In search of a green, gutsy engine, MPT chose the downsizing strategy and put the company’s 50-plus year legacy of engine acumen to work on designing a demonstration model that would decrease engine size by a whopping 50 percent and, as a result, cut fuel consumption by 30 percent-all the while delivering comparable performance. In the quest for improved operating efficiencies, automotive engineers have tried direct injection, variable valve trains, controlled auto-ignition or homogeneous charge compression ignition, and engine downsizing. “Consumers want greener cars, but they want them to have the same performance as their older, larger models,” said Mark Stephenson, Chief Engineer of Predictive Analysis at MAHLE Powertrain (MPT), a leading international engine development partner and manufacturer in Northampton, U.K. ![]()
