Before this last event, Allmendinger has been also part of the Penske team at Barber, Long Beach and Detroit double-header.
Team owner Roger Penske said that Allmendinger would be a valuable addition on the weekend where both the drivers' and manufacturers' titles will be decided.
The former ChampCar ace’s best result in his IndyCar appearances with Penske this year was at Indianapolis, where he led 23 laps on his way to finishing 7th.
