TC Daily Pit Stop: NASCAR's 'Lift Splitter' Test 'Not A Home Run' After Monday; Entry Lists for Michigan
TC Daily Pit Stop: Tuesday, August 1st, 2023
The latest attempt by NASCAR to improve upon the short track aero package in the NASCAR Cup Series will need some further tinkering after the first day of a two-day test session at Richmond Raceway provided subpar results.
On Monday, the six drivers and teams participating in the test were the first to hit the track with the new aero package featuring an angled “lift splitter” – designed to reduce the negative impact of turbulent air for the trailing cars according to computer modeling and wind tunnel testing.
However, the results of the test session – at least from the first day, where the aero package was tested without different tire combinations – weren’t as positive as the sanctioning body had hoped.
William Byron, Noah Gragson, and Christopher Bell all provided their thoughts on Monday’s test, while NASCAR Vice President of Vehicle Performance Dr. Eric Jacuzzi provided thoughts on behalf of the sanctioning body.
