Vanajan Autotehdas

Vanajan Autotehdas Oy (VAT) was a producer of heavy vehicles based in Hämeenlinna, Finland. The company was founded as Yhteissisu Oy in 1943 by the Finnish government and a number of major Finnish companies with the aim of producing lorries and buses for the Finnish Defence Forces. World War II was over before the company could start series production; it was renamed Vanajan Autotehdas and the marque became Vanaja. Subsequently, the production consisted of outdated lorry models, partly built from military surplus materials. After overcoming initial difficulties, the company modernised its products, became profitable and grew until the mid-1950s. Many major components, including engines, were imported. Diesel engines became widely available in 1955, and in 1959 VAT introduced its most significant innovation, the full load lifting tandem axle mechanism, which improved off-road capability significantly; the system is now used in Sisu vehicles.
