[QUOTE="mc01svt, post: 15764740, member: 32337"] cylinder deactivation is one of those things that works great for reducing emissions and fuel consumption on a constant load dyno simulated drive cycle but not so much in the real world. A v8 running on 4 cylinders is an instant reduction of 50% working volume (displacement), however real world fuel savings if any is around 5-10% tops. its yet another technological gimmick that increases cost, complexity and has higher occurrences of failure with little benefit to the consumer. for a quick sanity check look at the mpg ratings for the f150 5.0L vs the silverado 5.3L. The 5.3L has cylinder deactivation, the 5.0L does not and they have virtually identical ratings. The trucks are both bricks, similar curb weights and drive ratios. [/QUOTE]
