Team Penske scored 10 wins in the 17 races that comprised the 2017 IndyCar Series, but remarkably there were still 10 different race winners and the Sonoma finale featured several potential winners of the championship - four realistic, six altogether.
We saw a win for Dale Coyne Racing from Sebastien Bourdais, James Hinchcliffe's first victory since his life-threatening shunt at Indy two years ago, the first road-course win for Alexander Rossi, Takuma Sato scoring the first Indy 500 victory for a Japanese driver and the first win in three years for Helio Castroneves.
This was also the year when criticism of race control seemed to almost disappear, when Curtis Francois proved at Gateway Motorsports Park that IndyCar's oval races can be successful, and when two teams (Juncos Racing and Harding Racing) and several aspiring full-time IndyCar drivers (Zach Veach, Jack Harvey, Esteban Gutierrez, Ed Jones and Zachary Claman DeMelo) made their series debuts, although Jones was the only full-season rookie in 2017.
