General Motors’ trucks — including the Chevrolet Silverado 1500 and GMC Sierra 1500 — are already known for being near the head of the class when it comes to fuel economy, especially in a segment where decent fuel economy can be difficult to achieve. But according to an announcement from earlier this year, we can expect even greater efficiency from the 2019 Silverado and 2019 Sierra models, thanks to updated fuel-saving cylinder deactivation.
The technology comes from supplier Delphi and is called Dynamic Skip Fire (DSF). According to Car and Driver, this cylinder deactivation technology will be featured on models powered by the 5.3-liter V8 engine and the 6.2-liter V8 engine. All in all, Delphi calculates fuel efficiency improvements of up to 5% for GM trucks.
Cylinder deactivation appeared in Chevy and GMC models as far back as 2005, but the technology has not seen large innovations since then. This marks the greatest level of improvement to cylinder deactivation technology for GM since it was introduced.
According to Car and Driver, criticism for cylinder deactivation technology has long been that the cutoffs of specific cylinders are graceless in their transitions. This new fuel-saving cylinder deactivation promises to be much less noticeable.
The 2019 Chevrolet Silverado 1500 and GMC Sierra 1500 will be available at Dahl Chevrolet Buick GMC later this year.
