GB4 is a single-seater sprint championship for drivers graduating from karting and club racing, based in the United Kingdom and operated by MotorSport Vision with BRDC backing. The field is entry-level professional in calibre, drawing drivers from American and British junior formulae and rising through SCCA regional competition; its ratings sit between the weaker feeder series and the stronger junior championships. Lewis Wherrell, Isaac Phelps and Leon Wilson are its leading competitors. Most of its drivers move up to GB3 or British F4, while some progress toward endurance racing via Le Mans Cup or transition to British GT. It functions as a stepping stone in the junior single-seater pipeline, with drivers flowing both upward into higher formulae and laterally into sportscar categories.
