Porsche fanatics should be stoked by the collection of 12 historic race cars and sports cars representing 48 years of production offered at RM Auction’s annual Monterey sale Aug. 17-18 during Pebble Beach Concours week.

The “Rennsport” roster is led by one of Porsche’s greatest sports racing cars, a well-documented 1971 Porsche 917/10 Spyder Can-Am that was originally driven by Jo Siffert. RM estimates its value between $2.9 million and $3.5 million.

“The Porsche 917/10 is unquestionably one of the most desirable Porsches ever built and is certainly on a very short list of the marque’s most legendary racing cars,” said Annette Abaci, Car Specialist, RM Germany. “With its unique history that includes none other than Swiss racing great Jo Siffert and a professional restoration carried out to the most exacting standards, we expect this Porsche to garner strong interest from ‘Rennsport’ aficionados at our upcoming Monterey sale.”

After its debut at Watkins Glen, the 917/10 ran in five more races in that Can-Am season, although Siffert was killed in an unrelated crash. The 917/10 was rebuilt by the Porsche factory for the 1972 European Interserie and raced successfully by Willi Kauhsen, whose family owned the car for more than 25 years after its racing career ended. After a professional restoration to its original Can-Am specs, the car has competed in historic events at such venues as Goodwood and the Oldtimer GP at the Nürburgring.

Another Porsche highlight is the completely restored 1963 Porsche 904/6 Carrera GTS factory works prototype, the second of Porsche’s 904/6 factory team cars of which only five survive. It is not just one of the few developmental prototypes built in 1963 but one of the few 904/6s to retain its original 906 six-cylinder engine. Value is estimated between $1.8 million and $2.2 million.

Porsche racing is further represented at RM’s Monterey by pair of 1980s-era IMSA racing cars: the dominant 1981 Porsche 935 JLP-3 and the championship-winning 1987 Porsche 962 IMSA Camel GT.

The 935 at RM is the most successful of all Porsche 935 race cars. The 1982 IMSA Camel GT Championship winner campaigned by the father-and-son team of John Paul Sr. and Jr., as well as the great Derek Bell, is the only car to have won both the Daytona 24 Hours and the Sebring 12 Hours in the same year (1982). It scored an unprecedented seven consecutive victories from Pocono in September 1981 through Charlotte in May 1982. From Sebring 1981 through Daytona 1983, it recorded an impressive nine wins and 16 podium finishes out of 27 races. It’s valued at $1.3 million to $1.8 million.

The1987 Porsche 962 IMSA Camel GT race car, powered by a turbocharged 3.2-liter engine and specially prepared for IMSA sprint events, affirmed its place as the fastest of the 962s when it finished third overall at the fifth round of the 1988 Championship at West Palm Beach. As the points-leading 962 of the 1988 season, DR1 is largely credited with clinching Porsche’s final IMSA Manufacturer’s Championship, beating Nissan by one point. Value is estimated at $1.2 million to $1.6 million.

RM’s Monterey sale also will include a selection of top road-going Porsches, including a hyper-performance 1998 Porsche 911 GT1 “Straßenversion,” the homologated street version of the 1997 GT1 race car. One of approximately 25 built and the only example known to be imported to the U.S., the 911 boasts a zero-to-60 time of 3.6 seconds and a top speed of 194 mph. The GT1 has just 7,180 kilometers (4,461 miles) on its odometer and is valued at $1.25 million to $1.4 million.

“Whether they’re looking for road or racing cars, Porsche enthusiasts are always extremely discerning as they look for quality cars with good history and authenticity,” said Rob Myers, chairman and founder of RM Auctions.“Our annual Monterey auction is a perfect venue for us to showcase the best and we’re delighted to present the ex-Jo Siffert 917/10 along with the tremendously successful 935 and 962 to our clients. The 911 GT1 alongside a number of outstanding road-going cars makes this offering all the more special.”
