The article discusses the best non-American driver in the history of IndyCar racing. The author looks at four drivers: Emerson Fittipaldi, Alex Zanardi, Dario Franchitti, and Juan Pablo Montoya. Each driver has won multiple championships in the series, but Franchitti stands out as the best non-American driver due to his four IndyCar titles and three Indianapolis 500 victories. He is also the only driver to have won the IndyCar Series and Champ Car World Series titles. Franchitti's dominance in the sport, both in terms of titles and wins, make him the clear choice for the best non-American driver in IndyCar history.
