Guess who?

1985 was the year you could find many Porsche 962s. They had been introduced the previous year and they began to dominate IMSA as soon as they were sorted out. The entry list was quite attractive, and every class had its share of good cars. Seven Porsche 962s were entered, and Al Holbert's car still appeared as the one to beat. Holbert Racing had entered its backup car for Al Unser Jr. Dyson Racing had one car for Rob Dyson himself, Drake Olson and Price Cobb. This car could be the real contender for the overall after two wins in Lime Rock and Road America. Bob Akin had entered his Coca Cola backed 962 with Hans Stuck as a co-driver. With such a driver, you could expect the best race as possible. BF Goodrich had two cars, with Jochen Mass and Jim Busby on the first one, and Pete Halsmer and John Morton on the second. A very good team indeed, but plagued with tyre problems throughout the season. Bayside Disposal had a car for Bruce Leven, who was partnered by French star Bob Wollek. The opposition was materialized by two Jaguar XJR5s for Hurley Haywood and Brian Redman on the #04, and Bob Tullius and Chip Robinson on the #44. They had won the Road Atlanta race at the beginning of the season and were desperately searching for another success. Ford had entered a Probe prototype for drivers Klaus Ludwig and Doc Bundy. The car was fast in practice but had trouble finishing the races. The car needed to improve its reliability. Conte Racing had entered a single car for Bill Adam. The car had proved fast too but was plagued too by reliability problems.

The new Corvette GTP was here too and David Hobbs and Vern Schuppan were the drivers. It was still under developed and was beginning its racing career. A second car was entered by Lee Racing, quite similar visually, it was an independant effort with semi-pro drivers. Lew Price and Carson Baird were at the wheel. John Kalagian had a Porsche powered March 85G for himself and the Leon Bros had two cars for Skeeter McKitterick and Sarel van der Merwe. That looked like an attractive GTP field! The new Camel Lights class had been intorduced at the beginning of the season and many cars were to be seen at the Glen. A Mazda GTP was here with David Loring driving could be a nice contender for the two Mazda Argo JM19s. Jim Downing and John Maffucci were the favorites while Kelly Marsh with brother Don Marsh and Ron Pawley would be there too. One Alba and two Tigas were there and had some hopes. The GTO class was the home of the Ford Mustangs entered by Jack Roush. Three cars were entered for John Jones on the #65, Lyn St James on the #07 and Fernando Robles and Chris Marte on the #62. Another independant car was here driven by Jim Robbins and Dave Watson. The opposition was to be the Brooks Racing Ford Thunderbird driven by talented Darin Brassfield and the beautiful Peerless Racing Chevrolet Camaro which was driven by Craig Carter and Gene Felton. Electrodyne Performance entered its efficient Porsche 934 that could do well on such a track. Chet Vincentz had won the previous year race on this track. His co-driver was Dutchman Kees Nierop. A bunch of Chevrolet Camaros, a single Chevrolet Monza and some Corvettes were the usual GTO fixture along with three Pontiac Firebirds. Tommy Riggins was here but not on the usual Dingman Bros car. He was partnered by Andy Peterey on the Road Circuit Technology car. The GTU class had a lot to promise. The Mazda RX7s were still the favorites, but Pontiac had the Fiero now, and the cars proved to be real contenders for the win. So Roger Mandeville, Al Bacon and Jack Baldwin had to be very cautious about their opponents. Terry Visger and Bob Earl were the Huffaker Racing Pontiac Fiero drivers. Bob Leitzinger had a brand new Nissan 300ZX that was still a new car, but it would provide soon some stiff opposition. A pair of Porsche 911s and 914s did complete the GTU field.

Fifty two cars would take the green for their second visit of the year at the Watkins Glen 500km race. Al Holbert was not on the pole but not too far from fast Hans Stuck , who was driving the Bob Akin Porsche 962. Plenty of close action was to be awaited, and it was Al Holbert who jumped in the lead at the start of the race. A March driven by Sarel van der Merwe was to avoid Bill Adam's March Buick and hit another March driven by John Kalagian, who landed in the pits in a quite odd fashion. Sarel van der Merwe would not go much farther and stopped to replace his torn bodywork. Up in front, Hans Stuck did not see it the Al Holbert's way, and he was back in the lead, trying to pull ahead of his closest opponent. A lot of close action was to be seen on the track with Darin Brassfield, Chris Cord and Kelly Marsh fighting hard. Unfortunately, this battle was not to last for long, as Chris Cord hit the Armco barrier at turn eleven. This resulting in a safety car period, with many cars coming to the pits for refueling. When the safety car went out, Hans Stuck was always in the lead, but he would soon experience a broken halfshaft, and he retired later.

Al Holbert was now in the lead, and for good. Behind him, the Dyson Racing Porsche 962, driven by talented Drake Olson, seemed willing to get in contention for the lead, but he would have his windshield covered with oil from another car, and Drake Olson would have to literally crawl back to the pits, and lose a great deal of time. That left the BF Goodrich Porsche 962 driven by Jochen Mass and Jim Busby in second place, but they could not run as fast as Al Holbert. In third place was the Group 44 Jaguar XJR5 driven by Brian Redman and Hurley Haywood, just ahead of the fast qualifying Ford Probe of Klaus Ludwig and Doc Bundy, which running not so fast. The GTO category was dominated by the two Fords : the Mustang driven by John Jones and the Thunderbird driven by Darin Brassfield and Scott Pruett. Leading the way, the Mustang would break after thirty five laps, and it would be Lyn St James who would take the lead and finally won the race. She would hold off a challenge by Craig Carter's Chevrolet Camaro. The GTU category was dominated by Bob Earl driving a Pontiac Fiero. But he broke too and Jack Baldwin was suddenly leading his class. The same could be told about Pierre Honegger, leading the Camel Lights class who retired at mid race, leading the Marsh brothers in the lead with their Argo JM19 Mazda. They would hold it until the last refueling pit stop and lose their position to the similar car driven by Jim Downing and John Maffucci. The end of the race was to be some kind of routine for the Al Holbert and Derek Bell duo. Al Unser Jr, who was driving the Holbert Racing Porsche 962 backup car, was doing a great job in a car that was probably less efficient than Al Holbert's car. At the end of the race however, he did receive a piece of debris that shot from his bulkhead in the final lap. Slightly injured, he would remember that race. Al Holbert had won again, and clinched the IMSA Championship for the fourth time in his career. Lyn St James had won the GTO class. In doing so, she became the first female driver to win a GTO race in IMSA history. Jack Baldwin won the GTU class over Terry Visger who finished on the same lap. According to many, such a promising race quickly turned into a bore as Al Holbert dominated the event, but nobody could blame him, right?
