MPG in 2019 Chevy Silverado pickup truck has been boosted! It looks like GM’s investment arm, GM Ventures, has borne some real-world, fuel-saving fruit.
Sophisticated engine-control algorithms under the hood of the 2019 Chevrolet Silverado full-size pickup truck, which make the truck’s V-8 engines more efficient, came from work done by a company GM bought in 2012.
That year, GM Ventures sank an undisclosed amount of cash into Tula Technology, a Silicon Valley startup that had developed software to provide a more flexible way to deactivate individual cylinders under varying power demands.
In the outgoing generation of GM full-size pickups, cylinder deactivation can reduce the number of cylinders used from eight to four to save fuel.
However, the technology from Tula gives powertrain engineers the ability to vary the number of active cylinders from one to eight.
Tula’s “Dynamic Skip Fire” technology couldn’t be possible without the power of the latest processors for automotive computing.
At the time of its investment, GM said the software would boost fuel economy by as much as 15 percent over engines without cylinder deactivation.
Tula’s technology—now called Dynamic Fuel Management—will be used on the two V-8 engines announced so far for the 2019 Chevy Silverado, though not on the new 3.0-liter inline-6 turbodiesel also announced.
The company said at its launch the 2019 truck would have six engines and transmissions, though it gave details only on those three engines and a new 10-speed automatic transmission.
GM has used several other fuel-saving tricks in its trucks, including a spoiler atop the trailing edge of the cab roof and vents ahead of the front wheel wells that smooth the airflow around the front wheels.
The vehicles have also shed an impressive 450 pounds over comparably equipped versions of the outgoing Silverado generation, Chevy said when it showed the trucks before last week’s Detroit auto show media days.
While GM has not committed to electrifying its new full-size pickup truck, the other two Detroit truck manufacturers have.
