Chevy today announced that a new engine valve technology will help the 2014 Impala sedan, coming next year, to achieve better fuel economy. The intake valve lift control system opens the valves only slightly to the “low lift” position, giving the 2.4-liter four-cylinder lump better economy under normal driving. In the “high lift” position, maximum air flow is ensured to provide the most power.
“Intake Valve Lift Control works so seamlessly drivers aren’t likely to notice it at all,” said Mike Anderson, GM global chief engineer for Ecotec engines. “What they will notice is a fuel savings of up to one mile per gallon.”
