After the merger between Grand-Am and the American Le Mans Series was announced last year, a contest was held to name the new combined series, and that new name is now officially the United SportCar Racing series. This new branding will take place at the start of the 2014 season beginning with the Rolex 24 at Daytona.
Fans of the American Le Mans Series are probably losing the most in this new series. Not only is the ALMS name (along with the connection to the 24 Hours of Le Mans) going away, but the more exciting P1 prototype class is also being dropped. In the new United SportCar Racing series, the new Prototype class will consist of Daytona Prototypes, ALMS P2 cars and the DeltaWing (including a new closed-cockpit version). The ALMS GT class will be renamed GT Le Mans (GTLM), while GT Daytona (GTD) will combine the current Grand-Am GT class and the ALMS' GTC cars. The Prototype Challenge (PC) and GX classes will both carry over unchanged from Grand-Am and ALMS, respectively.
