It tanked. I guess the theory was good, but tech wasn't up to the job  
yet, so the motor ran poorly on 4 and 6, had little or no power at  
that range, and then was still a gas hog (which is what the 4-6-8  
design was trying to solve)

All new Chrysler Hemis run on a similiar "displacement on demand"  
design, 4 cylinder cruising with v8 power. They average 20mpg.
