Three months after Levi Jones left his post as Penske Entertainment’s Indy NXT director, the company has found his replacement by reaching back to one of its CART IndyCar Series crew chiefs.

Richard Buck, who helmed Penske Racing cars for Rick Mears, Emerson Fittipaldi, Danny Sullivan, and others before moving onto other teams and went on to become the managing director of NASCAR’s Cup Series in the 2010s, will lead IndyCar’s lone development series.
