Porsche fields two special Porsche 911 RSR at this year’s 24 Hours of Le Mans: The factory-run cars with the starting numbers 91 and 92 will compete sporting the traditional Le Mans liveries of the 1970s and 1980s. The #91 contender is decked out in the iconic blue-and-white finish with red and gold stripes, reminiscent of the Rothmans sponsor colours of that era. The #92 car adopts the famous “Pink Pig” design of the 917/20 from 1971. Porsche unveiled the two circa 510 hp racers from Weissach on Saturday at the official test for the Le Mans 24-hour race.
