Las Vegas Motor Speedway will host a major two-day organizational test for Cup and Xfinity Series teams starting Thursday.
The test is significant because it will be the largest collection of teams to test the Cup Series’ 2019 rules package at the same time.
“We don’t know what we don’t know,” said Brad Keselowski, who will take part in the test, on how the new package will be on track. “You’ll figure it out.”
There will be 21 drivers involved, including 16 Cup drivers and two full-time Xfinity drivers, Noah Gragson and Chase Briscoe. Ross Chastain, David Ragan and Drew Herring each will drive manufacture wheel force cars. Xfinity drivers Zane Smith and Riley Herbst will also be present.
The test, which is open to the public, will be from 11 a.m.- 10 p.m. ET Thursday and from 11 a.m.- 4 p.m. ET Friday.
On Thursday, the first of three drafting practice sessions will begin at 2 p.m ET. The other two drafting practice sessions are scheduled for 6 and 8 p.m. ET.
Friday will feature two drafting practice sessions at Noon and 2 p.m. ET.
