The ABC Hornet was an 80 hp (90 kW) four-cylinder aero engine designed in the late 1920s by the noted British engineer Granville Bradshaw for use in light aircraft. The Hornet was effectively a double Scorpion and was built by ABC Motors, first running in 1929.Lumsden 2003, p. 54.

In 1931 the engine was re-designed, including the adoption of the new Hiduminium alloys for the crankcase, exhaust manifolds and pistons.{{cite journal
