The fact that Porsche->ke1 is busy working on a turbocharged, four-cylinder powerplant that will find its way in the Boxter->ke570 and Cayman is no longer a rumor. The Stuttgart crew confirmed->ke506 it last month, stating that the company is doing so in order to join the eco-friendly trend the automotive industry has embarked on in the 21st century.

Little is known about the new four-pot at the time of this writing, but word from Porsche CEO Matthias Mueller says that the new unit will pump about 395 horsepower into the aforementioned sports cars->ke506. At the same time, the official suggested that the said four-cylinder engine won't be sourced from the 919 Hybrid race car->ke148.

More details are likely to surface later this year, but until then there's an interesting spy video that we'd like to share with you. At first glance it's "only" about a facelifted version of the Porsche 911->ke282 lapping the Nurburgring->ke999, but the trick is to pump up the volume and put your ears to good use.

What you hear might very well be the new four-cylinder engine everyone's been talking about lately. It appears that Porsche is already testing it, albeit in a 911->ke282. Don't worry though, the Germans aren't foolish enough to ruin their flagship sports car and take that brilliant flat-six away from it.
