Two Porsche sports cars, five decades separating their births. The elder is  a rolling testbed, an exercise in pushing the boundaries of competitive performance for a brand-new platform; the younger is a testament to 50 years of refining those engineering methods and dynamic principles set down by its forebear. One a single-minded weapon formulated solely to cement a new challenger’s position on the racing grid, the other a modern translation of that ruthless minimalism for the road with the help of modern construction advancements. Where the original was deemed too vicious in its time to merit more than twenty production units, both are now idolized by collectors and enthusiasts the world over for their shared philosophy of uncompromising athleticism, and both share a badge that inspires reverence in Porschephiles worldwide: 911R.
