PORSCHE RACING HISTORY917 K/81
In the late 1970s Erwin Kremer of Germany's celebrated Kremer Racing, is wandering around the U.K's Midlands Motor Museum when he spots among the exhibits chassis 917-13, the car once raced by Mexican star Pedro Rodriguez. Although the 917 was officially defunct, Kremer experienced a light bulb moment that inspired him to think that the short-lived but famous racer could not only be revived but be re-designed and sufficiently improved to become a competitive force at Le Mans once more – this time by taking advantage of the transitional period between the demise of the Group 5 and Group 6 race categories and the impending arrival of the new Group C in 1982.
