The DK was a Danish automobile built as a prototype by S. A. Mathiesen in 1950. It was supposed to combine American comfort with European dimensions and economy. It featured a chassisless aluminum body, a Heinkel engine and a ZF Friedrichshafen gearbox. It remained a prototype, but in 1953 a new, modified version was introduced as the DKR. A few dozen were built, until 1954.
