Andretti Autosport technical director Eric Bretzman returns to Marshall Pruett's Week In IndyCar podcast after his drivers took two podium spots on Saturday at the Dual in Detroit and claimed victory on Sunday with Ryan Hunter-Reay. In addition to a breakdown of the street races, Bretzman explains the engineering challenges ahead on the Texas oval with a series-mandated aero package producing less downforce than teams had available for the Indy 500.

Plenty of great listener questions are answered to close this week's episode, including the answer to what caused Alexander Rossi's tire problems while leading at Detroit 2.
