I thought this was intereting:

From the article:
“At first I was skeptical about how the IndyCar would perform on a road course,” quipped Carpentier about his Sebring day, “but as soon as I got a feel for the car it proved me wrong.”
That's good news for next year and seems to follow what others have said. Interesting that he's not the only one to be suspecious of IRL cars on a road course, only to find the opposite.
"When faced with an IndyCar’s specialty, such as Homestead’s oval, the French-Canadian deemed the experience 'more exciting than [in] a Champ Car.'"
I found that particularly interesting considering others past comments of IRL cars, particularly the much publisized characterization that they were dung wagons. (I am not mentioning that to be antagonistic, let's be civil)
