We have had quite a series of stories from Porsche regarding its "issues" adapting to greener motoring. With that in mind, listen to this: Porsche might be thinking of installing 4-cylinder engines into some models. Well, to be precise, Thomas Krickelberg, Porsche's head of powertrain development, has revealed that the six-cylinder engines found in the 911 had been designed so that they could have the number of cylinders reduced to cope with the EU's CO2 regulations. How will the sports cars keep their power? Think of what Subaru does with its boxer turbocharged engines. Porsche's rumored downsizing is something we've heard before, though.

This type of downsizine is, more or less, what the Porsche 912 was about in the '70s. Porsche twice offered 4 cylinder engines for this model: as the entry version from 1965 to 1969, using the 4-flat "inherited" from the 356, and then again in 1976 as the 912E (refresh your memory about the "E" here) with a 2.0-liter aircooled engine. Hey, we even found an electric version of this one!
