WILLOWS, Calif. (Dec. 5, 2015) - Officially 58 cars took the green flag for the start of the 13th running of the 2015 NASA 25 Hours of Thunderhill presented by Hawk Performance today at 11 a.m.

The No. 17 Davidson Racing Norma, last year's overall winner, has led the race from the start. They nearly gave up the lead four hours in when the NASA officials called them to pit lane to serve a 10-minute penalty for passing under yellow. This allowed the second place runner, ES Class No. 45 Audi of Flying Lizards, to make up four laps and get on the same lap as the 17. At six-hours it is the 17 out front with rain expected by 2 a.m.

"I had a good start to the race," said Brian Frisselle. "It opened up for me and I was able to take the lead. I then settled into a pace and was able run pretty comfortably upfront. We had to take a 10-minute penalty when Kyle Marcelli passed under yellow, which erased the few laps lead we had, but we are back to running upfront. Everything is going great with 17 car."

In ES the No. 45 Flying Lizard Audi is one lap behind the leading Davidson Norma.

"I did a double stint, I was second in the car," said Tomonobu Fuji. "There were three caution periods during my stint, so it was a little crazy. The Toyo Tire is really good here. My stint was very consistent thanks to a good car, good tire and good crew. There is always traffic out there, so you have to really pay attention. We ran in the rain on Thursday and the car was good on the Toyo rain tire so we are ready."

In E0 the No. 61 RoadShagger Racing BMW leads the class.

"It is going very well we are leading our class," Gavin Ernstone said. "We had some issues yesterday. We were a little disappointed qualifying fourth, but we have progressively moved into the lead. We have had good driving and good pit work and everything is going according to plan. The rain will add some excitement and bring out a different level of driving talent."

In the E1 Class, the No. 14 Technik HQ Autosport/Active PDF BMW is at the front.

"The start was really, really good," said Peter Hopelain. "We picked up four positions by Turn 1 on the first lap. We then settled into a pace and were running good. On lap 10 I had a prototype come up on me and I had to go off the track and that put us back about 30-seconds. We changed up our strategy a little. We fell back to fifth, went back into the lead and we are strategically placing our car forward. I want to thank our sponsors Active PDF and Ocean Side Motorsports. They have done a stellar job giving us a great driving car. Without those two companies we would not be here."

The E2 Class is being led by the No. 34 Mazda RX8 of RDR Racing.

"So far so good, we really haven't had much drama," Robert Davis, team owner said. "We are leading with the RX8 and the new Mazda Miata MX-5 Cup cars are a little over classed. We are fighting amongst ourselves with those. This race is a whole season of the MX-5 Cup series. We have about 900 miles on the cars so far with no issues. The rain keeps getting pushed back, so we will see how it goes."

In E3 it is the No. 13 SP Racing Miata in the lead.

"The first stint was challenging with all of the traffic out there," Hernan Palermo said. "I had a little issue and had to come in and do a fast front end alignment. I hope to see some rain that can only help us."

In the new NP01 car, CLP Motorsports continues to lead.

"The start of the race was good," Tyler McQuarie said. "We didn't get involved in anyone's mistakes. We have struggled with axles a little, but I think we have it figured it out. The car is running pretty good right now. We did a few laps in the rain during the test day. We made some set-up changes anticipating the rain and I think they will put me in to slide it around when it gets wet."
