What is missing on current cars with cylinder deactivation is the ability to lock it in and then add more throttle to put the motor in a more efficient throttle/rpm as soon as you add just a little throttle the computer kicks you out of cylinder deactivation.
The 2015 Chevy trucks now have direct injection and cylinder deactivation. I am interested in how well they might do in real world but would also like to see new engines built from the ground up with this in mind rather then add-ons to old motors which is what Chevy has done.
My friend Kyle has the 2015 Silverado with cyclinder deactivation. He says that he consistently gets 28mpg highway when he's trying to stay in cyclinder deactivation mode.
