Volvo Cross Country C303, (TGB11, A.K.A "Terrängbil 11", translated as "Terrain Vehicle 11"), is the base model of a range of military vehicles produced by Volvo. The car was developed in the late 60s based on the successful L-3314 series and went into production in 1974. This version was produced both as a 4x4 and a 6x6. An 8x8 was planned but dropped. Engines were the B30 (B20 in the prototypes) from Volvo's civilian cars. The C3 series feature portal axles with locking differentials resulting in very high ground-clearance (similar to the Unimog) and outstanding performance offroad. The cars are narrow to make it possible to navigate between trees and on narrow forest roads.
