Zero late fees to register at the track for OK-N

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.

NAMPA, ID (October 13, 2022) – The kick-off to the 16th season for Challenge of the Americas action is just over three months away and series promoter Andy Seesemann is excited to announce a planned evolution to the program’s class structure, highlighted by the introduction of the OK-N category, the FIA Karting’s newest formula. In addition, one of the West’s longest-running series will be offering the ROK Shifter Junior class in 2023. In the past, Junior gearbox racing has developed many professional drivers, but it is not currently offered anywhere in the United States. The Junior shifter class will utilize the ROK Shifter engine with a restricted header as more class specifics will be announced at a later time. These two categories will be part of a condensed eight-class program as a four of weakly-supported classes from 2022 will be dropped from the line-up. Continue reading

NAMPA, ID (September 21, 2022) – The locations have been confirmed for the upcoming 16th season for Challenge of the Americas program, beginning in February 2023.
