Crash video from the American Le Mans Series Petit Le Mans practice

"I really don't know what happened...I was heading up the hill in sixth gear and felt a hit in the right rear. The wheel arches are very high with the wide front tires on the Acura - I didn't see a thing – only felt the contact. I knew it was a big one and I am just really grateful to Acura and all the boys at Patrón Highcroft Racing for building such a strong car. I'm shattered for Duncan, all the guys, Brabs and Dario (Franchitti). We went through this last year and I can't believe it's happened again. I was just thinking to myself how much I like this place when next thing I'm headed upside down with a mouth full of Georgia clay."

-Scott Sharp, driver Patrón Highcroft racing
