V12
The 65° V12 version of this engine was derived from the already extant V8. In the Ferrari Enzo, it had set the record for the most powerful naturally aspirated engine in a road car. The 5998 cc engine, designed for the Enzo, is known within Ferrari as the Tipo F140B, whereas the very similar Tipo F140C engine displaces 5999 cc and was designed for the Ferrari 599 as the most powerful series-production Ferrari engine. This engine is also used in Maserati Birdcage 75th.
