camaro z 28 still in the works aims to top hellcat hp report

If you’re worried the Car and Driver, Camaro chief engineer Al Oppenheiser claims the hottest variant of Chevy’s pony car is slowly growing legs in the GM stable. When will it drop? That’s classified, sorry.

The big question, which as of yet remains unanswered, is, “what lives under the hood?”

Two options exist. First, GM could massage the existing supercharged LT4 6.2-liter V8, boosting output to about 700 horsepower. That’s a tempting option for the automaker, but not necessarily ambitious.

It’s also possible the Z/28 will become home for a new GM engine family member now in development — one that does away with pushrods in favor of a dual overhead cam setup. The motors, rumored to carry LT6 and LT7 designations, would be 32-valve, all-aluminum V8s and could potentially be GM’s most powerful naturally aspirated and turbocharged, respectively, engines to date.

There’s solid reason to believe the upcoming C8 Corvette will carry a Shelby GT500 Mustang variant in the coming year, and topping the Hellcat’s horsepower seems to be Job One.

    I thought the Z/28 was supposed to be a GT350 competitor with a NA big bore V8 (7.0L? LT7!!!!!!) and less HP than the ZL1?

      Doesn't have to be a large engine, but it does have to compete with the 350R. For fun here is John Lingenfelter's (RIP) flat plane crank LS motor. 621bhp @ 9000rpm. Less than 6 liters of displacement. I wonder if anyone got him to put one of these in their vette?

    The Camaro is trying to out-horsepower the Hellcat. Why?!? Are there that many small-penised men in this country? Dear automakers - grow up!

      As opposed to what? These are hero cars for the brand, rolling billboards meant to demonstrate the capability of the manufacturer and to provide the fans with something to cheer for. Comparatively few will be sold but it will keep people talking (well bench racing as they compare 'ring times and 1/4 mile runs and shoot outs) about the cars Generally its a win/win for every party involved. The manufacturers, the dealers, and brand loyalist as well as sites like this.

  • Bill Wade Norm, while true I'll leave you with this. My 2023 RAM is running Android 8 released in 2017.My wife's navigation on her GM truck is a 2021 release, I believe the latest. Android Auto seems to update very week or two. Now, which would you rather have? Anybody with a car a couple of years old NEVER sees any updates. Heck, if your TV is a few years old it's dead on updates. At least cell phones are rapidly updated. If your old phone won't update, buy another $200 phone. If your GM vehicle doesn't update do what, buy another $50,000 GM vehicle?
  • Lou_BC Once again, Mustang is the last pony car standing. Camaro RIP, Challenger RIP.
