The calendar for the 2015 TUDOR United Sportscar Championship has been revealed with each of the series’ four classes to contest ten races.
The date at Indianapolis Motor Speedway is the major difference between the schedule for the inaugural season of the combined series and next year’s 12 event schedule. Kansas Speedway, which this year hosted a stand-alone race for the Prototype Challenge class is also omitted from the 2015 schedule. However, after being a fixture in the calendars of both the American Le Mans Series and the Grand-Am Rolex Series Lime Rock Park in Connecticut is brought into the schedule, with the Prototype Challenge and GT Daytona classes headed to the 1.5 mile track on July 25.
All four series race together on six occasions, four of which – the Rolex 24 at Daytona, Mobil 1 12 Hours of Sebring, Sahlen’s Six Hours of the Glen and Petit Le Mans – form the Tequila Patron North American Endurance Cup. The other two occasions where the full grid will join up are for the events at Road America and the Circuit of the Americas.
All four classes will also be in action at Laguna Seca. However, as was the case this year, they will be split between two races.
The other changes from this year’s calendar to the 2015 version are minor, the three classes contesting the only event in Canada – once more at Canadian Tire Motorsports Park – moved around with the PC class replacing the GTD ranks.
There was no confirmation of the race lengths for much of the season, aside from the four NAEC events which will maintain their traditional durations.
The season begins with Rolex 24 at Daytona on January 24-25.
