« There wasn’t much difference between the Porsche 911 and the 912 except for one crucial feature: the engine. While the 911 enjoyed a new air-cooled flat six, the 912 employed the air-cooled flat four used for so many years in the 356 to make it more affordable than the 911. As a result, enthusiasts traditionally haven’t viewed the 912 in as favorable light as the 911. But in 2014, as noted by Frenchman Julien Borne in this Petrolicious video(link is external), the 912 is coming into its own. »
