A hemispherical head ("hemi-head") gives an efficient combustion chamber with minimal heat loss to the head, and allows for two large valves.However, a hemi-head usually allows no more than two valves per cylinder due to the difficulty in arranging the valve gear for four valves at diverging angles, and these large valves are necessarily heavier than those in a multi-valve engine of similar ...
2005 was the last year for the first version of the 5.7 L (345 cu in) Hemi V8. 2006 half-ton models offered the Multi-Displacement System Hemi V8 engine that also became available in Chrysler and Dodge sedans. This engine featured the same performance but had a cylinder-deactivating feature enabled under light loads to increase fuel economy by ...
Chrysler developed its first experimental hemi engine for the Republic P-47 Thunderbolt fighter aircraft. The XIV-2220 was an inverted V16 rated at 2,500 hp (1,860 kW). The P-47 was already in production with a Pratt & Whitney radial engine when the XIV-2220 flew successfully in trials in 1945 as a possible upgrade, but the war was winding down and it did not go into production.

Larger and more powerful engines were available up to the 426 cu in (7.0 L) Hemi V8. Positioned as a sports-type luxury model, sales of the 1966 and 1967 Chargers were low.

Chrysler's Multi-Displacement System (MDS) is an automobile engine variable displacement technology. It debuted in 2005 on the 5.7 L modern Hemi V8.Like Mercedes-Benz's Active Cylinder Control, General Motors' Active Fuel Management, and Honda's Variable Cylinder Management, it deactivates four of the V8's cylinders when the throttle is closed or at steady speeds.
