Dale Earnhardt Jr held off NASCAR Sprint Cup points leader Matt Kenseth to claim pole for Sunday's Chase race at Dover.
Hendrick driver Earnhardt's 22.243-second, 161.849mph lap was the latest in the string of new track records set by the Gen-6 cars this year.
Kenseth, who has won the first two Chase events, was 0.006s shy of beat Earnhardt in his Joe Gibbs Toyota.
Even by NASCAR short-track standards, the field was incredibly close, with the top 10 cars all within 0.089s.
Ryan Newman was third for Stewart-Haas, joined on row two by Carl Edwards in the best of the Fords for Roush Fenway.
Aric Almirola and Brad Keselowski both had spells on provisional pole but ended up sharing row three, followed by Jamie McMurray, Jimmie Johnson, Kurt Busch and Martin Truex Jr.
The race takes place on Sunday afternoon.
