context_section_description: Aschenbach began racing professionally in the SPEED World Challenge (later Pirelli World Challenge) in 2005 and had a podium finish in his first GT race. In 2006, during his first full SPEED World Challenge GT season, Aschenbach won at the Grand Prix of St. Petersburg and placed second at both Mid-Ohio Sports Car Course and Road America. He never finished lower than ninth that season, and became the first driver to win the SPEED GT Championship in his rookie season. That year Porsche won the SPEED GT Manufacturers’ Championship over second-place Dodge by three points. Aschenbach began driving for Team Cadillac during the 2007 SPEED World Championship GT season and finished the season ranked third. That year Aschenbach and teammate Andy Pilgrim led Team Cadillac to the SPEED GT Manufacturers’ Championship.
  In 2010 Aschenbach and co-pilot David Thilenius won the Grand-Am Continental Tire Sports Car Challenge (later IMSA Continental Tire Sports Car Challenge) ST Championship with team Compass360. The championship was decided on the final day of racing, with Lawson and David winning the overall championship via tiebreaker. Aschenbach and Compass360 won the subsequent tiebreaker with their third-place finish at Miller Motorsports Park.
  Aschenbach won the 2011 Pirelli World Challenge Touring Car Championship while piloting a Honda Civic Si for Team Compass360. He won five races and poles that season, and led Honda to the Pirelli World Challenge Touring Car Manufacturers’ Championship. Aschenbach clinched the championship in the second-to-last race that year and finished the season with 1,543 points.
  Aschenbach later joined Blackdog Speed Shop and piloted the team’s Chevrolet Camaro to the 2013 Pirelli World Challenge GTS Championship in what was his first season in the division. Aschenbach scored his first win that season in what was only his second weekend with Blackdog. He won a class-best six races that season, but trailed Jack Baldwin until the last race of the season held at Grand Prix of Houston. Aschenbach’s win at Houston secured the overall championship.
  Aschenbach repeated as Pirelli World Challenge GTS Champion in 2014 in his second season driving for Blackdog Speed Shop. He clinched the championship during the final race day of the year, which was held at Miller Motorsports Park. In the first race of a doubleheader at the track, Aschenbach placed fourth and moved within to two points of the overall lead.  His second-place finish in the final race of the season secured for him the overall GTS championship.  Aschenbach finished the season with four wins overall.  Later that year, he won the 2014 Lamborghini Super Trofeo ProAm World Championship at the Sepang Circuit with co-pilot Kevin Conway and Change Racing.
