Today’s HEMI

Today’s HEMI engine has come a long way since its debut in the 1950s. Today, the HEMI is still used in many high-performance vehicles and offers an unparalleled level of power, efficiency and reliability. The overall design of the engine contains a hemispherical cylinder head with two valves per cylinder, creating a powerful combustion chamber that maximizes air flow for maximum output. This design gives the HEMI its distinctive character and helps it stand out from traditional engines. Additionally, modern-day HEMIs are equipped with improved electronic fuel control systems that increase power while lowering emissions, making them some of the most technologically advanced automotive engines available today.

Dodge Challenger and Charger

In recent years, the Modern HEMI engine has become iconic for its contribution to some of the greatest muscle cars of all time. Spearheading this classic car renaissance are the Dodge Challenger and Charger, whose power is propelled by the Modern HEMI engine. But they’re not alone. The Modern HEMI can be found in several other classic models, such as the Ram pickups and Dodge Durangos, giving them an unbeatable combination of style and power. There is no doubt that Modern HEMI-powered cars will continue to fascinate auto enthusiasts for generations to come.


The HEMI engine was first created in the 1950s by Chrysler. The engine was designed to be more powerful and offer better performance than other engines available at the time. As a result, the HEMI engine quickly became popular in racing and performance cars. Today, the HEMI engine is still used in many high-performance vehicles.
