History

In 1931 a truck manufacturing plant was established in Finland in order to make exceptionally robust trucks for use in extreme arctic conditions. The trucks were given a name that does justice to their properties..SISU.
1938 The first prototype of an armoured car saw daylight.
1943 SISU manufacture was utilised in serving the Finnish Defence Forces. After the 1950’s SISU manufactured not only extremely robust trucks, but also trams and buses.  
1962 SISU manufactured its first prototype 4x4 off-road truck in collaboration with the Finnish Defence Forces. The vehicle was called the Proto throughout its lifespan.
Since 1970's SISU vehicles have been a common sight in UN peacekeeping operations worldwide.
1996 SISU was awarded the ISO 9001 and AQAP 2110 quality certificates of the Finnish Defence Forces. SISU began to use cabins and engines manufactured by Renault in their vehicles.
1998 The SISU HMTV 6x6 was presented and..
2000 the SISU HMTV 8x8. The vehicle combines the mobility of an off-road truck and the practicality of a civilian truck. It also has favourable life-cycle costs.
2006 Sisu introduces a brand new range of off-road trucks. The top-of-the-range model is the 10x10 vehicle, which can for instance be used as a platform for a 26-metre bridge - a much lighter alternative than a tank. All models can be equipped with ballistic and land mine protection.
