A History of HEMI Engines | Palm Coast, FL

After the war efforts of the 40's ceased and automakers went back to making automobiles, there was a massive boost of innovation where many different kinds of engines were born. This is precisely what happened when Chrysler developed the first HEMI engine as far back as 1948, an engine that would go into production in the 50's and become one of the most lauded aspects of the muscle car era.

The first HEMI was a 6-cylinder engine crafted for the Jaguar. Then, in 1951, a more refined HEMI V8 - known as the "331 HEMI" for its 331 cu. in. displacement - was offered on a wider variety of Chrysler vehicles. Innovation kept pushing the limits of what the HEMI could do until the 426 HEMI propelled Chrysler's vehicles into NASCAR stardom. The 426 HEMI is still used in the lineup today.

The name "HEMI" comes from the engine's design, which includes a "hemispherical," or half-sphere-shaped, combustion chamber. This design improves the engine's thermal efficiency over flathead engines. Valves in a HEMI engine are also typically large, allowing for better airflow, and HEMI engines were also engineered to improve emissions, too.

All of these aspects of the HEMI engine's design allow for a better and more innovative performance, which is why HEMI engines are still utilized in a variety of vehicles under the FCA umbrella. Capable Dodge performance cars and RAM trucks alike still pack the power of the HEMI under their hood because it allows them to churn out plenty of power without wasting a drop of fuel.
