The term “dieselpunk” was first coined to describe a darker, dirtier side of steampunk, informed by cyberpunk sensibilities, set in a post-steampunk era with a higher industrial level of development. Like steampunk colonizes the past of Victorian-Edwardian Scientific Romances and Voyages Extraordinaires with the present, dieselpunk transports modern-day technologies and attitudes into the era of mid-century pulp fiction—pulp refering to the inexpensive fiction magazines widely published from the 1920s through the 1950s, typically remembered for their sensational and exploitative stories and thrilling cover art.
Like steampunk exists within the framework of speculative fiction, dieselpunk resides under the banner of Pulp, specifically characterized by the rise of petroleum power and technocratic perception, incorporating neo-noir elements and sharing themes with Adventure Pulp.
