12 Hours of Sebring Hour 1: Wet start

| Derani leads in the #31 (photo taken Friday) |
The 12 Hours of Sebring started behind the pace car because a heavy rain showers that hit the Sebring, Florida airport circuit all morning.
The first 40 minutes ran under the yellow behind the pace car but when the green flag dropped on the still wet track the the #5 Cadillac and #31 Cadillac blew off the pole winning #6 Penske Acura like it was standing still. The traction control of the Cadillac is said to be a better system than the Acuras.
How slow are the Acuras? In the wet they were losing 15 seconds per lap to the Cadillacs and were lapped in the first 20 minutes of green flag running. The LMP2 and GTLM cars blew them off as well. If it stays wet much longer their race will essentially be over.
In GTLM the #67 Ganassi Ford GT is struggling to hold off the #25 Rahal BMW.
