Yeah, an LS3 motor displaces more than an S65. But the LS3 weighs less (415lbs vs 445lbs).

So the LS3 is a lower-weight engine, with fewer moving parts, more HP, more torque, and better fuel economy.

And before somebody says something about antiquated pushrod designs, just remember that overhead cam designs pre-date pushrod designs by several decades.

Anyway that's the former vette owner in me coming out... I do love the S65 sound at 8000rpm. And I love BMW straight sixes (particularly the diesel!)
That's an interesting - no startling - little known fact. Go Corvette; go GM; go USA!
