The brothers Maurice and Georges Sizaire, of Sizaire et Naudin, manufactured automobiles in the early 19th century.

-Later the Sizaire brothers joined forces with F.W Berwick & Co and made high-end automobiles under the name Sizaire-Berwick.

-In 1919, Maurice Sizaire did a study on an aviation engine with 8 cylinders at a 90° V that should give 350 CV at 2,000 rpm, which with the reduction gear remained at 1300 rpm for the propeller. It had overhead camshafts and two magnetos between the V, and a Zenith carburetor. Another experimental design was a 600 HP V12 engine.

-Below we show a diagram of the Sizaire V8.
