Four of the 11 road and street course races on the 2018 IndyCar schedule are in the books. Here are the rankings of the 10 full-time teams up to this point.
Team Penske took their third win through five races in the 2018 IndyCar season thus far with Will Power’s win in the IndyCar Grand Prix at the 13-turn, 2.439-mile Indianapolis Motor Speedway road course in Speedway, Indiana.
The win was Team Penske’s second victory overall and their second consecutive victory in four road or street course races so far this season, and they became the first team to win more than one road or street course race in 2018.
Dale Coyne Racing won the season opener on the streets of St. Petersburg, Florida with Sebastien Bourdais, Andretti Autosport won on the streets of Long Beach, California with Alexander Rossi, and Team Penske won at Barber Motorsports Park with Josef Newgarden.

However, as a whole, Team Penske haven’t yet had a great road or street course race for all three of their full-time drivers. This includes the IndyCar Grand Prix, as while Power won, Newgarden and Simon Pagenaud both spun out at different points throughout the race.
