The LMP1 racer standing on its nose is the No. 8 Toyota TS030 driven by Anthony Davidson, having just recently begun his driving stint and only five hours into the 24 Hours of Le Mans, while the red car next to it is the No. 81 AF Corse Ferrari 458 Italia driven by Piergiuseppe Perrazini. Davidson took the inside line down the Mulsanne Straight, and based on the vantage point in the video, it looks like Davidson had got a decent chunk of the Toyota ahead of the Ferrari when Perrazini turned into him.
The result were hard runs into the tire wall and the end of the race for both drivers. Davidson got out on his own but was sent to the hospital for observation until Monday morning, but thankfully Toyota has released a statement saying Davidson shows "no signs of any injuries." However, reports indicate Davidson has fractured two vertebra, and he soon tweeted from the hospital "Well that was a big one! Lying in a French hospital with a broken back wasn't what I had in mind at this stage in the race..."
The safety car came out while the accident was cleared, but the Toyota team's woes were compounded when the No. 7 TS030 driven by Kazuki Nakajima drove into the Nissan DeltaWing of Satoshi Motoyama on the restart. The contact sent the DeltaWing into the wall (and despite efforts to revive it, out of the race) and the No. 7 Toyota headed back to the pits for repairs and a steep drop down the order. As of this writing, Audi's brace of R18 E-Tron Quattro racers appear to have the inside track on a victory.
