One of the biggest turning points in the Porsche 911’s long history came in 1998. That’s when the last air-cooled 911 rolled off the assembly line, effectively splitting the 911 hierarchy into two distinct eras: air-cooled and water-cooled. To this day, the most dedicated Porsche purists remain devoted to air-cooled engines, so much that they’re willing to pay big money for restomod 911s combining modern performance with old-school air-cooled power.But what if it didn’t have to be that way?CarBuzz has uncovered a patent from Porsche featuring a new engine design that relies heavily on air cooling to function. It’s not entirely air-cooled, but it could well be the closest thing we’ll ever see to those old waterless engines in a new, from-the-factory format.
