Will Power topped the speed charts for a second consecutive day of IndyCar testing at Barber Motorsports Park.
The Penske Racing driver turned a lap at 1:07.1329, which was more than 3 seconds faster than last year's pole winning time set by teammate Helio Castroneves.
The fourth and final session Wednesday afternoon saw 14 of the 28 driver-car combinations post their best lap times. James Hinchcliffe was right behind Power at 1:07.3839, followed by Justin Wilson and Scott Dixon.
But Tony Kanaan's time of 1:07.5478 in Wednesday morning's session stood as fourth best overall.
James Jakes tested Wednesday for the first time with new team Rahal Letterman Lanigan Racing. He was ninth quickest in the afternoon and 11th overall.
