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 in which GM invested several years ago. In 2012, 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.

You may not know this, but internal combustion engines are only efficient during a tiny part of their total operating range. And that means when driving at lower speeds when demand on the car’s engine isn’t large, your car might not get the gas mileage you’d expect.
