Patria Pasi variants

Patria Pasi variants, which were the choice of the defence forces of Finland for the armoured personnel carries to replace the aging Soviet BTR-60s was a result of the commercial competition between two Finnish companies, a tractor manufacturer Valmet and the lorry manufacturer Sisu, which won the contract with its prototype.

Prototypes and series

Patria Pasis have been produced in various models and also for various purposes. Originally Panssari-Sisu, was not produced by Patria, but Sisu lorry manufacturer. The other possible armoured personnel carrier which could have come in the question of a choice for the defence forces of Finland to replace BTR-60 was Panssari-Valmet, which did not win the competition.

Technically the variants of Pasi are marked with two letters XA, which means cross-country armoured vehicle, the first and second number means the power in tens of kilowats. Therefore, Pasi XA-180 means, that it is a cross-country armoured vehicle (XA) having an engine capable for 180 kW (18× 10 kW). The last number, 0, means that XA-180 is the first version of the 180 kW Pasi's.

Manufacturing companies

The name of the manufacturer has changed several times. Up until 1980 the producer was known as Oy Suomen Autoteollisuus Ab. In 1981 it changed its name to Oy Sisu Auto Ab, which reflected the name of the Sisu branded lorries Suomen Autoteollisuus had manufactured. In 1994 Oy Sisu-Auto Ab purchased Valmet Oy's forest tractor and harvester business, and additionally the production of the tractors and engines. Oy Sisu Ab was founded to function as the holding company of all the new entities and the old Oy Sisu-Auto Ab. For the lorry production, a new Oy Sisu-Auto Ab, now Oy Sisu Auto Ab, was founded.

In 1995 the military vehicle production profit center of Oy Sisu Ab, Sisu Defence is changed into a separate subsidiary company Sisu Defence Oy, which continues the military vehicle production with Masi, Misu, Nasu, Pasi, Rasi and Raisu lorries. In 1996 Sisu Defence was sold to Suomen Puolustusväline Oy, which is a state owned company. In 1997 Sisu Defence Oy merged with Suomen Puolustusväline to become Patria Vehicles Oy.[1]
