The 52-year-old chief engineer for Marco Andretti has been around the INDYCAR paddock for quite some time, coming to the series in 1995 after working with a Trans-Am team.
From there, it was a six-year stint with KV Racing before moving over to Andretti Autosport, where he has worked with Andretti and Carlos Munoz.
Andretti had two more fourth place finishes at Toronto and Sonoma to give him 13 top-10 finishes in 19 NTT INDYCAR SERIES starts.
Mothershead is hoping to devise a way to get Andretti better results.
Garrett Mothershead: “The biggest thing is consistency and getting off to a smooth start.”
