Mystery Surrounds Hemi Upgrades

by David Zatz on

Sources have told Allpar that the 5.7 and 6.4 Hemi V8s are both being upgraded, but details remain in short supply.

The engines are still competitive, but direct injection would raise low-end torque for the 5.7 and increase economy for any Hemi.  Chrysler is reportedly buying CAFE credits, despite the class-leading Ram diesel pickups, robbing from ready cash. Thus, there is some urgency to increasing fuel economy, and the likelihood of a stop-start system.

The changes will not come in time for the 2016 model year, according to our sources. We still don’t know which car will be the first to get updated Hemis, or if the company can meet their timetables. Both engines’ upgrades have been in the works for quite some time, but there’s a possibility that they won’t arrive until 2018.
