On the scale of glorious engine noises, most anything produced by Ferrari sits near the top end of the scale. Be it the Dino-badged V-6 cars up through the V-8 engines on to the V and flat 12-cylinder units, the wonderful sounds that emanate from Ferrari tailpipes and engine bays is tantamount to pure joy in the ears of any lover of all things automotive. One of the great Ferrari cars is, of course, the Enzo, and it's 6.0-liter V-12. It's good for just over 650 horsepower and it revs to 8,000 rpm.

The new kid on the block is the LaFerrari. It's an evolution of the current design language, and it comes off as an Enzo from the future. This Italian spaceship for the road is powered by a 6.3-liter V-12 engine that produces nearly 800 horsepower and boasts a 9,000 rpm redline. There's also a KERS-style electrical motor system that adds in more juice when needed, and pushes the total horsepower figure up to 950.

Each engine is fantastic, but which one sounds better? YouTube user Marchettino recently got to find out, because he was able to line up each car in a tunnel... and then let his cameras roll as each car was revved a few times. In our opinion, the Enzo sounds a bit more evil but we do love the high-pitched, nearly F1-esque noises coming from the LaFerrari. Also, it's quite amazing just how much more quickly the LaFerrari engine can rev compared to the Enzo. Each is an astonishing car, but it's clear that the LaFerrari has come back in time from a future world filled with glorious noise and faster-revving V12 engines.
