The Dodge M4S is an American high performance prototype sports coupe originally engineered, designed, and built by Dodge in 1981 as a technology demonstrator vehicle. It was designed by then chief designer of Dodge, Bob Ackerman.[1] The designation M4S denotes "Midengine, 4 cylinder, Sport“.

The car was made famous by its appearance in The Wraith, a 1986 supernatural film. The mid-engined car had a tested and confirmed top speed of 194.8 miles per hour (313.5 km/h)[1] and could go from 0 to 60 miles per hour (97 km/h) in 4.1 seconds, with more than 440 horsepower (330 kW) under the hood coming from its relatively small displacement (especially by American standards) 2.2L 4 cylinder forced induction engine.[2][3]

Its twin-turbo induction system was quite revolutionary and pioneering, and is said[by whom?] to have influenced car makers such as Toyota and Porsche, which a number of years after the M4S was first presented also employed twin turbo setups, namely Toyota on its Supra sportscar, and Porsche on its 959.[4]

Although Saab was the first automaker to mass-produce a turbocharged version of if model 900 back in 1977, and the first use of the "Turbo" badge in a street legal vehicle was from Porsche' 939 (1979), the first street legal twin-turbo setup came from Maserati's aptly-named "BiTurbo" in 1981, and the application of twin turbocharging of Porsche came three years earlier in their 1976 Le Mans 935 racecar.[5]

The car has since gained an enthusiast cult following, prompted by the fame it gained from appearing in The Wraith.[6][7]
