Yeah, it's not great. Luckily it's the base trims I guess. Maybe that's on purpose to up-sell

This, even the top level trims are worse than before

Less than an hour to go for the Z06 reveal.

Well holy sh!t - I did NOT expect 670hp from an NA 5.5l
Great job by all those at the Corvette team.

I knew it would be DOHC, and FPC, but 8600 is a surprise (I guessed similar to Voodoo at 8250), and the HP is way more than I expected. Torque is as I thought, but that's how FPC engines always are.

So they managed to build a 15yr old Ferrari, for the cost of... a 15yr old Ferrari. *golfclap*
I just cant get excited about GM doing something thats already been done, just at a lower price point that is still far to expensive for me. |

This is what happens when you build a FPC correctly. Now, I like Voodoo, but Ford not going with a dual intake and throttle body setup was a huge mistake.

https://www.motortrend.com/news/2023...ankshaft-tech/ "Resonance Supercharging (Free Boost!) In a flat-plane-crankshaft V-8, the firing order always swaps from one bank to the other, lacking the syncopation cross-plane engines get from successive firing on a single bank (that's what makes them burble). The real intake-manifold magic that leverages this potential volumetric efficiency windfall is a series of three valves connecting the two intake plenums that open in different combinations to vary the degree to which pressure waves communicate within or between the LT6 engine's plenums. When each of the Corvette Z06's 32 individual intake valves slams shut, it creates a pressure wave that reflects back up the intake runner. When the timing's just right, that wave reflects back down a runner while its intake valve is open to help cram extra air in. This is called resonance supercharging, and it's based on the same Helmholtz resonance effect that creates sound when you blow across the top of a bottle. This type of supercharging exacts no horsepower penalty on the engine. The three intake-plenum valves all start out closed. Then as revs rise, one opens at around 2,000 rpm, then all three open for a short time around 5,800 rpm, after which they all close again. (That's the strategy in Sport and Track modes—different strategies are employed in the Stealth and Tour modes to optimize for quiet running.) This allows the LT6 engine to achieve a volumetric efficiency rating of greater than 100, meaning it can naturally inhale a volume of air greater than the static size of its cylinders. This is rare in naturally aspirated road-legal production engines." Here is some crankshaft info as well: https://www.motortrend.com/news/2023...ankshaft-tech/

I do enjoy reading comments that essentially read "yeah, well, not as good as a 500k Lamborghini"
