There was much consternation over potential changes to the track-focused, top-of-the-line neunelf (that’s German for “911”) before its release. Would Porsche move the engine from Ferdinand Porsche’s anointed rear-placement? Would turbo-charging be utilized? In the end, the answer was no to both questions. The latest GT3 RS is naturally-aspirated and the incredible 4.0-liter flat-six is in the rear, where it was meant to be. Adding to 500 horsepower and its screaming-high redline, the RS is 22 pounds lighter than the already lithe GT3. Rear-wheel steering and all the accouterments of the best track car on the planet are also right where they should be.
