new engines, a 1.3 (1,350 cc) and an 1.5 (1,490 cc), both with a twin-choke carburettor. At the same time the Alfasud ti received cosmetic updates: bumpers from the Super, new rear spoiler on the boot lid, black wheel arch extensions and black front spoiler, and was upgraded to the revised interior of the Super. The 1.3 and 1.5 engines were soon made available alongside the 1.2 on the Giardinetta and Super, with a slightly lower output compared to the sport models, due to having a single-choke carburettor. In 1979 the Sprint was given a double twin-choke carburettor setup and became the Alfasud Sprint Veloce. 1980 facelift All Alfasuds were upgraded in 1980 with plastic bumpers, a new instrument panel, headlamps and rear lights, as well as other revisions. The Ti version was fitted with a twin-carburetor version of the 1490 cc engine that had been fitted to the Sprint the previous year, developing A three-door hatchback was added to the range in 1981 in either SC or Ti trim, and the two-door Ti and Giardinetta were deleted from most markets around that time. Belatedly, in 1982 the four-door cars were replaced by five-door versions, as by now, most of its competitors were producing a hatchback of that size, although some also produced a saloon alternative. The range was topped by the five-door Gold Cloverleaf, featuring the engine from the Ti and enhanced interior trim. In 1983 an attempt to keep pace with the hot hatchback market, the final version of the Alfasud Ti received a tuned 1490 cc engine developing 105 PS (77 kW). Named Quadrifoglio Verde (Green Cloverleaf), the model was also fitted with Michelin low-profile TRX tyres on metric rims (tyre size 190/55 VR 340 TRX) as well as an enhanced level of equipment. Rust The Alfasud became notorious for its propensity to rust, notably because of an assembly process that combined inferior recycled steel, and the factory's Pomigliano d'Arco location just 15 kilometers from the Bay of Naples. In one instance, early Bodies in White, ready for painting, were left outside the assembly building, in the naturally salty air. To inhibit rust, engineers called for filling all bodywork box-sections with synthetic foam, which was later discovered to hold moisture. End of production In 1983, the five-door Alfasud saloons were replaced by the 33 models. The 33 was an evolution of the Alfasud's floorpan and running gear,
