With a goal of building new, smaller turbocharged power plants, Fiat Chrysler Automobiles (FCA) needed to create a new aluminum engine alloy to handle the increased temperatures. A research project with Oak Ridge National Laboratory and casting supplier Nemak has developed a new aluminum alloy that retains its strength to 572°F. The new engine is a 2.0L 4-cylinder turbocharged engine rated at 270 HP. Interestingly, 30 years ago, Chrysler offered a 2.2L turbocharged power plant delivering up to 225 HP. What’s old is new again.
