Why does NASCAR still use carburetors?

NASCAR continues to use carburetors largely due to tradition and the desire to maintain a level playing field among teams. Carburetors offer a simpler, more mechanical approach to fuel delivery that many teams have mastered over the years. Additionally, the series aims to balance performance and cost, and the use of carburetors helps keep the technology accessible for teams with varying budgets. While fuel injection has become standard in many racing series, NASCAR's adherence to carburetors reflects its commitment to its historical roots and the specific racing characteristics that fans and teams appreciate.
