1996 IMSA GT Championship

The 2015 IMSA Tudor United SportsCar Championship (TUSC) season was the second season of the International Motor Sports Association's Tudor Championship, and the 45th overall season of the IMSA GT championship tracing its lineage to the 1971 IMSA season. It began January 24 with the 24 Hours of Daytona.

Classes

The class structure remained largely unchanged from 2014.

  • Prototype (P)
  • Prototype Challenge (PC)
  • GT Le Mans (GTLM)
  • GT Daytona (GTD)
  • 2015 will see the introduction of two awards for the top-finishing Pro-Am drivers in Prototype (P) and GT Le Mans (GTLM). The Jim Trueman Award will be given to the top finishing Pro-Am pairing in Prototype, while the Bob Akin Award will be for the top GTLM pairing. The top Pro-Am pairings from these classes at the end of the year will be given automatic entries to the 2016 24 Hours of Le Mans, with the Trueman award winner eligible for the LMP2 class, while the Akin Award winner would be for the LM GTE Am class. To be eligible for these awards, the drivers must at a minimum contest the North American Endurance Cup events.

    Race schedule

    The 2015 schedule was released on August 10, 2014 and features twelve rounds.

    Calendar changes

  • The events at Kansas Speedway and Indianapolis Motor Speedway have been discontinued.
  • A round at Lime Rock Park was added for PC and GTD.
  • The round at Canadian Tire Motorsports Park will see PC replace GTD alongside P and GTLM.
  • The IMSA Continental Tire Sports Car Challenge support series follows the same schedule as above in 2015 except for the street circuits of Long Beach and Detroit Belle Isle for a ten-round season.
  • On October 31, 2014, the calendar was modified removing PC from the Virginia International Raceway round and adding the class to the round at Detroit Belle Isle alongside P and GTD.
  • The Monterey round would feature all four classes in a single event.
  • Prototype Challenge

    All entries use an Oreca FLM09 chassis powered by a Chevrolet LS3 6.2 L V8.

    News

    Points Systems

    Championship points are awarded in each class at the finish of each event. Points are awarded based on finishing positions as shown in the chart below.

    Drivers Points

    Points are awarded in each class at the finish of each event. Drivers must complete a minimum driving time (outlined to teams prior to each event) in order to score points. A driver does not score points if the minimum drive time is not met.

    In addition, for each car credited with a race start, each driver nominated in that car also receives one additional “starting point.”

    Team Points

    Team points are calculated in exactly the same way as driver points, using the point distribution chart and “starting points.” Each car entered is considered its own “team” regardless if it is a single entry or part of a two-car team.

    Manufacturer Points

    There are also a number of manufacturer championships which utilize the same season-long point distribution chart, minus the “starting points” used for the driver and team championships. (The “starting point” is not used in manufacturer championship points.) The manufacturer championships recognized by IMSA are as follows:

    Prototype (P): Chassis Constructor; Engine Manufacturer GT Le Mans (GTLM): Car Manufacturer; Tire Manufacturer GT Daytona (GTD): Car Manufacturer

    Each manufacturer receives finishing points for its highest finishing car in each class. The positions of subsequent finishing cars from the same manufacturer are not taken into consideration, and all other manufacturers move up in the order.

    Example: Manufacturer A finishes 1st and 2nd at an event, and Manufacturer B finishes 3rd. Manufacturer A receives 35 first-place points while Manufacturer B would earn 32 second-place points.

    The points system from the 2014 season is the same as in 2015.

    North American Endurance Cup

    The points system for the North American Endurance Cup is different from the normal points system. Points are awarded on a 5-4-3-2 basis for drivers, teams and manufacturers. The first finishing position at each interval earns five points, four points for second position, three points for third, with two points awarded for fourth and each subsequent finishing position.

    At Daytona (24 hour race), points are awarded at six hours, 12 hours, 18 hours and at the finish. At the Sebring (12 hour race), points are awarded at four hours, eight hours and at the finish. At Watkins Glen (6 hour race), points are awarded at three hours and at the finish. At Road Atlanta (10-hour race), points are awarded at four hours, eight hours and at the finish.

    Like the season-long team championship, North American Endurance Cup team points are awarded for each car and drivers get points in any car that they drive, in which they are entered for points. The manufacturer points go to the highest placed car from that manufacturer (the others from that manufacturer not being counted), just like the season-long manufacturer championship.

    For Example: In any particular segment manufacturer A finishes 1st and 2nd and manufacturer B finishes 3rd. Manufacturer A only receives first-place points for that segment. Manufacturer B receives the second-place points.
