The history of IMSA is one to remember, and now it returns with just one sportscar series overseeing the era to come.
ITR Chairman Hans Werner Aufrecht talks about the background of the new agreement with GRAND-AM and IMSA.
Manufacturers from Audi, BMW, Mercedes to Nissan, Honda and Toyota all onboard.
United SportsCar Racing series will include DeltaWing alongside DP, P2.
Last year when GRAND-AM and ALMS developed the initial plan to unite the two top North American sportscar series, they knew that the logo and brand name had to be marketable plus please their fans.
Grand-Am and ALMS will be one series in 2014 under their newly announce series name.
