EKN Trackside: 2016 Challenge of the Americas – Tucson Preview – Part 2
Talented fields for Senior and Masters divisions in both Rotax and Shifter competition
The ninth edition of the Challenge of the Americas is set to begin this weekend as racers from across North America converge on the Musselman Honda Circuit in Tucson, Arizona. Serving as the ‘premier winter karting series on the left coast’, a new era begins for the program set to contest three race weekends in a six-round championship format. Five Rotax categories will be joined two shifterkart divisions joining the series for the first time, expanding the reach and possible future growth of the series.
The Musselman Honda Circuit is among the most-challenging tracks in North America. The layout is a replica of the Suzuka circuit in Japan at 3/4-mile long and 12 turns, all with their own unique characteristics. The Challenge visited the Tucson circuit in 2012, and has returned every year since to open up each championship chase.
Three of the Challenge series champions will have the prize like no other. Each year, the Challenge of the Americas has presented tickets to the elusive Rotax Max Challenge Grand Finals. This year, three drivers will earn a spot to compete at the ‘Olympics of Karting’ in 2016 while representing the Challenge and their respective countries. Those drivers to earn the most points in the six-round championship chase for Senior, Junior and Masters Max will earn a spot at the October 16-22 at the Circuito Internazionale di Napoli in Sarno, Italy near Naples.
For those who are unable to attend the Challenge of the Americas opening weekend, eKartingNews.com will be providing their ‘Trackside Live’ coverage for a fourth straight season.

Four points separated the top two drivers in the 2015 Challenge of the Americas Senior Max championship chase. Five different drivers stood on top of the podium at the six rounds, but it was the driver with the most podium finishes and better performances overall from qualifying and the Prefinal that locked up the championship for Luke Selliken. The RPG / Kosmic driver drove his way to the title, edging out Senior rookie Christian Brooks by one position in the Final race. Selliken earned the Rotax Grand Finals ticket that is awarded to the series champion, and drove to a runner-up finish at the world championship, recording the best result by a Team USA Senior Max driver in the history of the event.
Fast forward 10 months, and a new Challenge is set to begin with the defending champion on the sideline. Selliken is not committed to compete in Tucson, and may be on the fences watching instead of trying to fight his way to the front. Brooks is more than ready to take on all challengers once again. During his rookie season, Christian stood on the podium in five of the six races, including a victory in Phoenix. The 2012 Challenge of the Americas Mini Max champion has changed colors for 2016, remaining with Nash Motorsportz but is now piloting a CRG machine, making up half of the karts that are non-OTK manufactured set to compete in Tucson.
The always fast Mason Marotta is returning once again, still looking for the elusive Challenge championship. Marotta led the way in the win column last year, however, was also part of the fuel situation in Sonoma which dropped him to fourth in the championship standings. Mason returns with Ryan Perry Motorsport aboard a Tony Kart. Senior sophomores Phillipppe Denes (Ryan Perry Motorsport/OTK) and Walker Hess (Rolison Performance Group/Tony Kart) finished inside the top-10 of the standings last year, and are among the only returning contenders from a year ago. Jim McKinney is a new Rolison Performance Group recruit as the Arizona driver has the speed to contend for podium finishes.
This year’s class of Senior rookies include some stout drivers. Indiana driver Zach Holden is making his Challenge debut this weekend, joining Koene USA. The Tony Kart driver made his Senior Max debut at the FWT last weekend, having never raced Rotax-powered kart prior. Kellen Ritter stepped up last year in Junior Max to contend for victories, earning his first two series podiums in 2015. Ritter moves up to Senior, joining the powerful Rolison Performance Group operation. The Breidinger sisters Annie and Toni (VRP Racing/Kosmic) are moving up to the Senior level as well. Both have grown year after year behind the wheel, posting their best finishes in their final year at the Junior level.

Cambrian Go Karts Masters Max

Throughout the history of the Challenge of the Americas, the Masters Max category has always seen the best racing and top Masters drivers in the country competing year after year for the championship. The level of competition stepped up last year with the addition of the Rotax Max Challenge Grand Finals ticket up for grabs to the series champion. Last year, that honor went to veteran Paul Bonilla who made his first ever start at the ‘Olympics of Karting’.
This year’s view for Bonilla of the championship chase will be different, as the two-time series champ will be watching from the fence line as a mechanic for the Full Throttle Karting operation, fielding three drivers. One of them is his rival from 2015, John Crow. With one victory and three runner-up finishes, Crow kept Bonilla honest and came up 16 points short of the championship. The 2009 series champion is looking to become the third different two-time title winner, with Bonilla and Donald Durbin Jr. (2013-2014) on that list.
Another possible two-time champ on the horizon is Scott Falcone. The 2011 title winner finished the 2015 Challenge as the driver on top, winning the final two rounds in convincing fashion. Last year was his debut with Rolison Performance Group aboard a Kosmic, and everything came together at the series finale. Now with a year under his belt, Falcone should be challenging off the trailer in Tucson. Other returning contenders include John Breidinger (VRP Racing / OTK), Chad Wallace (BirelART), and Perry Needham (CRG).
Notable names making a return to the Challenge, and are among the potential podium challengers. Veteran racer Billy Cleavelin contested the series finale and it ready to fight for the championship, joining the Rolison Performance Group to pilot one of their Kosmic machines. Mike Jones is a DD2 Masters national champion and former Team USA member. The Dallas Karting Complex driver is joining the fight in Masters aboard a Sodi Kart. Diego Pelosi last competed at the Challenge in 2013, earning two victories in Tucson. The Ryan Perry Motorsport / Tony Kart driver is always fast. FTK driver David Pergande (Tony Kart) returns, with Karting Coach co-owner Mike Weatherman (Zanardi) strapping on the helmet to contest the Tucson weekend.

Energy Kart USA Shifter Senior

New to Challenge of the Americas is the shifterkart divisions. Replacing DD2, Shifter Senior is stacked with talent for its debut in Tucson, featuring former DD2 drivers and top shifterkart drivers in the country. Two of the top US Open drivers from the Elite category are competing in Tucson. 2015 DD2 Challenge of the Americas champion Sabre Cook (Energy USA) finished third in the inaugural US Open championship while Jake French (Dallas Karting Complex / Sodi Kart) was runner-up at the series finale in Las Vegas.
His teammate Nathan Adds captured the US Rotax Grand National victory in 2015, and has steadily grown as a shifterkart pilot over the last few seasons. Pure Karting’s Kolton Griffin and Don Whittington are among the top-25 in the EKN Stock Moto Driver Rankings. Griffin (Tony Kart) finished 2015 ranked fourth with Whittington (Tony Kart) in 23rd. Jacob Neal (VRP Racing / Tony Kart) is a familiar face on the national stage, making a recent comeback to the driver’s seat over the past year in shifterkart competition. Lawson Nagel (Dallas Karting Complex / Sodi Kart) is making the jump from Junior level to Senior level competition.

Dallas Karting Complex Shifter Masters

What the Shifter Masters field lacks in numbers, it makes up for in caliber of drivers. The five registered are among the best in the Masters ranks, including US Open inaugural champion Ryan Kinnear. The Champion Racing / Intrepid driver won the opener in Dallas, and finished runner-up the last two rounds to clinch the title. This will be his first Challenge of the Americas event, along with the others making the Shifter Masters debut.
Darren Elliott is synonymous with shifterkart racing, and the California native is set to add more hardware to his mantel. A Driver of the Year recipient in the late 90s by Shifter Kart Illustrated, Elliott has been reborn with a return to the sport and racing in the Masters division. The Nash Motorsportz / CRG driver swept in his only US Open start at Grand Junction, and is among the top shifterkart pilots of all time.
A trio of Arizona drivers round out the field, all competing on the successful DR Kart from DRT Racing. Nick Firestone is another successful Masters driver, finishing among the top-three a few years ago on the national scene. Jason Campbell and Joe di Vito join him and will be in the fight for the podium all weekend.
