The deal includes Official Beer status and signage rights during all of the track's eight annual events. These include Speedweeks, the Daytona 500 and Pepsi 400.
The track's infield concession area will also be renamed "The Budweiser Bistro".
Budweiser, the official beer of NASCAR and driver Dale Earnhardt Jr., will enjoy significant track signage, a major presence on the infield scoring tower in the NEXTEL FANZONE, and use of the Speedway's logo as well as the 2008 50th Anniversary logo.
It will also introduce its 'Green Team' recycling programmes to help keep Daytona International Speedway clean, reports the San Jose Mercury News.
Anheuser-Busch's other beer brand, Busch, has been the title sponsor of the NASCAR Busch Series since the circuit's inception in 1982.
The Daytona 500 is NASCAR's biggest, richest and most prestigious event.
