GM is poised to revamp the Chevrolet Silverado and GMC Sierra models by replacing the current cylinder deactivation systems with a budding new innovation called Dynamic Skip Fire (DSF) technology. According to GM, DSF can boost fuel efficiency by 21%, as seen when testing out this feature on a GMC Yukon Denali model.

Bagging rights go to Delphi and Tula Technology for coining the technology in the first place. GM has allied with Tula Technology in the past, so it is no surprise that it is pairing with both entities to introduce this new feature in the 2019 Chevy Silverado and 2019 GMC Sierra.

DSF works by cutting off two cylinders of a V6 when not in use; similarly, it cuts off four cylinders of a V8 engine. Besides reducing energy consumption, Delphi and Tula Technology have both been researching for ways provide vehicles with alternative energy.

To this end, Delphi designers have expanded the technology to incorporate a 48-volt plug-in hybrid system that would provide an earth-friendly energy reserve. Both DSF technology and the nascent hybrid system promise a potentially potent solution that manufacturers could turn to in the near future.

As Dave Sullivan, analyst with AutoPacific, puts it, “Combining these two technologies sounds like the methadone Europe needs to get off its diesel addiction.” With the current instability of the diesel fuel situation, such innovative new technologies are welcome.

Manufacturers like GM can expect to pay an estimated $350 for the new DSF feature. Technology that reduces the carbon footprint and promotes eco-friendly fuel is a long-term investment—not just in the health of Mother Earth, but also in the future sustainability of the auto industry in light of a potential decline in diesel.
