production version of the car.

    PATENT IMAGE

    A gap exists at the top of the hatch in the drawing, but if we look at the spy shots, we can see that this is the spot where what appears to be a camera module is mounted. A similar gap exists at the bottom and the triangular shape might point to the location where a Corvette badge might be placed.


    It now seems less and less like a question of 'if' we'll get a mid-engine Corvette, but when we'll see the mid-engine Corvette.

    So many questions about the ME right now; so few answers yet.

    Was about to post this myself! Great stuff John.

    Gee, that drawing in the patent looks an awful lot like a 488...

      I love engineering. They take brains of a kind in a different wheelhouse than mine. I will truly will mentally be dissecting the mechanical and technical advancements of the C8 over and over, and look forward to our discussions of them here.

          ... and it has ROUND taillights ? !

          Could the Mules we've seen, are covered to appear square, to throw everyone off??

          Yeah I know it's a stretch, just wishful thinking.

            ^^^ Nah, the tail lights are meaningless. They're just placeholders on a patent app the substance of which has nothing to do with them - the sketch of the car is illustrative regarding the rear glass/venting system location/shape etc which is the subject.

            Nice grab, John. Good stuff.

              Well that explains the temporary rear "vented hatch" on the nurburgring cars. cool find!

                Guess venting a motor in the rear is a good clue to us learners that there is going to be a mid-engine Corvette after all.

                  those are the real deal in the ring photos.

                  note the hex "mesh" in the openings.

                  Tho the VERT hatch does have a hidden or temp hatch cover. IMO

                    Hmmmmm. I think the description is missing the part that makes this patentable. It has to be more than vents on an engine cover shureley?

                    Here's Hoovies "new" McLaren.

                      Thanks fvs, I had never “expanded” the picture and seen the mesh before.

                        That R&T description also makes no sense. Where have they been? (not reading MECF obviously). We saw this exact hatch months ago. On the fastback coupes. The "mesh in the center" versions were the convertibles.

                            somebody needs to photoshop a big decepticon symbol in the middle of the glass part, because that's what i'll put there.
                            I'll be selling a part of my TF collection for a juicy down payment on mine.

                              This is a very interesting patent. Most of all, it needs to work well to vent the motor’s heat.
