Additionally, it has been the site of all levels of sports cars racing sponsored by NASCAR, SCCA, IMSA, Can-Am and car clubs.
The Sports Car Grand Prix weekend included a wide variety of cars, classes and race distances. The highlight of the weekend was the Rolex Six Hours of the Glen on Sunday. This endurance race includes the purpose built Sports Racing Prototypes (SRP) similar to the cars in the open class at Le Mans. It also included the GTS, GT and AGT for production based cars extensively modified for racing. Although practice and qualifying are run in separate sessions for faster SRP and SRP 11 cars, during the six hour race they all run together.
Adding spice to the weekend was the Ferrari Challenge bringing together the top Ferrari teams in the United States in a closely controlled class. These are basically stock Ferrari cars whose track modification consisted of driver safety items like roll cage, 5-point harness and the removal of all interior items not needed on the track. Brakes are from the GT 40 race car but the engines are completely stock. These are sealed by the factory for use specifically in this series. So confident is the factory in the quality of its stock engine that no modifications are allowed. This is perhaps one of the key reasons why Ferrari is considered the ultimate sports car.
Race day on Saturday was hot and humid with a potential for thundershowers in the afternoon. This was a concern because the first Grand Am race for Sports Touring cars was scheduled to start at 2:15 and the second for Grand Sports at 5:45. The first Grand Am race ran very cleanly with only two yellow flags, the race ending when 74 laps (250 miles) had been completed. The Grand Sports car race began a little ahead of schedule because of the early finish for the Sports Touring cars.
The GS starting grid had the 925 Porsche of Pobst/Gilbert/Brune in third place while the #55 Corvette of Pilve/McAndrew was in 26th place. After a single warm up lap the green flag dropped and the race was on. However a major accident during the second lap involving three cars resulted in a full course yellow. No sooner had the race restarted and run for a few laps when there was another major wreck and again the safety car came out and collected the field. The yellow flag came out three more times for a total of 15 laps. Because of attrition and pit stops, the #25 Porsche was in third and the 95 5 Corvette was in 11th place.
During the first half of the race, the #55 Corvette was piloted by Jimmy McAndrew whose race plan was to have the car in the top fifteen and lapping at about 2:13. McAndrew's race plan was upset when he ran out of fuel at turn 9 due to a miscalculation of consumption. This had him sit for 15 minutes while he waited for a crewman to bring him gas from the pits. Once refuelled, McAndrew went to the pits for additional fuel and a driver change putting Pilve in charge.
Meanwhile the #11 Corvette and #76 Porsche traded the lead a few times. Going into the final lap, the 476 Porsche was ahead with the #11 Corvette next to him. The fans were on their feet cheering the competitors, excited that after three hours, the race would be decided by a sprint to the finish coming out of the last turn. The #76 Porsche held the line and would not yield to the 11 Corvette who went wide at turn 11 into the front straight. The 976 Porsche of Maxwell/Empringham took the checkered flag by two seconds over the 411 Corvette of Goad/Powell.
The 955 Corvette of Pilve/McAndrew finished 28th, 13 laps down with a best lap of 02:12.240 or 92 MPH. Although running out of fuel put them out of contention, Gilbert Racing and James McAndrew were impressed with Rain's skill and professionalism. In spite of the disappointment, James McAndrew thought that "they should do it again."
