The Benz Bz.IIIb was an eight-cylinder, water-cooled, V-engine developed in Germany for use in aircraft in 1918.
Inspired by the Hispano-Suiza 8, some of which were captured and tested, the Benz Bz.IIIb was a fairly large engine, but its performance was disappointing. Despite not being accepted for service use a number of late World War I prototype German aircraft used the Bz.IIIb and the Benz IIIbo.
