From an Opening Day featuring restyled race cars, the second Angie's List Grand Prix of Indianapolis, a practice session with after-hours running and the 99th Running of the Indianapolis 500 on May 24, the 2015 Month of May at the Indianapolis Motor Speedway will be full of action.

The stars of the Verizon IndyCar Series will take to the 2.5-mile oval for the first time on May 3 for a test session featuring the debut of oval aerodynamic bodywork kits supplied by Chevrolet and Honda.

IMS will then take three days to transition from the oval configuration to the 2.434-mile, 14-turn road course for the Angie's List Grand Prix of Indianapolis. The road course incorporates portions of Turns 1 and 2 and the front straightaway of the oval with the remainder of the circuit within the infield, allowing for great spectator viewing beginning with a free-admission practice day May 7 and qualifications May 8. Simon Pagenaud will look to successfully defend his title on May 9.

"Winning the inaugural Grand Prix of Indianapolis in 2014 was definitely one of the highlights of my career. It's a beautiful circuit and it represents a great way to kick off the on-track activities for the Month of May," said Pagenaud, driver of the No. 22 Team Penske car. "The Verizon IndyCar Series is the most fan-friendly series in the world. To open up the practice on May 7 and the garage on May 8 -- for free -- is an amazing treat for our fans. I hope many of them come out to see our new 2015 body kits and the high-speed racing that is sure to be thrilling."

On May 11, the oval will be host to eight consecutive days of on-track activity with a unique late afternoon/evening practice session from 4-7 p.m. in preparation for the Indianapolis 500. Practice sessions will be held from May 11-15, culminating with Fast Friday (May 15), followed by qualification weekend on May 16-17, including Old National Armed Forces Pole Day on May 17. The next day will feature the final full day of practice, which is always one of the busiest on the track.

"I am really excited for the Month of May activities. Opening Day will be even more interesting this year with the introduction of aero kits, it will be the first time we get on track with them at IMS," said two-time Indianapolis 500 pole winner Ed Carpenter of CFH Racing. "The qualifying format last year was a lot of fun, and I look forward to trying to be part of the action again, but more importantly I can't wait to get another chance to fulfill my dream of drinking milk."

Fans can enjoy their own experiences on the oval May 20 with the IMS Racing Experience and Fan Track Laps. Fans will be able to take Indy Racing Experience two-seat rides around the oval and drive their own cars on the track from 4-7 p.m., while many of the Verizon IndyCar Series drivers will go into the community visiting schools and participating in other outreach activities.

On-track activity continues with Coors Light Carb Day on May 22. In addition to the final Indianapolis 500 practice session, Carb Day will feature the Indy Lights Freedom 100 (practice and qualifying is May 21), TAG Heuer Pit Stop Challenge and Coors Light Carb Day Concert. The eve of the Indianapolis 500 (May 23) features Legends Day Honoring Al Unser presented by Firestone, the traditional full-field autograph session, public drivers meeting and a concert presented by Firestone.

"Anticipation is already building and we are once again excited about our on track schedule as well as the other activities that will make this a special Month of May," said J. Douglas Boles, Indianapolis Motor Speedway president. "Starting with the debut of the aero kits on the oval, followed by the second running of the Angie's List Grand Prix of Indianapolis, the first week of activity will provide a perfect lead up to Indianapolis 500 practice, qualifying and the 99th Running of the Indianapolis 500. May can't get here fast enough!"
