When did the Dodge 5.7 Hemi engine change?
If the 345 HEMI were a below average engine it’s unlikely Chrysler and Dodge would keep it around for so long in their flagship cars. In 2009, the 5.7L engine was revised to improve emissions, fuel economy, and performance. The revised engine is known as the 5.7 Eagle. A few notable updates to the 5.7 HEMI include:
What kind of engine does a Dodge Challenger have?
And it appears it’s time might be up. According to Allpar, FCA is supposedly working on a new inline-six turbocharged engine that will either meet or beat the Hemi’s power ratings while offering a smoother torque curve. The current Dodge Challenger, one of many vehicles where this Hemi is used, produces up to 375 hp and 410 lb-ft of torque.
What’s the RPM on a Dodge Challenger Hemi?
It has a 5.7 Hemi MDS in it. 55mph, in 8th gear, knocking down the big MPG numbers….but only turning over 1300-1400 RPM. Anything less than 55mph it refuses high gear (even on an easy downhill coast). I wonder if that is as-designed in the PCM specifically to keep the RPMs up above a minimum requirement for lubrication?
Is the 5.7 Hemi engine good for gas mileage?
When cruising the 5.7 Eagle HEMI engine (2009+ update) utilizes multi-displacement technology to shut down 4 of the cylinders. It’s a great way to improve emissions and fuel economy. On the surface there’s nothing wrong with MDS. The power from the large 5.7 liter displacement is still there when you need or want it.

What does Multi Displacement System do on Dodge Hemi?
Finally, Chrysler implemented multi-displacement system technology on the 345 HEMI. This allows the engine to shut down 4-cylinders in certain situations to improve fuel economy and emissions. These were solid updates, overall. However, as with any new technology there are always kinks that must be worked out over time.
