One the projects that came closest to fruition that decade was a sports racer destined for the popular under-1500 cc class. The stillborn racer was dubbed the 750 Competizione and two prototypes were actually built.

The 750 in the type name was a reference to the recently introduced Giulietta road car, which was known internally as the '750'. The sports racer was based very loosely on the Giulietta but most of the important components were either heavily modified or purpose-built. The chassis and body fell under the latter and were actually built by Abarth and Boano respectively. Serving mainly as external contractors, the two companies did follow the designs as laid down by Alfa Romeo.

Judging from the sophisticated chassis design, the 750 Competizione was certainly a serious project. The car used a boxed pressed steel platform chassis, which together with the sheet steel body formed a unitary construction. Considering the chassis type used, it was no surprise Abarth was called in to help with production as most of that company's cars also featured steel platform chassis. Carried over from the Giulietta, suspension was by double wishbones at the front and a live axle at the rear.

While Abarth built the chassis, the Alfa Romeo engineers focused on the design of the engine. This was a four cylinder based on the engine found in the Giulietta. For its new purpose, it received a slightly wider bore and a considerably longer stroke. As a result, the displacement increased from 1290 cc to 1488 cc. Breathing through two twin-choke Weber carburettors, the small 'four' produced an impressive 145 bhp at 8000 rpm. It was mated to a five speed gearbox.

Boano completed the 750 Competizione with a striking 'Spider' body that was distinctly different from all Alfa Romeos that came before or since. Somewhat similar to the designs Boano did for Abarth, the design included fenders with pronounced leading edges, particularly on the front of the car. Another typical Boano design element was the exposed exhaust that exited just behind front left wheel and ran parallel with the sill. The only real cue that the car was in fact an Alfa Romeo was the grille centre section.

As mentioned above, two prototypes were built. They were subjected to extensive tests but never raced before the project was axed. Among the reasons for this drastic decision were teething problems during testing, the success of the production based Alfa Romeos on the track and the company's determination to continue its focus on mass-produced models. Both examples have survived and at least one is in full running order.
