Why did Ferrari pick a wide 120-degree angle for the 296 GTB's V6 when it wanted the engine to sound like a small V12?

Answer: A 120-degree V6 fires at perfectly even intervals, so the exhaust pulses stay evenly spaced and clean

A 120-degree V6 fires at perfectly even intervals, so the exhaust pulses stay evenly spaced and clean ✓ — Correct! Ferrari's 120-degree V6 fires its cylinders at perfectly even intervals, a symmetry that narrower V6 layouts cannot give. Equal-length tuned exhaust manifolds then amplify those evenly spaced pressure waves, so the harmonics stay clean all the way to 8,500 rpm, and a resonator tube carries that character into the cabin. The wide angle also leaves room for the turbos between the banks, but the sound case rests on the even firing.

A wider angle makes the engine note deeper, the way a longer horn plays lower — Wrong. Pitch comes from how often the cylinders fire, so engine speed sets the note, not the angle between the cylinder banks. What the wide angle changes is the rhythm: on a V6, 120 degrees spaces the firing events evenly, which is about regularity and harmonic purity, not about making the note lower.

It lets the exhaust pipes be shorter, and shorter pipes keep the sound purer — Wrong. Shorter pipes change packaging and flow losses, but shortness alone does not make a sound purer. Ferrari's sound claim rests on the symmetrical firing order and on equal-length manifolds that keep the pressure waves in step; the mechanism is organised pulses, not simply less pipe.
