There's a lot of uncertainty as to what caused the crash. It seems no video is available, and the initial photos were pulled from Instagram. The photos above come to us from Steven Cairns and were taken by his son James Lee, who was on the scene at the time of the accident. They show a number of details that weren't initially apparent.
Based on the original Instagram photos, Auto Evolution speculated that the accident occurred when the Huayra and another car attempted to merge into the same lane. They initially believed that a drunk driver may have hit the Huayra and sparked the entire accident. That hypothesis changed when Lee's photos emerged. It appears that the Pagani's driver lost control of the vehicle and smashed into a street-parked Peugeot 308.
As you can see from the photos, the entire left rear of the Pagani has been mangled. The wheel is missing and seems to have dragged both suspension components and a good chunk of the blue carbon fiber body with it. What remains is a disaster. The smashed and mangled exhaust hangs loosely from the engine while loose wires lay on the ground like black spaghetti. The suspension that remains is bent while the vehicle seems to be resting on part of the engine.
The body panels that still remain have shifted, as many of the panel gaps are mismatched and uneven. Up front, it appears that the airbag went off as the windshield appears to be smashed on the passenger side. The passenger seat belt appears to be buckled, meaning someone may have been riding shotgun when the accident occurred.
Lee's photos show part of the rear bumper, complete with a Saudi Arabian license plate. The missing wheel still has suspension bits attached. The rest of the Huayra Pearl seems to be relatively fine, all things considered.
It's not clear what will happen to the car now. Pagani only built 100 Huayras, and the Pearl is a one-of-a-kind edition. Hopefully, the car is able to be repaired and get back on the roads, preferably in the hands of a more capable driver.
