Dynamic Skip Fire, new tech that should work with most any gasoline engine, boosting fuel efficiency by up to 15 percent

Clever new cylinder control gives big MPG boost—and it’s ready to roll
Delphi and Tula have taken cylinder deactivation to the next level.

The gasoline internal combustion engine has been in service for well over a century at this point. After all that time, you would think we would have perfected it by now. It's as simple as suck-squeeze-bang-blow, right? But recently we've seen a number of new technological advances that each offer significant gains to efficiency—probably a good thing considering how long it is going to take to move to an all-electric light vehicle fleet.

[The latest one I'm enthusiastic about was cooked up by Delphi and Tula. Called Dynamic Skip Fire, the new tech should work with most any gasoline engine, boosting fuel efficiency by up to 15 percent.

Cylinder deactivation ain't new

Just surprised they still haven't gotten the bugs out of it yet and gotten further.
Because these paper theories work in controlled environments with computer systems managing throttle and braking.
In real environments throttling is not perfect, system is not perfect and doesn't work as well .
