Looks like greencarcongress has a comparison of fixed cylinder deactivation versus rolling deactivation on Fords 1 liter triple. NVH, complexity and cost balanced in the comparison. Looks like fixed is winning out in the cost and complexity without loosing too much gains in mpg. I'm not a fan of using dual mass flywheels because they fail often and at great cost in the used car market. They use them to help overcome the shakes.

Mirror deletes, 80% grill blocks, wheel covers, 50 psi tires = 6% better MPG avg. over a year. Wheel skirts overcoming ethanol winter fuel mpg losses and more!
