This should raise the eyebrows of a few Camaro enthusiasts. GM Authority is reporting that General Motors has filed with the "United States Patent and Trademark Office for a trademark of the "Z28" moniker. Oh, do we have your attention?

Many GM performance fans were surprised when Chevrolet did not use the Z28 nameplate for its range-topping, supercharged ZL1 Camaro. There were rumors afoot that Chevrolet may still employ the Z28 name at some point, but some of the air went out of that balloon when an option pack debuted between the SS and the ZL1 wearing the 1LE designation. And potentially furthering this speculation is an April tidbit from Camaro5, where a forum member discovered that his Camaro ZL1 diffuser bracket had the designation "Z28" on it.

Yet while many such filings are to be taken with a grain of salt (often it's just a brand looking to protect a dormant or lapsed trademark), a development like this only stokes the rumormongers' flames.

The ZL1 is, without a doubt, the top of the Camaro performance ladder, so where would a Z28 fit? GM Authority offers some speculation, suggesting that a production Z28 could "even out-muscle the ZL1." Another interesting theory they offer is that the Z28 appellation could replace the Camaro SS designation, as Chevy has the Zeta-based SS sedan range coming in next year, and GM officials could be worried about confusion in the marketplace.

When the first-generation Camaro came out in 1967, Z28 was merely the option code designation for a race-ready package (SS models were option code Z27). It was not mentioned in any literature and many customers did not know about it at first. Since then, the Z/28 has become an iconic name in the world of muscle cars.

      They need to bring back the IROC-Z

      uhh no. it will not have more muscle than the ZL1. It's common knowledge at this point that GM is developing new small block V8's. If they make the Z/28 properly, it will come with a smaller discplacement V8. I suspect they will be using the rumored 302, and give it all of the handeling bits of the ZL1, and perhaps find a way to lose another 300 lbs or so.

        There is no rumored 302, the rumored smaller displacement is 5.5L (335.6 cu), however that rumor was started because of the 5.5L displacement cap in GT2 where the Corvettes race in ALMS. Most in the know expect 5.3L and 6.2L displacements to remain for Gen V. A 5.3L (~325 close enough to 327?) high RPM screamer Gen V engine would definitely make a cool Z28 though! Unfortunately I don\'t think they will be able to trim much weight until the Camaro moves to Alpha. I doubt they will get Gen V until MY2015 or so (Gen V making debut in MY2014 in C7), and depending on how close they are to switching to 6th generation Camaro, 5th generation Camaro may never get a Gen V SBC...

      Maybe something stripped down for weight savings to go up against the Boss 302?

        The1LE tracks faster than the Boss by 2.5 sec at Gingerman. So the Boss isn't the competition.

      The original Z/28 had a 302 and competed against the Mustang Boss 302. A modern Z/28 should also compete directly against the Boss 302. It should come with a high-revving 5.0L V8. I'll put my order in now!

        Only the first gen Z/28 & Boss were this configuration. Would be cool but I doubt it.

      Camaro was released in 1967 (no 1976) and by 1968 was a official model designation in all sales literature. #corrections

        Apologies for the transposed '6' and '7' – the issue has been fixed. Thanks!

      A 1LE with the 7.0L LS7 from the Z06 would make a for a decent, legitimate Z/28 in my eyes. That's closer to what to original intent of the Z/28 was, as opposed to a beefed-up ZL1 (the SS was originally the muscle car, the Z/28 was the road racer). Bump up the handling (which the 1LE does well) and add a nice racy engine (which the LS7 does well, even if it's quite large) and I think you've got a worthy successor to the Z/28 nameplate.

        Don't forget cut the weight!
          prettycool_huh(ಠ_ಠ?
          @dan1malk
          i dunno. i dont think they even need to cut the weight if its getting the same z06 505hp. all it really needs is the ls7, magnetic ride, and there you have it the z28

          They can't really cut all that much weight out of the current platform, it's a heavyweight on its own. The real weight savings will come from the Alpha Platform.

      In the late 80's and early 90's it was always Mustang GT vs Camaro Z28. Back then you didn't have the super expensive high end models with monster horsepower. Maybe Chevy could make the Z28 a slight step up from the SS or make it a competitor to the Boss Mustang.

        that was because they were actually limited to 5 liter displacement to be race legal... the SS was the horsepower king, but the Z28 is what was raced on the track.

      Since the 1LE is lapping 2.5sec faster than the Boss,I would think its between the 1LE and the ZL1 or above the ZL1.

      Great article explaining the development of the 1967 Z/28. http://www.67z28.com/history.htm

      It's about damn time. I do hope whatever the vehicle specs and styling are honor the name and not shame it.

      5.5L made from a LS3 block with a 4.8L crank would be quite fitting for a new Z28. It's as close to a DZ302 as can be made with off the shelf parts these days excluding using an old LS2 block.

        Yeah but that config was the first Z28 only...
