Turner Motorsport is one of the largest BMWperformance tuning facilities in North America. Turner Motorsport also runs a production car racing team located in Amesbury, Massachusetts, and is the second most prolific BMW privateer racing team in the world, second only to Schnitzer Motorsport, who run factory BMW DTM cars in Europe. Turner motorsport has exclusively raced BMW models professionally since 1998, including the BMW 3 Series, BMW M3 coupes, and the M6 in the IMSA Continental Tire Sports Car Challenge. Previously, the team was highly successful in the Speed World Challenge Touring Car series. In 2015 the company was split up with the parts and accessories business sold to ECS Tuning of Wadsworth, OH. Only sales staff remain at the original office in Massachusetts. The service and racing divisions continue to operate from Massachusetts as well but are independent from ECS. Turner Motorsport won the 2003 and 2004 Speed World Challenge Touring Car Championships, breaking an eight-year Honda / Acura domination of the series. After winning the championship the second consecutive time, Turner Motorsport left World Challenge to race in the 2005 Grand-Am Cup series. Turner Motorsport won both the 2006 Grand Am Cup GS and ST Driver and Team Championships and the 2007 Grand Am Cup ST Championship. Turner Motorsport was the first team to win dual GS and ST driver and team championships in the same season. A fourth Grand Am Championship came in 2011 for driver Paul Dalla Lana. Dalla Lana was also honored by BMW with the 2011 BMW Sports Trophy, given to the most successful BMW privateer racer in the world. Turner Motorsport also raced an E46 BMW M3 in the SCCA Club Racing T2 Class, Will Turner finished 3rd in the 2006 SCCA Runoffs at Heartland Park Topeka in Topeka, Kansas. In 2014, Turner Motorsport switched from the Grand-Am Rolex Sports Car Series to its successor, the WeatherTech SportsCar Championship. Turner competes in the GT Daytona class in the Championship with a GTD / GT3 BMW M6, and has thus far taken class wins at the Monterey Grand Prix at WeatherTech Raceway Laguna Seca, as well as the famous Six Hours of Watkins Glen, the first major endurance win for the team, and followed up with wins at Road America and Virginia. The strength of those four wins was enough to propel driver Dane Cameron to the Driver's Championship in 2014, Turner to the Team Championship, but not BMW to the Manufacturer's championship.
