HEMI (Eagle)

5.7L V8

A torquey, deep-chested pushrod V8 with the unmistakable HEMI rumble, delivering effortless low-end grunt for towing while quietly dropping to four cylinders when you lift off.

Chrysler revived the legendary HEMI name in 2003, and the 5.7L gained its 'Eagle' revision in 2009 with variable valve timing; the HEMI lineage traces back to Chrysler's hemispherical-head engines of the 1950s muscle era.

• Its Multi-Displacement System can deactivate four of the eight cylinders under light load to save fuel, then seamlessly wake them when you ask for power.
• The modern Gen III HEMI actually uses a quasi-hemispherical chamber rather than a true hemisphere, keeping the famous name even as the science moved on.
