Rinland will take control of the team's operations and lead its car development ahead of what will be its first campaign in the series.
He was present when the team completed its first run at Vallelunga last month.

He was the designer of Brabham BT56 and BT58 – which between them captured three grand prix podiums – as well as the BT59 and BT60.
He also penned designs for Scuderia Italia and Fondmetal, worked for Benetton between 1996 and '99 and was then the chief designer of the Sauber C20 with which Nick Heidfeld scored his first grand prix podium at Interlagos in 2001.
