  • "Frunk" operation

    Maybe I'm wrong (wouldn't be the first time and I hope I am), but after seeing a few videos of the frunk closing operation, it doesn't appear to be a soft close. The rear hatch definitely is, but I'm not sure about the front. Sorry I neglected to check it out at Corvettes at Carlisle but didn't think about it until I was home.

    If it doesn't.... I really think the designers missed something here.

    Like I said.... I hope I am wrong.... because soft close is the way to go and is very cool!

    Thanks.

      I watched a couple of frunks being closed at NCM‘s 25th, and all of them were done manually.

        Thanks John.
        Wonder why they skimped on something so simple? Would be nice not to have our grimy finger prints all over the frunk.... and like Meldoon says above... doors would be nice as well.

        a friend has a Beemer with the soft door closures and they sure are sweet!

          not only did they skimp on the soft close frunk, they also didn't put a redundant latch in case the lock were to fail. Just because there is no engine in there doesn't mean I want the frunk opening up and blocking the windshield. I always assumed the secondary latch on hoods/frunks was mandatory. Another side note, the frunk is kinda hard to close and I felt like I may dent it pushing down so hard to get it to close.

            I've wondered about that, too. Prior Corvettes with hood hinged at the front didn't need a second latch, but every other car on the road with the front opening hood seems to have a double latch.

              There is a legal requirement for a second latch...

              CFR § 571.113 Standard No. 113; Hood latch system.
              S1. Purpose and scope. This standard establishes the requirement for providing a hood latch system or hood latch systems.
              S2. Application. This standard applies to passenger cars, multipurpose passenger vehicles, trucks, and buses.
              S3. Definitions. Hood means any exterior movable body panel forward of the windshield that is used to cover an engine, luggage, storage, or battery compartment.
              S4. Requirements.
              S4.1 Each hood must be provided with a hood latch system.
              S4.2 A front opening hood which, in any open position, partially or completely obstructs a driver's forward view through the windshield must be provided with a second latch position on the hood latch system or with a second hood latch system.​

                CaryBob and Tomdom.....
                Those are very interesting posts that you provided. Sounds like you had a chance to close one yourself... very interesting take.
                And that S4.2 requirement really blows me away!
                How did Chevy pull that off?

                I hope someone at GM or Corvette takes a close look at this post and makes the necessary changes before actual production starts. Doesn't sound like it would create too much of a delay, just might bring that starting MRSP to just over 60K!

                  I believe they are using a double catch system now. It has both latches built into a single mechanism (possibly requiring 2 actions to release). Some GM hood releases now have to have the handle or button activated twice to get the hood open. I am speculating on the mechanism, but I highly doubt the design team would miss a required safety feature that is called out in a standard as the design file would have all the standards/regulations listed that they must comply with. I've been in Design and QA for almost 30 years in Telecommunications, Automotive and Medical Device and the teams are pretty good with meeting regulatory and standards requirements.

                  Again just speculating...

                    Thanks SubVet.... good info and hope you are right.

                    But still can't figure out the reason why they didn't do a soft-close. They added it to the truck on the C7's a year after the '14's came out. They may have to do the same with the C8's.

                      I am not sure on that one and would be interested to learn why as well. I would imagine its a combination of cost, weight and other factors.

                        My C7 'vert has no power trunk closer. It doesn't take very much force to close, and it's really not an issue at all. I close it with the palm of my hand and get no fingerprints on it. If I've polished it up super nice and am showing it off, I'll use a handkerchief or small microfiber towel to avoid touching it with my hand. I'm not the least bit concerned about closing the frunk.

                          Don't worry, being plastic I doubt if you will dent it.
                          Might leave a few fingerprints though

                            Plastic? It’s made of “float” Sheet Molding Composite which is a fiberglass reinforced polyester with resin. Polyester is a polymer that plastic is derived from. No the hood is not plastic.

                              I knew that, but it was a lot easier to say plastic!!
