2022 Pro-Am champions Mario Farnbacher and Ashton Harrison are set to reunite with Racers Edge Motorsports with WTRAndretti to pilot the No. 93 Harrison Contracting Acura NSX GT3 Evo22 in Fanatec GT World Challenge America powered by AWS for the 2023 season. The duo, who earned the Pro-Am title last year with 4 wins on the season, will step up to the Pro class for the seven events on the race calendar. Harrison Contracting Company will once again sponsor the team, with the company’s trademark Rely on Red livery carrying the #93 in homage to Acura Motorsports and HPD.


“The Harrison Contracting Company Team and I are excited about another year together with the SRO series,” enthused Bill Harrison, President, Harrison Contracting Company. ”Ashton, Mario, and the entire Racers Edge Motorsports with WTRAndretti team set the bar at a very high level last year. But that was yesterday and now we need to focus on the 2023 season with two simple words, ‘Go, win’!”


In a partnership with Wayne Taylor Racing with Andretti Autosport, Racers Edge Motorsports, who also operates the Honda Performance Development (HPD) Driver Academy, returns to GT World Challenge America, where the team has captured a GT3 title in three of the last four years, also earning the Driver Championship in 2019, 2020, and 2022.


With her move to the Pro class this year, Ashton Harrison has steadily progressed through the ranks of GT3 sportscar racing. Almost immediately following her graduation from the HPD Academy in 2021, she became the first woman to win overall in SRO GT World Challenge America in her debut at Indianapolis Motor Speedway. Having developed a unique relationship from their Academy connection, Harrison and Farnbacher earned a podium in their first GT World Challenge America weekend together at Sonoma Raceway, following up with a podium and a win at NOLA Motorsports Park. The duo earned a series-high four wins on the season, with four additional podiums, enroute to claiming the Pro-Am Driver and Team Championships. Harrison became the first female to win an SRO GT World Challenge title worldwide, in any class of the series and was also named Rookie of The Year in 2022.


Mario Farnbacher has compiled an extensive resume as an elite sportscar driver, including winning back-to-back IMSA GTD Championships during his five years behind the wheel of the Acura NSX GT3 in addition to his 2022 SRO title. As a Honda Racing/HPD factory driver, Farnbacher contributed to Acura Motorsports’ success in 2022, including a podium the Acura Grand Prix of Long Beach and victory at Motul Petit Le Mans.


The 2023 Fanatec GT World Challenge America powered by AWS begins March 31-April 2, at Sonoma Raceway. Each of the seven weekend events consists of two-90 minute races, with two drivers sharing designated time in the car. The season will culminate at Indianapolis Motor Speedway as part of the IGTC Indy 8Hr race.
