Dodge ESD specs: 376 ci (6.2L) 8-cylinder, 4.091 x 3.579 in (103.9 x 90.9 mm) bore and stroke. Rated 707-1025 hp, 2015–2023. Used in the Dodge Challenger.

The Dodge Gen III Hemi (ESD) is oversquare — the 4.0906" bore exceeds the 3.5787" stroke by 14.3% — a layout that favors airflow and RPM over leverage at the crank. The 3.5787" stroke puts mean piston speed at 4,000 ft/min around 6,700 RPM, which is where a production bottom end is generally considered at its limit. Each of the 8 cylinders displaces 47.0 ci (770 cc).

It is one of 16 engines in the Gen III Hemi family, sitting between the 345 ci and 392 ci members. 23 factory variants share these dimensions, rated from 707 to 1025 hp across 2015–2023.
