The engineers always talk-up a new engine well but this exposition sounded good.
I'd love to know more about the sliding components of the camshafts. It's cool both varying lift and cylinder deactivation are accomplished.
Does the "hammering effect", provided by the "dual valute" exhaust routing, occur at both sides of the driven wheel (say, 180 degrees apart)?
Any video needs to lose the "6 o'clock news chatter" angle. "Oh, this is where we put our gloves on", sounds so dopey.
Let's just hope this isn't another Vega engine.
CUSTOMER: My engine doesn't work!
GM: Oh yeah, we had block warpage probs we didn't anticipate. Sorry....bye. Just buy another GM product".
