The Dodge ESG 6.4 liter engine (or HEMI 6.4) is a powerful 8-cylinder unit that has been produced since 2010 at a plant in Mexico. It is designed to be installed in sporty and high-performance models from Dodge, Chrysler, and Jeep, including the Challenger, Charger, Grand Cherokee, and Durango with the SRT8 index.
This engine is an upgraded version of the famous HEMI motors with improved performance. It is equipped with a number of modern technologies, such as the system of disconnection of half cylinders MDS (Multi-Displacement System), which allows to reduce fuel consumption at low load, and VCT (Variable Cam Timing), which improves the operation of the timing mechanism.

Disadvantages, breakdowns and problems of the Hemi 6.4 engine
Despite its power and reliability, the ESG 6.4 liter engine is not without some drawbacks:
- High fuel consumption. Even with the MDS system, the motor is still “voracious”, which does not always satisfy owners.
- Demanding the quality of oil. For correct operation of hydrocompensators and MDS system it is necessary to use high quality oil, recommended by the manufacturer – 5W-20.
- Problems with the EGR valve. If poor quality fuel is used, the exhaust gas recirculation (EGR) valve can become dirty and begin to seize.
- Exhaust manifold. Problems with the exhaust manifold are common – it can warp and the mounting studs can break.
- Hemi ticking sounds. As with other HEMI engines, owners may encounter a characteristic sound described as “Hemi ticking.”
Is the HEMI 6.4 engine reliable?”
The Dodge ESG 6.4 liter engine is a high-performance powertrain that combines power, reliability, and modern technology. However, its main drawback is its high fuel consumption, even with the MDS system. Nevertheless, the ESG engine remains the choice of those who value performance and impressive dynamic characteristics.
