The difference between this system and the current one your friend has that the new system can deactivate any cylinder at any time depending on load requirements rather than just four cylinders.
I didn't understand some of the article, but I think this is a pretty good idea. The problems that I have seen with this cylinder deactivation is that dropping 4 cylinders leads to that clunky feeling and odd sound. Having the ability to just drop 2 cylinders, apparently in random order, should work pretty well in a heavier truck. I'm curious to see how this technology works int he real world. 15% increase in fuel economy (maybe 3 mpgs) might be worthwhile... depending upon the cost and complex nature of the engine. Hope they maintain reliability at the same time.
