Well like I said, I'm willing to withhold judgment until we know final performance specs (or hell, even final hp numbers, since this 465 number is still far from confirmed from what I gather), but that number is still somewhat disappointing. CAFE standards or not, with all the tech they're packing in this new gen, I would expect that they could squeeze out more than just an 8% gain.

We should all take those curves with a grain of salt. When data is plotted on the same graph, the torque and horsepower curves for two engines should ALWAYS cross at EXACTLY the same rpm. They do not on this graph, so the graph is bogus.

Oh, I'm sure they are. I just think they are going to wait a few years to give it all to us

DI and higher compression are two of the few win-win improvements you can make to an engine that improve both power output and economy significantly. Then you toss in other new fuel saving tricks like AFM, and I wouldn't think it would be hard to get mileage that would be acceptable on a car like the Corvette, which won't exactly sell in HUGE volumes.
