Motorsport — F1, NASCAR, IndyCar and endurance racing

American motorsport is uniquely split: NASCAR's ovals, IndyCar's mix of ovals and road courses, F1's recent US boom after Drive to Survive, plus endurance racing at Daytona, Sebring and Le Mans. F1 added Miami, Austin and Las Vegas to the calendar, NASCAR keeps its Southern roots while expanding, and the Indy 500 remains the biggest single-day sporting event in America. Technical regulations differ wildly — spec cars in NASCAR versus development wars in F1 — but all reward driver skill and team execution. British racing heritage runs deep in F1 engineering, with seven of ten teams based in England. British Racing Heritage covers that story in depth.
