Confirmation of the split after what will be four seasons has been provided by Ganassi managing director Mike Hull, who told Autosport that “we are ending this chapter” of a long relationship with Cadillac parent company General Motors that has straddled IndyCars, NASCAR and Extreme E as well as sportscars.
He said that it was coming to an end in a “very positive way”, adding that he doubted that it would be “the last time we work with GM on a racing project”.
