The Alfa Romeo 1750/2000 is a range of medium-priced cars which was produced by Alfa Romeo from 1967 to 1977.
The 1750 Berlina sedan was introduced in 1967, together with the 1750 GTV coupe and 2000 Spider. The 1750 models replaced the earlier 2600 Berlina, Sprint and Spider at the top of the Alfa Romeo range. In contrast to the 2600s, the 1750s were smaller and much less expensive, shared many parts with other concurrent models in the Alfa Romeo range, and sold many more units during their production span.
The 1750 Berlina was based on the existing Giulia sedan, which continued in production. The 1750 was meant to top the sedan range, above the 1,300 cc and 1,600 cc versions of the Giulia. In the United States, however, the Giulia sedan ceased to be available and was entirely replaced by the 1750 Berlina.
The 1750 bodyshell had a longer wheelbase than the Giulia, and revised external panels, but it shared many of the same internal panels. The windscreen was also the same. The revisions were carried out by Bertone, and while it resembled the Giulia some of that vehicle's distinctive creases were smoothed out, and there were significant changes to the trim details. The car's taillights were later used on the De Tomaso Longchamp.
The car has a 1,779 cc twin-carb engine and hydraulic clutch. The 1.8 L engine produced 118 PS (87 kW; 116 hp) with two twin sidedraught carburettors. For the US market the 1750 was equipped with SPICA fuel injection.
In 1971, the 1750 Berlina was fitted with an experimental three-speed ZF automatic gearbox. The model designation was 1750A Berlina. About 249 units were produced with very few surviving to this day. Some of 1750A Berlina didn't have the model plate with production date embossed. The automatic gearbox wasn't well-suited to the four-cylinder motor due to baulky shifting and ill-chosen gear ratio. Because of this, its fuel consumption was frighteningly high and acceleration was a bit too slow.
In mid 1971 the 1750 series was replaced with the 2000 series.
2000 series Berlina was made by Alfa Romeo between 1971-1977. The engine was bored and stroked out to 1,962 cc. A different grill distinguishes 2000 from 1750. Also, external lights were different between the models. The 1750 had 7 inch diameter outboard headlights, whereas the 2000 had 5 3/4 inch diameter in all four positions. The tail light clusters were also of a simpler design on the 1750. With two carburetors, this 2 liter Alfa Romeo Twin Cam engine produces 132 PS (97 kW; 130 hp). Top speed was 200 km/h (124 mph) and 0-100 km/h (62 mph) acceleration took 9 seconds. In USA this engine was equipped with mechanical fuel injection. Gearbox was 5-speed manual (also 3-speed automatic on some versions). The 2000 Berlina was produced in 89,840 examples with 2.200 units fitted with automatic gearboxes.
