UMM Uniao Metalo Mecanica.
UMM four wheel drive: Uniao Metalo Mecanica Ltda, Rua das Flores, 71 - 1200 Lisbon Portugal.
The UMM four wheel drive design is derived from a previous design from France called the Cournil. This was developed by a French farmer who recognised the need for an all purpose vehicle. This explains the fact that some of the parts are of French origin. The engine and transmission are from Peugeot, the heater is a Renault part and the switches and instruments are also from Peugeot.
Many Umms are in use by utilities in Spain and Portugal and are also in use by Police, Fire service and military. They are also popular in France. A few hundred (estimate) have been sold in the UK and there is a small owners club with around 60 members.
The model line started with the TRANSCAT which was replaced in the mid eighties by the most popular model the ALTER (known in some areas as the ALFOR). This has been revised to become the ALTER II.
