Storyline – A peak at new rules package on tap at Open/All-Star week: In addition to the unique format of racing during All-Star week at Charlotte Motor Speedway, NASCAR teams and fans will get a look at some potential rules package changes for the future. The Monster Energy NASCAR Cup cars will feature two significant changes compared to the current speedway package – (1) a single-piece carbon fiber splitter/pan that will provide a more stable aero platform and create more consistent performance in traffic; and (2) a new radiator duct which exits through the hood and not into the engine compartment, which will create improved aerodynamic parity and reduce engine temperatures. The All-Star race is broken into four segments – 30 laps, 20 laps, 20 laps and 15 laps. That format, with teams having four race sets of tires at their disposal, will lead to varying strategies throughout the night.
“The All-Star race is always a big night for the sport of NASCAR,” said Greg Stucker, Goodyear’s director of racing. “Not only do the short segments lead to a sense of urgency with teams deciding on different pit strategies, but this year we have the added excitement of testing out some new elements that we may very well see incorporated into the Cup cars in the future. The All-Star weekend is a great chance to try some of these things and get a real world look at how they perform on the track in race conditions. We will run the same tire set-up for both weeks of Charlotte, so the next two weeks will provide good data points for what is working. All that with the backdrop of $1 million to the race winner will make for an exciting night of racing.”
