Wolf ready, One Motorsport ready, NP01 Auditioning

NAPA VALLEY, Calif. (Nov. 24, 2015) - The 2015 NASA 25 Hours of Thunderhill presented by Hawk Performance is drawing some fast entries in all six classes. The 13th running of the now 25 hour classic will take the green flag December 5.
In the ES class, Wolf Cars and One Motorsports are sure to be at the front of the field throughout the weekend. 

Wolf Cars North America is coming back with their GB08MJ. Driving the car will be team owner, Miles Jackson, IndyCar Champion Al Unser Jr., Pro Drive Racing School owner Todd Harris and Factory Honda Driver Ryan Eversley. The team has made extensive changes to the Wolf and are ready for the 25.

"The car we are racing this year is the same Wolf GB08MJ chassis that we ran last year, but with Honda power," Brian Roberts, director of operations, Wolf Cars N.A. said. "The Wolf GB08MJ is a single seat sports racer built in Italy, with a full tunnel floor for aerodynamic down force. The engine is a Honda Racing, HPD Formula Atlantic built K20, 2-liter naturally aspirated four-cylinder."

The Wolf GB08MJ has been very competitive the last two years at Thunderhill. "We evaluated the issues from the last two years and put a different overall formula together," Roberts continued. "More like the story of the tortoise and the hare, we just replaced the tortoise with a Wolf. We are happy now to be working with Honda Racing. We have a reliable Honda power plant. The K20 has been used in many of the CN cars from Europe and has powered those cars with great reliability. We are focused on reliability and fuel consumption. We have a lot of planning, preparation and testing of all the systems and components for many types of conditions to be ready for December. Talented, smart drivers and crew keeps everyone on task. You can't win if you don't finish. The biggest obstacle for most teams at the 25, including ourselves, is getting to the finish and keeping the car out of any on-track incidents. You can't work on going faster if you are fixing damage on the car."

Another formidable contender every year is One Motorsports with their ultra-nimble Radical.

"We are running one car this year in the 25 hours with drivers John Falb, Todd Slusher, Sean Rayhall and myself," said Jeff Shafer, team owner. "We have prepared this year by running the car more in testing than we ever have before. As in past years, we are planning for the best but preparing for the worst. Our biggest obstacle will be the unknown, you never seem to know until it's happening. It could be the wet or the cold or our car or other cars. We are just trying to be prepared for any situation."

There are two of the all new NASA/Elan developed NP01 race cars entered for the 25. The team at NASA/Elán NP01 Prototype Team No. 01 is taking a unique approach to developing their driver line-up for the twice around the clock plus one hour event next month.

"We will be holding an open test on Wednesday, November 25 at The Thermal Club to test drivers for the race," Drake Kemper, team manager said. "We are going to be basing the test on four main aspects, consistency, smart decision making, overall speed, and attitude. We are documenting the complete event, from building the car to the test and through the race weekend."

Jerry Kunzman, NASA executive director, is pleased with the quality and quantity of entries.

"I think this grid will be the strongest we have seen in the 13 years of running the the NASA 25 Hours of Thunderhill presented by Hawk Performance," Kunzman said. "We have the defending champions Davidson Racing coming back. The Flying Lizard team members with Toyo Tires support this year have a lot of experience running the 25 and there are great cars and teams in in each of the six classes."

The NASA 25 Hours of Thunderhill presented by Hawk Performance will see a field of 63 cars racing in six classes (ES, ESR, E0, E1, E2, E3) going twice around the clock plus an hour over the 2.86-mile, 15-turn track located 90-minutes north of Sacramento.
