Will Power and Helio Castroneves still run awfully fast at Barber Motorsports Park going into the season.

The Penske Racing teammates posted the two fastest laps in testing Tuesday at a track where they've combined to win the first three IndyCar races.

Power's fast lap of 1:07.8625 was more than 2.6 seconds faster than the run that secured the pole for Castroneves a year ago at the 2.3-mile track. Castroneves was next up with 1:07.9388, followed by James Hinchcliffe (1:07.9869).

Power, the series runner-up last year, says the faster times were a product of engine work and cooler weather. He called it "just a very fast situation."

There were some changes even with familiar faces at the top. Four drivers are with new teams, and AJ Allmendinger's back in IndyCar.
