Porsche has registered a patent for new air-cooled engine technology.

The system won't be fully air-cooled, but it would be a drastic change to current Porsche systems.

The engine would sit inside a nearly fully encapsulated air duct, while a large fan channels air over the radiator, engine, turbochargers, and exhaust.

An air-cooled Porsche remains a dream collector's item for many a car enthusiast. Porsche built air-cooled 911s right up until 1998, as the 993-generation 911 gave way to the water-cooled 996-generation car.

Interestingly, Porsche purists might have some intriguing news for those looking to get back into an air-cooled setup. The German sports car maker has filed a patent for a whole new air-cooled setup, and it brings the old-school tech into the modern day.
