DAYTONA BEACH, Fla. (AP) — The Budweiser Shootout at Daytona will be around at least three more years with a new format that places the emphasis on the four manufacturers in NASCAR's Sprint Cup series.

Anheuser-Busch official Tony Ponturo made the announcement of the contract extension and the format changes Tuesday. He was joined by Daytona International Speedway president Robin Braig and NASCAR spokesman Jim Hunter.

The 31st annual season-opening event at Daytona International Speedway on Feb. 7 will have a field of 24 cars representing the top six teams from Chevrolet, Dodge, Ford and Toyota. It will be based on the final 2008 car owner points.
