The entries for Dario Franchitti, Charlie Kimball, Josef Newgarden and Graham Rahal will incur 10-grid spot penalties for the first race of the Chevrolet Indy Dual in Detroit presented by Quicken Loans on June 1 because of unapproved engine changes at Indianapolis.

IZOD IndyCar Series entrants are allowed to switch out their Chevrolet or Honda 2.2-liter, turbocharged V6 engines once they meet the 2,000-mile threshold or by INDYCAR approval for repair.

Honda engines in Franchitti's No. 10 Target Chip Ganassi Racing and Kimball's No. 83 Novo FlexPen were swapped out before Pole Day qualifications. The Honda engines in the No. 15 Midas/Big O Tires car for Rahal and the No. 21 Century 21 car for Newgarden were changed out to their Indianapolis 500 Race engines for their qualifying attempts on Old National Armed Forces Bump Day on May 19.

Qualifications May 31 for the first race of the IZOD IndyCar Series' inaugural race weekend doubleheader will follow the three-round format for street/road course events, including the Firestone Fast Six to determine the Verizon P1 Award. Get tickets to the events May 31-June 2 HERE.

Full-season entrants may use no more than five fresh-built engines from the first Open Test in mid-March at Barber Motorsports Park until the end of the race season Oct. 19 at Auto Club Speedway. For each fresh engine installed during this time, a grid spot penalty will be issued. Full-season entrants are allotted 10,000 miles of running per calendar year.

The fresh engine fitted for the Indianapolis 500 shall count as one of the five allotted to full-season entrants, which have the option to use up the mileage in that engine for subsequent races or refit the previous engine for the balance of its mileage and then use the Indianapolis 500-fitted engine.
