Kurt Busch emerged fastest in a rain-delayed final practice session for the 2014 NASCAR Sprint Cup-opening Daytona 500.
Light rain caused the session to be postponed by an hour and came after one of Friday's practice periods was canceled due to precipitation.
Busch and Kasey Kahne took turns at the top of the time sheets once the track was deemed dry enough for running and it was the Stewart-Haas driver who ultimately triumphed. He reached 197.624mph around the 2.5-mile superspeedway with less than 10 minutes of the session completed and his effort remained unbeaten until the end.
Kahne also maintained second on the speed chart until the chequered flag, ahead of Jamie McMurray, Carl Edwards and Martin Truex Jr., who managed to complete 13 laps in his back-up Furniture Row Chevrolet.
The majority of the drivers chose to run in Saturday practice as a final shakedown of their cars and the session passed with no incidents.
Those who chose not to participate included polesitter Austin Dillon and 2004 race winner Dale Earnhardt Jr., both of whom elected to preserve their cars for the main event.
