The car was first displayed at Geneva on March 12, 1969.   

Development of the 917 commenced in July of 1968 in complete secrecy to avoid leaked information of its existence reaching Porsche’s number one competitor – Ferrari.

The Spa 1000km of 11 May 1969 saw the 917’s competition debut.

The car was initially deemed “incredibly unstable” by development driver Brian Redman and “extremely dangerous” by Hans Herman. 

However an intense development programme through 1969 saw the car ultimately developed into one of the most successfully race cars of all time. It went on to win Le Mans in 1970 and returned in ’71 with the Martini and Gulf-Wyer teams to completely dominate the event.

The Long Tailed Le Mans racer was capable of 0-100km/h in 2.5 seconds and a top speed of 406km/h

The Gulf Team livery 917 was immortalised by Steve McQueen in the 1971 film Le Mans. It has since that time -- along with the Bullit Mustang -- become one of the two most iconic movie cars.

For the 1973 Can-Am series, a turbo-charged version was produced; developing 820kW in race tune and 1180kW in qualifying tune.  This version, the 917/30 could accelerate from 0-100km/h in 1.9 seconds and 0-160km/h in 3.9 seconds, hitting a top speed of 414km/h.

Mark Donohue set the land speed record for a closed circuit in a 917/30 at Talladega Sperspeedway in 1975. The average speed was 356 km/h and the record stood for four years.

The Porsche 917 is one of the most significant race cars of all time with current (2009) values at between $3 million to $7 million.

unless you have balls of steel, you need not apply to purchase this car....

Porsche 917's honored at Laguna Seca

Doug McDonald

When you think of the name, Porsche, you can’t help but think of its racing history and heritage. Started in a barn in a little village called Gmund, in the mountains of post-war Austria, this engineering, design, and car manufacturer has held almost every competitive title you can think of. The nascent company’s engineering built upon itself and became better and better with each passing year to become what it is today.

Some say the pinnacle of Porsche’s legendary engineering created a racecar so spectacular and powerful that if it had wings it would fly. This particular car has an almost cult-like status among its fans and that car, at its birth in 1969, was given the designated number of 917.

2009 marks the 40th anniversary of the 917. This racecar left little latitude for error as it was produced not for driver safety but for maximum speed. Its mission in life was to barrel down the Mulsanne straight at LeMans at speeds exceeding 230mph.

The 917 had a competitive life of only a few years (1970-1975). One reason that the 917 enjoys great fanfare today is not only that it starred in the 1971 movie LeMans with Steve McQueen, it won races and lots of them. So many in fact the 917 programs fell apart more to rule changes through FIA, SCCA, and Can-Am series races than to outdated technologies.

At this years Monterey Historics a tribute was made to the 917 and several beautiful examples powered around the track including a pristine 917k owned by Jerry Seinfeld (a huge Porsche fan if you didn’t know) and a Gulf-liveried, 917k, owned and driven by Bruce Canepa from Scotts Valley. England enjoyed a similar ceremonial race for 917’s this year at the Goodwood Festival of Speed in early July.

The 917 came with three power plants depending on the configuration: 4.0 liter, 4.5 liter and up to 5.0 liter. A Flat 12 cylinder engine powered the car and was air cooled by a massive power-sucking fan on top of the motor.

The 1970’s became the dawn of aerodynamics and little was known except for what was learned during the war with combat aircraft. Built in both short and long tailed styles both types of cars had their inherent problems. The long tail design became Porsches solution for the short tailed cars anti gravity tendencies, but unfortunately it had the opposite effect. The tail at high speed created lift and would send the car flying off the track and unfortunately killed a few drivers.

917’s were Porsche’s money-no-object attempt to win titles in international racing events and its engineering was revolutionary as opposed to previous designs that were more evolutionary. To this day Porsche engineering wins races and championships around the world every race season. The 917 has certainly earned its place in the sports car hall of fame. Happy birthday!
