Vehicles with turbochargers will account for 48% of annual global sales by 2021, up nine percentage points from this year, according to a forecast from Honeywell’s Transportation Systems. The trend to bigger engine sizes in China and Europe, as powertrains are adapted for increasingly strict emissions regulations, and eventual right-sizing of engines is expected to support electric boosting products, supporting an industry shift from 12- to 48-volt battery systems. “Electric vehicles have the potential to be more efficient than internal combustion engines, but they also need better performance at lower speeds,” said John O’Grady, senior vice president of research at IHS.
