Designed to relaunch the Fiat brand in rallies after the 124 Abarth, the 131 Abarth was developed during 1975; an experimental exemplar was entered in the 1975 Giro d'Italia. Homologated in Group 4, the car was based on the road going 131 Abarth, which had very little in the production car. The rally debut took place in a prototype version and from 1976 Fiat's commitment continued, the first win being clinched at the 1976 Elba Rally. After overcoming some problems related to suspension and gearbox, the car became very competitive and capable of playing with the Lancia Stratos and Ford Escorts. In 1977 Fiat clinched the first world rally title, which was followed by two more. The Fiat 131 Abarth Group 4 continued to run until 1982, with the works team and then with privateers, which subsequently switched to the new Lancia 037, homologated in Group B. The 131 Abarth remains an icon of the rally world; it was driven by many champions, such as Alen, Roehrl, Andruet, Verini, Bacchelli and so on.
The Solido brand is one of the most important in the history of car modeling. Ferdinand de Vazelles of Nanterre (France) began producing die-cast models under the Solido brand in the early 1930s. The first creation was a Gergovia candle on wheels. Until the 1950s, Solido models were equipped with wind-up motors. In 1957 Solido introduced the 100 series with detailed 1:43 scale models, featuring several new gimmicks such as suspension and opening parts. In addition to contemporary vehicles, classic cars from the "L'age d'or" series were also reproduced from 1964. In addition to French production, Solido models were also made in Spain (Dalia), Brazil (Brosol) and Argentina (Buby) in the 1960s and 1970s. In 1980 Solido was taken over by Majorette and numerous other changes of ownership followed. From the 1980s onwards, reissues of old Solido models were released under the Verem brand. After the closure of the Oulins factory in 2006, all Solido models were produced in China. After Solido was taken over by Ottomobile in 2015, the company focused primarily on 1:18 scale die-cast models and moved production to the factory in Bangladesh. Since 2023, Solido has started to seriously invest in 1:43 again with a range of low-cost but excellent quality models.
