car that finally stopped the McLaren juggernaut in Can-Am came from Germany via the workshop of a certain Roger Penske. The Porsche 917/10 took the title in 1972 with 1970 Trans-Am champ George Follmer at the wheel, after teammate Mark Donohue had been sidelined through injury. The following season the updated 917/30 debuted with a larger 5.4-litre flat 12 twin-turbocharged engine capable of producing in excess of 1100 horsepower, with two cars bound for Penske and another for the European equivalent, the Interserie. Having worked closely with the Porsche factory in the off season with his own brilliant engineering input Donohue went on to demolish the competition and capture back to back titles for Penske. Back in Germany work on three new chassis commenced for use in the forthcoming 1974 season, but then abruptly halted when the Sports Car Club of America changed the fuel use regulations, effectively killing off the unlimited power outputs and eventually hastening the demise of Can-Am itself. In 1979 Florida Porsche dealer and collector Gerry Sutterfield stumbled across the three partly completed chassis during a visit to the factory and hatched a plan. Porsche themselves completed the build on chassis 005 utilising an original spec engine found in storage and suspension from the then current 936 Le Mans racer which employed suspension based on the 917/30 to begin with. The car took pride of place in Sutterfields showroom for a few Lola T163 years until passing through collections in Sweden, Japan and the US. Queenslander Harburg acquired it in 2011 and gave it that famous Penske/Sunoco livery. The other two chassis were also built up with 004 having an Aussie link with its first owner being Alan Hamilton in the late 1970s. Later funny man and certified Porsche freak Jerry Seinfeld added that car to his impressive collection before selling it recently for USD$3 million dollars. With only six chassis in total ever constructed, Harburg is to be admired for letting race fans share in the thrill of seeing the most powerful sports racer ever built in action. wanted to move this car on quickly. I made a sharp offer and the deal was done. I have put it back to exactly how it was with a genuine alloy 430 Chev. The Americans aren’t fussed over originality as they let over size engines and extra aero on cars that never had them. Last year I raced it on consecutive weekends at Mid- Ohio and Road America, tracks that hosted Can-Am events originally and are unchanged except for better fencing. They are fantastic. At Road America I told a guy there that there were corners that were exactly the same as corners at Amaroo, Oran Park and Lakeside. All four circuits were built in 1961. It is a handful with a short wheelbase, 780bhp and no aero. We were still fastest of the earlier non downforce cars at Road America.” Roger Penske commissioned Lola to build this chassis for Mark Donohue to take on the dominant McLarens in 1969. With Penske running cars in Trans-Am, Indycar and long distance sports cars at the same time development was non-existent and it showed. The Lola broke rear axle half shafts in practice, qualifying and nine laps into its first race at MidOhio. Penske immediately cancelled his Can-Am attack and sold the car to Eno de Pasquale who put it on static display while he raced another chassis, finally selling the Penske car in 2008.
