| The
Allison V-1710 was the only U.S. liquid-cooled production
engine of World War II and the first engine designed from the start
to use ethylene glycol (prestone) coolant.
Design began in 1930 to replace the Maybach
engines used by the U.S. Navy's airships. The contract was
cancelled before the first engine was delivered after the airship Macon
crashed in 1935. A redesigned engine passed its type-test in
1937 at 1,000 hp. Flight tests led the U.S. Army to push the
use of the V-1710 in its new generation of fighters.
Lack of an adequate supercharger inhibited
high-altitude performance; however, around 47,000 were built by the
end of World War II.
