Id love to see Porsche return to Le Man with an LMP1 car, as i would Ferrari too (its been wwaaayyy to long but highly unlikley)
The 917 ranks up there as one of, if not my favourite race cars of all time, and their other Le Man runners of yesteryear also was as goog looking as they were competitive, and Id love to see what Porsche could do in 2014. I wonder how Porsche, if they did return, would power their cars. Surley they have the finances and R&D to get a Petrol car on par with the Audi & Peugeot diesels.
With the advent of the forthcoming FIA World Endurance championships (which should just be called Sportcar championship), this could be very likley for Porsche (and other manufacturers like Nissan and Toyota) to return to endurance racing. And i hope so.
