Saab 93 Monster: The Twin-Engine Beast That Pushed Boundaries
In the 1950s Saab engineers created the Saab 93 "Monstret" by mounting two 748cc three‑cylinder two‑stroke engines in the front, effectively forming a 1.5‑liter twin‑engine powerplant that produced about 140 hp for rally testing. The result was a terrifying, understeer-prone beast with brutal torque, clocking around 122 mph in testing but never intended for production. The project taught Saab important lessons about chassis limits and helped steer the brand toward later turbocharged designs, with the Monster now housed in the Saab Car Museum.
