NASCAR has unveiled the rules package and format for this year’s All-Star Race, including two features that could be implemented in the Gen-7 car that is scheduled to be rolled out in 2021.
The first technical element is a single-piece carbon fiber splitter that the series says will improve height sensitivity, as well as offering a more stable aero platform that should translate into better performance in traffic.
Cars will also be fitted with a radiator duct that exits through the hood; a move aimed at improving aerodynamic parity and reducing engine temperatures. Currently, the duct exists into the engine compartment.
The All-Star Race will continue to be four segments split into 30-20-20-15 laps. In the past, the final segment had been 10 laps in length.
Both green flag laps and those under caution will count during the first three segments. Only green flag laps count in the final segment. In the final segment, there will be an unlimited number of attempts at a green-white-checkered finish.
The Monster Energy Open will be comprised of three segments of 20-20-10 laps. Three drivers will transfer into the All-Star Race by winning one of the segments. A fourth driver will transfer in through the fan vote.
Eligibility for the non-points event is earned through having won races in 2018 and 2019, or being a past All-Star Race winner or Energy NASCAR Cup Series champion.
“Throughout its history, the Monster Energy NASCAR All-Star Race has provided a platform to try new and innovative ideas, some of which we have incorporated on a full-time basis,” said Steve O’Donnell, NASCAR executive vice president and chief racing development officer.
“Last year’s All-Star rules package resulted in one of the most exciting all-star races in history. With a similar package, and added elements that we could see in the next generation race car, we expect another must-watch event.”
