OK-N Class Debuts in Tucson for COTA 2023

Our 2023 Challenge of the Americas Tucson event will be the very first OK-N race in history, and we realize we will have to adapt and make a few concessions. We understand that some potential racers are still procuring engines to be able to race. Therefore, we are suspending the late fee for OK-N entries. If you are waiting for an engine and will be a last-minute entry, it is OK. We recognize that supply is growing and sometimes lagging. So, you may enter at the event with no penalty. Yes, zero $250 late fee for all OK-N entries who register at the event in Tucson.

In addition, we understand that the OK-N class will grow exponentially over the course of the Challenge of the Americas, with more drivers entering as the series progresses. Therefore, this first weekend will be treated as a stand-alone event, outside of any championship per se. Should the engine situation become more stable, we will start a “championship” in Phoenix.

OK-N class will be open to all homologated engines.
