I don't know how difficult this would be, but the newer Chevy V8s have cylinder deactivation, so swapping would be a big and easy gain.

Since it has 2 banks of cylinders you could also try ghetto DIY cylinder deactivation if you're brave and diligent by shutting off injectors and spoofing sensors.

If this was paired with their ultra high geared 7 speed manual this would be quite efficient - tall gearing for the highway and electric mode for acceleration around town.

Well thanks everyone for your feedback.

I'm not really in a hurry, have more vehicless than I should anyways... So I'll keep looking into this Eco-Corvette idea and let you guys know what comes out of it.

But the fact that nobody else in here is doing it is almost motivation enough...

With my Insight (a small car with a "big" engine), the trick was staying in the lower half of the tach. That, and staying off the brakes, as you say. Any acceleration that must later be turned into brake dust is a full loss.
What does the fact that a C5 or C6 is fuel injected imply in this analogy?

It was more of a side point, not entirely relevant to the original post, but I'd wager a Vette that's short shifted and otherwise kept at the bare minimum RPM will deliver fairly decent economy. With such a large engine, and with engine losses going up exponentially with RPM, I'd wager it's the primary low hanging fruit, with more to gain than aero, weight or RR.

[VIDEO] Which Corvette Generation is the Most Slippery When It Comes to Aerodynamics?
https://www.corvetteblogger.com/2021...-aerodynamics/
Quote:
Does newer always mean “more slippery?”

That’s the question asked by Mark on the YouTube channel VetonVettes757 who takes a dive into the eight generations of Corvettes to determining which generation is the most aerodynamic based on drag coefficient ratings.

Drag coefficient ratings measure the way an automobile passes through the surrounding air, and every Corvette generation has a different rating based on a number of factors including its front area, downforce, lift, vehicle weight, and more. .......

40 MPG "Ecovette" by Legit Street Cars

Found info from few years back on a 40mpg C5 corvette.

Achieving 40mph w/ basically a "Lean-Tune". Very informative video series.

Thought I would share.
