Annual sales in the United States pass the quarter-million mark. Nissan also establishes itself on the race-track: the BRE 510 wins the SCAA 2.5 liter Trans Am Championship in 1971, claiming Nissan's first professional racing championship. It proceeds to dominate the series, winning 15 out of 21 events. Meanwhile, another 510 wins the East African Safari, while yet another wins the American Rally Championship in 1971. Today, the 510 enjoys a cult-like following and is still active in SCAA club racing.
