Editing Straight-eight engine (section)

==Early period (1903–1918)==
The first straight-eight was conceived by [[Charron, Girardot et Voigt]] (CGV) in 1903, but never built.<ref name="Georgano">{{cite book|last=Georgano|first=G. N.|title=Cars: Early and Vintage, 1886–1930|year=1985|publisher= Grange-Universal|location=London}}</ref>{{page needed|date=October 2022}} Great strides were made during [[World War I]], as [[Mercedes (car)|Mercedes]] made straight-eight aircraft engines like the [[Mercedes D.IV]]. Advantages of the straight-eight engine for aircraft applications included the [[aerodynamics|aerodynamic]] efficiency of the long, narrow configuration, and the inherent balance of the engine making counterweights on the crankshaft unnecessary. The disadvantages of crank and camshaft twisting were not considered at this time, since aircraft engines of the time ran at low speeds to keep propeller tip speed below the speed of sound.

Unlike the V8 engine configuration, examples of which were used in [[De Dion-Bouton]], [[Bi-Autogo (automobile)|Scripps-Booth]], and [[Cadillac V8 engine|Cadillac]] automobiles by 1914, no straight-eight engines were used in production cars before 1920.
