Audi and Nissan were recently testing their LMP1's at Sebring along side a few other teams. I still have a hard time wrapping my head around how fast these cars are able to take turns. Some of these shots look like they're sped up (by a lot), and yet I know that they aren't. It's truly amazing what downforce can achieve.

Most of the footage is of Audi's R18 E-Tron. Check out the shots at 1:13, 1:33, and 2:15.
