For 2016 season bodywork updates were issued by both manufacturers to their aerokits. Compared to the Chevrolet aero kit, the Honda kit saw numerous changes, with the front wing being altered from a stacked triple element, to a simpler dual element section, with a new endplate section introduced. In addition, new sidepods were introduced on the road course kit, while a new tyre ramp was introduced with it, and vents were added to the rear wing endplates. In response to the flipping incidents of Chevrolet powered cars at the 2015 Indianapolis 500, domed skids were reintroduced to the series. Zylon bodywork tethers were also added to the cars, to prevent loose bodywork from leaving a car, and striking another competitor, following the death of Justin Wilson, who was struck by loose bodywork.
Simon Pagenaud driving for Team Penske along with such outstanding pilots as Will Power, Juan Pablo Montoya and Helio Castroneves, became the 2016 IndyCar champion. The Frenchman got off to the best start of his IndyCar career with five consecutive podiums, including three wins in a row. As the season progressed, Pagenaud and his teammate Will Power became the primary contenders for the championship. With a strong run at the end of the season, Pagenaud took his first IndyCar Series championship victory, giving Team Penske another championship victory in its 50th year of racing. He finished the season with five race victories and a total of eight podiums.
