X-Steam

X-Rayvers  Card #2/5  Copper/Black/Gold - 2026 Hot Wheels Mainline. X-Steam is a fantastical, steampunk-inspired original design featuring an exposed engine block styled like a Victorian-era steam engine, complete with visible pistons, a boiler-like housing, and copper-toned bodywork that evokes brass and riveted iron rather than modern automotive materials. It belongs to the X-Rayvers sub-series, a line built around vehicles with deliberately exposed mechanical internals so collectors can see the "guts" of the design, and sits at position 2 of 5 within that run. The teal racing stripe cutting across the copper bodywork adds a modern accent to the otherwise industrial-antique aesthetic. Steampunk-themed castings like X-Steam are a departure from Hot Wheels' usual muscle-car and supercar fare, appealing instead to collectors drawn to imaginative, mechanically expressive designs.
