Engineers push engine, transmission technologies to turn off fuel usage.

Commercial-truck powertrains are doing more with less. Engine developers are adding features that reduce fuel consumption, saving owners money while helping fleets reduce emissions. Digital technologies continue to transform commercial trucking as powertrain providers devise new ways to eke more from each drop of fuel. Engines now adapt to road conditions, adjusting power and shutting down some or all of the cylinders as demands change.

Electric fans and maintenance monitoring now are being used to help keep engines running at maximum efficiency while using less fuel. Design teams also are refining technologies like start-stop and cylinder deactivation, working to make them smooth enough that drivers barely notice the systems are adapting to the environment.
