The new idea of running on only four cyl out of 8 in cruise mode for about 3 mpg additional may become a standard in the future. Of course there is no easy way to retrofit this idea with a computer control because the valves are closed in the Dodge arrangement on the four cyl not used, so even if you convert to fuel injection and turn off four injectors you also need to close the valves to the four cyl not in use. Then assuming you can swap in the whole engine, you need the Dodge computer. Still some rodders should start messing with the new hemi as far as swapping it along with whatever computer controls are needed to make this feature work because it looks like a neat way to have it both ways, a V8-hemi when needed and a V4-hemi once you get into cruise mode. It is extrememly unlikely there is any cost effective way to make this swap for an old Suburban (although technically you can swap anything into anything) but hopefully some rodder group will do the work to make this swap possible in the near future along with the V4/8 mechanism.
