Last week, rumours started after Michael Andretti announced he was quitting, with immediate effect, as owner of the racing team that bears his own surname. For instance, the American was said to have fallen out with business partner Daniel Towriss, the new owner of Andretti Global. It was also suggested that Cadillac would only join an F1 adventure with Andretti on the condition that Michael would no longer be the owner. In an interview with GPblog, the Andretti family responded for the first time.
