Team Penske race engineer Ben Bretzman, winner of the 2016 IndyCar championship with Simon Pagenaud, joins Marshall Pruett as guest host of the #WeekinIndyCar podcast to discuss the announcement of Carlos Munoz's return to Andretti Autosport for the Indy 500, the possibility of Esteban Gutierrez joining Ed Carpenter Racing, where Conor Daly stands on finding a ride, the upcoming name change for Laguna Seca, and the data sheets from Ayrton Senna's IndyCar test with Team Penske 25 years ago on Dec. 20. 

The two close cover almost two hours of fan Q&A, with a good portion covering Bretzman's world of race engineering. If you're after knowledge on working with race tires, chassis setup, and many of the inside details of how he and others on the timing stand ply their trade, settle in for a hearty-and-fun episode leading into the holidays.
