The Lucas Oil Formula Car Race Series runs formula cars in sprint racing, split into a Championship class and a Masters division. The Championship attracts established amateur drivers and a handful of early-career professionals, holding its own against peer regional racing while sitting well below the strength of US F4, which serves as a natural step upward; the Masters field is considerably weaker. Drivers like Landon Brown and Jack Mitchell lead a roster that feeds from the SKUSA SuperNationals and regional club racing and predominantly moves into SCCA Majors and SCCA Regionals, where the field is marginally lighter and more evenly distributed across amateur grades. Some competitors progress to the stronger IMSA Pilot Challenge or climb into US F4.
