Hagerty Leaks GM’s Alleged C8 Engine Roadmap!

If this C8 engine information is accurate, the Corvette is going to dominate the roaring ’20s.

Hagerty this week leaked an alleged roadmap for all future C8 trims and engine configurations. In the context of their reporting, “GM’s executive director in charge of program management, Michelle Braun, recently issued a blanket order pausing all future car and truck development—including for the Corvette.” In other words, even if the following information is all 100% correct, this timeline could very well be pushed back a model-year or two as GM and the world economy recovers from the current pandemic slowdown.

Still, it’s promising news that seems to follow earlier leaks as well as spy videos and spy shots. Or it could be all garbage.

Most interesting about Hagerty’s figures? The editorial change made after first publishing the figures. The Z06 asterisk was added after “credible industry feedback suggested reduction in output compared to [their] original estimates.” Hagerty initially reported the Z06 would have 650hp, but they since dropped that figure to 600hp. Which makes me question everything else, to be honest.

First, let’s chat Z06. Yes, it’s a bit of a branding bummer if the C8 Z06 offers fewer ponies than the C7 Z06. But returning to a naturally aspirated setup fits with the Z06’s legacy and the current C8.R. But, how in the hell does GM market a Grand Sportand a Z06 that offer the same horsepower specs? And, assuming the Grand Sport actually includes hybrid drivetrain components (a definite possibility), how does GM sell a Grand Sport with more torque than the Z06?

That seems impossible, given the history of each trim level.

What should we conclude, you’re asking? We could only speculate, but something above isn’t right.

As for the ZR1 and ZORA, both figures and configurations fit with everything rumored so far, although what a shame that we’ll have to wait three, four, or five years to learn the truth. Regardless, we have sky-high expectations for the C8 generation, and, by the middle part of this decade, GM appears ready to meet and exceed those expectations. The C8 has always competed with far more expensive sports cars, but now seems poised to become an honest-to-goodness supercar. And maybe even a hypercar.

We live in incredible times, friends.
