Porsche Cars North America (PCNA) and Mazda Raceway Laguna Seca have announced that Porsche Rennsport Reunion IV will be held at the famed California racetrack the weekend of October 14-16, 2011.

After successfully staging the event, which is held every three years, at three venues in the east, with the first held in Lime Rock in 2001, Rennsport Reunion IV will now be moving to the west. This announcement is great news for the vast array of car aficionados and Porsche enthusiasts that live closer to the Pacific coast.

Rennsport Reunion IV brings together an unprecedented gathering of notable Porsche vintage and current race cars, as well as those who have driven them to victory at the world’s most famous sports car races. The three-day event of on-track competition is complemented by a concours d’elegance, which is open to invited race participants, as well as special activities celebrating the decades-long history of the legendary 911 race cars.

“While the Rennsport name has become a staple fixture for international collectors and racers over the past ten years, choosing the Monterey Peninsula will open up this one-of-a-kind gathering to many Porsche fans in California and beyond who were previously unable to attend,” said Detlev von Platen, president and CEO of Porsche Cars North America. “Now they’ll have the opportunity to see, feel and hear, from up close, hundreds of famous Porsche race cars and dozens of their drivers from past and present during a truly memorable weekend dedicated to Porsche’s motorsport heritage.”

Porsche Rennsport Reunion IV will bring together a variety of Porsche’s most historic racing models from the nimble 550 Spyder of the mid-50s through the mighty 917 and 956/962 of the 70s and 80s to the highly successful GT3 RSR of the last decade. A special tribute will be paid to the numerous racing versions of the Porsche 911 and the countless victories won over the decades.

“This will truly be a rare gathering of significant Porsche race cars on the West Coast,” commented Gill Campbell, CEO and general manager of Mazda Raceway Laguna Seca. “Porsche has a long racing tradition in Monterey and we look forward to celebrating its heritage in a befitting manner for everyone to enjoy.”

Porsche and Mazda Raceway Laguna Seca are working in association with the Porsche Race Car Classic to combine efforts to raise awareness for the Bonnie J. Addario Lung Cancer Foundation and the UCSF Thoracic Oncology Program.

Therefore, complementing the Rennsport Reunion IV event is the Porsche Race Car Classic which is exclusive concours held at nearby Quail Lodge in Carmel on Sunday, October 16. Steve Heinrichs, producer of the Porsche Race Car Classic, explains, “This once-in-a-lifetime gathering of vintage Porsche race cars solely from Porsche’s break-out era of 1950-1965 will raise critical funding to directly support lung cancer research. We’ll have 550s, 718s, 804s, 904s, 356s, Abarths, and more, in numbers and provenance never before seen.”
