Dan Whelson, the Target Chip Ganassi Racing driver set a lap of 25.0619 seconds in his Dallara-Honda.
The test was the first of the 2008 season and the first since the end of the 12-year split between open-wheel's sanctioning bodies. No Champ Car teams participated in Wednesday's test, nor are they expected to participate in another six-hour night session on Thursday or in a three-day test next week at Sebring International Raceway.
However, as many as nine teams could take part in additional tests for former Champ Car teams next month at Homestead and Sebring. Dates of those tests have not been announced.
Wheldon was just slightly faster than his teammate, Scott Dixon, who was followed by Penske's Helio Castroneves, Andretti-Green Racing's Tony Kanaan and Penske's Ryan Briscoe.
