2003 Multimatic Daytona Prototype

2003 Multimatic Daytona Prototype


Ford looks forward to a future in endurance racing with their Focus Daytona Prototype. A collaboration with Multimatic and Ford Racing has resulted in a new Daytona Prototype scheduled to run in the 2003 Grand-Am season. Multimatic is a Canadian-based company that has large ties to Ford Racing, including a rich racing history including Mustangs.

The new partnership make Multimatic responsible for the development of the chassis, while Ford Racing will lend technical support for their modular-based V8 engine.

Ford Focus Daytona Prototypes will be run by an in-house team for the 2003 Grand-Am season, but Ford and Multimatic have made the chassis available for private sale.

Daytona Prototypes

For the 2003 season, the Grand American Road Racing Association has a new class for prototype racecars. Consisting of current Sports Racing Prototypes (SRPII) and new Daytona Prototypes, this class will represent the fastest cars in the 2003 season.

At the center of the Daytona Prototypes will be a normally aspired six or eight cylinder engine. The framework around the engine is limited to a steel or aluminum in a tubular frame or semi-monocoque setup. The engine must be unstressed. A minimum weight restriction is set from 1975 pounds to 2050 pounds based on engine displacement.
