DAYTONA BEACH, Fla. – official release — HHP/Harold Hinson photo — Following more than a year of extensive collaboration with stakeholders throughout the industry, and with a keen eye towards the future, NASCAR has finalized and delivered to teams the 2015 racing package for all three national series.
“This race package represents a lot of hard work by NASCAR, the race teams, the drivers, our manufacturer partners and Goodyear,” said Gene Stefanyshyn, NASCAR senior vice president of innovation and racing development. “We’ve remained committed to constantly looking at our racing, and the work that has been done has been aimed at getting a rules package delivered to the race teams as early as possible.”
Highlighted in the NASCAR Sprint Cup Series changes for 2015 are nearly 60 enhancements, including adjustments to the power train, aerodynamics and chassis that are designed to work in concert to deliver drivers more flexibility and teams more adjustability. Fans are expected to benefit from closer racing and more opportunities for drivers to pass on the track.
“We have had fantastic racing so far in 2014,” Stefanyshyn said. “We remain committed to constantly looking to improve it. Our fans deserve it and our industry is pushing for it. That will not stop with the 2015 package; the development will continue over many years to come.”
NASCAR will institute a shorter rear spoiler in its 2015 NASCAR Sprint Cup Series package, which also includes a reduction of engine power, lower rear differential gear ratios and an optional driver adjustable track bar.
Based on the success of group qualifying formats, which were introduced in 2014 for all national series, NASCAR also announced that group qualifying will be utilized for the first time for the Daytona 500. The top two starting positions will be determined through the group qualifying format on Sunday, Feb. 15.
The results from Daytona 500 qualifying will also set the field for the Budweiser Duel At Daytona 150-mile qualifying races on Thursday, Feb. 19. The results from the Budweiser Duel will finalize the starting lineup for the Daytona 500.
Additional changes for the 2015 rules include the elimination of team-facilitated private testing, with race teams being instead invited to participate in NASCAR / Goodyear tests throughout the season. NASCAR also will work alongside Goodyear to introduce rain tires should conditions warrant during road course events in the NASCAR Sprint Cup Series in 2015.
“We’re very pleased with the rules package and what it will do for our racing,” said Steve O’Donnell, NASCAR executive vice president and chief racing development officer. “We’re confident it will continue to generate great racing, along with continuous safety improvements.
“The work alongside our industry has been unprecedented. We’ve had great dialogue with our drivers and teams, our manufacturers and Goodyear, allowing us to build greater efficiencies into the 2015 rules package. We’ve met our goal of delivering rules to teams with time to prepare for next season and we’re seeing the benefits of an updated process for developing our rules paying dividends. It will only continue to improve.”
