Rob Dahm’s 13-Rotor Miata
Wednesday 4th November, 2026
For SEMA, Rob Dahm brought a Miata fitted with an eye-catching 12-rotor engine and a separate single-rotor engine that actually powers the car. The deliberately over-the-top build runs and moves under its own power, while the enormous display engine gives onlookers a reason to stop and wonder how it works.
Why it worked: It hijacked SEMA’s attention with a visual paradox—fully plumbed 12-rotor “engine” plus a hidden single-rotor drivetrain—creating irresistible curiosity and demo-ready proof it runs.
The lesson: Consider staging a jaw-dropping fake-out mechanism that looks functional, then reveal the real working core live to spark questions and coverage.
