2018 NASCAR rules package includes specific design for Daytona, Talladega
NASCAR hopes its 2018 rules package will refine elements of the lower downforce package to produce better racing.
When the 2018 Monster Energy NASCAR Cup Series begins at Daytona in February, its cars will look a bit different than when drivers are at other venues.Â
NASCAR announced itsÂ 2018 rules package Tuesday and newÂ for the superspeedways of Daytona and Talladega will be the elimination of the current ride-height rule. The move will provide safety, competition benefits andÂ eliminate costs for teams.Â
"In doing so we make a significant advancement in liftoff speed," NASCAR vice president of innovation and racing development Gene Stefanyshyn told NASCAR.com. "Somewhere in the order of 30 mph; very, very significant.
"As we do that â€” weâ€™ve had superspeedway specific shock absorbers and springs in the rear of the car. We can now do away with those and just use what weâ€™ve got for the other tracks. It kind of brings all the packages together."
In addition to getting rid of theÂ ride-height rule, all cars regardless of the trackÂ will feature a common flat splitter and radiator/oil cooler for 2018.
"As we do that, some of the downforce will be removed from the car, so we will see a rearward shift in the balance of the car," StefanyshynÂ said. "We estimate somewhere between two to two-and-a-half percentage points backward (approximately 100-120 pounds of downforce).
"So there will be an aerodynamic change. For that reason, weâ€™ve decided to kind of leave things as they are because that will be something that teams will need to deal with. Thatâ€™s basically the big thing on the non-superspeedway tracks as far as the aero package is concerned."
The less downforce, the less grip and drag a car has, thus placing maneuvering more in the hands of drivers than the engineers in the shop. It's a welcomeÂ change for drivers who want to be in charge more than ever and slide around the racetrack for an exciting show for the fans.Â
