Well, neither the 919 or the 991 RSR fared very well in this years Le Mans, but the 919 is radically new technology(pushing a 4-Cylinder to compete with a V-6 and a V-8) which will undoubtedly alter the future of automotive technology(as will the 918), & Porsche makes a fortune selling and licensing intellectual properties to the automotive world.
911 RSR was effectively 'neutered' after Silverstone with a balance of performance 'adjustment', but that's the breaks after winning last year in it's class at Le Mans, and Daytona, and Sebring and another 1-2 in the first FIA-WEC race. Luck also is a variable no one has control of, so the spoils have to go elsewhere this year on the big race.
Just as the original 917 debut, the 919 will greatly benefit another year of development, and we may even see a 4-way battle next year as Nissan is trying to bring the GTR into the fray. All good stuff!
