The constant low rumble about the coming Ferrari Enzo replacement over the past few years is beginning to rise into a roar as it draws nearer to production. The latest info ditches the twin-turbo V-8 idea and talks about a carbon fiber chassis.

The carbon fiber chassis is no surprise: that's where all of the stratospheric supercars are going these days, along with a few of the more "ordinary" sort. But the mid-mounted V-12 engine, as reported by Inside Line citing Ferrari CEO Amedeo Felisa, soundly crushes ideas of a twin-turbo V-8 or other power sources. The V-12 may yet be twin-turbocharged, however, and power is expected to tip in around 750 to 800 hp.

Of course, we don't get to know much more than that, except that Ferrari says it is currently testing prototypes. Hybrid technology, as previously reported, is still on the table.

We still don't know how long it will be until we see the Enzo's replacement, either, but our best guess puts it around 2014 at the earliest.
