The KP Special was based on Uno Jensen's Alfa Dana production car (itself based on a Cooper Mk IX). The KP had a standard Alfa Dana chassis but civil engineer Per Krogh of the Ecurie Centre Nord opted for a different suspension set-up. The front had a combined coil spring and damper unit with double wishbones, while the rear suspension featured pendulum axles and vertical coil spring and damper units, fixed at the top to a reversed wishbone-type construction which extruded from the bodywork into the air stream (making the car's rear-end look very much like a starved cow whose bones were almost penetrating the sloppy hide!). The KP Special was raced by Viggo Petersen, during 1958 but the car did not feature more than the regular Alfa Danas, possibly because he was running a JAP engine for much of the year.
