Who Invented The Hemi Engine? (it Wasn't Dodge)

The history of nan first Hemi engine from Dodge is beautiful straightforward, but it turns retired that nan communicative down nan first engines pinch hemispherical combustion chambers requires going down a overmuch deeper rabbit hole. And it's 1 filled pinch contradictory claims, celebrated names, and plentifulness of random information points. One measurement to link nan dots, though, starts pinch Augustus Herring.

Better known for his aviation activity — including a pre-Wright Brothers powered formation successful 1899 — Herring seems to person been moving connected an motor pinch hemispherical combustion chambers earlier 1900, and his shop astatine nan clip happened to beryllium located wrong a abstracted mill owned by Truscott Marine. Now, it's not clear precisely really it happened, but soon aft this, Truscott came retired pinch its ain motor featuring hemi heads. 

How did nan hemi get from boats to cars? In different coincidence, Truscott astatine nan clip besides had its ain foundry, and 1 of its extracurricular jobs was casting engines for Allie Ray Welch, who had built a benignant of semi hemi of his ain successful 1902. It did person a hemispherical combustion chamber, but non-standard valves and "disc" actuation, truthful it isn't considered portion of nan existent hemi heritage.  And a fewer years later, successful 1905, Welch patented an motor pursuing nan aforesaid creation that went from Herring to Truscott — and it began appearing successful cars from nan Welch Motor Car Company. Yet that's still not nan full story.

While nan Welch cars were connected nan roadworthy successful 1905, personification other was moving to get hemi-style engines into title nether nan guidance of Carl Fisher, who was beautiful keen connected motorsports. In fact, he went connected to recovered nan Indianapolis Motor Speedway and nan Indy 500, an arena that's still showing group understand nan entreaty of racing today.

In 1905, however, Fisher was much willing successful competing successful nan Vanderbilt Cup, which would pit America's apical cars against nan champion from Europe. His Premier Motor Manufacturing Company led nan effort, pinch technologist George Weidley designing a title car powered by a monstrous four-cylinder centrifugal displacing much than 923 cubic inches and making 100 horsepower — each enhanced by hemispherical combustion chambers. There was a imaginable Truscott relationship here, too, since 1 relationship reports Weidley sewage nan thought from seeing hemi exertion utilized connected a boat.

The Premier title car fell afoul of nan Vanderbilt Cup rules and wasn't allowed to tally nan event, but get fresh for much coincidences. Carl Fisher was besides nan section supplier for Stoddard-Dayton cars, which, wouldn't you cognize it, began featuring engines pinch hemispherical combustion chambers successful 1908. Stoddard-Dayton would autumn connected difficult times successful nan years ahead, spell done plus income and re-orgs, until successful 1925, nan remains would extremity up pinch nan modern-day Hemi hero, Chrysler.

Sometimes successful science, 2 inventors look to travel up pinch nan aforesaid thought independently. You know, for illustration Newton, Leibniz, and calculus, aliases Darwin, Wallace, and evolution. Well, this appears to person happened pinch hemi engines.

There's nary nonstop grounds of Herring's conception crossing nan ocean, but successful yet a further spot of synchronicity, a Daimler vessel motor featured hemi-like heads successful 1902. By 1904, a Belgian automaker named Pipe, moving pinch ex-Daimler technologist Otto Pfander, was producing cars pinch hemi engines. There's nary evident link, yet astatine astir nan aforesaid period, an Austrian technologist named Hans Ledwinka was processing a akin motor for nan institution that would yet go Tatra, and prototypes were built earlier 1910. 

Ledwinka, successful turn, was friends with, and possibly a distant comparative of, Ferdinand Porsche. Their chats were apparently capable to animate nan second to create an motor pinch hemi heads for Austro Daimler, wherever he was employed astatine nan time. (Austro Daimler was a licensee of nan German car brand, but past again, the Daimler sanction was ever confusing people.) The mill displaced a Hemi-friendly 5.7 liters, propelling a trio of 1910 Austro Daimler 22/86 touring cars — thoroughfare ineligible astatine nan clip — to a cleanable expanse of nan podium astatine that year's Prince Heidrich Trial. The consequence was nan building "Race connected Sunday – Sell connected Monday?" business for hemi engines, which quickly recovered favour successful Europe (per Racing Vintage Cars).
