The 500 Miles' Week in Review.

New information from the past week in the IndyCar world.

-Simona De Silvestro started her training again on Wednesday, which was the first the first time since her crash at the Milwaukee Mile on June 18th. De Silvestro has been suffering from post-concussion symptoms the past couple weeks, but is reporting that she is feeling a lot better. She still has to be cleared to race by IndyCar Series medical staff, in order to race at Toronto on July 10th.

-Will Power was cleared to go back into his Penske car on Wednesday. That same day he started testing with teammates Ryan Briscoe, and Helio Castroneves at Mid-Ohio Sports Car Course.Which was just less than 4 days after being diagnosed with a minor concussion from a crash at Iowa.

-The testing on the new 2012 IndyCar Series Dallara chassis will begin August 8th. It will be held at either Mid-Ohio Sports Car Course, or in Sebring, FL. Another test is scheduled at the Indianapolis Motor Speedway sometime the last week of September. The chassis will be tested along with the new Honda V6 turbocharged engine, since it is the only engine that's ready to go as of now. Dan Wheldon, and Bryan Herta Autosport will test the new chassis.
