Australian Will Power proved fastest of the Champ Car converts on the first day of a special IRL oval induction test at Miami's Homestead speedway.
Eight of the nine former Champ Car entries confirmed for the reunified IRL IndyCar Series completed a combined total of 598 laps on Monday, alongside Roth Racing, who failed to make the open test in February.
The Champ Car refugees, joined by Newman Haas/Lanigan drivers Justin Wilson and Graham Rahal, who missed last week's road course test at Sebring, were set a 195mph speed limit to begin with as they dialled-in their Honda-powered Dallaras, with the IRL increasing that limit as the test continued.
Former IRL part-timers Roth Racing set the pace overall with team owner Marty Roth outpacing teammate Jay Howard.
IRL president and CEO Brian Barnhardt commented afterwards that the first part of the test had gone smoothly.
"The teams are working awfully hard," he said. "We're getting close to event time and clearly track time and seat time is the most valuable commodity."
The test continues today with Bruno Junqueira joining for the second day with Dale Coyne Racing.
The season begins at Miami's Homestead venue this weekend.
