Fibreglass was a relatively new material in the late 1950s, but had numerous benefits, notably its inability to rust and its light weight (being approximately 130 kg (290 lb) lighter than an equivalent metal-bodied car).

Gutbrod also manufactured the Troll's engine, which was a 700 cc (43 cu in) two-stroke straight-twin with Bosch fuel injection connected to a three-speed Hurth transmission.

[1] The Troll was developed by businessman Per Kohl-Larsen and engineers Bruno Falck and Erling Fjugstad,[1] and designed by Hans Trippel.

Norwegian and foreign press showed much enthusiasm towards the project, and the car was compared to those from brands like Porsche, Citroën and Saab.

When the Norwegian government made their lack of support for the Troll clear, all potential investors closed negotiations, resulting in bankruptcy in early 1958.
