The Medusa is based on the chassis and mechanics of the Lancia Montecarlo, and thus uses the same mid mounted 2.0 L (2,000 cc) Lampredi I4 engine, producing 120 PS (88 kW; 120 hp) at 6,000 rpm and 170 Nm (125 lb ft) of torque, coupled to a 5-speed manual transmission from that car.

The original the clay model reportedly had achieved a lower reading of 0.255 Cd, but the addition of side mirrors, indicator repeaters and a radiator caused it to go up.

[2] The Medusa featured many design elements that were tailored to help it achieve better aerodynamics.

Features such as pop up headlights, door handles and window glazing that sit flush with the body, inset turn signal repeaters and doors that wrapped up into the roof all helped the Medusa to be as aerodynamic as possible.
