Atlanta Motor Speedway officials announced the details of a 2022 reprofiling project Tuesday.
Following Sunday’s NASCAR Cup Series Quaker State 400, the track’s banking will be increased and the racing surface will be narrowed.
The banking in the turns will be increased from 24 degrees to 28 degrees, which will make it the highest-banked intermediate track. The straightaway banking will remain five degrees.
The track’s 55-foot wide turns and straightaways will be narrowed to 40-foot wide turns, a 42-foot wide backstretch and a 52 foot-wide frontstretch.
The track partnered with iRacing and engineers to conduct a ten-month project involving confidential research, development, testing and simulation.
iRacing provided a virtual rendering of each concept floated and data was gathered on how the NextGen car will perform on the reconfigured track.
According to track officials, speeds averaged 200 MPH with the unrestricted NextGen car but averaged around 180 MPH with the restricted NextGen car.
Track officials also stated that there was “not much if at all, any tire wear” on the new configuration, which is in contrast to the current surface’s tire wear that causes lap times to fall off by a few seconds throughout a green flag run.
The track hopes the minimal tire wear will create competitive, pack-like racing.
A test will take place following the completion of the reprofiling project.
The July 10 NASCAR Xfinity Series Credit Karma Money 250 (3 p.m. ET; TV: NBCSN, Radio: PRN) and the July 11 Quaker State 400 presented by Walmart (3:30 p.m. ET; TV: NBCSN, Radio: PRN) will take place at Atlanta Motor Speedway as the last two races on the current racing surface.
