UMM Alter 2000
In the year 2000, UMM launched a new version of the Alter, the Alter 2000. Equipped with a 2.1-litre Turbo Diesel engine built by Peugeot, this engine was quieter, more fuel-efficient, and delivered higher torque than the previous versions.
Externally, the vehicle retains the look of earlier Alter models, with fixed panels near the heater and handbrake area similar to the 1993 version. However, several structural changes were made: the chassis rails in the engine compartment were built from bent sheet metal, and the passenger-side footwell was narrowed. These modifications were necessary to accommodate the new 2.1L engine.
Additionally, the rear chassis crossmember was different from earlier versions. This change was likely intended to improve passenger access, as the step surface was wider.
Inside, the dashboard was completely redesigned using bent metal, giving it a more rugged and functional appearance. The transfer case and front axle engagement levers were also repositioned closer to the main gear shift lever.
All these changes are documented through images available in the gallery.
As of today, 21 known long wheelbase units exist in Portugal, and 5 short wheelbase units are known, three of which are located in France.
