The spied prototype displayed a rather unusual characteristic for a Zuffenhausen machine, namely shyness - the thing was fully covered in camouflage, so we couldn’t get a perfect look at the aerodynamic changes that will be introduced for 2015.
Nonetheless, chief among the revisions will be an even larger rear wing, as well as a pair of vents placed in between the taillights.
This racecar is powered by... mysteryAs for what goes on under that rear engine cover, this are as mysterious as they’ve ever been with Porsche. The current 911 RSR is motivated by a 4.0-liter flat six delivering 470 hp, being matter to a six-speed sequential race-spec transmission.
Certain wild rumors indicate that the RSR could go turbo to support the forced induction revolution that will be brought upon us by the 911.2 mid-cycle revamp, while others claim the racer will continue down the natural aspiration pathway.
It’s worth noting that the rules of the LMGTE PRO class where the 911 RSR competes allows both NA engines (up to 5,500 cc) and turbocharged mills (up to 4,000 cc). This is not the kind of story that deserves to be splattered with speculation, so we’ll be back as soon as we get our hands on more solid info.
