FRANKFURT (Bloomberg) -- Porsche has won the famous Le Mans 24-hour endurance sports-car race for the first time since 1998 with a defeat of Audi, which triumphed in 10 of the 11 prior contests.
Porsche's 919 Hybrid car took first and second place, while Audi's R18 e-tron came in third, organizer Automobile Club de l'Ouest said in a statement. Both carmakers are owned by Volkswagen Group.
The return of Porsche to Le Mans in 2014 after a 16-year hiatus and its subsequent victory Sunday underscore how Volkswagen is stoking in-house competition on and off the racetrack, even amid additional costs. Porsche and Audi each entered three vehicles in the fastest vehicle category, Le Mans Prototype 1, or LMP1.
"This is a very special day for us," Matthias Mueller, Porsche's CEO, told reporters in Le Mans. "It was a great team effort."
VW is pouring money into new vehicles, technology and factories as the company plans to surpass global industry leader Toyota Motor Corp. by 2018. Maintaining a technological edge is vital for VW's upscale brands, which also include Bentley and Lamborghini, as they vie for affluent customers with the likes of BMW and Mercedes-Benz.
Audi and Porsche accounted for 66 percent of Volkswagen's operating profit in the first quarter. Volkswagen, which has one of the largest research and development budgets of any publicly traded company, is investing 85.6 billion euros ($96.1 billion) through 2019 to add models and production capacity.
Rising costs to develop electric cars and new features such as autonomous driving are weighing on Volkswagen's efforts to improve profitability. The manufacturer has taken steps to rein in costs companywide by sharing more parts among a wider range of vehicles.
Porsche and Audi have denied reports in recent weeks that they plan to enter Formula One car racing, citing high costs and shrinking visitor numbers. Formula One "needs to solve its problems alone," Rupert Stadler, Audi's CEO, said last month.
Audi and Porsche say Le Mans provides a better opportunity to test new technology that can be used later in road cars, such as lightweight construction and high-performance hybrid engines. Ford Motor Co., the second-biggest U.S. carmaker, said Friday it will return to Le Mans in 2016. Competing in the GT racing class, the U.S. company will commemorate the 50th anniversary of its 1966 sweep of the top three places at the race.
