Wayne,
A crank disconnect will not...I repeat WILL NOT work. (err, it would require separate cams all its own timed with it...the catch wouldnt be in the correct spot every time). The problem with GM's VCM (that the variable volume right?) is that it only shuts down the valves of the pistons. This is compressing and expanding static air for every rev...plus its dragging copper around on the piston walls. In addition...hypermilers would have to heat the cylinders back up when they needed the power. I was thinking on my commute today (oooo, look at my last tank
) that the atkinized V-TEC would require a variable intake manifold...but thats pretty simple.
Cheers,
Steven
Oh, I was also thinking...why the heck are milage machines not using boxter engines?!? The way they balance themselves out kills the need for the extra weights on the crank...less spinning weight....same as reducing the weight of wheels.
