On a warmer, sunny day in April, Jeff Gordon and Trevor Bayne walked off the track and said they were impressed with the way the cars handled in those conditions, too, and both noted that even the tire wear was better than usual. That's become a recurring question since the 2008 race turned into a series of short sprints when tire problems brought out so many cautions.
Goodyear, the series' tire manufacturer, has since softened the tire compound, which produced far better results. That part hasn't changed.
"They've figured it out," said Montoya, who won the 2000 Indianapolis 500. "The grip level is really good today."
Will that be the case in hotter conditions? The Brickyard 400 has traditionally been one of the hottest races in the series.
One possible solution to the heat is adding lights at the speedway, either permanent or temporary. Speedway officials believe running in the cooler nighttime temperatures could make the race better and perhaps boost attendance, which has been dwindling since the 2008 tire fiasco.
Most Cup drivers who have come through Indy, including McMurray, seem to embrace the thought of running Indy's first night race.
"I think if they do that, it would be for the fans. I'm not sure from a driver's perspective that it would be that much different," McMurray said. "But if they do that, I think it would be great."
