November 1973 the first Alfasud sport model joined the range, the two-door Alfasud ti—(Turismo Internazionale, or Touring International). Along with a 5-speed gearbox, it featured a more powerful version of the 1.2 litre engine, brought to by adopting a Weber twin-choke carburettor, allowing the small saloon to reach . Quad round halogen headlamps, special wheels, a front body-colour spoiler beneath the bumper and rear black one around the tail distinguished the "ti", while inside there was a three-spoke steering wheel, auxiliary gauges, leatherette/cloth seats, and carpets in place of rubber mats. In 1974, Alfa Romeo launched a more upscale model, the Alfasud SE. The SE was replaced by the Alfasud L (Lusso) model introduced at the Bruxelles Motor Show in January 1975. Recognizable by its bumper overriders and chrome strips on the door sills and on the tail, the Lusso was better appointed than the standard Alfasud (which was now called "normale"), with such features as cloth upholstery, headrests, padded dashboard with glove compartment and optional tachometer. A three-door estate model called the Alfasud Giardinetta was introduced in May 1975, with the same equipment of the Alfasud "L". The Lusso model was produced until 1976, and was then replaced by the new Alfasud 5m (5 marce, five speed) model, the first four-door Alfasud with a five-speed gearbox. Presented at the March 1976 Geneva Motor Show, it was equipped like the Lusso it replaced. In September 1976, the Alfasud Sprint coupé was launched. Built on the same platform of the saloon, it featured lower, more angular bodywork, again by Giorgetto Giugiaro, and featured a hatchback. The Sprint was powered by a new, more powerful Boxer, stroked from the 1.2 to displace and develop , and was paired the five-speed gearbox. The same 1286 cc engine was later fitted into the 2-door saloon, creating the Alfasud ti 1.3, which was put on sale alongside the "ti" 1.2 in July 1977. 1978 revisions In late 1977 the Alfasud Super replaced the range-topping four-door "5m". It was available with both the 1.2- and 1.3-litre engines from the "ti", though both were equipped with a single-choke carburettor. The Super introduced improvements both outside, with new bumpers including large plastic strips, and inside, with a revised dashboard, new door cards and the choice of either Alfatex (vinyl) or two-tone cloth seats. Similar upgrades were applied to the Giardinetta. In May 1978 the Sprint and "ti" got
