Haas is the first US-registered constructor to compete in F1 since the entirely unrelated Haas Lola, which was run by Indycar team owner Carl Haas with little success in 1985 and 1986.
Gene Haas founded his Nascar team in 2002, and then three-time champion Tony Stewart took a 50% share in 2009. The squad landed the Cup Series title in 2011 and 2014.
