Alfa Romeo 1900

Alfa Romeo 1900 SuperReleased in 1950, the 1900 was the first all new car after the war designed by Alfa Romeo. A relatively conventional three-box, four door saloon, it was powered by a new 1884cc twin cam engine with a cast iron block and an alloy cylinder head producing 80bhp. It was the first Alfa Romeo designed to be mass produced, and their first production car to be of monocoque construction, with no separate chassis.

The front suspension used double wishbones, coil springs and hydraulic telescopic dampers, whilst at the rear a solid axle was located by two arms meeting above the differential together with coil springs and telescopic dampers.

Production initially began at a slow rate as the war damage was repaired and normality returned, but 1951 saw 1,220 saloons being built. That year also saw the introduction of the 1900 TI which received an engine with larger valves, a slightly higher compression ratio and a double choke carburettor giving 100bhp.

1900 Super Sprint This engine was fitted to a shortened wheelbase chassis which was made available to numerous coachbuilders and known as the 1900 Sprint. The resulting cars included coupes and cabriolets by companies such as Zagato, Touring, Pininfarina, Stabilimento Farina, Boano, Ghia, Bertone and others.

In 1953 the 1900 Super and 1900 TI Super (also the 1900 Super Sprint) were released. These featured numerous modifications, including various detail improvements such as additional chrome trim, and more significantly an engine with a larger capacity of 1975cc (achieved by increasing the bore). In the standard saloon this produced the same 90bhp, but in the TI Super this engine, which also featured two double choke carburettors, an increased compression ratio and a revised exhaust manifold, produced 115bhp.

Another variant of the 1900 worth mentioning (since over 2,000 were built) was the 1900M, AR51 or 'Matta'. This was a four wheel drive Jeep-like vehicle designed for the Italian armed forces which used a detuned 1900 engine producing 65bhp. The suspension used torsion bars at the front and leaf springs at the rear and it was fitted with a limited slip differential at the rear, to which the drive was permanent, whilst the drive to the front was selectable manually (drivetrain). A few civilian versions were produced as the AR52.

A special version of the saloon was also produced for the Italian police force. Known as the 'Pantera' it had numerous modifications including a two piece bulletproof windscreen, small armoured skirts in front of the front wheels, an openable roof above the rear seats, stronger suspension, ti engine, extra communications equipment and an all black paint finish (hence the name).

Numerous coupes were produced by the various companies listed above, the majority being by Touring, Zagato and Pininfarina, the latter also producing a cabriolet. Some of the better known versions made in smaller numbers by various coachbuilders included a long wheelbase 'limousine' version, the 1900 Super 'Lunga', 92 constructed by Colli and the Granluce Primavera two door coupe (with lines similar to the saloon), 300 built by Boano. There was also the Gazzella by Boneschi, a five-seat, two-door version. For motorsport there was also built the C52 'Disco Volante', whilst for aerodynamic research Bertone produced the BAT cars. The 2000 Sportiva was a distant relative to the 1900.

Alfa Romeo 1900m / AR51 Matta Production of the 1900 continued until 1959 by which time a total of 21,304 had been built. The breakdown was as follows (plus the 91 Lunga and 300 Primavera mentioned above) :
1900 7,611
1900 Super 8,282
1900 Sprint 949
1900 Super Sprint 854
1900 TI 572
1900 TI Super 478
1900M AR51 2,050
1900M AR52 155
