New rules have been released for the 2021 NASCAR Cup series and they will mainly target the High downforce and low downforce strategies for another time.
Nashville and Darlington will be utilizing the low downforce 750hp package which is 250hp extra from the previous 500hp package, which all rounds longer than 1.1 miles ran for the 2020 NASCARCup season.
Gen-6 will be bidding farewell to NASCAR at the end of 2021 season before the Next Gen car hits the track for the 2022 season.
In addition to the high downforce and low downforce packages, the following changes on low downforce were also made:
1.Smaller rear spoiler, shrinking from an 8-inch height to 2.75 inches.
2. The front splitter overhang measures a quarter-inch (down from 2 inches), with approximately 2-inch wings (reduced from 10.5 inches).
3.Alterations to the radiator pan, removing its vertical fencing in an effort to reduce front-end downforce. The dimensions of the pan remain the same.
“We constantly review the race packages to try to put on the best possible racing for our fans,” said NASCAR’s senior vice president of innovation and racing development, John Probst.
“When we brought in the short track/road course package this season, Darlington was not part of it due to its unique size. We’ve been evaluating data from both race packages, as well as feedback from drivers, teams and OEMs and feel that the 750 hp/low downforce package best fits the track.”
