Just to clarify:
Speaking of, the 2020 Stingray makes 490 horsepower – 495 hp with the optional Z51 Performance Package – which is a considerable jump over the 460-hp LT1. There is some disappointing news for row-your-own enthusiasts, however. That power is handled exclusively by a new eight-speed dual-clutch automatic, though you can still swap cogs at will with paddle shifters behind the steering wheel. And yes, it still goes exclusively to the rear wheels. What does this mean for performance? Actually, it’s pretty darned impressive. When equipped with the aforementioned package, Chevrolet says the new Stingray can rip to 60 mph in less than three seconds."

As speculated, the Stingray is fitted with a 6.2-liter V8 derived from the LT1 used in the current car. It's called the LT2 and actually, it's quite a different animal. With the Z51 Performance Package the engine develops 495 naturally-aspirated horsepower, and it sends that power to the rear wheels exclusively through an eight-speed dual-clutch automatic. Sorry manual fans, but you can still control cog swaps by hand through paddle shifters on the C8's steering wheel.

Looks like the 495 hp Z51 performance package is the one doing 0-60 in under 3. I have no problem admitting I'm wrong if someone can show me where the two articles I quote above got it wrong.
