The 2018 Formula STCC Nordic season was the sixth season of the single-seater championship supporting the Scandinavian Touring Car Championship. The series uses the previous Formula Renault 1.6 chassis and engines, as it used to go under the name of Formula Renault 1.6 Nordic before Renault Sport dropped its support for the 3.5 and 1.6 classes in late 2015. The season began on 4 May at Ring Knutstorp and concluded on 22 September at Mantorp Park after six double-header rounds.[1]
