The record

The C306 stretched the C304 for a longer body and served the Swedish Army as the Tgb 20 (ambulance, radio and cargo versions) and civilian and expedition owners after service; the 1983 Dakar class winner was a C300-series six-wheeler in most accounts.

AI rendering impression

An AI rendering impression starts from a 3D model of this vehicle, which an image model then paints into a scene. It is an artist's impression of the type, made to give a feel for the vehicle in its element — not a photograph, and not a record of any particular vehicle.

Proportions, fittings, markings, colours and the setting can all drift from the original in the process. For the vehicle's actual details, rely on the specification, the photographs and the cited sources on this page.
