Indiana Historical Society Allison Engine Co. Page 1 HISTORICAL SKETCH

James A. Allison founded Allison Speedway Company that later became the Allison Engineering Company. When Allison died in 1928, bought Allison Engine Company and the company became the Allison Engine Division. Its primary focus was the production of aircraft engines. Allison developed aircraft engines that were then used by the military in World War II. In 1946, Allison Engineering was divided into aircraft operations and transmission operations, and in 1970 merged with Engine Division, becoming Detroit Diesel-Allison. In 1983, Detroit Diesel Allison Operations and Transmission Operations was split into Detroit Diesel Allison Division (DDA) and Allison Gas Division. In 1987 the diesel portion of DDA was sold to Roger Penske, and the remaining portion of the company was reorganized as Division. In the early 1990s, Allison split into Allison Gas Turbine Division and Allison Transmission Division. In 1993 Allison Gas Turbine Division became the Allison Engine Company, which was sold to Rolls Royce in 1995, but Allison Transmission remained a separate company. In the 1930s, Allison began experimental development on a 1000 horsepower reciprocating, liquid cooled . The V-1710 was finished in 1939 and was the first aircraft engine used by the military that was rated for 1000 horsepower. Allison produced more than 70,000 engines during World War II for the Allied war effort. Although it powered roughly 60% of the fighter planes in World War II, the V-1710 was controversial as an engine, with many critics accusing it of being a second-rate engine for use in the war. This was due to the poorer performance that smaller, cheaper versions of the engine had at higher altitudes. Once turbocharged, however, the engines performance was greatly boosted, and as the war progressed, steps were taken to fix this problem, making the engine much more reliable.
