We last heard the V10 scream in 2005. From 2006 onward, F1 switched to 2.4‑litre V8s, and the soundtrack was never quite the same. So why do so many fans—and even drivers—insist that the historic V10 is the best‑sounding engine of all time? It isn’t just nostalgia; there’s solid science behind it.
Over the past two decades F1 has gone from 10 cylinders to 8 and now to 6‑cylinder turbo‑hybrids. The sound has shifted from razor‑sharp and piercing to deeper and more subdued. In part, sustainability targets have changed the character of the sport’s acoustics. Back in the early 2000s, the rules mandated a 3.0‑litre V10. That layout wasn’t an accident: allocating roughly 0.3 litres per cylinder struck a sweet spot between achievable revs and mass. The result was engines that could spin to around 20,000 rpm while maintaining a workable level of reliability.
Why does a V10 sound so good? Most of the noise you hear comes from the internal‑combustion engine and the exhaust system. When high‑temperature, high‑pressure gases are expelled through the exhaust manifolds, they generate pressure waves across a range of frequencies. Change the firing order and the tone changes with it; when cylinders on opposite banks alternate left‑right firing, you get that signature, rolling roar. Firing interval matters, too: if the intervals are even, the outgoing sound contains a steadier fundamental frequency and overtones, which our ears perceive as cleaner and less fatiguing than constantly shifting, irregular spectra.
As you open the throttle, rpm and therefore the frequency of the sound increases—hence the rising, needle‑sharp pitch at high revs; at lower revs the tone is fuller and bass‑heavier. F1 engines typically operate anywhere from ~9,000 to ~19,000 rpm, creating an alternating blend of highs and lows that feels musical rather than chaotic.
A single cylinder by itself doesn’t sound particularly pleasing. Add a second cylinder and the top end becomes brighter while the low end gains depth; add a third and the combined waveform starts to resemble a musical perfect fifth. Keep stacking cylinders and, by the time you reach ten, you get an unusually consonant harmonic structure—a small acoustic miracle.
In theory, engines whose cylinder counts are multiples of five emphasize fifth‑order harmonics that align with a major‑third interval—one reason that combination feels especially uplifting to our ears. The V10’s harmonics blend naturally and flow smoothly, which our brains interpret as pleasant.
By contrast, classic V8s and V12s don’t quite land on the same harmonic relationships; they aren’t multiples of five, so they don’t reinforce the same perfect‑fifth/major‑third pattern, and their spectra lack that particular consonance. Today’s turbo‑hybrid V6s take an additional hit: turbochargers act like partial mufflers and reshape the exhaust pulse, further dulling the clarity. That’s why, to many, the V10 era remains the gold standard for F1 sound.
