switched from chrome to black polyester, and the seats were restyled to provide more space in the rear seats. Model-specific changes included the available option of a five-speed gearbox on the TL; the GTL received an "economy-tune" version of the engine, as well as a five-speed gearbox, higher final drive ratio, electronic ignition and an "economizer" gauge. The TS and GTS version were discontinued. A two-litre model entered production, for export only until late 1983. A special edition, the R18 "American" arrived in 1983. Limited to 5,200 examples (1,500 in the UK), it had a special black over silver two-tone paint and numerous luxury equipment such as alloy road wheels and a plusher interior. It included the 1.6 L engine and sold well. An "American 2" version was introduced in 1984. Included were central locking, radio, and a choice of four colour schemes, with a total of 14,000 units (8,000 for France and 6,000 for the rest of Europe). The "Type 2" was introduced in April 1984. The grille was changed and all models gained a front air dam, while the saloons also received a standard rear spoiler. The three-stud wheel rims were replaced with the larger four-stud wheel rims (with the Base, TL, and TD just having center caps, and the GTL, Automatic, GTS, and GTD all having full wheel trims). The biggest difference was that the dashboard was replaced by that of the Fuego. The 2 L GTX model was introduced in France in the fall of 1983. Subsequent years saw fewer changes to the 18 line, in preparation for the launch of the Renault 21 early in 1986. For 1986, a limited range was sold as the "18 Gala" in France, with the Turbo model discontinued during 1985 (only about 650 Turbos were built that year). July 1986 marked the end for the R18 in France. Production continued in Latin America until 1994, however, and the R18 also continued to be manufactured in France with the 2 L petrol engine until 1989 for export only. Estate model By the late 1970s, European production of the Renault 12 was being gradually wound down, followed by the arrival of the estate versions of the Renault 18 on 1 March 1979. The R18 Estate ("Break" in French-speaking countries, Argentina, and some other markets) was only available in TL, LS, and TS model variations, except in Australia where all Australian-assembled Renault
