The Lancia Medusa is a concept car built by Lancia and debuted in 1980 at the Turin Auto Show. It was designed by Giorgetto Giugiaro.
When it was designed by Giorgetto Giugiaro, the car was designed to be as aerodynamic as possible.
Their main target was to achieve an aerodynamic efficiency of 0.25 cd and achieved 0.263 with the final design.
The original clay model achieved the targeted 0.255 cd efficiency, but the addition of side mirrors and side indicators and a radiator opening in the front resulted in achieving 0.263 cd.
The popup headlights, door handles, and window glazing that sits flush with the body, doors that were wrapped up into the roof, and inset turn signal repeaters were used to achieve better aerodynamic efficiency.
Despite being a four-door sedan body style, it featured an uncommon transverse rear mid-engine layout. Like many Lancia cars of the day the Medusa was also a rear-wheel-drive car.
The prototype was based on the Lancia Montecarlo and used the same mid-mounted 2.0-liter Lampredi inline-four engine. This engine produced 118 horsepower at 6000rpm and a maximum torque of 125 lb-ft when mated to a five-speed manual transmission.
Based on this concept, a derivative of the concept was produced for DeLorean Motor Company. The DMC 24 four-door sedan was a full-size scale car and was designed by Italdesign.
Italdesign also created a prototype for Lamborghini called Lamborghini Marco Polo. This version was a re-evaluation based on the DMC 24 concept.
The Lamborghini Marco Polo featured two massive gull-wing doors instead of four conventional-style doors. Just like the DMC 24 four-door sedan concept, this was also a full-size scale model without any mechanical components.
