Have you ever driven a vehicle with cylinder deactivation? (just curious)

5-10% actually adds up pretty quick, and when you're on the highway cruising for a while, fuel savings are even greater than GM's estimates.

This statement confuses me:
"How much more fuel efficient would this cylinder deactivating engine be over using all four cylinders?"

Do you mean how much more fuel efficient it would be versus a non-AFM V8?

Secondly, it probably won't activate when driving around a parking lot. Check out that video floating around here somewhere with the G8's AFM engaging. Note that at lower speeds, AFM is off, and all 8 cylinders are firing to keep the thing spinning.
