Auto racing after 12 years and several failed attempts by different individuals, the two major open wheel racing series in this country finally got back together.

But it was only for a one-day tire test at Homestead, Fla.

Last Tuesday, the PKV team from Champ Car shared the track with the Indy Racing League's Andretti-Green stable for a Bridgestone/Firestone test.

Oriol Servia and AGR teammates Marco Andretti and Danica Patrick ran together on the 2.3-mile, 11-turn road course inside Homestead-Miami Speedway.

No official times were released but witnesses said Servia's Panoz-Cosworth was about three seconds a lap quicker than AGR's Dallara-Honda, mainly because of the long straightaway.

No media was allowed because, supposedly, neither sanctioning body wanted people to read too much into this brief unification.
