A brass chronometer ticks on a mahogany desk. A diesel engine coughs black smoke somewhere below deck. Both scenes belong to alternative twentieth centuries, but they run on different fuel. Steampunk imagines a world where steam power never surrendered. Dieselpunk builds one where the internal combustion engine shaped everything that followed, with all the grit and scale that implies. The difference is not just what spins the flywheel. It is what kind of world that flywheel produces.
Defining the Two Currents
Steampunk and dieselpunk are both “retro-futures”: speculative settings that take their technology, aesthetics and social logic from a specific historical energy regime and then push it forward. Steampunk draws from the Victorian and Edwardian eras (roughly 1837 to 1910), where coal-fired steam engines, brass fittings, clockwork and early electricity coexisted. Dieselpunk draws from the interwar period and World War II (roughly 1914 to 1945), where petroleum engines, steel, concrete, radio and early aviation defined the texture of daily life.
The fuel determines the feel. A steampunk airship is a dirigible with riveted cabins and canvas wings. A dieselpunk airship is a flying wing with turbine intakes and riveted aluminum. One smells of coal dust and beeswax. The other smells of gasoline, tar and cordite.
Where the Terms Came From
The word steampunk appears in print by 1987. Author K.W. Jeter used it in a letter to Locus magazine to describe the work of Tim Powers, James Blaylock and his own novel Morlock Night. Jeter wanted a label for Victorian fantasy with speculative technology, a counterpart to cyberpunk. He got one.
Dieselpunk took longer to solidify. The term appears in the late 1990s and early 2000s, attributed to game designers and fans who wanted a label for the interwar pulp aesthetic that did not fit under either steampunk or cyberpunk. The video game Grim Fandango (1998) and the Savage Worlds setting Daring Tales of the Sprawling Void helped push the name into use. By 2004, the website Dieselpunks.org was curating the genre, and by 2010 the term had enough traction to appear in academic writing on retro-futurism.
The History That Each Genre Draws On
Steampunk borrows from the same decades that produced Jules Verne, H.G. Wells and the Great Exhibition of 1851. The real-world technology it heightens includes the steam turbine, the electric telegraph, the submarine, the airship and the earliest automobiles. The social structures it engages (and often critiques) are British empire, industrial capitalism and rigid class hierarchy. Mary Shelley’s Frankenstein (1818) is often cited as a precursor, though it predates the steam aesthetic by a full generation.
Dieselpunk draws from the pulp magazines of the 1920s and 1930s: Amazing Stories, Weird Tales, The Shadow. It builds on the technology of the interwar period: the fighter plane, the tank, the ocean liner, the radio tower, the skyscraper. Its historical shadow is the Great Depression, rising fascism and the mechanized warfare that killed millions with assembly-line efficiency. The genre never fully escapes that shadow. Even in its most optimistic expressions, dieselpunk carries the noise of engines running for a war that has not yet ended.
What the Two Genres Actually Look Like
Steampunk materials: brass, copper, bronze, mahogany, leather, canvas, glass, cast iron. Colors: brown, gold, olive, cream, rust. Fasteners: rivets, screws, clockwork gears. Power source: steam boilers, clockwork springs, early electric batteries.
Dieselpunk materials: steel, chrome, concrete, Bakelite, aluminum, canvas, rubber. Colors: olive drab, khaki, navy, charcoal, blood red. Fasteners: welded seams, bolt plates, cathode tubes. Power source: internal combustion engines, turbines, radio tubes.
A steampunk vehicle is a steam car or a propeller-driven airship encased in wood and brass piping. A dieselpunk vehicle is a Panzer tank or a Lockheed Constellation covered in stressed aluminum and decals. One looks like a Victorian drawing room bolted to a locomotive. The other looks like a factory floor that learned to drive.
Symbolism: What Each World Means
Steampunk is a world of invention without consequence. The machines are intricate, handmade and usually safe. The inventor is a gentleman (or gentlewoman) working in a well-lit workshop. Engineering is a form of craft, and craft is a form of moral character. The genre often romanticizes the Victorian faith in progress, even when it critiques the empire that progress served. The brass gear functions as a symbol of intelligence, patience and the belief that a clever mechanism can solve almost anything.
Dieselpunk is a world of power without restraint. The machines are mass-produced, brutal and designed for maximum force at minimum cost. A diesel engine does not care who you are. It runs until it runs out of fuel or breaks. The genre does not romanticize progress. It stares at what progress cost: the factories that consumed whole towns, the bombers that leveled cities, the propaganda that turned citizens into soldiers. The rivet and the turbine are not symbols of ingenuity. They are symbols of scale, indifference and the fact that a system can be efficient and morally empty at the same time.
Both genres occlude as much as they reveal. Steampunk rarely addresses the coal miners whose labor powered the engines it celebrates. Dieselpunk rarely shows the oil fields that fed the tanks it sends across its landscapes. The genres are fantasy, and all fantasy chooses what to remember.
The Tone and the Story Each Genre Tells
Steampunk stories tend toward adventure and intrigue. The protagonist is often a rogue, an inventor or a detective who uses cleverness to outmaneuver a corrupt establishment. The tone ranges from earnest (Jules Verne) to satirical (Alan Moore’s The League of Extraordinary Gentlemen). The mood is expansive. The world is large enough to escape into.
Dieselpunk stories tend toward survival and sacrifice. The protagonist is often a soldier, a pilot or a smuggler caught between rival powers that care nothing for individuals. The tone is pulpy at best, grim at worst. The Rocketeer (1991) and Captain America (2011) sit at the optimistic end. Metropolis (1927) and Darkest Hour (2017) sit at the other. The mood is claustrophobic. The war is everywhere.
How They Compare to Adjacent Genres
Steampunk versus clockpunk. Clockpunk replaces steam with clockwork. It usually drops the Victorian setting for the Renaissance or early Enlightenment. Leonardo da Vinci’s sketches are clockpunk’s founding documents. The genre is rarer and more fragile: clockwork does not convincingly power an airship the way steam does.
Dieselpunk versus atompunk. Atompunk draws from 1945 to 1965: nuclear reactors, transistors, plastics, the Space Race. Where dieselpunk is dirty and dark, atompunk is clean and bright. The aesthetic is “Googie” architecture, bubble cars, white tiles and chrome diners. The classic example is The Jetsons (1962). Dieselpunk’s oil grime and atompunk’s atomic sheen share a midcentury root but diverge sharply in mood.
Sourced from the Le Grand Grimoire glossary, we define both clockpunk and atompunk as subgenres of the broader retro-futurism family. Each one picks a different energy source and builds a different imaginary world around it.
Common Misconceptions
Misconception: Dieselpunk is just steampunk with tanks. The two genres differ in their foundational technology, their social assumptions and their emotional register. A tank does not make a setting dieselpunk any more than a dirigible makes it steampunk. The fuel, the materials and the historical sensibility must align.
Misconception: Both genres are purely visual. Each genre carries a distinct narrative logic. Steampunk plots center on discovery, craftsmanship and social mobility. Dieselpunk plots center on conflict, survival and the collapse of institutions. The visuals follow the story logic, not the other way around.
Misconception: Steampunk is Victorian and dieselpunk is WWII. The historical windows are broader. Steampunk can stretch into the Edwardian era (up to 1914) and even the Gilded Age (1870s). Dieselpunk can stretch from 1914 into the 1950s, as long as the dominant technology remains piston engines, analog electronics and mechanical control systems. What matters is the energy regime, not the decade.
FAQ
Which came first, steampunk or dieselpunk? Steampunk. The term was coined in 1987. Dieselpunk emerged as a named subgenre in the late 1990s and early 2000s.
Can a setting be both steampunk and dieselpunk? Rarely. Mixing steam and diesel technology is possible but the genres carry incompatible social logics. A dieselpunk steampunk world usually reads as steam technology with dieselpunk story values, or vice versa.
Why is dieselpunk darker than steampunk? Dieselpunk draws from the interwar period and WWII, decades defined by economic collapse and industrial warfare. Steampunk draws from the Victorian period, which its core texts treat as an age of exploration and invention.
What is the most commonly cited example of each genre? Steampunk: The Difference Engine by William Gibson and Bruce Sterling (1990). Dieselpunk: the Sky Captain and the World of Tomorrow film (2004).
