The Formel 3 Cup has bucked this trend to become one of the most eclectic F3 championships in the world, with some of the variety that F3 enjoyed in the 1970s. In addition to the ubiquitous Dallaras, the Lola "B06/30" and the "SLC R1" from Signature have established a foothold. The SLC, which was the Signature team's first foray into chassis construction, had previously competed in the F3 Euroseries in 2005, but Signature chose not to continue using it. The Lola, which was developed after the British company's collaboration with Dome came to an end, has otherwise had only limited use in British F3 during 2006. Swiss Racing Team had provisionally lodged two entries for a pair of Mygale M06/F3 chassis in addition to a single Dallara entry. Before the start of the season, however, it had changed its line-up to four Dallaras, one of which was later replaced during the season with an SLC R1.
