UMM Alter II

UMM Alter II Phase I

In 1986 the Alter II was released by the Portuguese automobile manufacturer União Metalo-Mecânica (UMM). It featured a new 4-speed manual gearbox, a new transfer case and a new suspension. The engine remained the same 2.5-litre diesel engine which developed 76 PS. Although it was a new model it was very similar to the previous one and very difficult to distinguish.
