There’s something about a great-sounding engine that stirs the soul of every car enthusiast. Whether it's the raspy bark of a high-revving V10 or the deep growl of a classic V8, the engine’s sound is one of the most emotional aspects of the driving experience.

 

Why Do Some Engines Sound Different?

That iconic roar, howl, or purr comes down to a range of engineering and design decisions made during development of an engine. While performance is the main goal, the sound has become a badge of honour, especially for petrol heads who love revving through tunnels or straights.

What Determines the Sound of a Car Engine? 

Several factors influence what an engine sounds like. It’s not just about displacement or horsepower, it’s about how the engine breathes, fires, and releases gases.

Cylinder Count:

More cylinders typically mean more pulses of combustion per cycle, which affects both the tone and the smoothness. A 12-cylinder engine often sounds smoother and more melodic than a four-cylinder, while a five-cylinder might sound oddly off-beat.

Engine Configuration (V vs Inline):

Inline engines tend to produce a smoother, more balanced sound, while V-shaped engines (like V6s, V8s, V10s) often deliver a throatier and more aggressive growl. Flat engines (like those in some Subarus and Porsches) have their own unique rumble too.

Exhaust Setup:

The exhaust system plays a critical role. From pipe length and diameter to muffler and resonator design — these components can make a quiet engine sound like a beast or vice versa.

Crankshaft Design (Flat-Plane vs Cross-Plane):

A flat-plane crankshaft (often found in Ferraris or the Ford Mustang GT350) gives a sharper, higher-pitched sound, while cross-plane crankshafts (like those in American V8s) provide a deep and burbly tone.

Why Do V8 Engines Sound So Good? 

V8s are the sound of power and presence. With their even firing intervals (in cross-plane form) and balanced design, they produce a deep, rhythmic rumble that hits you in the chest.

Whether it's the burble of a classic muscle car or the refined thunder of a Mercedes-AMG, V8s deliver the perfect blend of grunt and drama.
