History

The AR 51 (Autovettura da Ricognizione, "Reconnaissance Car") was the result of the request of a light reconnaissance vehicle for use on paved, unpaved and mountain roads. A civilian version, the AR 52, was later developed from the military AR 51; several variants were made, adapted for use in agriculture, firefighting, and road maintenance.

The Matta was built from 1952 to 1954, with 2,007 military AR 51s for the Italian Army and 154 civilian AR 52 units produced. In 1954, the Italian army abandoned the AR 51 and switched to the Fiat Campagnola, which was mechanically simpler.

Specifications

The Matta was powered by a 1884 cc twin cam, 8-valve inline-four engine with dry sump lubrication. The cylinder head was aluminium and featured hemispherical combustion chambers, while the engine block was cast iron.[2] Output was 65 PS (48 kW; 64 hp) at 4,400 rpm.[2]

[de] Alfa Romeo Matta

Die Matta war ein allradgetriebener Geländewagen der Firma Alfa Romeo. Der offizielle Name lautete 1900 M mit den beiden Versionen AR 51 für die militärische und AR 52 für die zivile Ausführung, wobei sich die beiden Modelle jedoch kaum unterschieden. Die Abkürzung AR stand nicht für Alfa Romeo, sondern für Autovetture da Ricognizione (deutsch: Spähwagen). Der Name Matta heißt auf italienisch „die Irre“. Dieser Name wurde dem Wagen erst später vom Markt gegeben.
