With the merger of Grand-Am and ALMS, from 2014 onward there is but one prototype and GT racing banner, the Tudor United SportsCar Championship (USCC). September 27-28 is the Grand-Am Championship Weekend presented by BMW at Lime Rock Park, the 141st – and last – Grand-Am Daytona Prototype race in the world.The first Grand-Am Daytona Prototype race was the 2003 Rolex 24 at Daytona; fourth overall and first in DP was a Ford Multimatic driven by Scott Maxwell, David Epringham and David Brabham (a GT-class TRG Porsche GT3 RS won).(Lime Rock has run a Grand-Am DP race in each of the past three years; in previous years, Lime Rock has also held stand-alone Grand-Am Rolex GT and Continental Tire Sports Car Challenge events. Lime Rock Park has been a bastion of U.S. sports car racing since its opening in April, 1957.)This weekend, there are eight Rolex DP drivers within 15 points of each other for the 2013 title: Wayne Taylor Racing’s Jordan Taylor and Max Angelelli (304 points); Ganassi Racing’s Scott Pruett and Memo Rojas at 296; GAINSCO’s Jon Fogarty and Alex Gurney, 293; and Action Express Racing’s Christian Fittipaldi, 291, and Joao Barbosa, 289.In Rolex GT, five drivers are within 11 points: Andy Lally and John Potter have 313 points, Alessandro Balzan is at 309, and Robin Liddell and John Edwards have 302.
