Spotted on the Nürburgring: A Porsche Boxster and a Porsche Cayman. Normally, this would be an unremarkable occurrence. Except they sound quite a bit different than the last Cayman I drove. Maybe even two fewer cylinders different.

That's what the intrepid 'Ring watchers at Touriclips think, too. They're also pretty certain that's not the flat-six Cayman and Boxster rumble we're used to hearing. I think it's higher-pitched than that.

We know that Porsche is planning a new line of four-cylinder engines, likely flat fours, to debut in their cars over the next few years. I would not be surprised at all if these are the motors being tested here.

What does everybody think of that sound? Is a four-banger Cayman and Boxster something we can get behind?
