Dec.2 (GMM/Inautonews.com) Ferrari may already be testing a version of its 2014 turbo engine, according to internet rumours.

Over the weekend, a video emerged on the internet depicting a LaFerrari supercar lapping the Fiorano circuit amid the distinct tones of a turbo engine.

That Ferrari road car, however, is usually equipped with a normally-aspirated V12 engine.
