Pourchaire in IndyCar: What does it mean for his work with Sauber?

It will be a busy year for Théo Pourchaire. Sauber's 20-year-old test and reserve driver was confirmed last week as Arrow McLaren's new regular IndyCar driver (although he will have to give up his seat to Callum Ilott for the Indy 500). With 12 race weekends in America ahead, it would have been easy to imagine the Frenchman reducing his workload with the Swiss team. Sauber has updated GPblog about the situation.
