The final round of the Challenge of the Americas (COA) will take place at Simraceway Performance Karting Center in Sonoma, California April 1st to the 3rd. With the points championship coming down to the wire and invites to Team USA for this year’s Rotax MAX Challenge Grand Finals in Italy, the weekend promises to be some of the best wheel-to-wheel action of the season.

This year, the race will be run in the reverse national layout. This is the opposite of how it has been run in the past. The United States Rotax MAX Challenge Grand Nationals will also be run in the reverse layout, and this will be one of the teams and drivers only chances to run the track configuration before the upcoming national event weekend.

“After running the national layout for so many years, we have decided to do something different for 2016,” said series promoter Andy Seesemann. “We will be running the reverse national layout for the 2016 Challenge of the Americas finale in April. I have spoken with many drivers that have told me that the reverse national layout may be more fun than the standard direction, so I have decided to switch it up this year. After meeting with Garett Potter up in Sonoma last month, he has also decided to run this layout for the United States Rotax Grand Nationals later this year. This will give competitors two big races on this layout and a new challenge for Rotax racers in the Challenge of the Americas and the US Nationals.”
