In a teleconference that took place shortly after NASCAR released its 2014 Sprint Cup rules package, the series’ vice president of innovation and racing development, Gene Stefanyshyn, stressed that it was just step one in a process of improving the racing with the Generation 6 cars.
With the 2014 season set to unofficially kick off early next month with the Preseason Thunder test sessions at Daytona, Stefanyshyn said that NASCAR was limited by timing in regards to how many changes it felt it could pull off with the package. As a result, he said that “it shouldn’t be construed that [the package] is the final solution.”
“The amount of flexibility we had given timing was not as great as we have say working on , we’ve got a whole year ahead of us,” he said. “So this is really the first installment in a journey towards a continual improvement process in regards to our race product.”
Stefanyshyn explained tweaks to the chassis set-up for the 2014 season that eliminates light springs used to bring the car to inspection height and how heavier springs in the front end will keep teams from having to load the entire car on its suspension. He hopes that these changes will provide a more stable car for drivers in the middle of traffic.
He also took reporters through the elimination of the pre and post-race front height rules. Cars will remain on blocks during the inspection process but when those get off the blocks, teams will then change the car to what he called “race attitude.”
“If they want to drop the front end of the car down to half an inch, they’re able to do that,” he said. “If they want to drop it to 1.5 inches, they’re able to do that. So we’re actually letting them put the car in more of a race position.
“Because what happens when the car is sitting there statically at 4.25 inches, as soon as it gets on the track, the downforce on that car drives the front end down towards the track anyway. But then what happens is that front end tends to bounce and load and unload, and this is how you get some of the instability.”
Downforce should be increased with the implementation of a bigger radiator pan and rear spoiler, the latter of which will have its top two inches in clear Lexan for visibility purposes. Speed should also go up thanks to the changes, so the RPMs will be brought down slightly to a planned maximum range of 9,300 to 9,400 – which according to Stefanyshyn should end up as a cut between four and six percent.
Interesting to note is the lack of a tapered spacer on the 2014 rules package, which would have resulted in lower horsepower on the Cup cars. Stefanyshyn said the option is still on the table for 2015, but that the aforementioned timing issues played a role in them deciding not to use it now.
“We’d like to be able to do perhaps three things at once, and we think we can come up with a more robust solution that can serve us better in the longer run,” he said. “So this is something I think we are going to definitely look at for ’15.”
