Fiat 124 red: sport spider 1971

The Fiat 124 Sport Spider is a convertible sports car marketed by Fiat for model years 1966–1985. Designed by and manufactured at the Italian carrozzeria Pininfarina factory, the monocoque, front-engined, rear-drive Sport Spider debuted at the November 1966 Turin Auto Show with styling by Tom Tjaarda.

Fiat later marketed the car as the Spider 2000 (1979–1982). After being retired by Fiat, Pininfarina continued the production of the model under its own brand as Pininfarina Spider Azzurra for the North American market and Pininfarina Spidereuropa for the European market for three more years, from August 1982 until 1985.

In 2015, a successor of the Fiat 124 Spider was presented at the Los Angeles Auto Show.

The four-cylinder engine used in the spider and coupé is a double overhead cam, aluminum crossflow head version of the sedan’s pushrod unit. It started in 1966 with a capacity of 1438 cc, progressively increasing to 1608 cc in 1970 (although this was reduced to 1,592 cc in 1973), 1,756 cc in 1974, and finally 1,995 cc in 1979.

The Fiat Twin Cam engine was designed by ex-Ferrari engineer Aurelio Lampredi. Bosch fuel injection replaced the previously used Weber carburetors midway through 1980. In 1981 and 1982, Fiat USA, Inc. partnered with Legend Industries to create around 700 turbo models for US markets. A supercharged model called “Volumex” also was offered toward the end of production; it was sold only in Europe, where it cost 35% more than a regular, fuel-injected Spidereuropa.

This family of engines remained in production into the 1990s, giving it one of the longest production runs in automotive history. The double overhead cam (DOHC) version of the engine was the first mass manufactured DOHC to use reinforced-rubber timing belts, an innovation that came into nearly universal use in the decades after its introduction. Its derivatives powered race cars such as the Fiat 131 Mirafiori, 124 Special T, Lancia Beta Montecarlo, Delta Integrale, and many others.
