The current-production "HEMI" engine does not employ truly hemispherical combustion chambers; they are flatter and more complex than the 1950s–'70s Hemi V8 chamber. It uses a coil-on-plug distributorless ignition system and two spark plugs per cylinder to shorten flame travel leading to more consistent combustion which helps reduce emissions. There is one coil for every cylinder, and early versions{{vague|date=December 2008}} had a [[wasted spark]] ignition arrangement which would permit the engine to continue running on all eight cylinders with one failed coil.{{fact|date=December 2008}} Like most of Chrysler's past-model Hemi-head engines, the 5.7 version is rated at approximately one horsepower per cubic inch, however the updated 2009 model produces even more than that.{{vague|date=December 2008}} | The current-production "HEMI" engine does not employ truly hemispherical combustion chambers; they are flatter and more complex than the 1950s–'70s Hemi V8 chamber.
