Volvo has always been a main supplier to the Swedish Armed Forces when it comes to vehicles in different segments, from staff cars, station wagons and high mobility cross-country vehicles to medium- and heavy-duty trucks, in standard execution or in all-wheel-drive execution with very good mobility also in terrain.
Cross-country all wheel-drive
The TL31 is a typical example of a series-produced cross-country all-wheel-drive Volvo truck with extremely high reliability and very long service life.
In the early 1950´s, the Swedish Armed Forces needed a new generation of heavy-duty all-wheel drive vehicles for e.g. towing of guns. In response to this, Volvo developed the TL31. This truck has a unique design and appearance but was, in fact, closely related to the L39 Titan when it came to the technical specification.
Still in use - after 40 years
The TL31 was (and is) an all-wheel-drive truck with a 9,6 litre diesel engine, which is normally naturally aspirated with an output of 150 bhp, but sometimes (e.g. when it came to the fire-fighting version of this basic truck) a turbocharged engine version of 185 bhp was utilized.
