Level 5 Motorsports was testing their LMP 2 car at the Circuit of the America's yesterday. It was a great day for it, until something went wrong and the car crashed into the wall pretty hard.
Details are scarce, but it looks to me like a tire blows in one of the high speed esses. You can see a small puff of smoke from the rear before the spin starts.
It doesn't sound like anyone was hurt, but it sure was a scary looking hit.
