This week, ANSA Motorsports returns to the 2015 Porsche GT3 Cup Challenge USA by Yokohama, where the team won the 2012 and 2014 Gold Cup class Team and Driver championships. ANSA Motorsports will compete in its second 2015 Porsche GT3 Cup Challenge USA by Yokohama event of the year with an 18-year-old driver from Miami, Fla.: Dore Chaponick Jr. Chaponick will drive the No. 79 ANSA Motorsports 2015 Porsche GT3 Cup in the two 45-minute rounds 13 and 14 of the 2015 Porsche GT3 Cup Challenge USA by Yokohama, scheduled this week, at Circuit of the Americas in Austin, Texas. This will mark Chaponick’s second race weekend with ANSA Motorsports and his second event in the Porsche GT3 Cup Challenge USA by Yokohama. This time, Chaponick will move up from the Gold to the Platinum class and will have a competitive car to race against the best drivers of that series for the overall win. ANSA Motorsports will use its Porsche GT3 Cup that just finished third in the overall GT3 Cup class of the 2015 World Challenge, with driver Lorenzo Trefethen behind the wheel. “We are very pleased to welcome Dore Chaponick Jr. a second time to race in one of the most competitive series in the world, the Porsche GT3 Cup Challenge USA by Yokohama,” said ANSA Motorsports Team Owner Alain Nadal. “Chaponick has a lot of talent, and moving from the Gold to Platinum class will allow him to race in a more competitive and faster car and enjoy the competition with the top drivers even more.” Chaponick finished sixth in his first-ever Porsche GT3 Cup Challenge USA at Road America and fifth in his second race in the Gold Cup class at Road America in August. The young American driver is looking to show his real potential this week at COTA. “I am extremely humble to be a part of ANSA Motorsports. My expectations were blown away, as I was asked by ANSA Motorsports' owner, Alain Nadal, to go and race in the Porsche GT3 Cup Challenge USA at Circuit of the Americas. It's one of my favorite circuits; it's the home to Formula 1,” said Chaponick. “I expect a thrilling experience at COTA, as it’s a world-class facility, with the most prestigious racing events in the world. I am very excited, and best of all, I will be able to take home a memorable momentum from this race!” The Porsche GT3 Cup Challenge USA by Yokohama Road America event starts today at Circuit of the Americas with two practice sessions scheduled at 11:45 a.m. and 2:25 p.m. Qualifying is set for Thursday, Sept. 17, at 8 a.m., and race 1 (45 minutes) also on Thursday at 12:30 p.m. Race 2 (45 minutes) is set for 7 p.m. on Friday, Sept. 18 (all CDT times).
