Reutimann crash among hardest ever

The g-force impact during David Reutimann's crash Sunday at California Speedway is among the hardest ever recorded, NASCAR officials told ESPN.com on Monday.

NASCAR doesn't disclose exact figures.

"We can't say it's the hardest [impact], period, because there are so many variables involved," NASCAR spokesman Ramsey Poston said. "But it is among the hardest impacts we've recorded."

Reutimann was riding along one lap down with 11 laps remaining in the Auto Club 500 when Greg Biffle approached from behind. Biffle tapped Reutimann, sending the No. 00 Toyota head-on into the outside wall. The car lifted off the ground and was completely destroyed. ESPN.com
