Five years. That's how long Audi has held on to the crown of the 24 Hours of Le Mans race. But on Sunday, Audi yielded the title to Porsche, who hasn't won the trophy since 1998. Porsche has just recently also returned to endurance race after 16 years of absence proving to be quite the surprise comeback. More than that, Porsche actually managed to nab five slots in the top five, with two of its cars earning the first two slots. Audi comes in at third and fourth.
