The Pirelli World Challenge heads back to Wisconsin June 26-28, as the series returns to Elkhart Lake's legendary, 4-mile, 14-turn Road America. The championship has already reached the halfway mark, and nine rounds are still to be raced in the GT-Cup class. ANSA Motorsports and driver Lorenzo Trefethen will race together this weekend at Road America in Wisconsin. After nine races, Trefethen, driving the No. 13 Trefethen Family Vineyards/750 Group/BRM Chronographes Porsche, sits second in points in the 2015 Pirelli World Challenge GT-Cup Driver Championship. Trefethen triumphed May 17 in the last race at Canadian Tire Motorsport Park in Ontario. He is taking his great momentum with him to Wisconsin and dreaming of another podium finish. Trefethen traveled to China, earlier this month, to promote the Trefethen Family Vineyards and is back and eager to start practicing on Thursday. "I've enjoyed the mid-season break since Mosport - had time for my first real walks through the vineyard this year - but I can't wait to jump back behind the wheel at Road America and attack the second half of the championship,” Trefethen said. “I'm hungrier than ever after my first taste of victory up in Canada, and Road America will be the first track this season that I have any experience with. I raced there for the first time last year, and absolutely loved it. Turn 1 and The Kink were my favorite corners - here we come!" Alain Nadal and his crew are ready for this new challenge at Road America. “We have been very excited following our first Pirelli World Challenge win,” Nadal said, referring to Trefethen’s CTMP victory. “We need to continue to race on top in the GT-Cup to make sure Lorenzo finishes on the podium in the next nine rounds of the season.” Since last month’s win in Canada, ANSA Motorsports team owner, Alain Nadal, made additional exciting news by announcing its REITER Engineering dealership. ANSA Motorsports is now selling the REITER Engineering Lamborghini Gallardo EXTENSO (aka R-EX), the SaReNi Camaro GT3 and the KTM X-BOW GT4 racecar. Trefethen and the Pirelli World Challenge competitors will be on track at Road America Thursday, June 25, for a promoter test day. The first race at Road America was held 60 years ago. In 1955, the SCCA granted a sanction for an SCCA National, the highest form of road racing in the country at the time, held Sept. 10 and 11. The feature, a 148-mile race for the era’s large sports racing cars, became a duel between two men and their cars. Sherwood Johnston, one of the country’s best drivers, was driving a semi-works D Jaguar for the Briggs Cunningham team. Phil Hill, a rising racing star on the west coast, who became the first American F1 World Champion in 1961, took to the track in a Ferrari Monza. For 37 laps, Johnston and Hill were inseparable, but then began to fight for the lead, during the last six laps. As they approached the finish line on the last lap, Hill inched ahead and barely won the race. Hill’s average speed was 80.2 mph. Today, Road America is one of the most popular tracks in the country, and nearly all drivers want to put their names on the history book there. The Road America event will start with a practice session on Thursday, June 25, at 3:35 p.m. EDT. Qualifying is set for Friday, June 26, at 10:00 a.m. EDT. Race 1 at Road America is scheduled for Saturday, June 27, at 1:15 p.m. EDT and race 2 on Sunday, June 28, at 2:25 p.m. EDT.
