Chrysler developed their first experimental Hemi for use in the Republic P-47 fighter aircraft. The XIV-2220 engine was an inverted V16 rated at 2,500 hp (1860 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. However, the exercise gave Chrysler engineers valuable research and development experience with two-valve hemi combustion chamber dynamics and parameters.

In addition to the aircraft engine, Chrysler and Continental worked together to develop the air-cooled AV-1790-5B V12 Hemi engine used in the M-47 Patton tank.

I don't see any point that's American have around speed limits 80mph but who will go more than 160mph with Hemi engine? 0-60mph sec is awful.

I didn't have problem with it when we had snow.. I realized that I was lucky not to get one with Hemi because Durango w/ 5.7 Hemi engine requires 16 sparkplugs YIKE!! IF you don't believe me, Just check out Dodge dealership! Gas mileage is pretty much the same as 4.7 L.
